Effect of primary and fractional complete revascularization interventional therapy on the clinical prognosis of patients with ST-segment elevation acute myocardial infarction complicated with multi-vessel disease
Objective To analyze the effect of complete revascularization in single and staged percutaneous coronary intervention(PCI)on the clinical prognosis of patients with ST-segment elevation acute myocardial infarction(STEMI)complicated with multivessel disease(MVD).Methods A total of 76 patients with STEMI and MVD admitted to People's Hospital of Deyang from February 2021 to February 2022 were retrospectively analyzed.According to the treatment methods,they were divided into the study group(n=38)and the control group(n=38).The study group underwent staged PCI complete revascularization,and the control group underwent single PCI complete revascularization.The number of diseased vessels,the rate of left main coronary artery disease,the total amount of contrast agent,the total number of stents,the length of hospital stay and the incidence of major adverse cardiovascular events(MACE)(target vessel revascularization,cardiac death,recurrent myocardial infarction)were compared between the two groups.Results The total amount of contrast agent and total number of stents in the study group were(374.84±123.39)mL and(3.61±1.34)pieces,respectively,which were significantly higher than those in the control group[(235.97±94.05)mL and(2.77±0.86)pieces],the hospital stay was(11.53±4.29)d,which was significantly longer than that in the control group[(8.35±5.67)d],and the differences were statistically significant(P＜0.05);there were no statistically significant differences in the number of diseased blood vessels and the incidence of left main trunk disease between the two groups(P＞0.05).The incidence of MACE in the study group was 2.63％,which was significantly lower than that in the control group(21.05％),and the difference was statistically significant(P＜0.05).Conclusion Staged PCI complete revascularization can further reduce the incidence of MACE in patients with STEMI and MVD.
