Follow-up study in congestive (dilated) cardiomyopathy

Abstract

A follow-up study was carried out in 98 patients with congestive cardiomyopathy using clinical data and M-mode echocardiography. 59 patients survived (mean follow-up period 18 months), 39 patients died (mean survival period 12.6 months). Median survival time was 3 years. Prognosis was unfavorably affected by ECG signs (left bundle branch block, atrial fibrillation, ventricular premature beats), functional class 4, and left ventricular dysfunction presented by mitral E-point separation over 25 mm, left atrial dimension of 50 mm or more and posterior wall systolic thickening less than 50%. Age, excessive alcohol intake, left ventricular enddiastolic dimension or wall thickness did not affect prognosis. M-mode restudies preformed in 59 patients included a variable course within 2 years after first presentation but a progressive impairment of left ventricular function in mor than 2 years of follow-up.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

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.
