Abstract

High plasma levels of pro-inflammatory cytokines play an important role in the pathophysiology of congestive heart failure (CHF). Therefore, we conducted a case-control study to determine the correlations between plasma levels of cytokines, i.e., tumor necrosis factor-alpha (TNF-alpha) and interleukin (IL)-6, and the severity and mortality in patients with CHF. One-hundred and 18 cases (62+/-15 years old) were classified into 3 groups: group 1 comprised 44 control cases with normal coronary arteriogram and left ventriculography and without valvular disorders or cardiomyopathy; group 2 comprised of 37 cases with mild CHF in New York Heart Association (NYHA) functional class (FC) II; group 3 had 37 cases with moderate/severe CHF in NYHA FC III or IV. Pre-catheterization plasma levels of TNF-alpha and IL-6 along with clinical and hemodynamic variables and follow-up data of cardiac death were assessed. Patients of group 3 had smaller body mass index, lower systolic and diastolic blood pressures, faster heart rates, higher left ventricular end-diastolic pressure and lowered triglyceride levels than the patients of groups 1 and 2. The plasma levels of TNF-alpha and IL-6 increased significantly in patients of group 3 in comparison wit...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.
