脑钠肽(Btype natriuretic peptides BNP)主要由心脏分泌的循环激素,具有扩血管﹑利钠﹑利尿﹑抑制肾素﹑醛固酮分泌的作用。急性心肌梗塞早期BNP即明显升高,对急性心肌梗塞患者预后有很好的指导作用;心肌活动指数(myocardial performance index MPI)因不受超声条件、心脏几何形态、心室收缩及舒张压等影响,较之传统左室射血分数更为客观、准确,已被广泛应用于评价心功能。脑钠钛作为神经内分泌激素,心肌活动指数作为机械因素联合用于评价急性心肌梗死患者的预后及筛检急性冠脉事件的高危患者将起到更加重要的作用,本文现将两项指标在AMI最新研究进展作一综述。
Brain natriuretic peptide (BNP) is a circulating hormone secreted by the heart. It has vasodilator, natriuretic, and diuretic effects and inhibits the secretion of renin and aldosterone. Acute myocardial infarction in early BNP was significantly elevated, the prognosis of patients with acute myocardial infarction has a good guide; myocardial activity index (myocardial performance index MPI) due to ultrasound conditions, cardiac geometry, ventricular contraction and diastolic blood pressure and other effects, Compared with the traditional left ventricular ejection fraction more objective and accurate, has been widely used in the evaluation of cardiac function. Brain Natriuretic peptide as a neuroendocrine hormone, myocardial activity index as a mechanical factor combined for the evaluation of the prognosis of patients with acute myocardial infarction and screening for acute coronary events in high-risk patients will play a more important role, this article now two indicators AMI The latest research progress is reviewed.
