Percutaneous coronary intervention in octogenarians in Brazil. Data from the last decade
DOI: 10.31160/JOTCI2018;26(1)A0011
ABSTRACT
Background
As the population ages, the prevalence of diseases has increased, particularly that of coronary artery disease requiring treatment. The objective of this study was to assess the temporal evolution of percutaneous coronary intervention in octogenarians in Brazil.
Methods
Based on data from the Central Nacional de Intervenções Cardiovasculares (CENIC), we analyzed procedures carried out in patients aged 80 years and over, from June 2006 to March 2016, classified into three time ranges: 2006-2008, 2009-2011 and 2012-2016. We assessed clinical and angiographic parameters, characteristics of the procedure and their in-hospital outcomes.
Results
Of the 176,780 percutaneous coronary interventions that took place during the study period, 14,148 were performed in 13,256 patients aged 80 years and older. The mean age was 83.6 years, and 52% were men. We observed greater prevalence of male, asymptomatic patients, with a history of acute myocardial infarction, prior percutaneous coronary intervention and Killip class 1. Concomitantly, there was a decrease in smoking, left main coronary artery interventions and multi-vessel disease patients. There was a progressive increase in the use of drug-eluting stents, thrombus aspiration devices, and stent length. The success rate of the procedures was high, and increased over the time periods (93.9% vs. 96.1% vs. 96.3%; p<0.0001), associated with a decrease in major adverse cardiac events (3.9% vs. 2.1% vs. 2.3%; p<0.0001).
Conclusions
Although more challenging, the treatment of octogenarian patients has become more frequent, with good outcomes and safety over the years.
