Hypertension is associated with preamyloid oligomers in human atrium: a missing link in atrial pathophysiology? Journal of the American Heart Association. 3(6). PMID: 25468655 [PubMed].
Increasing evidence indicates that proteotoxicity plays a pathophysiologic role in experimental and human cardiomyopathy. In organ-specific amyloidoses, soluble protein oligomers are the primary cytotoxic species in the process of protein aggregation. While isolated atrial amyloidosis can develop with aging, the presence of preamyloid oligomers (PAOs) in atrial tissue has not been previously investigated.
