Pulmonary embolism (PE) is associated with significant morbidity and mortality. New biological markers are being investigated for estimating the prognosis of PE patients. Since PE is closely associated with inflammatory status, the neutrophil-lymphocyte (NLR), platelet-lymphocyte (PLR), and lymphocyte-monocyte (LMR) ratios were suggested to be useful in predicting patient outcomes. This study aimed to evaluate the prognostic role of NLR, PLR, and LMR in PE. A total of 103 PE cases from a cardiology department were included in the study. Control group consisted of 102 patients selected from outpatient clinics other than cardiology, cardiovascular surgery, and chest diseases. We retrospectively evaluated demographic and clinical characteristics, treatments, laboratory and imaging findings, and outcomes of patients. The median follow-up of PE patients was 39 months, and the 5-year overall survival probability was 73.8%. Out of 103 patients, 20 were classified as high risk PE cases (19.4%). Thrombolytic treatment was administered to 23 patients (22.3%). Systolic pulmonary arterial pressure was measured during one year, showing a significant decrease from 51.7 ± 15.7 mmHg at admission to 26.6 ± 4.0 mmHg at first year assessment. Age (OR: 1.06, p < 0.001) and NLR (OR: 1.52, p < 0.0019) were significantly associated with the disease status. The independent prognostic factors in moderate-low and low risk PE groups were NLR (HR: 1.17, p = 0.033) and LMR (HR: 1.58, p = 0.046). In moderate-high and high risk PE patients, the independent prognostic factors were age (HR: 1.07, p = 0.014) and PLR (HR: 1.01, p = 0.046). NLR, PLR, and LMR were associated with the prognosis of PE patients. The clinical severity of PE should be considered when utilizing these markers to assess patient outcomes.

Carotid artery stenosis (CAS), mainly caused by carotid atherosclerosis, is related to ischemic stroke. We investigated whether C-reactive protein (CRP) to albumin ratio (CAR) was associated with increased severity of carotid stenosis in patients undergoing carotid angiography. A total of 269 patients who were undergoing carotid angiography were included in this study. The patients were divided into 2 groups with respect to the severe CAS: group 1 (stenosis < 70%, n = 189) or group II (stenosis ≥ 70%, n = 80). C-reactive protein to albumin ratio was higher in group II compared to group I (0.56 ± 0.25 vs 0.14 ± 0.01, P < .001). The CAR (odds ratio [OR]: 1.051, 95%CI: 1.027-1.076, P < .001), neutrophil to lymphocyte ratio (NLR), and total cholesterol levels were independent predictors of severe CAS. The area under the receiver operating characteristic curve (area under the curve) for the CAR to predict severe CAS was 0.798 (95% CI: 0.741-0.854, P < .001). C-reactive to protein albumin ratio was an independent risk factor of severe CAS. Therefore, CAR might be considered a potential index in the severity of carotid artery disease.

Nutritional status and its index (Prognostic Nutritional Index, PNI) is an important prognostic factor for ST-segment elevation myocardial infarction (STEMI). The present study investigated whether PNI it is associated with no-reflow in patients with STEMI. In this retrospective study, 404 patients with STEMI and underwent primary percutaneous coronary intervention (pPCI) were consecutively included, between January 2016 and December 2018. No-reflow phenomenon (NRP) was detected in 103 (25.4%) patients. In multivariate logistic regression analysis C-reactive protein (CRP) (odds ratio (OR): 1.693, 95% confidence interval (CI): 1.126–2.547, P = .011), left ventricle ejection fraction (LVEF) (OR: 0.777, 95% CI: 0.678–0.891, P < .001), SYNTAX score (OR: 1.114, 95% CI: 1.050–1.183, P = .001), low density lipoprotein cholesterol (LDL-C) (OR: 1.033, 95% CI: 1.013–1.055, P = .002), hemoglobin level (OR: 0.572, 95% CI: 0.395–0.827, P = .003), PNI (OR: 0.554, 95% CI: 0.448–0.686, P < .001) were associated with NRP. The area under curve of PNI was significantly higher than albumin (z = 4.747, P < .001) and lymphocyte values (z = 3.481 P < .001). PNI was associated with no-reflow occurrence and mortality. So, PNI may be useful to predict NRP risk in patients with STEMI before pPCI.

