A heart attack, or myocardial infarction, happens when a blockage restricts blood flow to the heart, cutting off its oxygen supply. A common question people ask is, how long does a heart attack last? The truth is, the duration can vary depending on the severity and how quickly medical intervention is received.
Understanding the warning signs and acting quickly can mean the difference between life and death. At Complete Cardiac and Vascular Care, we are committed to educating our patients about heart health and providing expert cardiac care.
How Long Does a Heart Attack Last?
A heart attack can last anywhere from a few minutes to several hours, depending on the severity and medical intervention. The symptoms might start gradually or suddenly, and they won’t go away until blood flow is restored to the heart.
Here’s a breakdown of how heart attack symptoms can develop:
- Mild or early warning symptoms: Some people experience discomfort in the chest, arms, jaw, or back hours or even days before a major heart attack.
- Acute heart attack symptoms: Once a full heart attack begins, the pain and discomfort typically last 15 minutes or longer.
- Ongoing chest pain: If the blockage remains untreated, chest pain can persist for hours and cause severe damage to the heart muscle.
The key takeaway is that heart attack symptoms don’t go away on their own. Prompt medical care is essential to avoid severe complications or fatal outcomes.
Recognizing the Warning Signs of a Heart Attack
Heart attacks can present with a variety of symptoms, and not everyone experiences them the same way. The most common signs include:
- Chest discomfort or pain, commonly felt as pressure, squeezing, or a sense of fullness.
- Discomfort or pain that may spread to the arms, neck, jaw, back, or stomach.
- Shortness of breath, even without chest pain
- Cold sweat, dizziness, or nausea
- Unusual fatigue, especially in women
Important: Some heart attacks, known as silent heart attacks, may have mild or vague symptoms that are often mistaken for indigestion or fatigue. If you suspect something is wrong, it’s always best to act with caution.
What to Do If You Suspect a Heart Attack
If you or someone else experiences heart attack symptoms, act fast:
- Call 911 immediately. Every second counts. Emergency responders can start treatment on the way to the hospital.
- Chew aspirin (if advised by a doctor). Aspirin helps thin the blood and may improve circulation.
- Stay calm and rest. Avoid physical exertion and try to remain still until help arrives.
- If needed, perform CPR. If the person is unconscious and unresponsive, begin chest compressions until medical professionals arrive.
How to Reduce Your Heart Attack Risk
A heart-healthy lifestyle is key to reducing the risk of a heart attack. Here are key steps to take:
- Maintain a heart-healthy diet by incorporating fruits, vegetables, whole grains, and lean proteins.
- Engage in regular physical activity, aiming for at least 30 minutes most days of the week.
- Reduce stress by practicing relaxation techniques such as meditation or yoga.
- Control blood pressure and cholesterol levels
- Quit smoking and limit alcohol intake
