Association between non-high-density lipoprotein cholesterol and high-density lipoprotein cholesterol ratio (NHHR) at 1 year after coronary artery bypass grafting and long-term outcomes in patients with multiple vessel disease: a retrospective cohort study

The non-high-density lipoprotein cholesterol-to-high-density lipoprotein cholesterol ratio (NHHR) has emerged as a promising lipid predictor for various cardiovascular conditions. However, its role in predicting long-term outcomes after coronary artery bypass grafting (CABG), particularly in multivessel disease (MVD) patients, remains unclear. We conducted a retrospective study of MVD patients who underwent CABG between 2011 and 2020. Patients were stratified into NHHR quartiles at baseline and
