Comparison of effectiveness of therapy with lisinopril and fosinopril in patients with diastolic chronic heart failure in the presence of hypertension disease

Abstract

Aim. Сompare the effectiveness of combination therapy with lisinopril and fosinopril in patients with diastolic chronic heart failure (CHF) in the presence of hypertension disease (HD), considering its impact on the regulatory adaptive status (RAS). Materials and methods. The study take parted 69 patients with CHF II functional class according to the classification of the New York Heart Association in the presence of HD III stage with preserved systolic function of the left ventricle (left ventricular ejection fraction ≥50%), who were randomized into two groups for treatment with lisinopril (13.7±3.7 mg/day, n=34) or fosinopril (14.5±4.1 mg/day, n=35). As part of combination pharmacotherapy, patients were included nebivolol (7.2±2.4 mg/day and 7.0±2.2 mg/day), and acetylsalicylic acid when required (100 mg/day, n=8 and 100 mg/day, n=7), atorvastatin (15.7±4.9 mg/day, n=14 and 16.9±4.6 mg/day, n=16) respectively. Initially and after six months, the following was done: a quantitative evaluation of the RAS (by cardio-respiratory synchronism test), echocardiography, holter monitoring of blood electrocardiograms, all-day monitoring of pressure, treadmill test, determination of the N-terminal precursor of the natriuretic brain peptide level in blood plasma, six-minute walking test, subjective evaluation of quality of life. Results. Both combined pharmacotherapy schemes comparably improved structural and functional state of the heart, neurohumoral activation and optimized blood pressure. However, in this case, the use of fosinopril, in comparison with lisinopril, positively affected on RAS, increased exercise tolerance and improved quality of life more. Conclusion. In patients with diastolic CHF in the presence of HD III stage as part of the combination therapy, the use of fosinopril, in comparison with lisinopril, may be preferable because of a more pronounced positive effect on RAS.
