What this Trial Is About
This study examines the outcomes of coronary artery bypass grafting (CABG) in women at 1 year after surgery. A randomized controlled trial is planned, including a comparative analysis of two observed groups depending on the chosen conduit for revascularization of the circumflex artery. The main group is supposed to include 55 patients undergoing CABG with the use of the radial artery, while the control group will include 55 patients undergoing CABG with the use of the great saphenous vein prepared using the no-touch technique.
