High SYNTAX score is a predictor of adverse cardiovascular events, including mortality, in acute coronary syndromes (ACSs). Decreased serum albumin (SA) concentration associated with an increased risk events. We aimed to investigate whether SA levels at admission are high and in-hospital mortality patients ACS. The study included 1303 ACS who underwent angiography (CA). were divided into 2 groups as (≥33) lower (≤32). Baseline significantly than (3.46 ± 0.42 mg/dL vs 3.97±0.37 mg/dL,...
High sensitive C-reactive protein (hs-CRP) levels are associated with short- and long-term mortality in patients acute coronary syndrome (ACS). We investigated whether baseline hs-CRP burden of atherosclerosis assessed by SYNTAX score (SXScore).We enrolled 321 ACS who underwent angiography. The were divided into tertiles according to the SXScore: low SXScore (≤ 22), intermediate-high (≥ 23).Subjects tertile had higher serum compare (7.7 ± 3.4 mg/L versus 4.9 2.5 mg/L, P < 0.001). mean age...
Background Recently, it has been shown that the lymphocyte-to-monocyte ratio (LMR) is a novel inflammatory marker. A decreased LMR associated significantly with high risk for vascular endpoints in patients peripheral arterial disease. We aimed to investigate whether on admission no-reflow after primary percutaneous coronary intervention (PCI) ST-elevation myocardial infarction (STEMI). Patients and methods total of 857 (mean age 58.9±13.1 years, 75.6% men), who were admitted our hospital...

High Syntax score (SXscore) is associated with more serious disease and worse prognosis in patients acute coronary syndrome (ACS). Plasma fibrinogen levels are poor cardiovascular outcomes.To investigate the relation of admission intermediate-high SXscore ACS.A total 752 (61.6 ± 12.8 years, 67.3% men) ACS, who underwent urgent angiography (CAG) were enrolled. Laboratory data including high sensitivity C-reactive protein obtained before CAG. scores all calculated from baseline The divided...
Aim: A lower lymphocyte count and a high monocyte give important clues about the prognosis of various cardiovascular diseases. We hypothesized that lymphocyte-to-monocyte ratio (LMR) was associated with saphenous vein graft disease (SVGD) in patients coronary artery bypass (CABG). Patients & methods: total 218 previous history CABG surgery, who underwent angiography due to stable angina symptoms, were investigated, retrospectively. Results: LMR levels significantly SVGD group. Multiple...
Hyperhomocysteinemia is a known risk factor for acute coronary syndrome (ACS) and related with the severity of artery disease (CAD). Previous studies have used less quantifiable scoring systems assessing CAD. Therefore, we aimed to assess relationship between homocysteine levels SYNTAX score (SXscore), which currently more widely grade CAD.A total 503 patients adiagnosis ACS were examined angiographically SXscore. The divided into three groups according SXscore; Group 1 low SXscore (≤ 22), 2...
