Which of the following patients would be most suitable for treatment with Verapamil?

Verapamil is a calcium channel blocker that is commonly used in the management of certain cardiovascular conditions, particularly stable angina. It works by relaxing the smooth muscles of blood vessels and decreasing the heart rate, which reduces myocardial oxygen demand. This mechanism is beneficial for patients experiencing stable angina, as it helps alleviate chest pain associated with reduced blood flow to the heart.

In the case of stable angina, the goal is to relieve chest pain and improve the patient's quality of life while managing their condition. Verapamil not only helps in controlling angina symptoms but also provides additional benefits such as lowering blood pressure and potentially improving exercise tolerance.

Patients with high-grade heart block or severe bradycardia may experience negative effects from Verapamil, as its actions can further slow down the heart rate. Similarly, those with significant hypotension would not be appropriate candidates for this medication, given that it can lower blood pressure further. Hence, a patient with stable angina is the most suitable choice for treatment with Verapamil.
