Key result
Hypertrophic cardiomyopathy was associated with higher left ventricular diastolic stiffness than controls (0.199 vs 0.091 mmHg/ml, p<0.01), while pulmonary venous stiffness remained similar.

Preserved pulmonary venous compliance in HCM may buffer congestion risk; leaves open mechanisms and clinical relevance.
Observational (n=26)
Absolute Event Rate: 0.199% vs 0.091%
p-value: p=<0.01
The pulmonary venous system remains compliant despite decreased LV compliance in HCM, maintaining a reservoir function that helps prevent pulmonary edema.
Goto et al. (1986) conducted an observational in Mitral stenosis, angina pectoris, hypertrophic cardiomyopathy (n=26). Hypertrophic cardiomyopathy vs. Control group was evaluated on Stiffness of the left ventricle in diastole (mmHg/ml) (p=<0.01). Hypertrophic cardiomyopathy was associated with higher left ventricular diastolic stiffness than controls (0.199 vs 0.091 mmHg/ml, p<0.01), while pulmonary venous stiffness remained similar.
