B. Chamarthi et al., FEATURES AND PROGNOSIS OF EXERTIONAL SYNCOPE IN LIGHT-CHAIN ASSOCIATED AL CARDIAC AMYLOIDOSIS, The American journal of cardiology, 80(9), 1997, pp. 1242
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 prognos
is in such patients, both in terms of their median survival of 2 month
s and was frequently a precursor of sudden cardiac death.
