  • ATM defined as myocardial infarction, angina pectoris with intervention, stroke/transient ischemic attack, and deep-vein thrombosis/pulmonary embolism after onset of RA. ACPA: anticitrullinated protein antibodies; HLA-SE: HLA shared-epitope; DMARD: disease-modifying antirheumatic drug; TNF: tumor necrosis factor.
