The evolution of left ventricular dysfunction in 36 patients with coronary artery disease and no interim surgical intervention was studied over a mean interval of 26 months (range 6-71 months). The ejection fraction decreased 0.08 (p < 0.001) on the average in patients with coronary artery disease progression. However, progression of coronary artery disease was not accompanied by a decrease in ...

OBJECTIVE To report a case of severe vasospasm after subarachnoid haemorrhage (SAH) where "tissue at risk" was identified by magnetic resonance imaging (MRI), and to demonstrate the haemodynamic consequences with either resolution of the perfusion-diffusion mismatch by balloon angioplasty or evolution of an infarct. METHODS A 45 year old women with SAH underwent surgical treatment of a ruptur...

Electrocardiograph-gated blood pool scans (anteroposterior and left anterior oblique projections) were recorded in 30 patients seven to 10 days after myocardial infarction. Left ventricular ejection fractions (mean 0.26 +/- 0.10) were lower on average than values previously obtained in 11 normal subjects (mean 0.52 +/- 0.06) and correlated broadly with the clinical assessment of left ventricula...

The present study investigated the effect of using PRAAT as a free computer software package for the scientific analysis of speech in phonetics on pre-intermediate Iranian English as foreign language (EFL) learners’ supra segmental features (i.e., intonation and stress). The design of the study was a Quasi-experimental research design with a pre and post-test. In doing so...

OBJECTIVES Left ventricular remodeling after acute myocardial infarction increases cardiovascular events and mortality. But few study was done in patients with preserved ejection fraction (EF > 40%). We investigate whether the strain and strain rate by 2D speckle tracking echocardiography could predict left ventricular remodeling after acute myocardial infarction in this cohort. METHODS The 8...

background: primary focal segmental glomerulosclerosis (fsgs) is defined by the presence of proteinuria, often in nephrotic range and pathologically by segmental scars (ss). the aim of this study is to identify the possible predictors of complete remission or progression to chronic kidney disease in iranian adults with primary focal segmental glomerulosclerosis. methods: in this historical coho...

BACKGROUND Diagnosing a postoperative myocardial infarction in patients undergoing coronary artery bypass grafting is challenging, as the normally used criteria are more difficult to interpret. The rate of implementation of the consensus-based new diagnostic criteria for postoperative myocardial infarction proposed by the third universal definition of myocardial infarction is unknown. Therefore...

The ongoing inflammatory process in COVID infection is reported to cause acute cardiac injury either due direct cytotoxicity or oxidative stress myocytes. Hypercoagulability and endothelial dysfunction are the two main events resulting transient thrombotic process. Objective: To assess coronary artery occlusion infected patients presenting with ST-elevation myocardial injury. Methods: A descrip...

Myocardial infarction (MI) results in a dense scar region surrounded by heterogeneous remodeled border zone. In this denervation and nerve regeneration during healing could be dependent contribute to segmental differences the functional substrate for arrhythmias. To examine regional electrophysiological remodeling relation perfusion innervation changes after myocardial infarction. Anterio-septa...
