Abstract:

Three patients, 2 women and 1 man, with primary (AL) amyloidosis without congestive heart failure are described; all 3 patients presented reduced I-123 metaiodobenzylguanidine(MIBG) myocardial uptake suggesting marked cardiac sympathetic denervation. This is the first time myocardial adrenergic denervation is described in patients with AL amyloidosis without evidence of congestive heart failure; the observed denervation could be implicated in the pathogenesis of cardiac conduction disturbances which are common in this disease.
