NCT07601867

Brief Summary

This prospective, single-center observational study evaluates the effect of dapagliflozin 10 mg/day on right ventricular-pulmonary artery coupling measured by the TAPSE/PASP ratio in 72 patients with left ventricular ejection fraction \<50% after off-pump coronary artery bypass grafting (OPCAB). The primary outcome is the change in TAPSE/PASP ratio from 1 month after surgery (before dapagliflozin) to 7 months after surgery (after 6 months of dapagliflozin therapy).

Outcome Measures

Primary Outcomes (1)

    The change in the ratio of tricuspid annular plane systolic excursion (TAPSE) to pulmonary artery pressure (PASP) from 1 month after surgery (before dapagliflozin) to 7 months after surgery (after 6 months of dapagliflozin 10 mg/day)

    1 month after surgery (before dapagliflozin) to 7 months after surgery (after 6 months of dapagliflozin 19 mg/day)

Secondary Outcomes (6)

  • Change in Pulmonary Artery Systolic Pressure (PASP)

    1 month after surgery (before dapagliflozin) to 7 months after surgery (after 6 months of dapagliflozin)

  • Change in Pulmonary Vascular Resistance (PVR)

    1 month after surgery (before dapagliflozin) to 7 months after surgery (after 6 months of dapagliflozin)

  • Change in NT-proBNP Levels

    1 month after surgery (before dapagliflozin) to 7 months after surgery (after 6 months of dapagliflozin)

  • Change in Quality of Life (KCCQ-23 Overall Summary Score)

    1 month after surgery (before dapagliflozin) to 7 months after surgery (after 6 months of dapagliflozin)

  • Change in Right Ventricular Fractional Area Change (RV FAC)

    1 month after surgery (before dapagliflozin) to 7 months after surgery (after 6 months of dapagliflozin)

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Adult patients with LVEF below 50% undergoing elective isolated off-pump coronary artery bypass grafting at a single center.

You may qualify if:

  • Age ≥ 18 years
  • Elective isolated off-pump coronary artery bypass grafting (OPCAB)
  • Left ventricular ejection fraction (LVEF) \< 50% documented on pre-operative echocardiography
  • Clinical indication for dapagliflozin according to current guidelines (heart failure with reduced or mildly reduced ejection fraction and/or type 2 diabetes mellitus)
  • Sinus rhythm at the time of each echocardiographic examination
  • Written informed consent

You may not qualify if:

  • Concomitant valve surgery
  • Emergency or urgent CABG
  • Conversion to on-pump during surgery
  • Perioperative myocardial infarction
  • Cardiogenic shock
  • Atrial fibrillation or atrial flutter at any time during the study period
  • More than moderate valvular heart disease
  • Previous CABG or any prior cardiac surgery
  • Severe chronic kidney disease (eGFR \< 25 mL/min/1.73 m²)
  • Contraindication to SGLT2 inhibitors
  • Inability to obtain adequate echocardiographic windows
  • Pregnancy or breastfeeding
