NCT07741890

Brief Summary

The primary purpose of this study is to evaluate the efficacy of DAPA for the treatment of coronary microvascular dysfunction (CMD) among patients with angina and no obstructive coronary artery disease (ANOCA) and established CMD as compared to placebo.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Change in quantitative myocardial perfusion reserve index (MPRI)

    Change from baseline in the dapagliflozin group compared with the placebo group. A normal MPRI value is usually above 2.0. A value below 1.5 often points to reduced blood flow or poor heart function.

    180 days

Secondary Outcomes (19)

  • Tissue Characterization by Cardiac MRI

    180 days

  • Cardiac Structure and Function by Cardiac MRI

    180 days

  • Cardiac Strain by Cardiac MRI

    180 Days

  • Epicardial Adipose Tissue (EAT) by Cardiac MRI

    180 Days

  • Oxygen-sensitive cardiac magnetic resonance (OS-CMR)-derived BMORE biomarkers

    180 days

  • +14 more secondary outcomes

Study Arms (2)

Dapagliflozin Arm

EXPERIMENTAL

Randomized to dapaflagozin 10 mg once daily for 180 days

Drug: Dapagliflozin (10mg Tab)

Placebo Arm

PLACEBO COMPARATOR

Randomized to placebo once daily for 180 days

Drug: Placebo ( FE)

Interventions

The study will be double blinded by over encapsulation of Dapagliflozin with a matching lactose powder capsule used for the placebo group. All enrolled participants who meet inclusion / exclusion will receive either 10 mg Dapagliflozin (10mg) for 180 days, or placebo, randomized 1:1.

Dapagliflozin Arm

Over encapsulated placebo to match active drug.

Placebo Arm
