Suggests possible racial differences in spironolactone response in HF; hypothesis-generating and should not yet change practice.
Does the potassium response to spironolactone differ between African American and Caucasian patients with heart failure?
African American patients with heart failure exhibit a blunted serum potassium increase in response to spironolactone compared to Caucasian patients, suggesting reduced responsiveness to its renal effects.
Cavallari et al. (2006) studied this question.
