Monocyte to high-density lipoprotein cholesterol and lymphocyte to monocyte ratios are predictors of in-hospital and long-term mortality in patients with acute coronary syndrome.

Objective: We aimed to determine the relationship between LMR and MHR and in-hospital and long-term mortality in patients with ACS.

Methods: We retrospectively collected patients with ACS undergoing coronary angiography between January 2012 and December 2013.

Results: In total, 825 patients with a mean age of 62.4 ± 12.9 years (71.3% male) were enrolled in the study. Patients were divided into three tertiles based on MHR levels and LMR levels. In-hospital mortality of the patients was significantly higher amongst patients in the upper MHR tertile when compared with the lower and middle MHR tertile groups [30 (10.9%) vs 8 (2.9%) and 14 (5.1%); P < .001, P = .009, respectively]. Five-year mortality of the patients was significantly higher amongst patients in the upper MHR tertile when compared with the lower and middle MHR tertile groups [84 (30.5%) vs 48 (17.5%) and 57 (20.7%); P < .001, P = .005, respectively]. In-hospital mortality of the patients was significantly higher amongst patients in the lower LMR tertile when compared with the upper and middle LMR tertile groups [25 (9.1%) vs 10 (3.6%) and 17 (6.2%); P = .007, P = .130, respectively]. Five -year mortality of the patients was significantly higher amongst patients in the lower LMR tertile when compared with the upper and middle LMR tertile groups [77 (28.0%) vs 47 (17.1%) and 65 (23.6%); P = .001, P = .142, respectively].

Conclusion: We have shown that high MHR and low LMR were significant and independent predictors of in-hospital and long-term mortality in patients with ACS.
