A heart attack misdiagnosis claim arises when a patient having a myocardial infarction, or unstable angina signaling one, is diagnosed with a less serious problem such as acid reflux, a panic attack or a pulled muscle, and the delay in treatment lets more heart muscle die. In Virginia, it is a medical malpractice claim, judged by what a reasonably prudent provider would have done with the same symptoms and test results.
Blank Kim Injury Law reviews these cases for patients and families across Northern Virginia from our office in Fairfax. We go through the ECG tracings, lab times and discharge paperwork with physicians in emergency medicine and cardiology. Consultations are available in English, Korean and Spanish.
The standard chest pain workup
Chest pain is one of the most common reasons adults go to an emergency department, and most of it is not cardiac. Because a heart attack cannot be excluded by how a patient looks, emergency medicine uses a structured approach:
- An electrocardiogram (ECG) quickly after arrival, with national guidance calling for it within about 10 minutes, compared with any prior ECG.
- Troponin blood tests, repeated over a set interval. A single early troponin can be normal in a heart attack that has just begun.
- A risk score, such as the HEART score, that combines history, ECG, age, risk factors and troponin.
- For patients who are not low risk, observation, stress testing, CT imaging of the coronary arteries or a cardiology consultation.
- Consideration of other dangerous causes of chest pain, including aortic dissection and pulmonary embolism.
- Clear discharge instructions about which symptoms require an immediate return.
Missed heart attacks usually trace to a step skipped or a result misread: an ECG not repeated when pain returned, a second troponin never drawn, or a risk score applied to the wrong patient.
Who gets missed: atypical heart attack symptoms
The textbook picture is crushing chest pressure spreading to the left arm. Many patients never have it. Women, people with diabetes, older adults and people with kidney disease often present with:
- Shortness of breath without chest pain
- Nausea, vomiting or a feeling of indigestion
- Pain in the jaw, neck, back, shoulder or upper abdomen
- Sudden fatigue or weakness
- Cold sweats or lightheadedness
Younger adults are also missed, particularly those with a strong family history, high cholesterol or recent stimulant use. A careful provider weighs these risk factors rather than relying on age alone.
What heart attacks are mistaken for
| Diagnosis given | Why it gets chosen | What should have prompted more testing |
|---|---|---|
| Acid reflux or indigestion | Burning or upper abdominal discomfort, relief after an antacid | Symptoms with exertion, cardiac risk factors, an abnormal or changing ECG |
| Anxiety or panic attack | A racing heart, a history of anxiety, a young or stressed patient | Persistent symptoms, abnormal vital signs, no repeat troponin |
| Chest wall or muscle strain | Tenderness when the chest is pressed | Tenderness does not exclude a heart attack; risk factors still require testing |
| Gallbladder problems | Upper right abdominal pain and nausea | Pain not explained by imaging, sweating, ECG changes |
| Viral illness | Fatigue, aches, shortness of breath | Shortness of breath with exertion in an older or diabetic patient |
When a condition is mislabeled like this, the case shares features with other misdiagnosis claims, but the time pressure is far greater.
ECG and troponin errors
The ECG and the troponin test are where many missed heart attacks can be proven, because both leave a permanent record. Errors we look for include:
- Relying on the machine’s automated reading instead of a physician’s interpretation
- Missing ECG patterns that signal a blocked artery without classic ST elevation, such as a posterior heart attack or patterns known as Wellens and de Winter
- Not repeating the ECG when symptoms changed or returned
- Drawing only one troponin, or drawing the second too early to be meaningful
- Treating a small rise in troponin as insignificant without explaining it
- Discharging the patient before a pending troponin result came back, with no one assigned to follow it up
How delay damages the heart
Cardiologists say “time is muscle.” Once a coronary artery is blocked, the heart muscle it feeds starts to die, and the damage grows until blood flow is restored. For the most serious type of heart attack, known as a STEMI, national quality targets call for opening the artery with a catheter procedure within 90 minutes of first medical contact at a hospital that performs it.
Delay can lead to:
- Heart failure from a weakened heart that no longer pumps well
- Dangerous heart rhythms and sudden cardiac arrest
- The need for an implanted defibrillator, bypass surgery or a heart transplant evaluation
- Brain injury after a cardiac arrest
- Loss of the ability to work, exercise and live independently
When a missed heart attack is fatal, the family’s claim is explained on our malpractice wrongful death page.
Evidence in a missed heart attack case
We request the ECG tracings themselves, not only the typed interpretation, along with the time each was taken. We also collect the troponin values with their draw and result times, the vital signs, triage notes, any risk score documentation, the discharge instructions, and the ambulance run report, since many paramedics perform a 12-lead ECG before arrival.
Later records matter too. A cardiac catheterization report, echocardiogram or autopsy can show how old the blockage was and how much muscle was lost, which helps a cardiologist explain what earlier treatment would have saved. Records from an urgent care center or a telehealth visit in the days before the heart attack are often part of the picture as well.
Missed heart attack claims under Virginia law
Chest pain patients in Northern Virginia are seen in hospital emergency departments, urgent care centers along Route 50 and Route 7, primary care offices and virtual visits. In every setting, Virginia measures care against a statewide standard under Va. Code § 8.01-581.20.
- A written opinion from a qualified expert witness must support the claim before suit is served, under Va. Code § 8.01-20.1.
- Suit generally must be filed within two years of the malpractice, under Va. Code § 8.01-243(A).
- Total damages are capped by Va. Code § 8.01-581.15.
Providers sometimes argue the patient declined admission or left against medical advice. What the patient was actually told about the risks, and how it was documented, often decides whether that argument has any weight. Our guide to Virginia medical malpractice laws explains the rules in more detail.
