Which of the following is NOT a risk factor for myocardial infarction?

• A. Hypertension
• B. Smoking
• C. Regular exercise
• D. Diabetes Mellitus

Answer: (C)

Regular exercise is associated with a reduced risk of myocardial infarction and is considered a protective factor for heart health rather than a risk factor. Engaging in regular physical activity helps improve cardiovascular fitness, manage weight, lower blood pressure, and reduce the likelihood of developing conditions such as hypertension and diabetes. In contrast, hypertension, smoking, and diabetes mellitus are well-established risk factors for myocardial infarction, contributing to the development of atherosclerosis and increasing the strain on the heart. Therefore, identifying regular exercise as a positive lifestyle choice reinforces the importance of physical activity in preventing heart disease.
