Heart Attack Misdiagnosis Claims in Ireland: When Hospitals Break Their Own Rules
Author: Gary Matthews, Principal Solicitor • Law Society of Ireland PC No. S8178 •
3rd Floor, Ormond Building, 31-36 Ormond Quay Upper, Dublin D07 • 01 903 6408 •Heart attack misdiagnosis in Ireland is a failure to identify or act on a cardiac event within the time-critical standards set by the HSE's own clinical programme. The NOCA Irish Heart Attack Audit 2024, published on 10 February 2026, found that only 35% of patients arriving at a PCI centre received an ECG within the target 10 minutes. That figure drops to 28% in non-specialist emergency departments. Only 61% of patients received primary PCI within the recommended two hours after diagnosis. These aren't just statistics. Each delay point is a measurable breach of the standard of care that can ground a negligence claim under Irish law.

The "Golden Hour": what standard of care actually means in Ireland
Heart attack misdiagnosis claims in Ireland are measured against the specific protocols of the HSE National Clinical Programme for Acute Coronary Syndrome (ACS), not a vague idea of "reasonable care." The legal test is set by Dunne v National Maternity Hospital [1989], which asks whether a competent doctor of equal specialisation, acting with ordinary care, would have done what the defendant did. For cardiac cases, the answer comes from concrete benchmarks. Unlike in England and Wales, where the Bolam test allows a doctor to rely on any responsible body of medical opinion, Irish law under Dunne permits a court to find negligence even where a practice is "general and approved" if it has inherent defects that should be obvious.
The HSE's ACS Programme sets three time-critical targets that define what "ordinary care" looks like in an Irish emergency department. First, an ECG must be performed and interpreted within 10 minutes of first medical contact. Second, for STEMI (the most serious type of heart attack), the patient should reach a catheterisation laboratory for PCI (angioplasty) within 90 minutes. Third, reperfusion therapy should be delivered within 120 minutes of first medical contact at most. These targets are set out in the NOCA Irish Heart Attack Audit 2024 and the HSE ACS clinical programme.
A detail that catches many claimants off guard: these targets aren't aspirational. They're the HSE's own published benchmarks, developed from international evidence. When the Dunne test requires a court to determine what a competent cardiologist would do, the answer points straight back to the protocols the hospital was already supposed to follow. The protocol breach becomes the breach of duty. Ireland has 10 designated PCI centres capable of performing emergency angioplasty, and the ACS Programme has been operational since 2012, as documented by the NOCA 2024 audit.
Those centres are not evenly distributed. In February 2026, the HSE's National Heart Programme confirmed an action plan to address the audit findings, including a proposal to designate University Hospital Waterford as the seventh 24/7 PPCI centre. Medical Independent (Feb 2026). The current configuration matters for your claim, because it determines whether the hospital that treated you was equipped to perform emergency PCI or should have transferred you immediately.
| Centre | Region | 24/7 PPCI |
|---|---|---|
| Mater Misericordiae University Hospital | Dublin North | Yes |
| St James's Hospital | Dublin South/Midlands | Yes |
| Cork University Hospital | South | Yes |
| University Hospital Galway | West | Yes |
| University Hospital Limerick | Mid-West | Yes |
| University Hospital Waterford | South-East | Designated for 24/7 expansion |
| Altnagelvin Hospital, Derry (NI) | North-West (Donegal) | Yes (cross-border) |
Additional PCI-capable hospitals (not designated 24/7 PPCI): Beaumont Hospital, Tallaght University Hospital, St Vincent's University Hospital. These can perform PCI for walk-in patients during working hours but are not part of the emergency STEMI network. Sources: NOCA 2024 audit, Medical Independent (Feb 2026).
The Donegal arrangement is unusual. Before May 2016, STEMI patients presenting to Letterkenny University Hospital faced a 3.5-hour transfer to Galway or 3 hours to Dublin. A cross-border agreement now routes them to Altnagelvin Hospital in Derry, just 32.5 km away. IJIC (2017). If you had a STEMI in Donegal and were not transferred under this protocol, the referring hospital's failure to activate the cross-border pathway is itself a potential breach.
