ABSTRACT
Objective: To analyze predictive value of plane QRS-T angle for postoperative malignant ventricular arrhythmia (MVA) of patients with acute myocardial infarction (AMI) who underwent PCI and the correlation between the predictive value and prognostic effect. Methods: The clinical data of 100 patients with AMI who underwent the treatment of percutaneous coronary intervention(PCI) were researched by using retrospective analysis. All of patients were divided into observation group (24 cases) and control group (76 cases) according to the angle of plane QRS-T after PCI. The plane QRS-T angle of observation group was more than 90°, and it was less than or equal to 90° in control group. The occurrence of MVA and clinical outcome of MVA between the two group were compared. Results: The age of observation group was significantly higher than that of control group (t=3.516, P<0.05). The interval of QTc of observation group was significantly higher than that of control group (t=2.131, P<0.05). And the percentage of left ventricular ejection fraction (LVEF) less than 45%, the occurrence rate of high blood pressure and the occurrence rate of MVA of observation group were significantly higher than those of control group (x2=3.922, x2=3.950, x2=5.942, P<0.05), respectively. The results of multi-factor Logistic regression analysis indicated that the angle of plane QRS-T of patients with AMI after PCI above 90° was the independent risk factor of MVA after PCI (OR=9.640, P<0.05). Conclusion: After the PCI of patients with AMI, the QRS-T angle> 90 ° was an independent risk factor of MVA.
