In this study we aimed to investigate whether there is an association between the neutrophil lymphocyte ratio (NLR) and severity of coronary artery disease (CAD) in patients with non-ST segment elevation myocardial infarction (NSTEMI) using SYNTAX score (SXscore). A total 414 NSTEMI who underwent angiography were enrolled study. NLR was measured for all at presentation. The population then divided into 3 tertiles based on trial results.(1)) low syntax group (n = 329) defined as those SXscore...

We investigated the association between coronary artery ectasia (CAE) and Neutrophil-to-lymphocyte ratio (NLR), an indicator of inflammatory state. The study population included 434 patients (247 males, mean age 62 ± 10 years) including 230 with isolated CAE 104 disease 100 patientss normal arteries. NLR was measured at admission 30 days after angiography in all patients. significantly higher than those arteries (2.2 0.6-1.3 0.6, P < .001). Linear regression analyses revealed that...

Consecutive (n = 162) were randomized into 2 groups based whether was administered. After tirofiban, thrombolysis (TIMI) flow grade significantly increased ( P &lt; .001) and successful reperfusion achieved 26 (32%) patients.

Nonalcoholic steatohepatitis (NASH) is a part of histological spectrum nonalcoholic fatty liver disease (NAFLD). Higher incidence cardiovascular mortality has been reported in studies including patients with NAFLD. Impaired myocardial function can be detected by novel echocardiographic method called speckle tracking echocardiography (STE) when conventional methods were normal.Twenty-eight biopsy-proven NASH (mean age 41.6 ± 9.8, 16 male) without hypertension and diabetes mellitus included...

We investigated the predictors of endothelial dysfunction in patients with rheumatoid arthritis (RA) by brachial artery flow-mediated vasodilatation (FMD). The study population included 50 RA and 30 controls. Disease activity score (DAS28) was calculated for RA. An FMD response <7% accepted as impaired FMD. Brachial Doppler revealed that RA, FMD% significantly lower compared controls (6.6% ± 3.5% vs 9.7% 41%, P = .002). After multivariate logistic regression analysis, erythrocyte...

Echinococcosis is endemic in various regions of Turkey. Cardiac involvement echinococcosis rare, and lone cardiac hydatid cysts are even more unusual. Because disease can be fatal, asymptomatic patients optimally referred for surgical treatment. We present a rare case lone, primary, mobile cyst the left atrium 62-year-old woman. The caused dyspnea from ventricular inflow obstruction. In addition to reporting patient's fatal case, we discuss terms scant medical literature.
