The aim of this study was to evaluate the relationship between hematologic indices and the Global Registry of Acute Coronary Events (GRACE) score in patients with ST-segment elevation myocardial infarction (STEMI). A total of 800 patients who consecutively and retrospectively presented with STEMI within 12 hours of symptom onset. After accounting for exclusion criteria, a total of 379 patients remained in the study. We enrolled 379 patients with STEMI (mean age 61.7 ± 13.6 years; men 73%). Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), red cell distribution width (RDW), and monocyte count were associated with increased worse GRACE risk score (P = .008, P = .012, P = .005, P = .022, respectively). In multivariate linear regression analysis, NLR, PLR, RDW, and monocyte count were found to be independent predictors of GRACE risk score. We demonstrate for the first time that PLR, RDW, and monocyte were associated with the GRACE score in patients with STEMI.

In patients with unstable angina pectoris (UAP) or non-ST elevation myocardial infarction (NSTEMI), long-term mortality remains high despite improvements in the diagnosis and treatment. In this study, we investigated whether serum albumin level is a useful predictor of long-term mortality in patients with UAP/NSTEMI. Consecutive patients (n = 403) who were hospitalized with a diagnosis of UAP/NSTEMI were included in the study. Patients were divided into 2 groups based on the presence of hypoalbuminemia and the relationship between hypoalbuminemia and mortality was analyzed. Hypoalbuminemia was detected in 34% of the patients. The median follow-up period was 35 months (up to 45 months). Long-term mortality rate was 32% in the hypoalbuminemia group and 8.6% in the group with normal serum albumin levels ( P < .001). On multivariate analysis, hypoalbuminemia, decreased left ventricular ejection fraction, and increased age were found to be independent predictors of mortality ( P < .05). The cutoff value of 3.10 g/dL for serum albumin predicted mortality with a sensitivity of 74% and specificity of 67% (receiver-operating characteristic area under curve: 0.753, 95% CI: 0.685-0.822). All-cause long-term mortality rates were significantly increased in patients with hypoalbuminemia. On-admission albumin level was an independent predictor of mortality in patients with UAP/NSTEMI.

IntroductionThe thrombolysis in myocardial infarction (TIMI) risk score is calculated as the sum of independent predictors of mortality and ischemic events in ST elevation acute myocardial infarction (STEMI). Several studies show that the neutrophil to lymphocyte ratio (NLR) is a prognostic inflammatory marker. In preliminary studies, platelet to lymphocyte ratio (PLR) has been proposed as a pro-thrombotic marker. The relationship between NLR, PLR and TIMI risk score for STEMI has never been studied.AimTo evaluate the association between TIMI-STEMI risk score and NLR, PLR and other biochemical indices in STEMI.Material and methodsIn this retrospective study, we evaluated 390 patients who presented with STEMI within 12 h of symptom onset. Patients were grouped according to low and high TIMI risk scores.ResultsWe enrolled 390 patients (mean age 61.9 ±13.6 years; 73% were men). The NLR, platelet distribution width (PDW) and uric acid level (UA) were significantly associated with a high TIMI-STEMI risk score (p = 0.016, p = 0.008, p = 0.030, respectively), but PLR was not associated with a high TIMI-STEMI risk score. Left ventricular ejection fraction was an independent predictor of TIMI-STEMI risk score. A cut-off point of TIMI-STEMI score of > 4 predicted in-hospital mortality (sensitivity 75%, specificity 70%, p < 0.001). We found that NLR, PDW, and UA level were associated with TIMI-STEMI risk score.ConclusionsNeutrophil to lymphocyte ratio, PDW and UA level are convenient, inexpensive and reproducible biomarkers for STEMI prognosis before primary angioplasty when these indicators are combined with the TIMI-STEMI risk score. We believe that these significant findings can guide further clinical practice.

CAD is the leading cause of morbidity and mortality in the general population. Inflammation, endothelial damage and dysfunction, genetic predisposition and immune activation play key roles in the development of atherosclerotic vascular disease. 1 Inflammatory cells at the site of the atherosclerotic lesion have an important pathophysiological role in plaque rupture. 2 ACS includes unstable angina pectoris, NSTEMI and STEMI. 3 Recently, WBC count and its subtypes are accepted as markers of inflammation in cardiovascular diseases. [4][5][6] A novel systemic inflammatory marker, LMR, lymphocyte count divided by monocyte count, has been recently studied in infectious and autoimmune diseases, cancer patients and cardiovascular illnesses.

Background Recent findings indicate that thrombosis is one of the underlying pathophysiology and complication of COVID‐19 infection. Therefore, the prognosis of the disease may be more favourable in people who were under oral anticoagulant treatment before the COVID‐19 diagnosis. This study aims to evaluate the effects of chronic DOAC use on ICU admission and mortality in hospitalized patients due to COVID‐19 infection. Method Between 1 September and 30 November 2020, 2760 patients hospitalized in our hospital due to COVID‐19 were screened. A total of 1710 patients who met the inclusion criteria were included in the study. The patients were divided into two groups as those who use DOAC due to any cardiovascular disease before the COVID‐19 infection and those who do not. Results Seventy‐nine patients were enrolled in the DOAC group and 1631 patients in the non‐DOAC group. Median age of all study patient was 62 (52‐71 IQR) and 860 (50.5%) of them were female. The need for intensive care, in‐hospital stay, and mechanical ventilation were observed at higher rates in the DOAC group. Mortality was observed in 23 patients (29%) in the DOAC group, and it was statistically higher in the DOAC group ( P = .002). In the multivariable analysis, age (OR: 1.047, CI: 1.02‐1.06, P < .001), male gender (OR: 1.8, CI: 1.3‐2.7, P = .02), lymphocyte count (OR: 0.45, CI: 0.30‐0.69, P < .001), procalcitonin (OR: 1.12, CI: 1.02‐1.23, P = .015), SaO 2 (OR: 0.8, CI: 0.77‐0.82, P < .001) and creatinine (OR: 2.59, CI: 1.3‐5.1, P = .006) were found to be associated with in‐hospital mortality. DOAC treatment was not found to be associated with lower in‐hospital mortality in multivariable analysis (OR:1.17, CI: 0.20‐6.60, P = .850). Conclusion Our study showed that the use of DOAC prior to hospitalization had no protective effect on in‐hospital mortality and intensive care need in hospitalized COVID‐19 patients.
