Original description
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.Read full original descriptionShow less

A Comparative Study of the Effectiveness of Radial Artery and No-touch Vein in Coronary Artery Bypass Grafting in Women

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.

Inclusion: Three-vessel disease involving the target circumflex artery with stenosis ≥70% and a diameter ≥1.5 mm; Females aged 18 years and older; Signed informed consent; Clinical indications for coronary revascularization (refractory angina/transient myocardial ischemia according to noninvasive tests).

Exclusion: Previous cardiac surgery of any type, including CABG; Acute myocardial ischemia; Inability to understand the nature, scope, and consequences of the clinical trial, or to provide written informed consent due to cognitive impairment or mental illness; Life expectancy less than 1 year due to non-cardiac diseases; Combined procedures; Ineligibility for venous or radial artery harvesting as determined by preoperative Doppler flowmetry or clinical examination that would compromise graft patency; EF less than 35%; CKD 4.5.
