治疗心力衰竭的基本目标是使心室容易排空,从而增加心搏出量。充血性心力衰竭的常规治疗着重于使用正性收缩能药物和利尿药,以增加心室搏出量和心排出量。冠心病患者由于心肌收缩单位受损和减少而产生的顽固性泵衰竭,增强其剩余尚有功能心肌的正性收缩能作用,虽可在一定程度上提高心搏出量,但仍不足以改善心脏工作。而且,强心药物引起的强力正性收缩能作用,可增加心肌的总需氧量,因而对缺血性心脏病不
The basic goal of treating heart failure is to make it easier for the ventricle to empty, thereby increasing the amount of cardiac output. Routine treatment of congestive heart failure focuses on the use of positive systolic and diuretic drugs to increase ventricular stroke and cardiac output. Coronary heart disease patients due to myocardial damage caused by reduced and reduced intractable pump failure to enhance the positive function of its remaining functional myocardial systolic function, although to a certain extent, improve cardiac output, but still not enough to improve Heart work. Moreover, the strong positive cardiac contractions caused by drugs can play a role, can increase the total myocardial oxygen demand, and therefore not ischemic heart disease
