In-hospital outcomes and mortality in octogenarians after percutaneous coronary intervention.


PMID 25563471

Abstract

There is systematic growth in the number of number of elderly patients treated with percutaneous coronary intervention (PCI); however, little is known about PCI results in the very elderly (long-lived) patients aged 85 years and above. To assess the demographic, clinical, and angiographic findings in patients aged > 85 years (GER), undergoing PCI, compared with younger patients treated in the year 2012. This was a single centre retrospective study based on a consecutive group of 920 patients with coronary disease (stable and acute coronary syndrome [ACS]). Patients were divided into two groups: GER aged 85 years and over (n = 82) and controls (CG) below 85 years (n = 838). The mean age in the GER group was 88.6 vs. 66.7 years in the CG. There were more females in the GER group (57% vs. 29%) than in the CG (p < 0.001). The indication for PCI was mainly ACS in GER (65%) vs. CG (50%) including ST segment elevation myocardial infarction (STEMI) 30% vs. 29% (p = NS), ACS non-STEMI 35% vs. 20% (p = 0.01). GER patients had more comorbidities and more advanced multivessel coronary artery disease. The ratio of procedural success was lower in GER compared to CG. The incidence of in-hospital death was higher in GER (4.8%) compared to CG (0.83%); the most common complication in GER group was contrast-induced nephropathy (18.2% vs. 6.2%). Major adverse cardiovascular events were significantly more frequent in GER patients with ACS compared to CG patients with the same diagnosis. Patients > 85 years old, especially with ACS undergoing PCI, are at greater risk of in-hospital complications, especially contrast-induced nephropathy and procedural complications, compared to younger patients.
