    Cardiovascular disease includes a number of conditions affecting the structures or function of the heart. They can include:

    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 cardiovascular 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.

    Heart Failure

    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. This then leads to salt and water retention, causing swelling and shortness of breath. The swelling and shortness of breath are the primary symptoms of heart failure.

    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

    diseases affecting heart and cardiovascular system

    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 problems include mitral valve prolapse, aortic stenosis, and mitral valve insufficiency.
