What are Causes of Cardiovascular disease?
CAD occurs when plaque forms in the arteries that supply the heart with blood. Plaque is made up of fat, cholesterol, calcium, and other substances in the bloodstream. The buildup can restrict bloodflow to the heart. Sometimes a plaque can rupture or burst which can cause a blood clot that completely blocks the artery—this can cause a heart attack or a stroke. If the arteries are damaged by smoking, diabetes, high blood pressure, or high cholesterol this process occurs more readily.
