Heart failure can happen in two ways. The heart muscle may become weak and enlarged (systolic dysfunction). The weakened muscle doesn’t pump enough blood forward when the ventricles contract. Or, the heart muscle may become stiff (diastolic dysfunction). The stiff muscle can’t relax between contractions, which keeps the ventricles from filling with enough blood.

BNP is a hormone produced by the body when the heart is enlarged. Testing a person's BNP level is an easy and accurate way to help doctors diagnose congestive heart failure.

You often hear only bad news about heart disease. After all, it is the leading cause of death in the United States, killing one in five people.

The heart, a powerful muscle that beats over 50,000 times in one day, is fed the blood and energy it needs through small tubes called coronary arteries (see Figure 1). Coronary artery disease (CAD) is the most common cause of death and disability in the United States and other industrialized countries, and it can be manifested if these arteries become narrowed by cholesterol to about half their normal diameter (see Figure 2).
