In patients with stable angina,<unk><unk>  are used as a first line of therapy for both, symptomatic relief and the prevention of ischemic events. The physiologic mechanism of benefit of this therapy is a marked reduction in myocardial oxygen consumption by reducing the heart rate and myocardial contractility. Selective<unk> -1<unk>  are preferred to non-selective<unk><unk>  due to fewer associated side effects. The most commonly used selective<unk> -1<unk>  are metoprolol, atenolol, and bisoprolol.
