Background:
Prior studies have demonstrated higher risk of percutaneous coronary intervention (PCI) related mortality in the elderly patients, however limited data exists regarding the predictors of in-hospital mortality in these patients. The objective of our study was to compare the trend and predictors of mortality following PCI in patients aged 80 – 89 and ≥ 90 years.

Methods:
The National Inpatient Sample from the years 2005 – 2014 was used for analysis. The ICD9-CM codes were used to identify the patients who had PCI (36.06, 36.07, 00.66, 17.55). Multivariate logistic regression was performed to identify predictors for mortality. Cochran-Armitage test was used for mortality trend.

Results:
A total of 126,081 (unweighted) PCIs were reported in 80 - 89 years old patients (group 1) and 10,263 PCIs in patients ≥ 90 years old (group 2). The in-hospital mortality was 3.48% in group 1 and 7.02% in group 2. Significant increase in trend of mortality (p < 0.001) from 2005 – 2014 was noted in both the groups. Non-white race, acute myocardial infarction, congestive heart failure, peripheral vascular disease, and cerebrovascular disease demonstrated higher likelihood of mortality following PCI in both the groups. Gender, age and renal disease showed association with mortality in patients 80 – 89 years but not in patients ≥ 90 years.

Conclusions:
Several comorbid conditions were noted to be predictors of mortality. Further research is needed to identify appropriate patients to minimize post procedural mortality.
