Patients with idiopathic inflammatory myopathies, particularly polymyositis, show a high prevalence of atherosclerotic cardiovascular disease.

Polymyositis is a systemic, inflammatory muscle disease, primarily characterized by muscle weakness. It is part of a disease category referred to as myositis, which means inflammation of muscle.
