[The changes of PRA, ATII, ald, ET and ANP in patients with left ventricular diastolic heart failure and intervention with enalapril].
Fifty patients with left ventricular diastolic heart failure (LVDHF), and 35 patients with left ventricular systolic heart failure (LVSHF) diagnosed by clinical manifestation and radionuclide ventriculography were studied and 20 normal persons served as controls. Plasma renin activity (PRA), angiotensin I (AT I), aldosterone (ALD), endothelin (ET) and atrial natriuretic peptide (ANP) concentrations were measured by radioimmunoassay. Fifty patients with LVDHF were divided into treatment group and control group in a randomized, double blind, control method. Enalpril, CoQ10 and VitE were given in treatment group while only CoQ10 and VitE were given in control group. The therapeutic efficacy was evaluated after 8 weeks of treatment. The results showed that plasma concentration of PRA, AT I, ALD, ET and ANP were increased in LVDHF, but lower than those in LVSHF. After treatment with enalapril plasma PRA was increased while AT I, ALD and ET level were decreased significantly but ANP level had no change in treatment group.
