Heart failure & cardiomyopathies
Dapagliflozin in Black and White Patients With Heart Failure Across the Ejection Fraction Spectrum
Authors' conclusion
The relative benefits of dapagliflozin were consistent in Black and White patients across the range of left ventricular ejection fraction, with greater absolute benefits in Black patients.
