title: [Prevention of disorders of myocardial contractile function in patients with ischemic heart disease during aortocoronary shunting].
abstract: The efficacy of pre-, intra-, and postoperative prevention of hemodynamic disorders by creatinine phosphate, cytochrome C, and glutamic acid was evaluated in 61 coronary patients with decreased myocardial contractility. All these agents exerted a positive inotropic effect in coronary patients with ejection fraction below 0.4, increasing the stroke volume and left-ventricular ejection fraction without modifying heart rate. Glutamic acid is not recommended for preoperative treatment, because it increases oxygen consumption by the myocardium above the reserve potential of the coronary bed. Cytochrome C is the most effective drug for preoperative treatment. Intraoperative preischemic protection of the myocardium by cytochrome C in coronary patients during high risk operations prevents the development of unfavorable hemodynamic complications during induction and maintenance of anesthesia before artificial circulation, provides favorable recovery of cardiac activity, decreases the incidence of severe arrhythmias, promotes a rapid and full-value recovery of myocardial contractile function after ischemia, and decreases the incidence of acute heart failure.
