Compared with patients with systemic amyloidosis, patients with isolated amyloid myopathy had a younger age of onset (median, 41.5 vs. 65\u00a0years), no dysphagia (0% vs. 26%) or weight loss (0% vs. 26%), but more frequent calf atrophy (57% vs. 0%), small collections of inflammatory cells on muscle biopsy (43% vs. 0%) and asymptomatic hyper\n                      <jats:styled-content style=\"fixed-case\">CK<\/jats:styled-content>\n                      emia at onset (21% vs. 0%).
