Pressure overload caused changes in transmitral and tissue Doppler parameters of diastolic function.

Changes in the deceleration rate E/DT (A), the E/A ratio (B), the deceleration time DT (C) and the E/e' ratio (D) in control and pressure overloaded rats at 2, 4 and 6 weeks after aortic banding (AoB). Data are mean ±SEM. Significantly different vs. age-matched control: *, vs. AoB at 2 weeks: §. The numbers in the bars indicate group size.
