Abstract

IntroductionHeart failure (HF) with reduced ejection fraction (HFrEF) remains a challenging problem due to its high mortality rate. The PARADIGM HF trial and a new class of drugs – angiotensin receptor–neprilysin inhibitors (ARNIs) – managed to change the current perception of HF treatment by reducing cardiovascular mortality and morbidity as well as HF hospitalizations compared with enalapril and have emerged as an evidence-based therapy for HFrEF. Another novelty in HF therapy is dapagliflozin, a sodium-glucose transporter-2 inhibitor (SGLT2i) which decreased the rates of cardiac death and worsening of HF in the DAPA-HF trial, when added in other guideline recommended therapy. A recent study evaluated the potency of dapagliflozin in terms of mortality and deterioration of HF, in patients taking sacubitril/valsartan and in patients who were naive.Material and methodsA prospective cohort study of 30 symptomatic HF patients with EF < 35% (aged 65 ±10 years) was conducted. Diabetic (2TDM) patients of NYHA status II–III, previously treated with ARNI, -blocker, and mineralocorticoid receptor antagonists (MRA) were included. Dapagliflozin was added to their therapy.ResultsEchocardiographic evaluation revealed improvement of both conventional tissue Doppler and diastolic strain parameters by dapagliflozin addition on HF therapy.ConclusionsDapagliflozin impact on diastolic function may explain the symptom amelioration and the improvement of quality of life. And more specifically, the ratio of early diastolic transmitral flow velocity to global strain rate at the early filling phase of diastole (E/SRE)may be considered a reliable index of HF therapy responders.
