Supports careful risk assessment in elderly and reoperative CABS patients; leaves open demographic and PTCA effects on trends.
How do changing patient demographics and the advent of PTCA affect operative mortality in patients undergoing CABS?
The operative mortality of CABS is increasing due to a demographic shift towards older, higher-risk patients with lower ejection fractions, as younger, lower-risk patients increasingly undergo PTCA.