A patient in rural Kerry, West Cork, or the midlands may still face a transfer of 90 minutes or more before reaching a catheterisation laboratory. That transfer time directly reduces myocardial salvage: the amount of heart muscle that can be saved by reopening the blocked artery. The gap between a Dublin patient's access to emergency PCI and a rural patient's access creates a measurable difference in clinical outcomes, and in the strength of a negligence claim where the referring hospital delayed the transfer decision.
NOCA 2024 audit: the numbers that prove systemic failure
The NOCA Irish Heart Attack Audit 2024, published on 10 February 2026, reviewed 1,615 STEMI patients treated across Ireland's 10 PCI centres and their referring hospitals. The data reveal systemic delays that affect the majority of patients.
| Measure | HSE target | 2024 result | Gap |
|---|---|---|---|
| ECG within 10 minutes (PCI centre) | Target: all patients | 35% | 65% did not meet target |
| ECG within 10 minutes (non-PCI ED) | Target: all patients | 28% | 72% did not meet target |
| Primary PCI within 2 hours of diagnosis | Target: all STEMI patients | 61% | 39% outside target |
| Primary PCI delivered (of eligible patients) | 100% of eligible | 77% | Down from 86% in 2017 |
| "Door In Door Out" (non-PCI hospital, 30 min) | 30 minutes | 3% (12 patients) | 97% exceeded target |
| Transfer to PCI within 90 min of first contact | 90 minutes | 26% (106 patients) | 74% exceeded target |
| Door-to-Balloon (ambulance arrivals at PCI) | 30 minutes | 55% | 45% outside target |
Source: NOCA Irish Heart Attack Audit 2024, Irish Medical Times (Feb 2026), Irish Examiner (Feb 2026).
The audit also found that STEMI mortality in Ireland has halved from approximately 7.4% to 4.1% over the past decade, saving hundreds of lives. Yet the data show performance is slipping, not improving, on several key measures. Primary PCI delivery has dropped from 86% in 2017 to 77% in 2024, according to the NOCA 2024 audit.
One aspect the official guidance doesn't cover: what these figures mean for your case. If you waited 40 minutes for an ECG in a Dublin emergency department, the audit confirms you were likely among the 65% who didn't receive timely assessment. That turns a subjective feeling of "they took too long" into a documented, systemic failure measurable against the HSE's own published standards.
The State Claims Agency's own data reinforces this. Diagnosis-related claims ranked second by volume of all clinical claims received by the SCA in 2023, with an estimated liability of close to €110 million for publicly funded acute care alone. SCA Diagnostic Incident Reporting (2024). Cardiac misdiagnosis sits squarely within this category. When the SCA flags diagnostic errors as a leading driver of clinical claims, it confirms that the problem your case describes is not isolated but part of a pattern the State's own risk managers already track.
The broader financial picture matters too. Outstanding clinical claims managed by the SCA carried an estimated liability of €5.35 billion at the end of 2024, up from €3.85 billion at end-2022. That earlier figure represented a 270% increase over the preceding decade. BMJ Open Quality (2023); NTMA Annual Report 2024. Because the HSE reimburses the SCA for settlements and associated costs from the healthcare budget, the financial pressure to resolve claims rather than contest them at trial is significant. Legal costs account for approximately 24% of the total cost of the average clinical claim. This context doesn't guarantee any particular outcome, but it frames the environment in which cardiac negligence claims are assessed and settled in Ireland.
How heart attacks are missed in Irish emergency departments
Heart attack misdiagnosis in Ireland typically follows one of four patterns: triage misclassification, differential diagnosis error, premature discharge after incomplete testing, or results management failure. Understanding which pattern applies to your case determines how the claim is built.
The "indigestion" error
The most common misdiagnosis is labelling cardiac chest pain as gastro-oesophageal reflux (GORD), particularly when the patient describes a "burning" sensation. An inferior myocardial infarction can present with upper abdominal discomfort that closely mimics acid reflux. The breach occurs when the clinician treats the symptoms as digestive without first performing an ECG and ordering serial Troponin blood tests to rule out a cardiac cause. Under the Dunne principles, the standard requires ruling out the life-threatening condition before treating the benign one.
