Endocan is a soluble proteoglycan, secreted by human vascular endothelial cells. Endocan is a marker for vascular pathologies and an important mediator of angiogenesis, strongly associated with inflammation, vascular endothelial dysfunction, and atherosclerosis. The relationship between coronary artery ectasia (CAE) and endocan has not been evaluated. We aimed to investigate this association. Fifty-four patients with isolated CAE without coronary stenosis and 30 controls with normal coronary angiogram were included in this study. Endocan plasma concentrations were measured using an enzyme-linked immunosorbent assay. Patients with isolated CAE had significantly higher levels of endocan compared to the controls (18.9 ± 7.3 vs 15.6 ± 3.6 ng/mL; P = .007). There was a significant correlation between endocan levels and severity of isolated CAE according to the Markis classification ( r = -.593, P < .001). Plasma endocan levels may reflect the presence and severity of isolated CAE, suggesting that endocan may be involved in pathogenesis of isolated CAE.

High SS which was obtained through diagnostic angiogram of PPCI may be associated with LVT development in patients with first anterior wall STEMI.

Objective: The aim of the present study was to investigate the association between nitrate-induced headache (NIH) and the complexity of coronary artery lesions in patients with stable coronary artery disease (CAD). Subjects and Methods: Two hundred and seventy-five patients with anginal chest pain who underwent coronary angiography were enrolled in the present study. NIH was defined as the presence of headache due to nitrate treatment (isosorbide mononitrate 40 mg) after excluding confounding factors. Coronary artery lesion complexity was assessed by the SYNTAX score (SXscore) using a dedicated computer software system. Results: The mean SXscore was lower in the patients with NIH than in patients without NIH (7.3 ± 5.2 vs. 14.4 ± 8.5, respectively; p < 0.001). Additionally, patients with NIH had a lower rate of multivessel disease compared with those without NIH (the mean number of diseased vessels was 1.5 ± 0.7 and 2.0 ± 07, respectively; p < 0.001). In multivariate analysis, increasing age (p = 0.02) and headache (p = 0.001) were found to be independent determinants of SXscore. Conclusion: The present study demonstrated an independent inverse association between NIH and SXscore. The NIH could provide important predictive information about coronary artery lesion complexity in patients with stable CAD.

Left ventricular thrombus (LVT) is associated with inflammatory response in survivors with anterior ST-elevation myocardial infarction (STEMI). The C-reactive protein to albumin ratio (CAR) has been proposed as a marker of inflammation. However, there is a lack of data with respect to the role of CAR in LVT development. We investigated the relationship between CAR and LVT development in patients with anterior STEMI treated percutaneously; 955 consecutive patients were enrolled and LVT was observed in 126 (13.2%) patients. Clinical, demographic, and laboratory parameters were recorded. The CAR was significantly higher in patients with LVT (12.6 [8.6-16.1] vs 18.1 [11.5-23], P < .001). Other independent predictors for LVT development were lower ejection fraction, the presence of left ventricular apical aneurysm, proximal left anterior descending lesion location, glycoprotein IIb/IIIa inhibitors treatment, >1 diseased arteries, higher total protein level, neutrophil count, and peak creatine kinase myocardial band activity. In conclusion, the CAR may be useful as a simple tool for predicting LVT development among survivors of anterior STEMI.

in the setting of ACS is associated with poor clinical course and prognosis of the disease. Also, new-onset atrial fibrillation (NOAF) in the setting of percutaneously treated ACS has been reported with increased in-hospital and long-term mortality (Rene et al., 2014;Ruwald et al., 2013). Especially, patients with NOAF, who were not diagnosed as AF before the ACS associated with higher mortality rates compared with those ACS patients who were admitted with
