Background
Significant advances have been made in the last few decades. We have recently shown that PCI-related mortality has been declining in recent years. The goal of this study was to evaluate age-adjusted in-hospital mortality rate in patients undergoing percutaneous coronary intervention (PCI) based on race and gender.
Method
The Nationwide Inpatient Sample (NIS) database was utilized to calculate the age-adjusted mortality rate for PCI from 1988 to 2004 in patients over the age of 40 retrospectively. Specific ICD-9-CM codes for PCI were used for this study. Demographic data including race and gender was also analyzed and adjusted for age.
