Heart Attack

Heart Attack is a serious medical condition where the blood supply to the heart is suddenly blocked, usually by a blood clot. This can cause damage to the heart muscle and is a medical emergency.

Causes

A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies. The most common cause of heart attacks is coronary artery disease (CAD), a condition in which the major blood vessels that supply the heart with blood, oxygen and nutrients (coronary arteries) become clogged with fatty deposits called plaques.

Symptoms

Symptoms of a heart attack can vary from person to person. They may start slowly and involve mild pain or discomfort, or they may be sudden and intense. The most common symptoms include:

• Chest pain or discomfort
• Shortness of breath
• Nausea, lightheadedness, or cold sweats

Treatment

Treatment for a heart attack usually involves taking medications to break up the clot and prevent further clots from forming. In some cases, surgery may be required to restore blood flow to the heart. The sooner treatment is started, the better the chances of survival and recovery.

Prevention

Prevention of heart attacks involves managing risk factors and leading a healthy lifestyle. This includes eating a healthy diet, regular exercise, not smoking, and controlling conditions such as high blood pressure, diabetes, and high cholesterol.
