Key result
Successful PTCA and CABG after failed PTCA both significantly improved work capacity from baseline (e.g., 74 to 122 W for PTCA; P<0.005), indicating failed PTCA does not compromise CABG outcomes.

Supports preserved functional gains after failed PTCA with rescue CABG; leaves open applicability to contemporary PCI and non-exercise outcomes.
Cohort (n=169)
Does successful PTCA or CABG after failed PTCA improve long-term exercise performance in patients undergoing PTCA?
p-value: p=<0.005
Both successful PTCA and CABG after failed PTCA significantly improve long-term work capacity, indicating that a failed PTCA attempt does not compromise the functional outcome of subsequent CABG.
Meier et al. (1983) conducted a cohort in Coronary artery disease requiring revascularization (n=169). Successful PTCA vs. Failed PTCA followed by CABG was evaluated on Exercise performance expressed as work capacity in watts (p=<0.005). Successful PTCA and CABG after failed PTCA both significantly improved work capacity from baseline (e.g., 74 to 122 W for PTCA; P<0.005), indicating failed PTCA does not compromise CABG outcomes.