The "panic attack" error
Diagnostic overshadowing occurs when a doctor assumes a psychological cause based on patient history or presentation, without excluding an organic cause first. A patient with a history of anxiety who presents with chest tightness, breathlessness, and sweating may be labelled as having a panic attack. The breach is the failure to perform objective cardiac testing before assuming a psychiatric explanation. Forum discussions on boards.ie and Reddit's r/ireland repeatedly describe this pattern, particularly affecting younger patients and women, consistent with findings from the Croí/Global Heart Hub survey (2025).
The missed transfer
Patients who first present to a non-PCI hospital (one that can't perform emergency angioplasty) depend on rapid transfer to one of Ireland's 10 PCI centres. The NOCA 2024 audit shows that only 3% of patients transferred from non-PCI hospitals achieved the recommended 30-minute "Door In Door Out" time. Only 26% reached a PCI centre within 90 minutes of first medical contact. Each minute of delay beyond the target increases the area of heart muscle that dies.
The chain of delay can start even earlier. The National Ambulance Service's PURPLE calls (life-threatening cardiac or respiratory arrest) averaged a 24-minute response time across the Republic between January and November 2025, against a target of reaching 75% of such calls within 18 minutes 59 seconds. Irish News (Jan 2026). In 2023, 1,108 patients were already deceased by the time the ambulance arrived, up 70% since 2016. Irish Examiner (Feb 2024). Hospital handover delays compound the problem: when ambulances are stuck at A&E unable to offload patients, they cannot respond to the next cardiac call in the community.
Pre-hospital delay can form a separable negligence angle. If the ambulance took 40 minutes to reach you, and then the non-PCI hospital took a further 50 minutes to arrange transfer, the total delay from first call to PCI may exceed three hours for a condition where the HSE's own target is under two. The ambulance logs, the hospital transfer records, and the catheterisation lab timestamps form a continuous evidence chain. The HSE is the defendant for both the ambulance service and the public hospital.
There is a fallback the protocol requires. The HSE's Optimal Reperfusion Service states that if a STEMI patient cannot reach a PCI centre within 90 minutes, thrombolysis (a clot-dissolving drug) should be administered instead, followed by prompt transfer. The HSE's February 2026 action plan now targets thrombolysis within 10 minutes of diagnostic ECG in remote areas, as reported by Medical Independent (Feb 2026). If a non-PCI hospital neither transferred you within 90 minutes nor gave thrombolysis, that is two protocol breaches in the same episode: a failure to provide the primary treatment and a failure to provide the mandated alternative. Both are documentable from the hospital records.
The results gap
GP referrals and hospital test results can fall into a gap where nobody acts on them. A GP orders blood tests, the results show elevated cardiac markers, but the report sits in a filing system or electronic inbox without being reviewed. The State Claims Agency has identified "results management" as a recurring pattern in clinical claims. If the practice lacked a fail-safe system to catch unreported abnormal results, the practice itself may be liable.
Ireland's lack of a national electronic health record makes this worse. Ireland is one of only four EU countries without a fully functioning EHR system, and one of five without ePrescription, according to BMJ Open Quality (2023). The SCA has specifically flagged the absence of an integrated EHR as a concern, because the adequacy of records is a major issue in clinical claims. For a cardiac patient, this means the GP notes, ambulance patient report form, A&E triage record, ECG printouts, laboratory results, and catheterisation lab data may all sit in separate, disconnected systems. Reconstructing the timeline for a negligence claim requires obtaining records from each source individually, and gaps between systems are where critical handover failures hide.
The Troponin trap: why one blood test doesn't rule out a heart attack
Troponin is a protein released when heart muscle cells are damaged. Troponin levels rise over time, not instantly. A patient whose first blood test at arrival shows a normal Troponin level may still be having a heart attack, because the protein hasn't yet peaked in their bloodstream.
