Counterpulsation and Intraaortic Balloon Pumping in Cardiogenic Shock

摘要: THE MORTALITY of shock associated with myocardial infarction has been reported as between 24% and 93%1with averages in the range 70% to 80%, depending upon criteria diagnosis. Because failure medicinal therapy including vasopressors salvage majority such patients, recent emphasis placed on mechanical means for assisting acutely failing heart. Of available methods, cardiopulmonary bypass2invokes need major surgery causes significant injury cellular components blood. Venoarterial pumping does not increase central aortic pressure coronary perfusion,3nor it reduce left ventricular work may, fact, it; its primary application is right heart failure. Bypass side without thoracotomy4does atrial work, but large vessels cardiac chambers may result from rigid
