Key result
Saphenous vein graft surgery significantly improved functional aerobic impairment by a mean of 16% (P<0.001), with improvements strongly correlated with graft patency.

Saphenous vein grafting was associated with improved exercise capacity in angina; leaves open outcome benefits versus contemporary medical or PCI strategies.

Does saphenous vein graft surgery improve maximal exercise performance in patients with angina pectoris?
p-value: p=<0.001
Saphenous vein bypass surgery significantly improves maximal exercise performance, with the greatest benefit seen in patients with severe preoperative exercise impairment and preserved ventricular function.
Lapin et al. (1973) conducted a cohort in Angina pectoris (n=46). Saphenous vein graft surgery (SVG) vs. Pre-surgery baseline was evaluated on Functional aerobic impairment (FAI) improvement (p=<0.001). Saphenous vein graft surgery significantly improved functional aerobic impairment by a mean of 16% (P<0.001), with improvements strongly correlated with graft patency.
