A study was made of cardiac pumping capacity in animals with local myocardial ischemia (9 experiments on cats), in 25 healthy persons and 21 patients suffering from coronary heart disease with stage I-IIA circulatory insufficiency using afterload characteristics (ALC). The latter reflected correlation between left ventricular pressure and aortic blood flow in constant blood filling and in a given inotropic heart condition. For combined assessment of ALC one should know its two parameters: power (maximum pressure in the zero blood flow) and rate (maximum blood flow rate in zero antipressure). It was shown that early stages of cardiac insufficiency were characterized both under experimental and clinical conditions by change in the inclination angle of an afterload curve and a shift of a working point on it to the right. |
