What element is NOT considered a risk factor for myocardial infarction?

Regular exercise is considered a protective factor against myocardial infarction rather than a risk factor. Engaging in regular physical activity has been shown to improve cardiovascular health, help maintain healthy weight, lower blood pressure, and improve cholesterol levels. These benefits collectively contribute to a reduced risk of developing heart disease, including myocardial infarction.

In contrast, hypertension, a family history of heart disease, and smoking are well-documented risk factors that can significantly increase the likelihood of a myocardial infarction. High blood pressure can lead to damage of the arteries, while a family history indicates a genetic predisposition to cardiovascular issues. Smoking, on the other hand, causes direct harm to the heart and blood vessels, increasing the risk substantially. Regular exercise stands apart from these factors as it actively contributes to heart health, highlighting its role as a protective element rather than a risk.
