Effect of Dapagliflozin on Right Ventricular-Pulmonary Artery Coupling After Off-Pump Coronary Atery Bypass Grafting (DAPA-RV-CABG)
Effect of Dapagliflozin on Right Ventricular-Pulmonary Artery Coupling After Off-Pump Coronary Artery Bypass Grafting: a Prospective Single-Center Study
Descripción general del estudio

Descripción detallada
Patients undergo echocardiography at three time points: pre-operatively (T0), at 1 month post-surgery before dapagliflozin initiation (T1), and at 7 months post-surgery after 6 months of dapagliflozin 10 mg/day (T2).
The primary objective is to evaluate the change in the TAPSE/PASP ratio from T1 to T2.
Secondary objectives are to evaluate changes from T1 to T2 in:
- Pulmonary artery systolic pressure (PASP)
- Pulmonary vascular resistance (PVR)
- Right ventricular fractional area change (RV FAC)
- Left ventricular ejection fraction (LVEF)
- NT-proBNP levels
- Kansas City Cardiomyopathy Questionnaire-23 (KCCQ-23) overall summary score
The study aims to provide mechanistic insight into the effects of SGLT2 inhibition on right ventricular-pulmonary artery coupling after off-pump coronary artery bypass grafting.
