both Dilated Cardiomyopathy (DCM) and Hypertrophic Cardiomyopathy (HCM) can present with diastolic dysfunction. Diastolic dysfunction refers to abnormalities in the relaxation or filling of the heart during diastole, the period when the heart is filling with blood. In DCM, the heart muscle becomes weakened and stretched, leading to impaired relaxation and filling of the heart chambers during diastole. In HCM, although the primary issue is thickening of the heart muscle, it can also affect diastolic function, especially in advanced stages or in the presence of other complicating factors. Therefore, both conditions can exhibit diastolic dysfunction, albeit through different underlying mechanisms.
