Cardiovascular rehabilitation has been shown to improve morbidity and mortality in patients with cardiac illnesses; however, the referral rate for eligible patients at Tulane Medical Center has remained below best practice standards. ⋯ This quality-improvement study found that various interventions significantly increased the cardiac rehabilitation referral rate through a straightforward and simple strategy. Further efforts are underway to promote additional referral in order to meet or exceed the >90% best practice standard.

Transthyretin amyloidosis (ATTR) is an under-recognized cause of cardiomyopathy and neuropathy. Until recently, there were limited therapeutic options for ATTR. However, new therapeutics, including tafamidis, patisiran, and inotersen, increase both quality and length of life in patients with ATTR. ⋯ In addition, we discuss emerging ATTR therapies including improvements in drug delivery methods, antibodies to break down deposited amyloid fibrils, and gene editing. ATTR is a prime example of how an understanding of the pathophysiological basis of disease can lead to effective therapies. The future of ATTR therapy is bright, with every reason to believe outcomes will continue to improve.

Update on the Contemporary Treatment of Light Chain Amyloidosis Including Stem Cell Transplantation.
The management of immunoglobulin light chain (AL) amyloidosis is complex. Emerging data have shown promising results for several novel agents. We review the management of AL amyloidosis, including factors that determine transplant eligibility, treatment options for transplant-ineligible patients, and treatment options for relapsed/refractory AL amyloidosis. ⋯ The latter option is based on a landmark trial that led to the first US Food and Drug Administration-approved therapy for AL amyloidosis. For relapsed/refractory disease, novel therapeutics including proteosome inhibitors, immunomodulatory agents, and monoclonal antibodies have shown promising results. In this review, we summarize data for various therapeutics in different clinical scenarios of AL amyloidosis.

Systemic amyloidosis is characterized by extracellular deposition of insoluble fibrillar proteins in multiple tissues, frequently at a distance from the site of synthesis. The 2 most common forms, light chain (AL) and transthyretin (ATTR) amyloidosis can cause peripheral neuropathy and, rarely, myopathy. ⋯ As neurological manifestations of amyloidosis may precede involvement of other organs by several years, recognizing amyloid neuropathy and myopathy are crucial, especially in this new and exciting era of effective therapies for AL and ATTR neuropathy. This review will focus on the neuromuscular manifestations of AL and ATTR amyloidosis, diagnostic approaches, and recent advances in the treatment of amyloid neuropathy.
