Procedural difficulty and immediate outcome of percutaneous coronary intervention in patients with myocardial infarction / 介入放射学杂志

ABSTRACT

Objective To compare the procedural difficulty index (PDI) and immediate outcome (IM) of percutaneous coronary intervention (PCI) in patients with various stages of myocardial infarction.Methods Ninety-four patients with myocardial infarction were divided into three groups, direct PCI(n=38), delayed PCI(n=22) and late PCI(n=34). The characteristics of infarct-related coronary artery, PDI and IM of PCI were evaluated angiographically, and severe procedural complications (SPC) and major adverse cardiac events (MACE) during hospitalstay were documented. Results In the three groups, PDI was 1.47 ?1.79, 1.82 ?1.72 and 2.85 ?2.83, respectively (P