The standard of care in Ireland requires serial Troponin testing, typically at 0, 3, and 6 hours after symptom onset, to track the "delta" (the change in concentration over time). Discharging a patient after a single negative Troponin result, without waiting for the follow-up tests, is a specific and provable act of negligence. The breach isn't "missing a diagnosis." The breach is discharging a patient before completing a testing protocol that would have revealed the diagnosis.
The difference between assessment and acceptance in Troponin claims comes down to timestamps. Your medical records will show when each blood draw occurred, what the result was, and when you were discharged. If the discharge happened before the serial testing was complete, that gap in the timestamps tells the story.
NSTEMI: the majority of missed heart attacks
The NOCA audit covers STEMI only, which accounts for roughly 20% of heart attacks. The remaining 80% are NSTEMI (non-ST-elevation myocardial infarction). NSTEMI patients are far more likely to be sent home with a missed diagnosis, because their ECG may look normal or show only subtle changes. The diagnosis depends entirely on serial Troponin testing and clinical judgment.
This matters for claims because the majority of people searching for "heart attack misdiagnosis" experienced an NSTEMI. They went to A&E with chest pain, had a normal-looking ECG, received one Troponin test that came back within range, and were discharged. The heart attack was only confirmed days or weeks later when they re-presented with worsening symptoms or when a follow-up blood test or echocardiogram revealed the damage. The breach in an NSTEMI case is the same as in a STEMI case: failing to complete the serial Troponin protocol before discharge. The difference is that without a dramatic ECG finding, the urgency is less obvious to the treating clinician, which is precisely why the protocol exists as a safeguard.
NSTEMI claims can be harder to prove than STEMI claims, because the diagnosis is inherently less clear-cut at the point of initial presentation. But they are not weaker claims. If the protocol required serial Troponin at 0, 3, and 6 hours, and you were discharged after a single test at 2 hours, the breach is binary: the protocol was not completed. A consultant cardiologist can then assess whether completing the protocol would have revealed the diagnosis and prevented the additional damage.
Women and cardiac misdiagnosis: why the system fails them
Women in Ireland are significantly more likely to have a heart attack misdiagnosed, because their symptoms often differ from the "textbook" presentation that clinical training has historically prioritised. A Croí/Global Heart Hub survey (March 2025) of 502 Irish women found that only 3% could name all relevant heart attack symptoms. Less than 1% could name them without also naming incorrect ones. Half of the women surveyed were unaware that heart attack symptoms in women may differ from those in men.
One in four Irish women die from cardiovascular disease, according to Croí. That's approximately 4,000 women each year. Women often describe chest pain as pressure or tightness rather than crushing pain, and are more likely than men to experience jaw pain, neck pain, shoulder or upper back pain, nausea, unusual fatigue, and shortness of breath. Women also wait an average of 37 minutes longer than men to seek medical help during heart attacks, according to research published by the European Society of Cardiology (2018), cited by Croí.
The legal point is this: when a woman presents to an Irish emergency department with jaw pain, nausea, and breathlessness, the standard of care requires the same cardiac workup (ECG, serial Troponin) as for a man with crushing chest pain. If the doctor treats those symptoms as anxiety, menopause, or musculoskeletal pain without cardiac testing, that's a measurable deviation from the expected standard.
The NOCA 2024 audit also noted that women who smoke experience heart attacks on average 13 years earlier than women who don't (age 61 vs 74). People under 40 who suffer a STEMI are three times more likely to be smokers than older patients (64% vs 21%), according to the NOCA 2024 audit. The patient profile of a 44-year-old woman with atypical symptoms doesn't match the "Hollywood heart attack" stereotype, but it absolutely matches the clinical reality. Younger patients and women are the demographics most likely to be misdiagnosed, and most likely to have a viable claim when they are.
Proving your case: the forensic cardiac audit
Heart attack misdiagnosis claims in Ireland require an independent consultant cardiologist's report, not a GP report, to prove breach and causation to the standard required by Irish courts. The expert reconstructs what happened from the medical records and measures each step against the HSE protocol benchmarks.
