Which of the following is a common risk factor for angina?

Hypertension is a common risk factor for angina because elevated blood pressure puts additional strain on the heart, leading to an increased demand for oxygen. When the heart's oxygen supply does not meet this increased demand, angina, which is characterized by chest pain or discomfort, can occur. Chronic high blood pressure can also lead to other cardiovascular issues, such as the thickening of the heart muscle and narrowing of blood vessels, further contributing to the risk of angina and other heart-related problems.

In contrast, low cholesterol levels are typically not associated with an increased risk of angina. High physical activity levels generally promote cardiovascular health and help prevent angina rather than contribute to it. Young age is also typically associated with a lower risk of developing angina, as many risk factors, including hypertension, often accumulate with age.
