急性心肌塞(AMI)后,由于坏死部分心肌失去正常收缩功能,使左室壁舒缩运动不协调,导致心室射血功能降低,左室腔内残留血量增多,室壁在收缩及舒张期受到的应力增加,引起左室腔扩大伴形态改变,称为左室重构。左室重构使病人心功能减退,并发症出现率及死亡率明显增加。因此,掌握其发生机
Acute myocardial infarction (AMI), due to necrosis of the part of the heart to lose normal systolic function, so that the left ventricular wall contraction and relaxation movements are not coordinated, leading to decreased ventricular ejection function, left ventricular cavity residual blood volume increased, ventricular wall contraction and diastolic By the increase of stress, causing the left ventricular cavity with the morphological changes, known as left ventricular remodeling. Left ventricular remodeling makes the patient’s cardiac function decline, the incidence of complications and mortality increased significantly. So take control of what happened
