Percutaneous coronary intervention in patients with multivessel disease in Brazil
DOI: 10.31160/JOTCI2017;25(1-4)A0009
ABSTRACT
Introduction:
Percutaneous coronary intervention (PCI) in patients with multivessel disease is associated with a lower success rate and a higher incidence of complications. The results of this treatment in Brazil are poorly studied. The objective of this study was to analyze the results of PCI performed in patients with multivessel disease, which were registered in the National Center for Cardiovascular Interventions (CENIC) registry.
Methods:
Complete electronic records of procedures performed in patients with multivessel disease from 2006 to 2016 were analyzed.
Results:
A total of 191,127 PCI were submitted to the CENIC registry in the study period, including 80,093 (45.3%) cases classified as multivessel disease. The patients were predominantly male (67.5%) with stable (49.6%), twovessel disease (65%). Type B2/C lesions were present in 70.8% of the cases, with a mean of 1.6 artery treated per patient and 1.7 stent implanted per procedure, 71.6% of which were bare-metal stents. The success rate was 96%. During hospitalization, the occurrence of major adverse cardiac events was 1.5%, and death was the most frequent complication (1.2%). Independent predictive factors of death were age, sex, diabetes mellitus, previous infarction, the extent of coronary disease, the use of glycoprotein IIb/IIIa inhibitors, acute coronary syndrome, emergency interventions and procedures undertaken in the 2006-2008 period.
Conclusions:
Multivessel PCI has a high success and a low in-hospital complication rate. The identification of characteristics associated with a poor prognosis can be useful for stratification and for the selection of the most appropriate treatment strategy.
