It has been shown that speckle-tracking echocardiography (STE) is a feasible and reproducible method to assess left atrial (LA) function. The relationship between ventricular end-diastolic pressure (LVEDP) brain natriuretic peptide (BNP) with LA deformation parameters not studied comprehensively. Therefore, we propose investigate the effects of invasively obtained LVEDP BNP level on assessed by STE show them.The study population consisted 62 patients who underwent cardiac catheterization....

We investigated the relationship between baseline neutrophil-to-lymphocyte ratio (NLR) and contrast-induced nephropathy (CIN) in patients with ST-segment elevation myocardial infarction (STEMI). Consecutive diagnosed STEMI (n = 691) who underwent primary percutaneous coronary intervention (p-PCI) were included study. The CIN was defined as an increase serum creatinine concentration ≥25% over at 48 hours. Both NLR C-reactive protein levels significantly higher group. There a stronger...

No-reflow is associated with a poor prognosis in STEMI patients. There are many factors and mechanisms that contribute to the development of no-reflow, including age, reperfusion time, high thrombus burden, Killip class, long stent use, ejection fraction ≤40, Syntax score. In this study, we aimed evaluate parameters no-reflow prediction by creating new scoring system.The study included 515 consecutive patients who underwent PCI; 632 had undergone PCI another center were external validation...

Red cell distribution width (RDW) is an index that has been shown to be independent correlate of adverse outcomes in some cardiac conditions. Isolated coronary artery ectasia (CAE) abnormality the anatomy and can cause ischemia. We hypothesized increased RDW would associated with isolated CAE because both are inflammation.

Only a few studies focused on the predictors of SYNTAX score (SS). We evaluated independent clinical SS in 436 consecutive patients with stable angina pectoris who underwent coronary angiography. Estimated glomerular filtration rate (eGFR) was calculated. The mean 25.8 ± 13.7. High-sensitivity C-reactive protein and low-density lipoprotein cholesterol levels gradually rise while high-density (HDL-C), triglycerides, eGFR decline from low to high tertile.
