Differences in Immune Cell Mitochondrial Function in Black and White Patients with Heart Failure with Preserved Ejection Fraction

In an unselected cohort of patients with HFpEF, immune cell mitochondria basal respiration and respiratory reserve, as indicated by maximal respiration and spare respiratory capacity, are higher in Black versus White patients. Future studies are warranted to better understand the potential pathophysiological consequences of the observed differences.