The forensic audit focuses on five areas:
1. Triage category. The expert checks the category assigned on arrival and whether it matched the presenting symptoms. A patient reporting chest pain who receives a lower-priority triage rating may have been misclassified from the outset.
2. ECG timing and interpretation. The audit compares when the ECG was performed against the arrival timestamp, and whether it was read correctly. Automated ECG machines produce an interpretation, but the clinician must also read the trace. A subtle ST-segment change that the machine flags but the doctor overlooks is a documentable error.
3. Troponin protocol. The expert verifies whether serial Troponin tests were ordered at the correct intervals, whether the patient was discharged before the delta could be measured, and whether results were acted upon promptly.
4. Referral and transfer decisions. For non-PCI hospitals, the audit checks whether transfer was arranged without delay and whether the ambulance service and receiving hospital were notified promptly.
5. Discharge decision. The expert assesses whether the discharge was appropriate given all available information at that time, and whether the patient received adequate safety-net advice. Safety netting is a recognised clinical obligation, not an optional courtesy. It means giving the patient written discharge instructions that specify which red-flag symptoms to watch for (worsening chest pain, new breathlessness, sweating, nausea), how quickly to return, and what to do if symptoms recur outside working hours. NHS Resolution in England identified failures in safety netting as one of the top findings across 220 emergency department negligence claims. NHS Resolution ED review (2025). The same principle applies under Irish law: if you were discharged from an Irish A&E without written return instructions, and you later suffered avoidable harm because you didn't know when to come back, the absence of that instruction is itself a provable breach, separate from the initial diagnostic error.
From handling cardiac negligence cases in Irish courts, the timestamp audit is the strongest evidence. Every ECG printout carries an automatic timestamp. Every blood draw is logged. Every discharge is documented. When those timestamps are laid against the HSE's protocol targets, the breach either appears or it doesn't. The expert's job is to interpret what the gap between the target and the actual timing meant for the patient's heart.
Loss of chance: when the hospital says "it was already too late"
The most common defence in cardiac negligence claims in Ireland is the "inevitability" argument: the heart attack was so severe that the outcome would have been the same regardless of the delay. The Supreme Court addressed this directly in Philp v Ryan [2004] IESC 105.
In Philp, Mr David Philp's prostate cancer diagnosis was delayed by eight months due to negligence at the Bon Secours Hospital in Cork. The hospital argued that earlier treatment wouldn't have changed the prognosis. The Supreme Court disagreed. Fennelly J held that a patient can be compensated for the loss of an opportunity to receive timely treatment, even when the treatment's success was not guaranteed. The Court increased damages from €45,000 to €100,000, including €50,000 in aggravated damages after it emerged that the defendant had falsified clinical notes, as reported in the Supreme Court judgment.
Chief Justice Clarke later confirmed this approach in Morrissey v HSE [2020] IESC 6, stating that the "loss of chance" framework from Philp represents the correct approach in appropriate cases.
For cardiac claims, Philp is directly relevant. If a delayed ECG or missed Troponin test meant you lost the window for timely PCI, you may have lost the chance to save more heart muscle. A consultant cardiologist can quantify this: the difference between the heart damage you now have and the damage you would likely have sustained with timely treatment. That difference is the compensable injury, even if the heart attack itself was always going to happen.
Date of knowledge: when the clock really starts for cardiac claims
The limitation period for heart attack negligence claims in Ireland is two years from the "date of knowledge" under the Civil Liability and Courts Act 2004, s.2. For cardiac cases, this date isn't always obvious. Unlike in England and Wales, where the limitation period for personal injury is three years under the Limitation Act 1980, Irish law applies a strict two-year window, making early legal advice on the "date of knowledge" calculation particularly important.
A patient may survive a missed heart attack and feel relatively stable for months or years. Then an echocardiogram reveals permanent myocardial scarring, reduced ejection fraction, or the onset of heart failure. The injury (the permanent cardiac damage) only becomes known when it's diagnosed, not when the original misdiagnosis occurred. If you attended A&E in January 2024 with chest pain, were sent home with antacids, and only discovered in September 2025 that you'd suffered a heart attack with lasting damage, the two-year clock may run from September 2025.
