The purpose of this study was to induce myocardial infarction (MI) and compare the echocardiographic parameters and mortality ratio of Lewis inbred and Wistar outbred strain before and after the procedure to help choose the best one for MI studies. In this study MI was induced in 46 Lewis and 34 Wistar by occlusion of left anterior descending artery (LAD). Doppler, two-dimensional (2-D) and 2-D...

Diabetes mellitus (DM) has been recognized as a major health problem. Emodin (Emo) has been reported to exhibit protective effects against diabetic nephropathy. However, little has been known about the effect of Emo on diabetic cardiomyopathy (DCM). A type 2 DM model was induced in rats by low dose streptozotocin (STZ) combined with high energy intake. We found that Emo-treated groups displayed...

The prognostic value of preoperative echocardiographic data was assessed in 32 patients who underwent aortic valve replacement for chronic aortic regurgitation. All patients had preoperative studies and were followed up prospectively for 1 to 6 years after surgery. Postoperatively, 25 patients (Group A) achieved a normal left ventricular end-diastolic dimension and a significant regression of m...

patients and methods forty five young female volunteer athletes were included and received different training regimens (endurance-training, strength training and concurrent groups) for a 10 week period as study intervention. standard color doppler echocardiography was performed for assessment of the left ventricular activity. results as a result, 45 athletes ended the study training regimens. m...

We have identified pericardial effusion by echocardiography in 174 patients. Seventeen had cardiac tamponade which was not always clinically obvious. Right ventricular narrowing or compression, occurring in the minor axis at end diastole and end expiration, to 7 +/- 2 mm or less, was strongly associated with tamponade in patients with effusion. Right ventricular compression and signs of tampona...

The acorn cardiac support device (ACSD) is a device designed to treat heart failure by containing the heart to prevent further dilation. Six patients with symptomatic heart failure due to ischemic cardiomyopathy were treated surgically with ACSD. All patients simultaneously underwent coronary artery bypass grafting. Ventricular reconstruction was also performed in 5 of the 6 patients. We follow...

introduction: the correlation between right and left ventricular ejection fractions (rvef and lvef, respectively) has been studied in only a small number of patients with a marked decrease in rvef and lvef. the aim of the present study was to compare lvef and rvef in patients with ischemic heart disease. rvef and lvef were measured by cardiovascular magnetic resonance (cmr) imaging. materials a...

Echocardiography was used to study left ventricular size and contraction in 90 patients with isolated mitral valve disease 47 patients with mitral stenosis, 26 with mixed mitral valve disease and 89 with mitral regurgitation. Left ventricular measurements included the end-diastolic internal dimension (LVIDd), mural thickness (PWTd), an index of circumferential myocardial contraction fractional ...

background: erythropoietin (epo) is known as a regulating hormone for the production of red blood cells, called erythropoiesis. some studies have shown that epo exerts some non-hematopoietic protective effects on ischemia-reperfusion injuries in myocytes. using echocardiography, we evaluated the effect of epo infusion on reducing ischemia-reperfusion injuries and improvement of the cardiac func...
