We recently published increasing trend in the rate of percutaneous coronary intervention (PCI) In the United States. The goal of this study was to evaluate this trend in obese patient undergoing PCI in the United States.
The Nationwide Inpatient Sample (NIS) database was utilized to calculate the age-adjusted incident rate of PCI performed in obese patient from 1988 to 2006 in the United States using ICD-9 coding.
A total population of 122,023 obese patients underwent PCI between 1988-2006 were available for our study. We found that age adjusted rate of PCI performed in obese patient gradually increased with highest rate in 2006. Age adjusted rate for Obese patients undergoing PCI was PCI per 100,000 in 1988 was 2.7 vs. 24.1 per 100.000 in 2006 (p<0.01). Non-obese patient had similar increase in PCI over the years studied.
PCI performed in obese patient had increased steadily in last few decades. The cause of this trend is not known but could be related to increasing in obesity incidence or PCI is performed more frequently in high risk patients.
