An Introduction to Cardiovascular Disease in Women
Many women think
cardiovascular disease is a man's problem. However, cardiovascular disease is the number-one killer of women in the United States. In fact, cardiovascular disease in women is responsible for 1 in 2 deaths;
breast cancer is responsible for 1 in 23.
What exactly is cardiovascular disease? Cardiovascular disease is the name used to describe conditions that affect the heart ("cardio") and/or blood vessels ("vascular"). There are over 60 types of cardiovascular disease, the most common forms being coronary
heart disease (usually just referred to as heart disease),
high blood pressure, and
stroke.
Understanding the Cardiovascular System
The heart is a strong, muscular pump that is slightly larger than your fist.
It pumps blood continuously through the circulatory system, the network of elastic tubes that allows blood to flow throughout the body. The
cardiovascular system includes the heart and also the blood vessels (arteries, capillaries, and veins). Arteries and capillaries carry oxygen- and nutrient-rich blood from the heart and lungs to all parts of the body. Veins carry blood that has been depleted of oxygen and nutrients back to the heart and lungs.
Heart and blood vessel problems do not happen quickly. Over time, the arteries that bring blood to the heart and brain can become blocked due to a buildup of cells, fat, and
cholesterol. This buildup is called
plaque. Reduced blood flow to the heart (due to blockages in the arteries) causes heart attacks. Lack of blood flow to the brain from a blood clot, or bleeding in the brain from a broken blood vessel, causes a stroke.
