Figure 3 Left ventricular and myocardial diastolic function in rats with POH. A reduced diastolic chamber stiffness is noted for the POH-HF group (A), although there is a trend (p > 0.25) for myocardial stiffness to increase in the same group, as compared with the control and POH-NHF groups (B). LVED(P) or (V) = left ventricular end-diastolic (pressure) or (volume). Abbreviations as in Figure 1.
