To determine the effects of moderate ethanol consumption on the mechanical, biochemical, and structural characteristics of the heart, myocardial mechanical performance, contractile protein enzyme activity, and the number and size of myocytes were measured in male Fischer 344 rats after the ingestion of 30%o oral ethanol. Papillary muscles removed from the left ventricle were greater in length, ...

BACKGROUND AND METHOD Asymmetric distribution of histologic lesions have been reported in grafted hearts that could hamper the interpretation of right ventricular endomyocardial biopsy. Heterotopic heart transplantations were performed in rats (n=59) and guinea pigs (n=20). Grafted hearts were examined by a pathologist who established the degree of cardiac rejection in the four cardiac cavities...

The heart is frequently the site of metastasis of various malignant tumors. Lung cancer is one of the most common primary tumors of cardiac metastasis and usually involves the pericardium or epicardium by direct invasion and/or lymphatic spread. However, metastasis of lung cancer involving the left ventricular endocardium is extremely rare. We report a patient with adenocarcinoma of lung, metas...

Dear Editor, Non-compaction cardiomyopathy (NCC) is an unclassified cardiomyopathy, previously known as “spongy left ventricular myocardium”. It is characterised by prominent myocardial trabeculations and deep intertrabecular recesses which lie in continuity with the left ventricular cavity. This failure in the normal compaction of the ventricular endomyocardium results from an arrest in cardia...

Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is a cardiac muscle disorder characterized pathologically by fibrofatty replacement of the right ventricular (RV) myocardium [1]. In the early stage of the disease, structural changes may be confined to, the so called "triangle of dysplasia" in the RV. Clinical expression ranges from an asymptomatic phenotype, arrhythmias or eve...

performance of heart has substantial role in breaking records of sports. achieving to optimal performance of endurance training builds upon the consistency in several parts of body specially heart. type, intensity, term training programs is determining components of providing structural consistency and performance of heart especially in left ventricular. aim of this research was comparing struc...

takotsubo cardiomypathy is a very rare cardiovascular syndrome leading to myocardial infarction and left ventricular dysfunction in the absence of a detectable coronary artery lesion. it is accepted as reversible left ventricular asynergy occuring typically after an intrinsic adrenergic hyperstimulation. in this report we present takotsubo cardiomyopathy in a 75-year-old patient with multiple a...

background: n-terminal pro-brain natriuretic peptide (nt-probnp) is a sensitive biomarker for the detection of asymptomatic left ventricular (lv) dysfunction. since β-thalassemia major patients suffer from early diastolic dysfunction due to iron deposition of chronic blood transfusion, we tried to evaluate the correlation between the serum nt-probnp level and the severity of lv diastolic dysfun...