What the timeline estimates don't account for: the "date of knowledge" also requires that you knew (or ought reasonably to have known) that the damage was attributable to negligence. If nobody told you the original A&E visit was a missed diagnosis, the clock may not start until you have reason to connect the two events. Consult a solicitor experienced in medical negligence time limits to assess when your clock started.
The Patient Safety (Notification) Act 2023 introduced mandatory open disclosure for certain patient safety incidents in Ireland. Healthcare providers are now required to notify patients (or their families) when a notifiable incident has occurred. For cardiac patients, this could be the mechanism by which you first learn that your heart attack was mismanaged: a formal letter from the hospital explaining that a patient safety incident took place during your care. That notification may itself become the trigger for the "date of knowledge" and the start of the two-year limitation clock. Keep any such letter and seek legal advice immediately.
There is a gap between when an incident happens and when the hospital even reports it internally. The SCA's analysis of the National Incident Management System (NIMS) found that the average time for a healthcare facility to report a diagnostic incident was 57 days. That means a diagnostic error during your A&E visit may not be flagged in the hospital's own system for nearly two months. If you request your records promptly under the Data Protection Act 2018, you may identify the error before the hospital itself has formally acknowledged it.
Compensation for heart attack negligence (2026)
Compensation for heart attack misdiagnosis in Ireland follows the Judicial Council Personal Injuries Guidelines (2021). The same brackets apply to cardiac negligence as to any personal injury. Awards depend on the severity of the cardiac damage, its impact on daily life, and the quality of medical evidence.
| Severity | Description | General damages range |
|---|---|---|
| Most severe | Serious heart damage with reduced life expectancy and permanent disability (e.g., severe heart failure, NYHA Class III/IV) | €150,000 to €210,000 |
| Severe | Permanent damage limiting work and daily life but not necessarily life expectancy (e.g., chronic angina requiring lifestyle modification) | €90,000 to €175,000 |
| Moderate | Some permanent damage, effectively controlled by medication, largely normal life | €30,000 to €90,000 |
| Minor | Short-term recovery with no permanent damage (e.g., temporary distress from missed diagnosis, full recovery after treatment) | €3,000 to €25,000 |
Source: Judicial Council Personal Injuries Guidelines (2021). Ranges are for general damages only. Every case turns on its own facts.
General damages cover pain, suffering, and loss of amenity. Special damages are calculated separately and are uncapped. For cardiac patients, special damages include the cost of lifelong medication (statins, beta-blockers, ACE inhibitors, antiplatelet drugs), cardiac rehabilitation programmes, future cardiology consultations, reduced earning capacity, and home adaptations if physical capacity is permanently limited.
One detail that surprises clients: psychological injury is a separate compensable head of damage. Cardiac neurosis (persistent fear of another heart attack) and post-traumatic stress disorder following a near-death experience in an Irish hospital are recognised under the Guidelines. The compensation spoke on this site covers how general and special damages interact.
Which route applies to you?
| Scenario | Likely breach | Key evidence |
|---|---|---|
| Sent home from A&E, later diagnosed with heart attack | Premature discharge. Incomplete Troponin protocol. ECG delay or misread. | A&E records, ECG timestamps, Troponin results, discharge notes, re-admission records |
| GP dismissed symptoms as indigestion or stress | Failure to refer. No ECG ordered. No cardiac workup before assuming non-cardiac cause. | GP records, referral (or lack of), subsequent hospital records |
| Transferred between hospitals with delay | Breach of 30-minute DIDO and 90-minute transfer targets. | Ambulance records, transfer logs, PCI centre admission time |
| Atypical symptoms (especially women) labelled as anxiety/menopause | Diagnostic overshadowing. Failure to perform cardiac testing before psychiatric/hormonal label. | Triage notes, presenting symptoms, tests ordered (or not), clinical reasoning documented |
| Heart failure diagnosed months/years after original event | Delayed consequence of missed acute event. "Date of knowledge" likely starts at heart failure diagnosis. | Original A&E records, echocardiogram showing scarring, cardiologist linking damage to missed event |
Steps to take now
Estimated effort: 1-2 hours for initial steps. What you need: hospital records, GP records, medication list, timeline of symptoms and treatment.
