What is the first-line treatment for controlling angina in a patient with stable ischemic heart disease?

The first-line treatment for controlling angina in a patient with stable ischemic heart disease typically centers around the use of beta-blockers. Carvedilol, a non-selective beta-blocker with alpha-blocking properties, effectively reduces heart rate and myocardial oxygen demand, making it beneficial for patients experiencing angina from ischemic heart disease. By decreasing the workload on the heart, carvedilol can alleviate symptoms of angina and improve exercise tolerance.

Beta-blockers such as carvedilol are supported by clinical guidelines as the initial pharmacotherapy for stable angina because they have been shown to reduce the frequency of angina episodes and improve overall cardiovascular outcomes. Their efficacy in controlling heart rate and reducing myocardial oxygen demand aligns with the goals of managing stable angina.

In comparison, other listed options, while they may have utility in treating other aspects of cardiovascular health, do not serve as the first-line agents specifically for angina control in stable ischemic heart disease. For instance, lisinopril is primarily an ACE inhibitor used for blood pressure management and heart failure rather than immediate angina control. Ranolazine is an anti-anginal agent that may be used as a second-line treatment, especially in patients who cannot tolerate or whose angina is not
