Blood Content of Markers of Inflammation and Cytokines in Patients With Alcoholic Cardiomyopathy and Ischemic Heart Disease at Various Stages of Heart Failure

We conducted a comparative study of content proinflammatory cytokines, biomarkers of inflammatory process, biochemical indicators of congestive heart failure (CHF) and hemodynamic parameters in patients with alcoholic cardiomyopathy (ACMP) and ischemic heart disease (IHD) with various NYHA classes. We examined 62 men with ACMP (n = 45) and IHD (n = 17) and NYHA class III-IV CHF. Patients of both groups had lowered ejection fraction (EF), dilated cardiac chambers, and increased left ventricular (LV) myocardial mass index (MMI). Relative LV wall thickness was within normal limits but in the ACMP group it was significantly lower than in IHD group what corresponded to the eccentric type of myocardial hypertrophy. Higher NYHA class was associated with lower EF and larger end diastolic and end systolic LV dimensions. In ACMP it was also associated with larger dimension of the right ventricle while in IHD with substantially larger (by 30%) dimension of atria. Substantial amount of endotoxin found in blood plasma of patients with IHD corresponded to the conception of increased intestinal permeability of in CHF. Alcohol abuse was an aggravating factor of endotoxin transmission and its concentration in patients with ACMP was 3 times higher than in patients with IHD. Patients with ACMP had substantially elevated blood concentrations of interleukins (IL) 6, 8, 12, tumor necrosis factor alpha (TNF-alpha), and its soluble receptor s-TNF-R; they also had twofold elevation of C-reactive protein concentration. ACMP was associated with manifold rise of blood content of brain natriuretic peptide (BNP). Patients with IHD also had elevated blood concentrations of IL 6, 8 and 12 but their values were 1.5-2 times lower than ACMP group. Blood content of TNF-alpha and s-TNF-R in IHD group was within normal limits. Higher NYHA class in ACMP patients was associated with higher concentrations of IL 6 and 8, TNF-alpha, and BNP. In both groups of patients contents of IL-12, s-TNF-R, TGF-1 beta and factors of acute phase of inflammation did not reflect severity of CHF. Functional insufficiency of myocardium in IHD patients was best characterized by blood content of IL-6 while in ACMP patients of BNP.
