Key result
Candesartan significantly improved diastolic heart failure in Dahl salt-sensitive rats, reducing the E/A ratio to 1.98 compared to 4.49 in the vehicle group.

Supports candesartan evaluation in DHF models; hypothesis-generating and should not change clinical practice.
Does candesartan improve diastolic heart failure and cardiac remodeling in Dahl salt-sensitive rats with established DHF?
Absolute Event Rate: 1.98% vs 4.49%
p-value: p=<0.05
In a rat model of diastolic heart failure, candesartan improved diastolic dysfunction, reduced cardiac remodeling, and prolonged survival.
Wake et al. (2005) studied Diastolic heart failure (n=30). Candesartan vs. Vehicle (0.5% carboxymethylcellulose solution) was evaluated on E/A ratio of left ventricular inflow (p=<0.05). Candesartan significantly improved diastolic heart failure in Dahl salt-sensitive rats, reducing the E/A ratio to 1.98 compared to 4.49 in the vehicle group.
