[Use of beta blockaders in patients with ischemic heart disease during in-hospital rehabilitation after aortocoronary bypass surgery].

After studying central hemodynamics in patients with ischemic heart disease who had undergone aortocoronary shunting without postoperative complications and angina pectoris, the authors came to the conclusion on the beneficial effect of small-dose beta-blockers in the above cases if they developed sinus tachycardia. Beta-blockers help reduce oxygen demand of the myocardium and make more effective cardiac performance.
