RT Journal Article SR Electronic T1 Primary cardiac amyloidosis in a young man presenting with angina pectoris. JF British Heart Journal JO Heart FD BMJ Publishing Group Ltd and British Cardiovascular Society SP 233 OP 236 DO 10.1136/hrt.52.2.233 VO 52 IS 2 A1 S Saltissi A1 P J Kertes A1 D G Julian YR 1984 UL http://heart.bmj.com/content/52/2/233.abstract AB A 32 year old man presenting with typical angina pectoris was found to have primary cardiac amyloidosis. Myocardial infiltration was strongly suggested by echocardiography, and a histological diagnosis was confirmed by renal biopsy. Nevertheless, technetium pyrophosphate myocardial scanning, recently proposed as a sensitive non-invasive test, showed negative results despite widespread cardiac involvement confirmed at necropsy after unexpected sudden death. Postmortem findings also showed subintimal amyloid material in a severely narrowed right coronary artery. This case highlights several unusual clinical features in a patient with advanced primary cardiac amyloidosis.
