why heart attack comes

A heart attack occurs primarily because the blood supply to the heart is suddenly interrupted. This interruption is often caused by a blockage in one or more of the coronary arteries, which supply blood and oxygen to the heart muscle. The blockage is usually due to a buildup of fatty deposits called plaques in the arteries, a condition known as coronary heart disease (CHD). When a plaque ruptures, a blood clot forms and can block blood flow to the heart, causing damage or death to the heart muscle tissue.

Additional risk factors that increase the likelihood of a heart attack include smoking, high blood pressure, high cholesterol, diabetes, obesity, lack of physical activity, unhealthy diet, stress, and a family history of heart disease.

In less common cases, a heart attack may result from a severe spasm of a coronary artery or from a lack of oxygen in the blood due to lung-related issues. Prompt treatment is critical to prevent permanent heart damage or death.
