Transthyretin amyloidosis, either mutant or wild-type, has a more favorable survival rate compared with that of AL or other types of amyloidosis. The natural history of ATTRwt CM is better than other forms of amyloid CM. Death in most patients is due to cardiac causes, including sudden ...

Cardiac amyloidosis is a form of restrictive cardiomyopathy resulting in heart failure and potential risk on arrhythmia, due to amyloid infiltration of the
Ruberg, MD2 Since the identification of a valine-to-isoleucine substitution at posi- tion 122 (TTR V122I; pV142I) in the transthyretin (TTR)-derived fibrils extracted from the heart of a patient with late-onset cardiac amyloidosis, it has become clear that the amyloidogenic mutation ...
(n = 260) with advanced AL-CA (Mayo stage IV) treated with birtamimab plus standard therapy compared to control group (survival rate of 74% vs. 49%, at 9 months) [94]. Based on these results, the phase 3 AFFIRM-AL trial is enrolling patients with AL amyloidosis at Mayo stage...

Scans were evaluated both visually and using quantitative analysis by observing the heart-to-skull ratio of imaging agent retention. Heart-to-skull retention was linked to levels of cardiac amyloidosis. Patients with a lower heart-to-skull score experienced a better rate of survival, free of major...
Both AL and ATTR amyloidosis are progressive diseases with median survival from diagnosis of less than 6 months and 3 to 5 years, respectively, if untreated. In this regard, death occurs in most patients due to cardiac causes, mainly congestive heart failure, which can be prevented due to ...
Amyloidosis is caused by extracellular deposition of abnormal protein fibrils, resulting in destruction of tissue architecture and impairment of organ function. The most common forms of systemic amyloidosis are light-chain and transthyretin-related (ATTR). ATTR can result from an autosomal dominant heredi...
Cardiac amyloidosis (CA) is caused by the deposition of abnormal amyloid fibrils in the myocardium, including the ventricular walls, valves, and conduction system. This infiltrative process typically causes heart failure with preserved ejection fraction (HFpEF) and, in more advanced stages, degenerates...
