Use and in-hospital mortality associated with two cardiac procedures, by sex and age: national trends, 1990-2004.

This study used data from the National Hospital Discharge Survey to examine sex- and age-specific trends in use and in-hospital mortality associated with coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) among adults age forty-five and older during 1990-2004. Although use rates for PCI increased 58 percent over the study period, CABG use rates declined. In-hospital death rates declined or stayed the same even though comorbidities increased for patients who received the procedures. PCI and CABG use rates for men were at least twice those for women, although women generally had more comorbidities and higher in-hospital death rates.
