ABSTRACT
OBJECTIVE:
To analyze the predictive factors of complications after implantation of coronary stents in a consecutive cohort study.METHODS:
Clinical and angiographic characteristics related to the procedure were analyzed, and the incidence of major cardiovascular complications (myocardial infarction, urgent surgery, new angioplasty, death) in the in-hospital phase were recorded. Data were stored in an Access database and analyzed by using the SPSS 6.0 statistical program and a stepwise backwards multiple logistic regression model.RESULTS:
One thousand eighteen (mean age of 61±11 years, 29 percent females) patients underwent 1,070 stent implantations. The rate of angiographic success was 96.8 percent, the rate of clinical success was 91 percent, and the incidence of major cardiovascular complications was 7.9 percent. The variables independently associated with major cardiovascular complications, with their respective odds ratio (OR) were rescue stent, OR = 5.1 (2.7-9.6); filamentary stent, OR = 4.5 (2.2-9.1); first-generation tubular stent, OR = 2.4 (1.2-4.6); multiple stents, OR = 3 (1.6-5.6); complexity of the lesion, OR = 2.4 (1.1-5.1); thrombus, OR = 2 (1.1-3.5).CONCLUSION:
The results stress the importance of angiographic variables and techniques in the risk of complications and draw attention to the influence of the stent's design on the result of the procedure
