Cardiac amyloidosis (CA) results in symptoms of heart failure, atrial and ventricular arrhythmias, conduction disturbances, and profound autonomic dysfunction. These symptoms present unique management challenges as compared with patients without CA, and can be very debilitating. Thus, management of the cardiovascular symptoms of these patients plays a central role in their care. This review presents an overview of the typical cardiovascular manifestations encountered in patients with CA and highlights the key management considerations for each.

Light chain (AL) amyloidosis is a potentially fatal disease of monoclonal plasma cells that leads to accumulation of light chain amyloid fibrils, organ damage, and the manifestations of clinical disease. Meanwhile, coronavirus disease 2019 (COVID-19) is a disease caused by infection with the severe acute respiratory syndrome coronavirus 2 virus, with the potential to cause severe systemic illness and death. ⋯ This overlap creates unique challenges in caring for patients with AL amyloidosis, which are further compounded by the immunosuppressive nature of anti-plasma cell therapies, the need for frequent clinical assessments, and the exclusion of AL amyloidosis patients from initial COVID-19 vaccine trials. Herein, we highlight many of the relevant concerns related to COVID-19 and the treatment of AL amyloidosis, summarize a general approach for AL amyloidosis management amidst the ongoing COVID-19 pandemic, and discuss current guidance about COVID-19 vaccination of patients with AL amyloidosis.

The use of statin therapy in atherosclerotic cardiovascular disease (ASCVD) has demonstrated substantial improvement in morbidity and mortality of the aging population. Despite exhaustive studies demonstrating the benefits of statin therapy linking lower cholesterol levels to decreased vascular events, statin guidelines vary greatly with age, and recommendations are unclear regarding initiation and discontinuation of statin therapy in patients 65 years and older. ⋯ Therefore, patients who meet these criteria, regardless of age, should begin statin therapy. There is also some evidence to suggest that statin therapy may be beneficial in primary prevention of major cardiovascular events, although these data are not as well studied as secondary prevention use of statin therapy, and should therefore be individualized for each patient.

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.

Diagnoses of amyloidosis, particularly transthyretin amyloid cardiomyopathy (ATTR-CM), are steadily increasing throughout the world, but the condition remains underdiagnosed. Patients with amyloidosis may present to a range of medical and surgical specialties, often with multisystemic disease, and a high index of clinical suspicion is required for diagnosis. ⋯ Histological diagnosis of amyloid has been enhanced by laser capture microdissection and tandem mass spectrometry. Early diagnosis and treatment prior to the development of end-organ damage remains essential to improving morbidity and mortality for patients with amyloidosis.
