Which statement about cardiovascular disease is true?

• A. It is the least common cause of death in the United States.
• B. It has no connection to lifestyle factors.
• C. It affects only the elderly.
• D. It is the leading cause of death in the United States; risk factors include smoking, lack of physical activity, and poor nutrition.

Answer: (D)

The main idea is that cardiovascular disease is the leading cause of death in the United States and is strongly influenced by lifestyle choices. This disease includes heart disease and stroke, and its risk is closely tied to daily habits. Smoking damages arteries, raises blood pressure, and increases heart attack and stroke risk. Not getting enough physical activity contributes to obesity, high blood pressure, and poor cholesterol levels. A diet high in unhealthy fats, sodium, and added sugars can elevate blood pressure, cholesterol, and the risk of diabetes—all of which raise cardiovascular risk. Because these factors are modifiable, adopting a heart-healthy pattern—avoiding or quitting smoking, staying active, and eating well—significantly lowers risk. That’s why this statement is true: cardiovascular disease is the leading cause of death, and risk factors include smoking, lack of physical activity, and poor nutrition. The other statements don’t fit because cardiovascular disease is not the least common cause, it is connected to lifestyle, and it does not only affect the elderly.
