Cardiac Illness, also called heart disease — includes numerous problems, many of which are related to a process called atherosclerosis. Atherosclerosis is a condition that develops when a substance called plaque builds up in the walls of the arteries. This buildup narrows the arteries, making it harder for blood to flow through. If a blood clot forms, it can stop the blood flow. This can cause a heart attack or stroke.
Who is at risk for cardiac illness ?
There are risk factors that increase the potential to develop plaque within coronary arteries and cause them to narrow. Factors that put people at increased risk for heart disease are- smoking, high blood pressure, high cholesterol, diabetes, obesity etc.
