Plain English summary of protocol

Background and study aims
Heart failure with reduced ejection fraction (HFrEF) happens when the heart muscle cannot pump forcefully enough to move the blood around the body. The effects on the heart muscle of the sodium-glucose co-transporter-2 inhibitor dapagliflozin, which is used to treat type 2 diabetes and heart failure, are not clear. Therefore, the aim of this study is to determine the effect of the addition of dapagliflozin to conventional treatment in patients with HFrEF.

Who can participate?
Patients aged 18 or over with mild to severe HFrEF.

What does the study involve?
Non-invasive imaging was used to compare the function of the heart muscle in patients with HFrEF given dapagliflozin in addition to their conventional treatment for HF for 6 months with a control group of patients with HFrEF receiving only their conventional HF treatment for the same time period.

What are the possible benefits and risks of participating?
Benefits and risks not provided at time of registration

Omar Yacef Hospital (Algeria)

Scientific titleImpact of dapagliflozin on echocardiographic parameters in patients with heart failure and reduced ejection fraction
Study objectivesDapagliflozin has proven its effectiveness in reducing morbi-mortality in patients with heart failure. However, its effects on systolic and diastolic echocardiographic function are less known. The objective of this study is to describe the impact of the addition of dapagliflozin to conventional treatment on echocardiographic parameters in patients with HFrEF <40% compared to a control group of patients after 6 months of treatment.
Ethics approval(s)This is an observational, case-control study, which does not require ethics approval under Algerian law because the treatment is already approved in this pathology and ultrasound remains a non-invasive and mandatory examination in the usual follow-up of these patients.
Health condition(s) or problem(s) studiedHeart failure and reduced ejection fraction
InterventionA group of patients with HFrEF<40% in stage II to IV of NYHA receiving classic HF treatment with dapagliflozin 10 mg/day were compared with a group of patients with the same profile receiving classic HF treatment only for 6 months using echocardiography at a follow-up of 7 months for ejection fraction (EF), left ventricular dysfunction (LVd), systolic pulmonary pressure (sPAP) and longitudinal strain
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Applicable
Drug / device / biological / vaccine name(s)Dapagliflozin
Primary outcome measure1. Heart failure functional classification assessed using NYHA stage at the first visit
2. Hospitalization rate recorded in our HF hospital registry at the end of the study
3. Ejection fraction (EF) measured by an echocardiogram (ECG) at the first visit, 3 months, and at 7 months (5-8 months) follow-up
Secondary outcome measures1. Mean left ventricular dysfunction (LVd) measured by an echocardiogram (ECG) at the first visit, 3 months, and at 7 months (5-8 months) follow-up
2. Systolic pulmonary pressure (sPAP) measured by an ECG at the first visit, 3 months, and at 7 months (5-8 months) follow-up
3. Mean longitudinal Strain measured by ECG at the first visit, 3 months, and at 7 months (5-8 months) follow-up
4. Urinary tract infection assessed by interrogation (presence of burning urination) and urine strip (Labstix) at each consultation (at the first visit, 3 months, and at 7 months (5-8 months) follow-up) and if necessary cytobacteriological urine examination (in the case of burning urination)
