Objective By analyzing and comparing the effects of different revascularization strategies on patients with acute myocardial infarction complicated with multi-vessel disease, to explore its clinical value.Methods Selecting the patients with acute myocardial infarction complicated with multi-vessel disease from August, 2012 to August, 2015 in our hospital (Zhaoqing No.2 People's Hospital), after each patient was successfully treated with PCI, divided them into experimental group and control group by random number table method, the experimental groups were treated with preventive emergency PCI after the onset 7-10 days, and the intervention of non-infarct-related vascular diseases were done;the control groups were treated with emergency PCI for the non-infarct-related vascular diseases according to the patient's lack of blood. Visiting them randomly for 2 years, the main cardiac adverse events, other cardiovascular events and one more emergency PCI situation in the two groups were recorded.Results A total of 450 patients completed two years of follow-up, with 226 patients in the experimental group and 224 patients in the control group. All-cause mortality (χ2=7.040,P=0.008), cardiac adverse events (P> 0.05)and incidence of heart failure (χ2=1. 527,P=0.217) were no statistically significant difference between the two groups. Compared with the control group, the incidence of angina pectoris (χ2=21.092,P<0.001), cardiologic rehospitalization (χ2=22.893,P<0.001)and one more stent treatment (χ2=17.835,P<0.001) of the experimental group was significantly lower, but the revascularization rate was higher of their related blood vessels. And when the experimental group was followed up for 2 years, the taking rate of β-blockers (χ2=7.040,P=0.008) and nitrates (χ2=63.889,P<0.001) was significantly higher.Conclusion After the patients with acute myocardial infarction complicated with multi-vessel disease were successfully treated with emergency PCI to intervene the infarct-related blood vessels, and at the same time the intervention of the non-infarct-related blood vessels were done, the recurrence of angina pectoris, stent treatment and cardiopulmonary rehospitalization was significantly reduced.
