Abstract
Abstract Aims The PARADIGM-HF study has shown, as is well known, that the association of sacubitril/valsartan (SV) was superior in terms of efficacy compared to enalapril in patients suffering from heart failure chronic cardiac (SC) and reduced systolic function (HFrEF). We have analysed the use of SV in patients with symptomatic HF and HFrEF, andits effect on humoural and functional parameters of easy evaluation. Methods and results From March 2018 to December 2019 we have introduced the SV in 158 patients 135 M and 23 F mean age 40–80 years with fraction of ejection <35% with idiopathic dilated cardiomyopathy (six patients) or post-ischaemic (150 patients), in NYHA III class. Patients were declared eligible according to the ESC 2016 criteria (EF 40%, NT-proBNP> 400 ng/l, target dose of ACE inhibitors/receptor antagonists angiotensin, GFR> 30 ml/min/1.73 m2, serum S-potassium <5.2 mmol/l, treatment with beta-blockers and antialdosteronics). Initially the administration of SV was a cp of 49/51 mg bid up to maximum tolerated dose (one tablet of 97/103 mg bid). All the patients had stopped taking ACE-I or sartans 48 h before and were evaluated at 4-week intervals for two years. In all patients we evaluated: ejection fraction (FE), filtered glomerular, systolic blood pressure, body weight, side effects, hospitalization and mortality. Of the 156 patients, 17 achieved the optimal dose of SV (97/103 mg), 113 achieved SV 49/51 mg bid. In all patients did not experience side effects or alterations of the electrolyte picture and renal function. The SV has determined an improvement NYHA class of at least 1; the echocardiogram showed a significant increase in FE: at follow-up 89 patients reached FE 45%, 44 patients FE 40–44%, and 6 patients about 50%; besides it is an improvement in indexed end-diastolic volume in moles was noted above patients (from 118.4 ± 38.4 to 110.9 ± 30 ml/m2). No case of re-hospitalization. Conclusions Our experience shows that the use of SV is well tolerated, improves functional capacity and ventricular remodelling and that does not modify the parameters of renal function and electrolytic of the patients.
