Cardiovascular disease is the leading cause of death in the US, affecting over 1 in 3 Americans. While historically thought of as a "man's disease", CVD kills nearly the same number of women and men each year. Risk factors include age, family history, smoking, high blood pressure, cholesterol levels, diabetes, obesity, and physical inactivity. Maintaining a heart-healthy lifestyle through a balanced diet, exercise, weight control, and not smoking can help prevent and manage CVD. Prompt medical care is crucial for CVD events like heart attacks to increase survival chances.
