Assessment of intracoronary stenting in acute myocardial infarction complicated by cardiac shock / 中国介入心脏病学杂志

ABSTRACT

Objective To observe the effect and safety of emergent intracoronary stenting in acute myocardial infarction (AMI) complicated by acute pump failure.Methods Fifteen patients with anterier wall AMI and apparent signs of cardiac shock were (70.1?8.4) years old on average. Their mean blood pressures were less than 85/60 mm?Hg and the ejection fractions (EF) were less than 42% on echocardiography. All the cases were performed in plantation of stenting in left anterior discending branch (LAD), among which, 4 were in right anterior artery (RCA) and 3 in left circumflex (LCX). Before and after stenting, the changes of the patients′ blood pressures, heart rates and cardiac functions tested by ultrasonography were observed. Results In 15 patients, whose LADs were completely occlusive, after stenting, the coronary arteries gained perfect reperfusion. Compared before and after stenting, the blood pressures were increased significantly after stenting [SBP (106?11.8) vs (76.2?4.9)mm?Hg, P
