Cardiac amyloidosis: Diagnostic features and clinical implications.

Seven patients with cardiac amyloidosis were referred to King Khaled University Hospital. All patients in this study developed congestive heart failure. They had a long duration of illness and thickened ventricular wall with marked abnormalities in the left ventricular filling, and normal systolic function. Diastolic function is suggested as a possible mechanism of congestive cardiac failure in the patients presented.
