Trial-Ready Heart Attack Misdiagnosis Law Firm in Florida
Heart disease is the leading cause of death in the United States, and every minute of delay in treating a heart attack destroys more heart muscle. Emergency medicine has a phrase that says it plainly: time is muscle. When a patient walks into an emergency room with symptoms of a myocardial infarction and is sent home with a diagnosis of acid reflux, anxiety, or musculoskeletal pain, the consequences can be catastrophic, causing permanent heart damage, heart failure, or death.
Freedland Harwin Valori Gander represents patients and families throughout Florida who suffered serious harm, permanent cardiac damage, heart failure, or the loss of a loved one because a physician failed to recognize and treat a heart attack in time. We bring the medical knowledge and legal firepower to hold those responsible accountable.

What Happens During a Heart Attack and Why Time Matters
A heart attack, medically known as a myocardial infarction (MI), occurs when blood flow to a section of the heart muscle is blocked, typically by a blood clot forming at the site of a ruptured coronary artery plaque. Without blood flow, heart muscle cells begin to die. The longer the blockage persists, the more heart muscle is lost. Once cardiac muscle dies, it does not regenerate.
The treatment for a STEMI (ST-elevation myocardial infarction), the most severe type, is percutaneous coronary intervention (PCI), commonly called an angioplasty. It must be performed within 90 minutes of hospital arrival to meet the standard of care. For NSTEMIs and unstable angina, the timeline is somewhat more flexible but still demands urgent evaluation and management.
When an ER physician fails to recognize a heart attack, delays the workup, or discharges a patient who is actively infarcting, the patient may leave the hospital with damage that could have been minimized or die from a condition that was eminently treatable.
Why Heart Attacks Are Misdiagnosed: Common Physician Failures
Despite decades of advances in cardiac care, heart attacks continue to be misdiagnosed at an alarming rate. Several patterns of physician error contribute to this problem:
- Atypical presentations, particularly in women: While the classic heart attack symptom is crushing chest pain radiating to the left arm, many patients, especially women, diabetics, and elderly patients, present with nausea, fatigue, jaw pain, shortness of breath, or back pain. Physicians who fail to recognize atypical presentations miss heart attacks at a disproportionate rate in these groups.
- Misreading or dismissing the ECG: An ECG is the first and most critical tool for identifying a STEMI. Misinterpreting ST-segment changes, failing to compare to prior ECGs, or missing subtle findings is a common source of negligence.
- Failure to obtain serial troponins: A single normal troponin does not rule out a heart attack. The standard of care requires serial troponin testing over several hours to detect a rising level that indicates cardiac damage. Skipping this step and discharging the patient prematurely is a recognized form of negligence.
- Anchoring on a benign diagnosis: Physicians who attribute chest pain to acid reflux, panic attacks, or musculoskeletal strain without ruling out cardiac causes may fail to pursue the workup that would have revealed the true diagnosis.
- Failing to consider cardiac risk factors: A patient with hypertension, diabetes, high cholesterol, obesity, a smoking history, or a family history of heart disease deserves a higher index of suspicion and a more thorough workup than a low-risk patient with similar symptoms.
- Premature discharge: Sending a patient home before the cardiac workup is complete, or before a period of observation has confirmed stability, is one of the most consequential and most litigated errors in emergency medicine.
- Failure to consult cardiology: When the diagnosis is uncertain or the patient’s condition is deteriorating, the standard of care may require a cardiology consultation. Failing to make that call in a timely manner can cost the patient critical hours.

Heart Attack Misdiagnosis in Women: A Specific and Serious Problem
Research has consistently shown that women are more likely to have their heart attack symptoms dismissed, misdiagnosed, or attributed to anxiety or non-cardiac causes than men. Women more frequently experience atypical symptoms, including nausea, fatigue, shortness of breath, and upper back pain, that do not fit the textbook presentation emergency physicians are trained to recognize.
