Short answer: A missed heart attack can be medical malpractice in New York when a doctor, nurse or hospital failed to order or read basic tests such as an ECG and troponin, sent a patient home with clear warning signs, or delayed treatment, and that delay caused heart damage or death. Most New York claims must be filed within 2 years and 6 months of the error.
This is general information, not legal or medical advice. If you have chest pain or other heart attack symptoms now, call 911. Speak with your doctor and a lawyer licensed in your state about your situation.
Every minute counts during a heart attack, because blocked blood flow damages heart muscle over time. When symptoms are dismissed as anxiety, heartburn or a pulled muscle, a patient can lose the window for treatment that limits the damage. This guide explains how heart attacks get missed, when a missed diagnosis may be malpractice, what evidence matters, and the filing deadlines in New York and nearby states.
Why are heart attacks sometimes missed?
The National Heart, Lung, and Blood Institute notes that heart attack symptoms can start slowly, come and go, and differ between men and women. Besides chest pain, they can include pain in the arm, back, jaw or upper belly, shortness of breath, sweating, nausea, dizziness and unusual tiredness. Some heart attacks cause almost no symptoms, especially in older adults and people with diabetes.
Common reasons a heart attack is missed include:
- Symptoms labeled as something else: indigestion, a panic attack, a muscle strain or a stomach virus.
- No ECG, or an ECG read too late: or changes on the tracing that were not compared with an earlier one.
- Troponin not ordered or not repeated: a single normal blood test early on does not always rule out a heart attack.
- Bias about who has heart attacks: younger patients and women are more often sent home with a different explanation.
When is a missed heart attack considered malpractice?
Some heart attacks are hard to spot. A malpractice claim generally needs two things:
- A departure from accepted practice. A qualified physician, often an emergency medicine doctor or cardiologist, must explain what a reasonably careful provider would have done differently, such as ordering an ECG promptly, repeating troponin tests or admitting the patient for observation.
- Causation and harm. The delay must have made the outcome worse, for example more heart muscle damage, heart failure, cardiac arrest or death, compared with timely treatment.
Experts often point to national guidance. The American Heart Association and American College of Cardiology 2021 guideline for evaluating chest pain recommends that patients with acute chest pain get an ECG reviewed within 10 minutes of arriving, and it explains how high-sensitivity troponin testing should be used to decide who can safely go home.
Who can be responsible for a missed heart attack?
- Emergency room doctors and physician assistants: for not ordering or not acting on tests, or discharging a patient too soon.
- Triage nurses: for assigning a low priority to someone with warning signs.
- Primary care doctors and urgent care clinics: for treating symptoms over the phone or in the office without sending the patient for emergency testing.
- Hospitals: for staffing, protocols and systems that lose or delay results.
Claims against New York City public hospitals have a much shorter notice deadline. See our guide to notice of claim rules for NYC public hospitals, and our guide to emergency room negligence in New York.
What evidence helps in a missed heart attack claim?
- Emergency department records, including triage notes, vital signs and the time each test was ordered and resulted.
- ECG tracings, not just the computer reading, plus any earlier ECGs for comparison.
- Lab results showing troponin values and their times.
- Discharge papers and instructions, including the diagnosis you were given.
- Later records from the hospital where the heart attack was found.

What are the deadlines in New York, New Jersey, Pennsylvania and Connecticut?
These summaries are starting points; public hospitals and children’s claims can follow different rules.
New York
- Filing deadline: generally 2 years and 6 months from the malpractice or the end of continuous treatment under CPLR 214-a. A single emergency room visit usually does not count as continuous treatment.
- Discovery rule: only for missed cancer or a malignant tumor (Lavern’s Law), capped at 7 years from the act, and for foreign objects (1 year from discovery). A missed heart attack usually runs from the date of the error.
- Certificate of merit: CPLR 3012-a generally requires the lawyer to certify that a physician reviewed the case and found a reasonable basis for it.
- Wrongful death: generally 2 years from death under EPTL 5-4.1. The Grieving Families Act was vetoed in December 2025, and the 2026 version did not pass.
New Jersey
- Filing deadline: generally 2 years under N.J.S.A. 2A:14-2.
- Discovery rule: yes, until you knew or reasonably should have known of the injury and that someone may be at fault.
- Affidavit of merit: under N.J.S.A. 2A:53A-27, due within 60 days after the defendant’s answer, with one possible 60-day extension.
- Wrongful death: generally 2 years from death under N.J.S.A. 2A:31-3.
Pennsylvania
- Filing deadline: generally 2 years under 42 Pa.C.S. § 5524.
- Discovery rule: yes, but the MCARE Act sets a 7-year outer limit from the act for most adult claims.
- Certificate of merit: under Pa.R.C.P. 1042.3, filed with the complaint or within 60 days after it.
- Wrongful death: under the MCARE Act, generally 2 years from death.
Connecticut
- Filing deadline: under C.G.S. § 52-584, 2 years from when the injury was sustained or discovered, but no more than 3 years from the act.
- Discovery rule: built in, capped by the 3-year limit; a 90-day extension is available by petition.
- Certificate of good faith: under C.G.S. § 52-190a, filed with a written opinion from a similar health care provider.
- Wrongful death: under C.G.S. § 52-555, generally 2 years from death and no more than 5 years from the act.
How do you find a lawyer for a missed heart attack case?
Look for a firm that regularly handles diagnosis-error cases, works with emergency medicine and cardiology experts, and is licensed where the care happened. Reading how a firm explains failure-to-diagnose claims at Kramer, Dillof, Livingston & Moore can help you understand what these cases involve. You can compare firms in the Top Lawyers category and on the New York location page, including the Kramer, Dillof, Livingston & Moore profile. No lawyer can guarantee a result.
Outcome: get the records, then get answers
Focus on recovery first. Then request the full ER and hospital records, write down your timeline while it is fresh, note your state’s deadline, and have a qualified lawyer and physician review whether the missed diagnosis was reasonable or care fell short.
FAQs
Can you sue an ER for missing a heart attack in New York?
Yes, if the care fell below accepted standards and the delay caused real harm, such as added heart damage or death. A qualified physician usually must support the claim.
How long do you have to sue for a missed heart attack in New York?
Generally 2 years and 6 months from the error or the end of continuous treatment. Claims against NYC public hospitals need a notice of claim within 90 days, and wrongful death claims generally have 2 years from death.
Is it malpractice if my first troponin test was normal?
Not by itself. Early tests can be normal. The question is whether the providers followed accepted practice, such as repeating the test and watching for changes, before sending you home.
