List common contraindications to exercise for individuals with cardiovascular diseases.

The identification of uncontrolled hypertension and unstable angina as contraindications to exercise for individuals with cardiovascular diseases is rooted in the understanding of how these conditions can compromise heart function and overall health during physical activity.

Uncontrolled hypertension refers to consistently high blood pressure that is not adequately managed with lifestyle changes or medication. Engaging in exercise under these circumstances can increase the risk of hypertensive emergencies, which may lead to serious cardiovascular events such as stroke or heart attack. When blood pressure is not under control, the heart is under increased strain, which can exacerbate existing heart problems.

Unstable angina, on the other hand, is characterized by unpredictable and deteriorating chest pain that can occur at rest or with minimal exertion. This indicates a significant risk of acute coronary events, as it reflects a critical situation where the heart is not receiving enough oxygen and is under distress. Exercising with unstable angina could trigger serious complications, making it a clear contraindication in recommending exercise until the condition is stabilized.

In contrast, stable angina is often managed with medications and lifestyle modifications, and individuals with controlled hypertension are generally encouraged to engage in physical activity with professional guidance. Minor depression, although it may affect motivation and energy levels, does not typically pose a direct threat to
