background: acute myocardial infarction (ami) is the leading cause of disability and death in iran and many other countries. objective: to investigate the prognostic value of ccl5 and ccl18 in patients with acute myocardial ischemia. methods: in this cohort study we recruited and followed 50 patients with acute anterior myocardial infarction (aami) for developing cardiovascular accidents in a 6...

The most advanced scientific development of biometrics will be to uniquely identify an individual based on their clinically used cardiac physiological and anatomical attributes. Research studies have demonstrated in particular the potential of cardiovascular activity as a biometric marker. Electrocardiogram (ECG) signals and left ventricular Ejection Fraction (EF) measured via echocardiography ...

Interrelationships among left ventricular (LV) size, LV function, and heart size were investigated in 49 patients studied 2-12 months after myocardial infarction. LV end-diastolic volume (EDV) and ejection fraction (EF) were determined by biplane ventriculography. Heart size was estimated from chest films by the cardiothoracic ratio (CTR) and cardiac volume (CV) methods. Ventricular function (i...

background: bone marrow-derived mesenchymal cellscan transdifferentiate into cardiomyocyte cells and improveheart function after transplantation. since biomaterials canimprove the cell retention in the site, cell survival and differentiation,heart tissue engineering is now being explored as anapplied solution to support cell-based therapies and increasetheir efficacy for myocardial diseases. ch...

INTRODUCTION Implantation of an aortic-bifemoral prosthesis is characterised by a high (> 5%) rate of perioperative cardiovascular events. The main aim of the study is to demonstrate the usefulness of the determination of NT-proBNP concentration as a method of risk stratification of left ventricular dysfunction in patients subjected to surgery for aortic-bifemoral prosthesis implantation. MAT...

As described in the study by Smith et al. (1) published in this issue of the Journal, the syndrome of “heart failure with a preserved ejection fraction” includes patients admitted to the hospital with symptoms and signs of heart failure (HF), radiographic evidence of HF, and an ejection fraction (EF) 40%. Approximately one-half of the consecutively enrolled patients with HF had an EF 40%, indic...

Background Manual planimetry for quantitative analysis of ejection fraction (EF) and infarct size (IS) on cardiac magnetic resonance (CMR) imaging are too time-consuming, and therefore, impractical in daily clinical practice. We sought to derive and examine the predictive accuracy of a semi-quantitative scoring technique to screen patients with an EF ≤35% or an IS ≥18.5%, known independent pred...

Background Left ventricular (LV) parameters may vary with aging, but concomitant disease can obscure relationships between age and LV size, mass and function. CMR provides reproducible measures of LV volumes, mass, and ejection fraction (EF), but manual analyses are time consuming. Automated border detection (ABD) methods may decrease analytical burden. We sought to examine the effect of greate...

Background The advantage in predictive value of coronary artery bypass surgery (CABG), as the therapeutic treatment in patients with coronary artery disease with low left ventricle ejection fraction (EF) is well known. Influence of abnormal segmental wall motion on the reduction of EF is well known. However, it is not quite clear, what is the relation between abnormal segmental wall motion and ...