Ascending aortic aneurysms are one of the major causes of mortality. In recent years, there is a growing interest of epicardial adipose tissue (EAT) and related diseases. The aim of this study was to investigate the relationship of EAT, and PAT with ascending aortic dilatation (AAD). We included 934 patients with hypertension in this study. The patients were evaluated by a complete transthoracic echocardiographic examination, including measurements of EAT, PAT, and aortic dimensions. Aortic size index (ASI) was used for diagnosing AAD. The patients were divided into two groups: dilated ascending aorta diameter (ASI ≥ 21 mm / m2, n = 102) or normal aortic diameter (ASI < 21 mm / m2, n = 832) according to the ASI. Characteristics of these patients were compared before and after propensity score matching analysis. Patients with AAD were older (72.3 ± 11.6 vs. 61.7 ± 12.7 years, p < 0.001), had more female gender (66% vs. 54%,p = 0.021) than patients with normal ascending aorta (AA). After propensity score matching analysis (77 vs. 77), EAT [OR:1.461, %95CI (1.082–1.974), p = 0.013] was independently associated with AAD in multivariate logistic regression analysis. In ROC curve analysis, EAT > 0.45 cm had 51.9% sensitivity and 62.3% specificity [AUC = 0.617, P = 0.012, 95% CI (0.529–0.707)]. Based on our findings, increased EAT may be suggested as an independent risk factor for AAD due to local or systemic effects in hypertensive patients.

Background and Objectives: The aim of this study was to investigate the prognostic value of soluble ST2 (sST2) in predicting postoperative adverse events in patients with impaired left ventricular (LV) function undergoing coronary artery bypass graft (CABG) surgery. Materials and Methods: This study included 80 consecutive patients with stable coronary artery disease (CAD) and impaired LV function (ejection fraction ≤ 45%) undergoing on-pump coronary artery bypass graft surgery. The patients were divided into the “high” or “low” group according to their ST2 levels (≥35 or <35 ng/mL). Results: Postoperative adverse events were more common in patients with high sST2 levels than in patients with low sST2 levels (100% vs 26%, p < 0.0001). Multivariate analysis showed that sST2 level was an independent predictor of the presence of postoperative adverse events (OR: 1.117 (95% CI: 1.016–1.228), p = 0.022). The receiver operating characteristic curve (ROC) analysis of sST2 revealed an area under the curve (AUC) of 0.812 (95% CI: 0.710–0.913, p < 0.001) in predicting postoperative adverse events. An sST2 level of 26.50 ng/ml was identified as the optimal cut-off value, with a sensitivity and specificity of 74.1% and 75.3%, respectively. Conclusion: Higher sST2 levels were associated with adverse outcomes after CABG in patients with impaired LV and stable CAD.

Background: Ascending aortic aneurysms are one of the primary causes of mortality. However, not much is known about the etiologies of aortic aneurysm. Recently, in hypertensive (HT) patients, blood pressure variability (BPV) has been recommended as a remarkable risk factor for adverse cardiovascular outcomes. This study aimed to explore the association between short-term BPV and ascending aortic dilatation (AAD). Methods: In this study, a total of 53 HT patients with AAD (aortic size index [ASI] ≥21 mm/m2) and 126 HT patients with a normal ascending aortic diameter (ASI <21 mm/m2) were included. Baseline, echocardiographic, and 24-h ambulatory blood pressure (BP) monitoring results were compared between groups. Standard deviation (SD) and coefficient of variation (CV) of BP were used to determine short-term BPV. Results: Except for daytime SBP values, daytime, nighttime, and 24-h mean systolic (SBP) and diastolic (DBP) BP levels were similar between groups. Compared with the HT patients with normal AA, daytime SBP, daytime SD of SBP, 24-h SD of SBP, daytime CV of SBP, and 24-h CV of SBP were significantly higher in HT patients with AAD. Compared with the HT patients with normal AA, the frequency of nondipper pattern was higher and dipper pattern was lower in HT patients with AAD. In multivariate logistic regression analysis, the daytime CV of SBP, daytime SD of SBP, 24-h SD of SBP, daytime SBP, and left ventricular mass index were independently associated with AAD. In receiver operating characteristic curve analysis, the daytime CV of SBP levels of >12.95 had a sensitivity of 61% and a specificity of 59% (area under the curve, 0.659; 95% CI, 0.562–0.756; P= .01); moreover, daytime SD of SBP > 16.4 had sensitivity of 62% and specificity of 61% (AUC, 0.687; 95% CI, 0.591–0.782; P< .001). :Conclusion Increased short-term BPV is independently associated with AAD and may be recommended as a remarkable factor risk for AAD in HT patients.
