Differential renal effects during orthostasis in healthy volunteers leave open potential candesartan advantages in heart failure; hypothesis-generating.
Does metoprolol or candesartan improve renal haemodynamics and sodium handling during orthostatic stress in healthy individuals?
In healthy individuals undergoing orthostatic stress, both metoprolol and candesartan prevented sodium retention, but only candesartan improved renal blood flow and promoted sodium excretion during recovery, suggesting potential mechanisms for their benefits in heart failure.
