Abstract

It has been suggested that various factors related to dilated cardiomyopathy (DCM) may concern its onset and/or progression. This study was performed to clarify whether these factors contribute different clinical and morphological characteristics. Subjects were 39 patients with DCM, consisting of 28 men and 11 women whose average age was 46.5 years. The subjects were divided into five groups; namely, the Familial, Myocarditic, Alcoholic, Hypertensive, and Unknown Groups. Clinical parameters including past history, blood pressure, chest radiographs, electrocardiograms, echocardiograms and left ventricular end-diastolic pressures (LVEDP) were evaluated. Morphology of right ventricular endomyocardial biopsy specimens was evaluated in terms of hypertrophy, disarrangement, fibrosis, degeneration, endocardial thickening, interstitial changes, and types of fibrosis. The results were as follows: The Familial Group was characterized by the onset at younger age, highly elevated LVEDP, a lack of myocardial hypertrophy, and proliferation of small vessels. The Myocarditic Group was characterized by the onset at young age, elevated LVEDP, severe fibrosis showing a plexiform pattern in more than half of the patients, cellular disarrangement, ...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
