What is heart disease?

Heart disease – also called cardiovascular disease and coronary heart disease – is a simple term used to describe several problems related to plaque buildup in the walls of the arteries, or atherosclerosis. As the plaque builds up, the arteries narrow, making it more difficult for blood to flow and creating a risk for heart attack or stroke.

Other types of heart disease include heart failure, an irregular heartbeat – or arrhythmia – and heart valve problems. To learn more about heart disease and conditions that can lead to heart disease, heart attack or stroke, browse any of the conditions below.
