Comparison Of Complete And Incomplete Interventional Revascularization In The Treatment Of Multivessel Coronary Disease

Objective:To observe and analyze the clinical results of complete coronary interventional revascularization and incomplete interventional revascularization in the treatment of multivessel coronary disease, The immediate effects and long-term effects are compared between the two groups. The paper is mainly focus on judging the advantages and disadvantages about the two PCI methods and how to choose the ideal strategies for treatment of multivessel coronary disease.Methods:Clinical findings of patients with multivessel coronary disease treated by PCI of Cardiology of Shandong Provincial Hospital from January2012to January2013were collected and analyzed retrospectively, which including the general state of health, related risk factors, biochemical indicators, ECG and ultrasound of cardiology. The patients are divided into two groups:complete interventional revascularization group(CIRVG) and incomplete interventional revascularization group(IIRVG), according to the coronary angiographic features. All the patients were followed up after the PCI, and major adverse cardiac events(MACEs, including cardiac death, myocardial infarction, and target vessel revascularization) in hospital and out of hospital were recorded. The difference of MACEs and clinical data between groups were analyzed. T test and Chi-square test were carried out on the basis of a statistical software named SPSS17.0.Results:1. Among102patients with multivessel lesions,44cases treated with IIRVG and58cases treated with CIRVG were included. There were no difference in the basic clinical data and the risk factors between the two groups (P>0.05).2. The coronary angiography outcomes showed that there were38patients with double vessel disease,64cases with triple vessel disease,21patients with left main artery lesion,50patients with chronic total occlusion and29patients with bifurcation lesion. The rate of double vessel disease of CIRVG is significantly higher than IIRVG (53.4%vs15.9%, P<0.05), the rates of triple vessel disease and bifurcation lesion of IIRVG are much higher than CIRVG (P<0.05).3.1in-surgery patient with ventricular tachycardia then turned into complete atrioventricular block was cured with pace maker and another3in-hospital patients with ventricular fibrillation were cured with defibrillation.1patient suffered huge hematoma and2patients suffered acute or subacute thrombus and cured with thrombus aspiration. The rate of severe arrhythmia is much higher in the IIRVG than CIRVG (9.1%vs0, P<0.05).4. The follow-up statistics show that there are11cases of total MACE events. The rates of total MACE events and the angina recurrence of the IIRVG are significantly higher than CIRVG (P<0.05).Conclusions:1. Comparing with the incomplete interventional revascularization, the rate of severe arrhythmia is lower in the complete interventional revascularization.2. The rates of total MACE events and the angina recurrence of incomplete interventional revascularization is significantly higher than complete interventional revascularization.
