Coronary artery disease (CAD)  The most common cause of heart attacks is CAD, where the coronary arteries that supply blood to the heart become narrowed or blocked by fatty deposits called plaques.

Atherosclerosis Atherosclerosis is the buildup of plaque inside arteries, which can restrict blood flow to the heart and lead to a heart attack.

High blood pressure (hypertension) Consistently elevated  blood pressure can damage blood vessels, making them more prone to narrowing  and clot formation.

High cholesterol levels High levels of LDL cholesterol (the "bad" cholesterol) can contribute to plaque formation in the arteries, increasing the risk of heart attacks.

Smoking  Smoking damages  blood vessels and accelerates the development of atherosclerosis, significantly increasing the risk of heart attack.

Diabetes  People with diabetes are at a higher risk of heart attacks due to the impact of high blood sugar levels on blood vessels.

Obesity Being overweight or obese is associated with various risk factors for heart disease, including diabetes, high blood pressure, and abnormal cholesterol levels.

Sedentary lifestyle Lack of physical activity can lead to obesity and other risk factors for heart disease.

Stress  Chronic stress can contribute to the development of heart disease through various mechanisms, including elevated blood pressure and unhealthy coping behaviors like overeating or smoking.

Family history  A family history of heart disease can increase the risk of having a heart attack, suggesting a genetic predisposition.
