A heart attack, also known as a myocardial infarction, occurs when the blood flow to a part of the heart muscle is blocked, usually by a blood clot. This blockage can lead to damage or death of the heart muscle cells. There are several causes that can lead to a heart attack, including:
Coronary artery disease: This is the most common cause of heart attacks. Coronary artery disease occurs when the blood vessels that supply the heart with blood become narrowed or blocked due to the buildup of fatty deposits (plaques) on their walls.
High blood pressure: If you have high blood pressure, your heart has to work harder to pump blood through your body, which can lead to damage of the blood vessels and increase your risk of a heart attack.
Smoking: Smoking is a major risk factor for heart attacks. The chemicals in cigarette smoke can damage the blood vessels and increase the buildup of plaques on the artery walls.
Diabetes: Diabetes can increase your risk of a heart attack because it can damage the blood vessels and increase your risk of developing coronary artery disease.
Obesity: Being overweight or obese can increase your risk of a heart attack because it can lead to high blood pressure, high cholesterol, and diabetes.
Stress: Chronic stress can increase your risk of a heart attack by raising your blood pressure and increasing your heart rate.
Lack of physical activity: Not getting enough exercise can increase your risk of a heart attack by contributing to high blood pressure, high cholesterol, obesity, and other risk factors
