The Impact of Empagliflozin on Left Ventricular Myocardial Stiffness in Heart Failure with Preserved Ejection Fraction

JRCT ID: jRCTs071230020

Registered date:12/06/2023

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: Patients with heart failure with preserved ejecion fraction (HFpEF)
• Date of first enrollment: 15/02/2024
• Target sample size: 38
• Study type: Interventional
• Intervention(s): Empagliflozin (Jadiance10mg)

Outcome(s)

• Primary Outcome: The primary endpoint is the change in left ventricular diastolic characteristics in the left ventricular end-diastolic pressure-volume relationship using a pressure-volume curve catheter (INCA system) at baseline and 6 months after taking 10 mg of empagliflozin.
• Secondary Outcome: Secondary endpoints will include changes in cardiac characteristics such as end-systolic pressure-volume relationship (ESPVR), Ea, single cardiac output work, potential energy, pressure-volume area (PVA), and energy transfer efficiency by the INCA system. In addition, measures of physical functional capacity will be evaluated, including maximal oxygen uptake, oxygen pulse, cardiac output, blood pressure pulse area, arteriovenous oxygen partial pressure gradient, blood pressure, left ventricular end diastolic volume, global longitudinal strain at rest, and left ventricular ejection fraction.
