Heart and blood vessel disease, also called heart disease, includes numerous problems, many of which are related to 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.

A heart attackoccurs when the blood flow to a part of the heart is blocked by a blood clot. If this clot cuts off the blood flow completely, the part of the heart muscle supplied by that artery begins to die. Most people survive their first heart attack and return to their normal lives, enjoying many more productive years. But having a heart attack...
An ischemic stroke, which is the most common type of stroke, occurs when a blood vessel that feeds the brain gets blocked, usually from a blood clot. When the blood supply to a part of the brain is cut off, some brain cells will begin to die. This can result in the loss of functions controlled by that part of the brain, such as walking or talking. ...

Tachycardia, or a heart rate that’s too fast, refers to a heart rate of more than 100 beats per minute. An ...
When heart valves don’t open enough to allow the blood to flow through as it should, a condition called stenosis results. When the heart valves don’t close properly and thus allow blood to leak through, it’s called regurgitation. If the valve leaflets bulge or prolapse back into the upper chamber, it’s a condition called prolapse. Discover more abo...
