a 47 year-old female died after mitral valve replacement. post-cardiopulmonary bypass right ventricle was not able to pump despite good left ventricular contractility. at microscopic examination, diffuse right ventricular fatty infiltration was found. we found no previous report of this pathology in patients with mitral stenosis

background: echocardiography is the most common test used for the evaluation of aortic regurgitation (ar). however, the role of echocardiography as an available and inexpensive method in the quantification of ar by the left ventricle to right ventricle stroke volume ratio (lv/rv sv ratio) has not been completely investigated. methods: between june 2005 and december 2007, 132 consecutive patient...

A retrospective study was performed to elucidate the process of left ventricular aneurysm formation and its influence on left ventricular enlargement based on serial two-dimensional echocardiographic observations from 150 consecutive patients with first acute anterior myocardial infarction. Echocardiograms were available and interpretable through the entire period of observation in 68 patients....

Background and objectives: Resveratrol(3,5,4′-trihydroxy-trans-stilbene) is a natural polyphenole phytoalexin which exerts potential cardioprotective effects, but the cellular and molecular mechanisms responsible for these effects are still unknown. Cardiac renin angiotensin system (RAS) over-activation plays an important role in pathogenesis of left ventricula...

Background: There is conflicting data about prognostic implication of electrocardiographic (ECG) left ventricular hypertrophy (LVH) in patients with first non- ST-segment elevation myocardial infarction (NSTEMI). We aimed to examine the association of left ventricular hypertrophy (LVH) on admission electrocardiogram with adverse outcomes in patients with NSTEMI. Methods: In the present study, ...

Background: With the development of technology, human beings are increasingly under the exposure of Radio Frequency Radiation (RFR) (due to wireless technologies, mobile phones, base stations etc). The aim was to investigate the possible effects of Radio Frequency Radiation (RFR) on blood, aorta and heart tissue in hypertensive and non-hypertensive rats with various parameters. Materials and Me...
