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.eninfo:eu-repo/semantics/openAccess[No Keyword]Article755WOS:0006053093000012-s2.0-850991772313336888210.1111/ijcp.13973Q2Q2
