Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Rheumatoid arthritis (RA) is a peripheral, symmetric, and inflammatory polyarthritis. Most manifestations of RA are subacute in nature, including gradual onset of morning stiffness, excessive fatigue, and synovitis in various joint areas, most commonly the wrists, metacarpophalangeal, interphalangeal, and shoulder joints, knees, and neck. There are, however, acute and a rapidly worsening manifestations of RA that can be life threatening. Several different extra-articular manifestations can be seen such as pericarditis, myocarditis, interstitial lung disease, or rheumatoid vasculitis.
