应用血管扩张剂改善心泵的工作性能,是近十年来治疗急性心肌梗死(AMI)并发泵衰竭(急性左心衰竭和心源性休克)最重要的进展之一,这一疗法现已推广到慢性顽固性充血性心力衰竭,而且对于某些机械性障碍引起的泵衰竭(如严重二尖瓣和主动脉瓣关闭不全所致的二尖瓣返流和主动脉瓣返流,室间隔缺损所致的左右分流,高度二尖瓣狭窄所致的肺郁血等)也有一定的缓解作用。
One of the most important advances in the treatment of acute myocardial infarction (AMI) complicated with pump failure (acute left heart failure and cardiogenic shock) in the last decade has been the application of vasodilators to improve the performance of cardiac pumps. This therapy has been extended to Chronic intractable congestive heart failure, but also for some mechanical disorders caused by pump failure (such as severe mitral and aortic regurgitation caused by mitral regurgitation and aortic regurgitation, ventricular septal defect Induced left and right shunt, a high degree of mitral stenosis caused by pulmonary depression, etc.) also have some relief.
