A heart attack occurs when the blood supply to the heart is blocked, causing damage to the heart muscle. It’s a serious medical emergency that requires immediate attention.

According to the American Heart Association, someone in the United States has a heart attack every 40 seconds. So, recognizing the warning signs of a heart attack is essential to ensure prompt treatment and prevent further damage to the heart.

Chest Pain

Chest pain is the most common symptom of a heart attack. The pain may feel like pressure, squeezing, fullness, or pain that lasts for more than a few minutes or goes away and comes back.

The pain may also spread to the arms, shoulders, back, neck, jaw, or stomach.

Shortness of Breath

Shortness of breath is another common symptom of a heart attack. It may occur before chest pain or without chest pain. You may feel like you can’t catch your breath or like you are suffocating. You may also feel dizzy, lightheaded, or nauseous.

Cold Sweats

Cold sweats that are not associated with exercise or activity may be a warning sign of a heart attack. These sweats may occur suddenly and may feel like a clammy, cool feeling on the skin.

Fatigue

Fatigue may be a warning sign of a heart attack, especially in women. It may occur days or weeks before the actual attack. You may feel tired and lack energy even with minimal exertion.

Feeling of Indigestion

A feeling of indigestion or a stomachache that does not improve with antacids may be a warning sign of a heart attack. This symptom is more common in women than in men.

Nausea and Vomiting

Nausea and vomiting may occur during a heart attack, especially in women. These symptoms may be accompanied by pain, shortness of breath, and sweating.

Unexplained Anxiety

Unexplained anxiety or a feeling of impending doom may be a warning sign of a heart attack. You may feel like something bad is going to happen or like you are experiencing a panic attack.

Weakness

Weakness or feeling faint may occur during a heart attack. You may feel like you are going to pass out or lose consciousness.

Irregular Heartbeat

An irregular or racing heart may be a warning sign of a heart attack. Your heartbeat may feel faster or slower than normal, and it may be irregular or skipping beats.

Sudden Onset of Symptoms

The symptoms of a heart attack may come on suddenly and may be severe. If you experience any of these symptoms, call 911 or your local emergency medical services immediately.
