Which of the following is a primary risk factor for coronary heart disease?

• A. High Blood Pressure
• B. Low Blood Pressure
• C. Regular Physical Activity
• D. High Cholesterol

Answer: (A)

High blood pressure is a primary risk factor for coronary heart disease because elevated pressure damages arterial walls and accelerates the buildup of plaques (atherosclerosis) that narrow or block arteries supplying the heart. This makes heart tissue receive less oxygen and can lead to a heart attack. Low blood pressure doesn’t raise CHD risk, and regular physical activity actually lowers risk by improving heart health and helping control blood pressure and cholesterol. While high cholesterol is a risk factor, hypertension is the more impactful factor among the options, which is why it’s the best answer.
