Abstract
Omega-3 polyunsaturated fatty acids (omega 3-PUFAs) seem to favorably affect cardiac hemodynamics and may benefit the clinical course of heart failure patients. The role of omega 3-PUFAs supplementation on the left and right ventricular function of patients with chronic compensated systolic heart failure, under optimal treatment, was studied. 205 consecutive patients with chronic compensated heart failure, due to ischemic (IHF) or dilated cardiomyopathy (DCM)-NYHA classification I-III, under optimal medical treatment, were enrolled. Participants were 1-to-1 randomized on 1000 mg omega 3-PUFA supplementation or no supplementation, in a non-blinded fashion. Echocardiographic assessment was performed at first visit and 6 months after. Plasma BNP and serum creatinine levels were also measured. As compared with the control group, BNP levels in omega 3-PUFA intervention group were 34.6% lower (p=0.001); end-diastolic and end-systolic left ventricle dimensions were decreased by 2.5% (p=0.047) and 3.7% (p=0.01), maximum diameter of left atrium was decreased by 8.4% (p=0.004), left atrium ejection fraction was ameliorated by 6.03% (p=0.021) and as regards tissue Doppler parameters, TDI_Etv/Atv was decreased in omega 3-PUFA intervention ...Continue Reading
