Effect of Candesartan and Verapamil on Exercise Tolerance in Diastolic Dysfunction

Abstract
Diastolic dysfunction may be exacerbated by increased systolic blood pressure (SBP) during exercise. Ang II may contribute to this process. We performed a randomized, double-blind, crossover study of two weeks of candesartan (16 mg) and verapamil (SR 160 mg). The 21 subjects were 64 ± 10 years old with ejection fraction greater than 50%, no ischemia, mitral flow velocity E/A less than 1, normal resting SBP (P
