Aim.To assess effects of quinapril on the regulatory-adaptive status (RAS) in patients with chronic heart failure (CHF) NYHA class 1 and arterial hypertension (HT).Material and methods.Patients (n=49) with CHF NYHA class I and HT stage I–II (25 men and 24 women, aged 52.5±8.4 years) were included into an open noncomparative study. A cardio-respiratory synchronization (CRS) test, 6 minute walk test, treadmill test with evaluation of the maximal oxygen uptake during exercise, ambulatory blood pressure monitoring, echocardiography, determination of N-terminal prohormone of brain natriuretic peptide (NT-proBNP) plasma level were performed at baseline and after 6 months of quinapril therapy.Results.The quinapril treatment (average daily dose 17.3±7.9 mg) improved myocardium structural and functional parameters, increased the exercise tolerance, reduced neurohumoral activity, improved the RAS according to CRS test: increase in synchronization range of cardiorespiratory cycles per minute from 8.0±2.1 to 11.0±2.5 (Δ27.3%; p
