BACKGROUND Detection of myocardial viability is important in patients with ischemic cardiomyopathy. Restoration of blood flow to viable myocardium is associated with improved left ventricular function and improved patient prognosis. However, the prevalence of viable myocardium in patients with ischemic cardiomyopathy is unknown. METHODS AND RESULTS To determine the prevalence of myocardial vi...

BACKGROUND In congestive heart failure (idiopathic dilated cardiomyopathy), exercise is accompanied by a smaller-than-normal decrease in end-diastolic left ventricular volume, depressed peak rates of left ventricular pressure rise and fall, and depressed heart-rate-dependent potentiation of contractility (bowditch treppe). We studied contractile function of isolated left ventricular myocardium ...

Background & Aims: One of the important aims of quantitative cardiac image processing is the clarification of myocardial motions in order to derive biomechanical behavior of the heart in the disease condition. In this study we presented a computerized analysis method for detecting the instantaneous myocardial changes by using 2D echocardiography images. Methods: The analysis was performed on th...

Diffusely increased glucose metabolic activity in the right and left ventricles using 2-deoxy-2-(F-18) fluoro-D-glucose positron emission tomography/computed tomography (18F-FDGPET/CT) and global left ventricular hypokinesia at echocardiography can be evident in acute myocarditis. But, there has been no case report that the ventricular 18F-FDGuptake remains unchanged even ...

recognition of the natural history and responsible leading factors for regression of left ventricular hypertrophy after successful renal transplantation are very important. the aim of this study was to assess the regression of left ventricular hypertrophy after successful renal transplantation among uremic patients. in this study 27 uremic patients (18 males and 9 females) with an average age o...

We analyzed data from 68 consecutive patients with congestive cardiomyopathy to evaluate the prognostic significance of quantitative morphologic findings in left ventricular myocardium as compared with the prognostic significance of left ventricular hemodynamics. Left ventricular endomyocardial biopsy specimens were obtained from all patients during diagnostic heart catheterization. Myocardial ...

Transient post ischemic left ventricular dysfunction has been called stunned myocardium. The stunned myocardium can lead cardiac problems such as arrhythmias, left ventricular dysfunction, and a myocardial infarction. Stunned myocardium is a reversible condition. In this case, a 25 year old female patient with a history of mild intermittent asthma became hypovolemic and got into shock after dev...
