[The anesthesiological risk and treatment characteristics of patients with ischemic heart disease prepared preoperatively with beta-receptor blockers, calcium antagonists and nitro preparations]. / Anesteziologichen risk i osobenosti v lechenieto na patsienti s iskhemichna bolest na surtseto, podgotveni predoperativno s beta-retseptorni blokeri, kaltsievi antagonisti i nitropreparati.

The anesthesiologic risk in ischemic heart disease (IHD) patients undergoing noncardiac surgery is determined by the duration of myocardial infarction sustained in the past, and the degree (severity) of stenocardia manifestations. Such risk is estimated as minimal within six months after myocardial infarction in the presence of stenocardia stabilization. In this contingent of patients the anti-ischemic therapy is proceeded with in both pre- and postoperative period. The role of beta-adrenergic blocking agents (propranolol, acebutolol, esmolol, sotalol) and calcium antagonists (nifedipine, diltiazem) in the prophylaxis against intraoperative myocardial ischemia, rhythm disorders and pathologic arterial pressure rise is definitely proved.
