Study summary

Incretin therapy and sodium-glucose- transporter2 inhibitors (SGLT2i) are a treatment for type 2 diabetes (T2DM) affected by heart failure (HF) and treated with cardiac resynchromization therapy (CRT). In this study the investigators will recruit T2DM patients affected by HF with depressed ejection fraction and treated by CRT. These patients will randomly be treated by incretin v/s SGLT2i vs combined therapy with incretin+SGLT2i (and added to conventional hypoglicemic drugs). In these patients investigators will report at follow up CRT-d responders rate, mortality, and hospital admission for HF worsening. Combined therapy with incretin and SGLT2i may reduce hospital admissions for HF in T2DM v/s incretin and/or SGLT2i therapy (added to conventional hypoglicemic drugs).

Study arms

  • Active comparator
    incretin arm

    T2DM with HF treated by CRTd participants will be assigned prospectively to an intervention (incretin therapy plus conventional hypoglycemic drug therapy) according to study protocol to evaluate the effect of the drug on cardiac deaths, all cause deaths, and hospital admission for heart failure.

    Drug: Incretin Effect · Device: Cardiac Resynchronization therapy defibrillator device

  • Placebo comparator
    conventional hypoglycemic drug arm

    T2DM with HF treated by CRTd participants will be assigned prospectively to SGLT2i therapy (plus conventional hypoglycemic drug therapy) according to study protocol to evaluate the effect of the drug on cardiac deaths, all cause deaths, and hospital admission for heart failure.

    Device: Cardiac Resynchronization therapy defibrillator device

  • Active comparator
    Incretin added to SGLT2i

    T2DM with HF treated by CRTd participants will be assigned prospectively to SGLT2i added to incretin therapy (plus conventional hypoglycemic drug therapy) according to study protocol to evaluate the effect of the drug on cardiac deaths, all cause deaths, and hospital admission for heart failure.

    Drug: SGLT-2 inhibitor
