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.

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 combination of peripheral arterial disease and atrial fibrillation is linked with high risk of mortality and stroke. This study aims to investigate the impact of atrial fibrillation on patients with diagnosed peripheral arterial disease. ⋯ In peripheral arterial disease patients, atrial fibrillation is a risk factor for mortality, stroke, and heart failure. This emphasizes the need for proactive surveillance and holistic management of these patients.

More than 35 amyloid precursor proteins have been identified and many have tropism for the kidney. Renal amyloidosis is most commonly seen in AL and AA amyloidosis and the main clinical manifestations are proteinuria and progressive renal dysfunction. ⋯ Management of renal amyloidosis typically combines therapy targeting the underlying amyloid process and supportive management. Patients with renal amyloidosis who progress to end-stage renal disease can be treated with dialysis, and in selected patients, with renal transplantation.
