BACKGROUND Recent progress has been made in the understanding of the cellular and molecular mechanisms of growth hormone action and of its effects on cardiac tissue. The aim of this study was to measure growth hormone concentrations, along with various other hormones, in patients with stable chronic congestive heart failure due to idiopathic dilated cardiomyopathy. METHODS The study included 23 ambulatory men, 51.2+/-9.3 years of age, on standard medical therapy for heart failure due to idiopathic dilated cardiomyopathy. All patients underwent clinical and laboratory evaluations, including echocardiogram, radionuclide ventriculography, right heart catheterization, coronary angiography, and right ventricular endomyocardial biopsy. Serum or plasma concentrations of growth, thyroid, sex and adrenal hormones were measured in all patients and compared with those found in 20 age-matched healthy men. RESULTS Growth hormone, insulin-like growth factor I, and free testosterone values in patients with idiopathic dilated cardiomyopathy and heart failure were 0.37+/-0.2 ng/ml, 123.7+/-50 ng/ml and 48.6+/-23.8 pmol/l, respectively, versus 0.5+/-0.4 ng/ml (P<0.01), 236.3+/-66.4 ng/ml (P<0.001) and 105+/-17 pmol/l (P<0.01), respectively, in the healthy age-matched individuals. All other hormone concentrations were comparable in both groups. CONCLUSIONS Chronic heart failure due to idiopathic dilated cardiomyopathy is associated with a significant decrease in growth hormone, insulin-like growth factor I, and testosterone concentrations, probably due to chronic disease.

UI MeSH Term Description Entries
D007334 Insulin-Like Growth Factor I A well-characterized basic peptide believed to be secreted by the liver and to circulate in the blood. It has growth-regulating, insulin-like, and mitogenic activities. This growth factor has a major, but not absolute, dependence on GROWTH HORMONE. It is believed to be mainly active in adults in contrast to INSULIN-LIKE GROWTH FACTOR II, which is a major fetal growth factor.

D011336 Probability The study of chance processes or the relative frequency characterizing a chance process. Probabilities
D011379 Prognosis A prediction of the probable outcome of a disease based on a individual's condition and the usual course of the disease as seen in similar situations. Prognostic Factor,Prognostic Factors,Factor, Prognostic,Factors, Prognostic,Prognoses
D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation. Radioimmunoassays

D002311 Cardiomyopathy, Dilated A form of CARDIAC MUSCLE disease that is characterized by ventricular dilation, VENTRICULAR DYSFUNCTION, and HEART FAILURE. Risk factors include SMOKING; ALCOHOL DRINKING; HYPERTENSION; INFECTION; PREGNANCY; and mutations in the LMNA gene encoding LAMIN TYPE A, a NUCLEAR LAMINA protein.

D006333 Heart Failure A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
