AimRecently, monocyte-to-high density lipoprotein ratio (MHR) has been proposed as a novel prognostic indicator of cardiovascular diseases. However, no study is currently available regarding the comparison between MHR and monocyte count (MC) in predicting the outcomes among patients undergoing coronary angiography.MethodsA total of 3798 patients scheduled for selective coronary angiography were enrolled and followed up to capture major adverse cardiovascular events (MACEs, death, acute myocardial infarction, unstable angina, stroke, heart failure, and unexpected coronary revascularization). Cox proportional hazards models were used to evaluate the risk of MHR or MC on MACEs.ResultsDuring a median of 24.6 months follow-up, 347 (9.1%) MACEs occurred. The upper tertiles of MC and MHR have a significant lower event-free survival (p = 0.011; p = 0.014, respectively). Significantly, both MC and MHR were associated with increased MACEs risk after adjusting for potential confounders [adjusted HR (95% CI): 2.734 (1.547-4.832); 2.031 (1.268-3.254), respectively]. Additionally, the area under the receiver-operating characteristic curves of MC or MHR in predicting MACEs were 0.574 (0.542-0.606) and 0.562 (0.530-0.594) (p < 0.001, both), respectively.ConclusionsOur data firstly indicated that MHR was an independent predictor of MACEs whereas the prognostic impact was not superior to MC in patients who underwent coronary angiography. Key Messages MHR has been suggested as a novel prognostic indicator of several cardiovascular diseases. No study is currently available regarding the comparison of MHR to MC in predicting the outcomes in a large cohort of patients undergoing coronary angiography. Our data firstly indicate that MHR is independently associated with MACEs in patients undergoing coronary angiography whereas the prognostic impact is similar to MC.
