Features and prognosis of exertional syncope in light-chain associated AL cardiac amyloidosis

Am J Cardiol. 1997 Nov 1;80(9):1242-5. doi: 10.1016/s0002-9149(97)00653-x.

Abstract

Syncope is common in AL amyloid heart disease and in almost 1/3 of our patients who experienced syncope, it was precipitated by physiologic stress. Stress-precipitated syncope was associated with a poor prognosis in such patients, both in terms of their median survival of 2 months and was frequently a precursor of sudden cardiac death.