This disparity has real consequences. Studies show that women under 55 who have heart attacks are more likely to die in the hospital than men of the same age, in part because of diagnostic delays. When a physician fails to pursue an adequate cardiac workup in a woman presenting with possible cardiac symptoms, attributing them to stress or gastrointestinal problems without ruling out MI, and that woman suffers a heart attack or dies, the failure may constitute actionable negligence.
FHV Legal has represented women whose heart attacks were dismissed for hours or days, causing preventable cardiac damage. We take these cases seriously, and we know how to present them compellingly to a jury.
Injuries and Outcomes from a Missed Heart Attack Diagnosis
The harm from a missed or delayed heart attack diagnosis ranges from significant to fatal. Patients who survive may face:
- Permanent loss of cardiac function, with areas of the heart muscle that no longer contract effectively
- Congestive heart failure, a chronic condition requiring lifelong medication, lifestyle restrictions, and ongoing monitoring
- Cardiogenic shock, when the heart can no longer pump enough blood to maintain adequate organ perfusion
- Cardiac arrhythmias, including ventricular fibrillation, which can cause sudden cardiac death
- The need for implanted devices, such as defibrillators or pacemakers, due to damage to the heart’s conduction system
- A significantly reduced quality of life and the inability to return to prior work or daily activities
- Death, which may occur in the hospital, at home after discharge, or suddenly and without warning due to a fatal arrhythmia
In wrongful death cases, Florida’s Wrongful Death Act allows surviving spouses, children, and parents to seek compensation for medical expenses, funeral costs, lost financial support, and the grief of losing a family member to a preventable medical failure.
Florida Hospitals and Heart Attack Malpractice Accountability
Florida’s major hospital systems, including Jackson Memorial Hospital in Miami, Broward Health Medical Center in Fort Lauderdale, and Cleveland Clinic Weston, operate cardiac care centers with the personnel and technology to diagnose and treat myocardial infarctions promptly and effectively. When their emergency departments fall short of that standard, the institution bears responsibility alongside the individual physician.
FHV Legal has taken on Florida’s largest hospital systems and their defense teams. We know how these institutions investigate and sometimes minimize claims of heart attack misdiagnosis, and we know how to build cases that cut through those defenses.
Frequently Asked Questions About Failure to Diagnose a Heart Attack
How do I know if my heart attack was misdiagnosed due to negligence?
Key indicators include: you went to an ER with chest pain, shortness of breath, or other cardiac symptoms and were discharged without a complete workup; your ECG findings were misread or not followed up on; you were not given serial troponin tests; you were sent home and suffered a major cardiac event shortly after; or you were told your symptoms were anxiety, acid reflux, or musculoskeletal in nature without cardiac causes being ruled out. A free case evaluation by FHV Legal can determine whether negligence played a role.
What if my ECG was normal? Can there still be malpractice?
Yes. A normal ECG does not rule out a heart attack, particularly in the early hours of symptom onset or in cases of NSTEMI or unstable angina. The standard of care requires serial ECGs and serial troponin testing, along with clinical assessment of risk factors and symptom history. A physician who relies on a single normal ECG to discharge a symptomatic patient without further evaluation may have acted negligently.
How long do I have to file a heart attack misdiagnosis claim in Florida?
Florida’s medical malpractice statute of limitations is generally two years from when you knew or should have known the negligence caused harm, with an absolute four-year limit in most cases. In wrongful death cases, the two-year period typically begins from the date of death. Because pre-suit investigation takes additional time, contacting an attorney as early as possible is strongly advisable.
Can the hospital be held liable for an ER doctor's failure to diagnose my heart attack?
In many cases, yes. If the ER physician was a hospital employee, the hospital is directly liable for their negligence. Even when the physician is an independent contractor, the hospital may still be liable under the doctrine of apparent agency, particularly when the patient had no meaningful choice of physician. Our attorneys conduct a thorough liability analysis in every case to identify all responsible parties.
