Background and Objectives: Lymphocyte-to-monocyte ratio (LMR) has emerged as a new indirect marker of inflammation, which is associated with adverse outcomes in cardiovascular diseases. The aim of this study was to evaluate whether admission LMR is associated with contrast-induced nephropathy (CIN) in patients who underwent percutaneous coronary intervention for acute coronary syndrome (ACS). Methods: A total of 873 patients were assessed. LMR was calculated via dividing lymphocyte count by monocyte count. Results: LMR was significantly lower in the with-CIN group. ROC analysis showed that the LMR ratios <2.52 predicted CIN development with sensitivity of 66.3% and specificity of 55.8%. Multivariate analysis showed that eGFR, admission glucose, and LMR were independent predictors of CIN in patients with ACS. Conclusion: LMR is an easily accessible marker and could be used as a predictor of CIN in patients with ACS undergoing percutaneous coronary intervention.

Aim: The aim of the study was to investigate the monocyte count to HDL cholesterol ratio (MHR) on the prognosis of patients with hypertrophic cardiomyopathy (HCM). Materials & methods: A total of 411 patients with HCM were assessed. The primary end point was cardiovascular death or malignant arrhythmic events. Results: During the follow-up, primary end point was developed in 54 (13.1%) patients. Receiver operating characteristic (ROC) analysis showed that using a cut-off level of 14.57, MHR predicted the occurrence of primary end point with a sensitivity of 72% and specificity of 72%. In the multivariate model, high MHR was the only significant predictor of the primary end point. Conclusion: This study showed that higher MHR level is an independent predictor of malignant arrhythmia and death in patients with HCM.

Low-load resistance training combined with blood flow restriction (BFR) is known to result in muscle hypertrophy and strength similar to that observed with higher loads. However, the effects of resistance training with BFR on cardiac structure and cardiac function remain largely unknown. Therefore, the purpose of this randomized study was to compare the effects of conventional high-load resistance training (HL-RT) with the effects of low-load resistance training with BFR (LL-BFR) on muscle strength and left ventricular function. Sixteen young swimmers (mean ± standard deviation: age = 19.7 ± 1.6 years, body mass = 78.9 ± 9.7 kg, body height = 180.8 ± 5.8 cm) were randomly allocated to a conventional HL-RT group (n = 8) or a LL-BFR group (n = 8) with a pressure band (200 mmHg) placed on both thighs of participants for 4 weeks (3 days·week-1). Outcome measures were taken at baseline and after 4 weeks of training, and included body composition, one-repetition maximum (1RM) back squat, and echocardiography measures. The 1RM back squat significantly improved (partial eta squared (Ƞ2) = 0.365; p = 0.013) in HL-RT (mean difference (Δ) = 6.6 kg; [95% confidence interval (CI) −7.09 to 20.27]) and LL-BFR groups (Δ = 14.7 kg; [95% CI 3.39 to 26.10]), with no main effect of group or group × time interaction (p > 0.05). Interventricular septum end-systolic thickness showed a slight but statistically significant increase in LL-BFR and HL-RT groups (Ƞ2 = 0.253; p = 0.047), yet there was no main effect of group or group × time interaction (p > 0.05). There were no statistically significant changes (p > 0.05) in other cardiac structure or function parameters (e.g., left ventricular (LV) mass, LV cardiac output, LV ejection fraction, LV stroke volume) after the training programs. Results suggest that 4 weeks of HL-RT and LL-BFR improve muscle strength similarly with limited effects on left ventricular function in young swimmers.

Infective endocarditis (IE) is associated with increased mortality and morbidity. In this study, we aimed to evaluate the role of troponin levels in predicting long-term survival in patients with IE.A retrospective analysis of the medical database of Yuksek Ihtisas Education and Research Hospital was performed to reach the patients that received the diagnosis of definite IE according to Duke criteria. Out of 84 definite IE cases, 48 patients (mean age 45.6 ± 17.3, 39.6% female) that had troponin T levels measured upon hospital admission were included. The survival status of the study subjects was assessed during a follow-up period of 1 year.A total of 20 (41.7%) patients died during the follow-up. Baseline median troponin T levels were significantly higher in fatal cases (0.08 [0.02-0.24] ng/ml vs. 0.02 [0.01-0.04] ng/ml p = 0.003). The optimal troponin T level to detect mortality was 0.05 ng/ml according to receiver operating characteristic curve (area under the curve 0.75, 95% Confidence Interval (CI) [0.61-0.9], p = 0.003) with 70% sensitivity and 79% specificity. Patient with elevated troponin levels were older, were more likely to be male and tended to have enterococcal infection. These patients had also higher creatinine levels and increased systolic pulmonary pressures. In the multivariate Cox regression analysis, renal failure (hazards ratio (HR) 8.23, CI 95% 2.53-26.9, p < 0.0001), heart failure (HR 4.48, CI 95% 1.73-11.61, p = 0.002) and troponin T ≥ 0.05 ng/ml (HR 3.11, CI 95% 1.13-8.56, p = 0.03) were associated with increased mortality rates.IE has poor outcome and baseline troponin T levels may predict long-term survival rates in these patients.

Background: The importance of monocyte count-to-HDL-cholesterol ratio (MHR) in cardio- vascular diseases has been shown in various studies. Ascending aortic dilatation (AAD) is a common complication in the patients with bicuspid aortic valve. In this study, we aimed to investigate the relationship between MHR and the presence of aortic dilatation in the pa- tients with bicuspid aortic valve. Methods: The study population included totally 347 patients with bicuspid aortic valve.169 patients with aortic dilatation (ascending aorta diameter ≥ 4.0 cm) and 178 patients with no aortic dilatation. Echocardiographic and laboratory measure- ment was done and compared between groups. Results: The mean age of the participants was 44.7 ± 15.4 years and average ascending aorta diameter was 3.2 ± 0.3 cm in dilatation negative group and 4.4 ± 0.4 cm in positive group. MHR was significantly increased in in patients with aortic dilatation. MHR and uric acid level was independently associated with the presence of aortic dilatation in the patients with bicuspid aortic valve. Conclusion: We found a significant relationship between MHR and aortic dilatation in the patients with bicuspid aortic valve.