- Request your medical records. Write to the hospital's Medical Records Department and your GP. Under the Data Protection Act 2018, you're entitled to copies. For cardiac claims, request these specific records from each source. From your GP: clinical notes covering the weeks before and after the event, referral letters, and blood test results. From the National Ambulance Service: the Patient Report Form (PRF) including response times and any ECG readings taken in the ambulance. From the hospital: the A&E triage record, all ECG printouts (which carry automatic timestamps), serial Troponin results with draw times, nursing observation charts, the discharge summary, and any internal incident reports. From the PCI centre (if you were transferred): the catheterisation lab record showing arrival time, procedure start, and angiographic findings. Request from each source separately, because Ireland has no national electronic health record linking them. How to access your records
- Note the timeline. Record when symptoms started, when you arrived at hospital, what tests were done, when you were discharged, and when the correct diagnosis was made. Timestamps are central to cardiac claims.
- Keep all correspondence. Appointment letters, referral confirmations, discharge summaries, medication lists, and cardiac rehabilitation records all form part of the evidence base.
- Consult a solicitor experienced in cardiac claims. An independent cardiologist's report is needed to prove breach, causation, and the extent of damage. Your solicitor will commission this. Free initial review
- Check your timeline. The two-year clock runs from the "date of knowledge." If you only recently discovered the connection between your A&E visit and your current heart condition, you may still be within time. Time limits explained
Common Questions
Can I claim if the hospital delayed my ECG beyond 10 minutes?
Yes, if the delay caused additional heart damage. The HSE's ACS Programme requires ECG within 10 minutes. The NOCA 2024 audit found only 35% of PCI centres met this target.
A delayed ECG can delay diagnosis and treatment. The expert cardiologist measures additional myocardial damage caused by the gap. NOCA data supports the claim of systemic failure.
Why it matters: Protocol breach plus documented damage equals the foundation of a claim.
Next step: NOCA Irish Heart Attack Audit 2024 • How to prove negligence
Was I discharged too early if only one Troponin test was done?
A single negative Troponin test does not rule out a heart attack. Troponin levels rise over hours, and serial testing (at 0, 3, and 6 hours) is the recognised standard. Discharging you after one test may be a breach of the protocol.
Serial Troponin measures the "delta" (change over time). A normal first test can precede a positive second or third test. The timestamps in your records show whether the protocol was completed.
Why it matters: This is one of the most common and most provable patterns of cardiac negligence.
Next step: Expert report requirements • Access your records
Are women more likely to be misdiagnosed with a heart attack?
Yes. Women present with atypical symptoms more often than men, and research confirms they're more likely to be initially misdiagnosed. A 2025 Croí survey of 502 Irish women found only 3% could name all heart attack symptoms correctly.
Atypical symptoms include jaw, neck, back pain, nausea, and fatigue. One in two Irish women were unaware symptoms differ from men's. Women wait an average of 37 minutes longer to seek help.
Why it matters: Diagnostic overshadowing based on gender or age is a breach of the standard of care.

What is the time limit for a heart attack claim in Ireland?
Two years from the "date of knowledge" under the Civil Liability and Courts Act 2004. For cardiac cases, this may be the date you discovered the permanent damage (e.g., heart failure), not the date of the original missed event.
Late-onset heart failure can shift the date of knowledge forward. You must also have known (or ought to have known) the damage was linked to negligence. Claims for children don't start running until they turn 18.
Why it matters: Many people wrongly believe they're time-barred when the clock hasn't started yet.
Next step: Civil Liability Act 2004, s.2 • Time limits explained
How much compensation for heart attack misdiagnosis in Ireland?
The Judicial Council Guidelines (2021) set general damages for heart injury at €150,000 to €210,000 for the most severe cases. Special damages (medication, rehabilitation, lost earnings, future care) are calculated separately and have no cap.
