    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.

    Novel predictor of pulmonary arterial hypertension: Monocyte to HDL cholesterol ratio
    (Lippincott Williams & Wilkins, 2022) Bilik, Mehmet Zihni; Oylumlu, Muhammed; Oylumlu, Mustafa; Acun, Baris; Arik, Baran; Arslan, Bayram; Acet, Halit
    Monocyte to HDL cholesterol ratio (MHR), lymphocyte to monocyte ratio (LMR), and neutrophil to lymphocyte ratio (NLR) have been proposed as novel systemic inflammatory markers. The aim of this study was to explore the association between MHR, LMR and NLR with pulmonary arterial hypertension (PAH). The study is a single-center, retrospective Cross-sectional study. The study group consisted of 73 patients with PAH and the control group 77 participants without cardiac pathology as determined by echocardiography. On admission, blood sampling to calculate MHR, LMR, NLR, and detailed clinical data were obtained. According to the Pearson test, systolic pulmonary artery pressure (PAP) value Higher MHR, NLR and lower LMR that indicates an enhanced inflammation were significantly increased in patients with PAH when compared with controls. Compared to many other inflammatory markers, these markers are widely available. positively correlated with the MHR and NLR (r:.35, P < .001 and r:.33, P < .001, respectively), but negatively correlated with LMR (r: -.26, P = .001). After multivariate logistic regression analysis, MHR, LMR, and NLR remained as significant predictors of PAH (OR: 2.651, 95% CI: 1.227-5.755, P = .007; OR: 0.647, 95% CI:0.450-0.931, P = .005; OR: 1.350, 95% CI: 1.054-1.650 P = .030, respectively).
