Abstract
Advances in pharmacotherapy for stable angina have produced a wide choice of drugs with various mechanisms of action, potentially enabling individualized, patient-specific treatment strategies to be developed. In this Review, the various treatment options for patients with stable angina are discussed. Data from randomized, clinical trials of established and novel drugs are reviewed, with particular emphasis on the proposed mechanisms of action, benefits of therapy, and adverse-effect profiles. The role of coronary revascularization in conjunction with optimal medical therapy as a treatment strategy is discussed, although drug therapy might reduce the need for prompt revascularization if the procedure is being considered solely for the purpose of alleviating angina. Finally, trials to investigate stimulation of angiogenesis using growth-factor, gene, and cell therapy are used to illustrate the challenges of chemically inducing the growth of adequate, durable blood vessels.
Key Points
-
No antianginal pharmacotherapy has been shown to prolong life or prevent myocardial infarction in patients with stable angina and normal left ventricular function, but drugs can improve quality of life
-
Multiple classes of drugs are available to manage stable angina; the choice of therapy should be individualized depending on comorbid conditions and left ventricular systolic function
-
β-Adrenergic-receptor blockers are the usual first-line therapy to reduce the myocardial oxygen requirements that occur with physical exertion—a common precipitating cause of angina
-
Ivabradine and ranolazine are two novel drugs with demonstrated efficacy and safety that expand therapeutic options for patients with stable angina
-
Coronary revascularization can alleviate angina more effectively than antianginal drugs; however, in the absence of high-risk coronary disease, optimal therapy with antianginal medications can obviate the need for coronary revascularization
-
Investigational therapies that stimulate angiogenesis are early in development and require much larger trials of efficacy and safety than previously performed, to assess their potential treatment benefit
