Explain why cardiovascular diseases are the leading cause of death in men and women in the United States.

Answer:

Cardiovascular diseases are the leading cause of death because they are common, can develop gradually without noticeable symptoms, and may suddenly cause fatal heart attacks or strokes. Risk factors such as high blood pressure, high cholesterol, smoking, physical inactivity, and unhealthy diets affect many people and can damage the heart and blood vessels over time.
