Objective: To compare the effectiveness of stratifying high cardiovascular disease (CVD) risk inpatients diagnosed with rheumatoid arthritis (RA) using the Framingham Risk Score (FRS), modifiedSystematic Coronary Risk Evaluation (mSCORE), 2013 American College of Cardiology/AmericanHeart Association (2013 ACC/AHA) guidelines and QResearch Risk Estimator version 3 (QRISK3),with carotid ultrasound (CUS) serving as the gold standard for detecting subclinical atherosclerosis.Materials and methods: A comparative, observational and cross-sectional diagnostic study was conducted in patients aged 40 to 75 years, of both sexes, with RA and without CVD, at a tertiarycare hospital in Puebla, Mexico. Patients on treatment with one or more disease-modifying antirheumatic drugs (DMARDs) for at least three months were included. Patients with chronic diseases and those who did not undergo a CUS were exc...
