Heart Attack
What is a Heart Attack?
A heart attack, also known as a myocardial infarction, occurs when blood flow to a part of the heart is blocked for a long enough time that part of the heart muscle is damaged or dies.
Causes of a Heart Attack
The most common cause of a heart attack is coronary artery disease, where fatty deposits called plaques build up in the coronary arteries, which supply blood to the heart muscle. If a plaque ruptures, a blood clot can form and block the flow of blood to the heart.
Symptoms of a Heart Attack
- Chest pain or discomfort
- Shortness of breath
- Nausea or vomiting
- Weakness or lightheadedness
- Pain or discomfort in other areas of the upper body, such as arms, back, neck, jaw, or stomach
Risk Factors for a Heart Attack
- Smoking
- High blood pressure
- High cholesterol
- Diabetes
- Obesity
- Sedentary lifestyle
Treatment for a Heart Attack
Immediate medical attention is crucial for a heart attack. Treatment may include medications to dissolve blood clots, procedures to open blocked arteries, and lifestyle changes to prevent future heart attacks.
Prevention of Heart Attacks
Preventing a heart attack involves making healthy lifestyle choices, such as eating a balanced diet, exercising regularly, not smoking, managing stress, and controlling conditions like high blood pressure and diabetes.
