Description
Summary:This study aims to observe the effects of the intracoronary and peripheral venous administration of nicorandil for the postoperative myocardial microcirculation and short-term prognosis of ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PPCI) treatment. A total of 140 STEMI patients were divided into three groups according to different patterns of administration: sequential nicorandil group, intracoronary nicorandil group and control group. The main observation indexes included coronary blood flow and myocardial perfusion immediately after PPCI, while the secondary observation indexes included major adverse cardiovascular events (MACE) and left ventricular ejection fraction (LVEF) during the period of hospitalization. After PPCI, the difference in the proportion of patients with thrombolysis in myocardial infarction (TIMI) flow grade 3 among the three groups was statistically significant (P=0.036), where this proportion was higher in the sequential nicorandil group and intracoronary nicorandil group than in the control group (P=0.022 and P=0.047); The difference in corrected TIMI frame count (CTFC) among the three groups was statistically significant (P=0.022), where CTFC was lower in the sequential nicorandil group and intracoronary nicorandil group than in the control group (P=0.010, P=0.031); The differences in the proportion of patients with complete ST resolution (STR) and advancing of enzyme peak time to within 12 h between each two groups were statistically significant (P
