Abstract:
PURPOSE:To identify the principal forms of cardiac amiloydosis presentation in a terciary hospital. METHODS:Eight cases with cardiac amyloidosis were identified. Five were women, their ages ranged from 23 to 83 years (mean 62). After a medical history and clinical examination the patients were submitted to complementary tests: electrocardiogram (EKG), echocardiogram (ECHO), scintigraphy with technecium pirophosphate and cardiac biopsy these results allowed the identification of their clinical situation. RESULTS:Seven patients referred dyspnea, 6 were in heart failure, 1 patient had syncope. The EKG identified complete atrioventricular (AV) block in 4 patients, and antero septal inactive area in the other 4. The ECHO showed normal cardiac diameter in all (mean left ventricular diastolic diameter of 46.8) and slight reduction of left ventricular ejection fraction; hypertrophy of the left ventricular septal and posterior walls in all cases, in 7 cases there was a hyper refractile granular sparkling ECHO. Two different groups were identified: one with complete AV block and the second with restrictive cardiomyopathy. The prognosis was different in these two groups. Those with complete AV block evolved better after pacemaker implantation and those with restrictive cardiomyopathy had refractory heart failure and 3 of them died. CONCLUSION:The increased free wall and septal thickness, the slight systolic dysfunction and the infiltration aspect at ECHO allow us to identify the great majority of the cases. Those patients with restrictive cardiomyopathy evolve with refractory heart failure and most of them die in a few months.
