Atherosclerosis -- hardening and narrowing of the arteries -- gets a lot of bad press but with good reason. This progressive process silently and slowly blocks arteries, putting blood flow at risk.
Atherosclerosis is the usual cause of heart attacks, strokes, and peripheral vascular disease -- what together are called "cardiovascular disease." Cardiovascular disease is the No. 1 killer in America, with more than 800,000 deaths in 2005.
How does atherosclerosis develop? Who gets it, and...
Cardiovascular disease is the leading cause of death for both men and women in the U.S. It is important to learn about your heart to help prevent heart disease. And, if you have heart disease, you can live a healthier, more active life by learning about your disease and treatments and by becoming an active participant in your care.
Coronary Artery Disease
Coronary artery disease (CAD) is atherosclerosis, or hardening, of the arteries that provide vital oxygen and nutrients to the heart.
Abnormal Heart Rhythms
The heart is an amazing organ. It beats in a steady, even rhythm, about 60 to 100 times each minute (that's about 100,000 times each day!). But, sometimes your heart gets out of rhythm. An irregular or abnormal heartbeat is called an arrhythmia. An arrhythmia (also called a dysrhythmia) can involve a change in the rhythm, producing an uneven heartbeat, or a change in the rate, causing a very slow or very fast heartbeat.
The term "heart failure" can be frightening. It does not mean the heart has "failed" or stopped working. It means the heart does not pump as well as it should.
Heart failure is a major health problem in the U.S., affecting nearly 5 million Americans. About 550,000 people are diagnosed with heart failure each year. It is the leading cause of hospitalization in people older than 65.
Heart Valve Disease
Your heart valves lie at the exit of each of your four heart chambers and maintain one-way blood-flow through your heart.
Examples of heart valve disease include mitral valve prolapse, aortic stenosis, and mitral valve insufficiency.
