Cardiac Abnormalities in Alzheimer Disease: Clinical Relevance Beyond Pathophysiological Rationale and Instrumental Findings?

This study shows that electrocardiographic and echocardiographic abnormalities, including diastolic dysfunction, are present in patients with AD and that these studies reproduce the pattern of cardiac amyloidosis. These findings suggest that, in AD, there may be subclinical cardiac involvement likely associated with Aβ amyloid deposition. The clinical relevance of these cardiac abnormalities should be evaluated in larger prospective studies.
