Pre-N: prior to nicardipine administration; Post-N: post-nicardipine administration; LIMA-LAD: left internal mammary artery (LIMA) anastomosed to left anterior descending artery; A1, A2, A3: anastomose 1-3; SVGs: saphenous vein grafts.
Group A indicated no-touch vein harvest; Group B for conventional vein harvest.
