On average, the heart pumps about 2.5 billion times over your lifetime, moving millions of gallons worth of blood through the highway of blood vessels that reach each and every cell in your body. This network represents your cardiovascular (CV) system, which can be affected by a number of diseases like heart attacks, stroke, heart failure, arrhythmias, and heart valve problems. In the United States, someone has a heart attack every 40 seconds, and cardiovascular disease is considered the number one killer of both men and women.
