title: Systemic inflammation in nonischemic dilated cardiomyopathy.
abstract: We investigated links between inflammatory systemic activation and clinical presentation of nonischemic dilated cardiomyopathy (NIDC). Thirty-one consecutive patients with NIDC (age 57 +/- 10 years, left ventricular ejection fraction 32% +/- 7%) were enrolled in the study: subjects with ischemic heart disease, valvular heart disease, congenital malformations, pulmonary, renal, inflammatory, or metabolic diseases were excluded. All patients underwent physical examination, electrocardiography, chest radiology, echocardiography, and coronary angiography. Plasma levels of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and fibrinogen were ascertained. New York Heart Association (NYHA) functional class was significantly correlated with concentrations of fibrinogen (r = 0.42, P < 0.05) and CRP (r = 0.52, P < 0.01), and with ESR (r = 0.46, P < 0.05). Left ventricular ejection fraction was inversely related to fibrinogen (r = -0.41, P < 0.05) and ln CRP (r = -0.46, P < 0.05). Correlations between NYHA class and markers of inflammation remained significant also after correction for age, sex, and cardiovascular risk factors. Ongoing treatment with statins was associated with reduced CRP levels. Inflammatory markers are increased in patients with NIDC proportionally with severity of symptoms and systolic impairment. Systemic inflammation might be related to deterioration of NYHA class.