Severe: €90,000 to €175,000. Moderate: €30,000 to €90,000. Lifelong cardiac medication costs are a specific special damage. Psychological injury (cardiac neurosis, PTSD) is a separate head.
Why it matters: Total awards in serious cardiac cases can significantly exceed the general damages bracket alone.
Next step: Judicial Council Guidelines (2021) • Compensation guide
Can I claim even if the heart attack would have happened regardless?
Yes, in appropriate cases. The Supreme Court in Philp v Ryan [2004] established that a patient can be compensated for the "loss of chance" of a better outcome, even when full recovery was never guaranteed. The Court awarded €100,000 including aggravated damages.
Loss of chance applies where delayed treatment caused additional damage. A cardiologist quantifies the difference between actual and expected damage. Clarke CJ confirmed this approach in Morrissey v HSE [2020].
Why it matters: The "it was inevitable" defence can be overcome with proper expert evidence.
Next step: Philp v Ryan [2004] IESC 105 • Expert report requirements
Can I claim against my GP for not referring me to hospital?
Yes, if the GP failed to recognise symptoms that should have triggered an urgent hospital referral. A GP who attributes cardiac symptoms to indigestion or stress without ordering an ECG or referring for cardiac workup may have breached the standard of care.
Both the GP and the hospital can be concurrent wrongdoers under the Civil Liability Act 1961, s.11. Your claim can proceed against both. GP records will show what was reported, examined, and decided.
Why it matters: The chain of negligence frequently starts before the hospital.
Next step: GP negligence • Free initial review
Do I need a cardiologist or a GP to write my expert report?
A consultant cardiologist, not a GP. Irish courts require an expert of equal specialisation to the defendant. Only a cardiologist can scientifically prove that heart muscle death became irreversible after the negligent delay, meeting the rigorous "but for" causation test set by the Supreme Court.
The cardiologist reviews ECG traces, Troponin timestamps, and imaging. They measure actual damage against the expected outcome with timely care. A GP report will not satisfy the court on complex cardiac causation.
Why it matters: Cases with GP-only reports are more likely to fail on causation.

Can I claim for anxiety or PTSD after a missed heart attack?
Yes. Cardiac neurosis and PTSD are recognised psychiatric conditions compensable under the Personal Injuries Guidelines. Fear of a recurrent heart attack, sleep disturbance, and avoidance behaviours following a near-death experience in hospital are common and compensable.
Psychological injury is assessed separately from cardiac damage. A psychiatric report is usually needed to support this head of claim. Both the physical and psychological injuries are claimed together.
Why it matters: Many clients don't realise the mental health impact is separately compensable.

Can I claim for ambulance delays that worsened a heart attack?
Potentially, although pre-hospital claims are complex. The National Ambulance Service's PURPLE call response time averaged 24 minutes across the Republic in 2025, against an 18-minute-59-second target. If an ambulance delay resulted in you missing the treatment window, and additional heart damage resulted, this forms part of the overall case. The HSE is the defendant for both the ambulance service and the public hospital.
Ambulance response logs document arrival times. Pre-hospital ECG by ambulance staff is part of the protocol. 55% of patients arrived by ambulance in the NOCA 2024 data. Hospital handover delays (ambulances stuck at A&E) can compound the problem by removing vehicles from the community, as reported by the Irish News (Jan 2026).
Why it matters: The claim examines the full chain from first call to treatment.

Can my family claim if a loved one died from a missed heart attack?
Yes. Under Part IV of the Civil Liability Act 1961, dependants of a person who died due to negligence can bring a wrongful death claim. Heads of damage include solemn damages for grief, dependency (financial support the deceased would have provided), mental distress, funeral costs, and the deceased's own pain and suffering between the negligent act and death.
A spouse, partner, parent, or child may all qualify as dependants. The claim is brought by the personal representative of the deceased's estate. The same evidence applies: hospital records, Troponin results, ECG timestamps, and a cardiologist's report linking the death to the diagnostic delay. Fatal cardiac claims are among the highest-value medical negligence cases in Ireland.
Why it matters: Families often don't know they have a separate legal right to claim.
