Background: Inflammatory arthritis including rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) are disorders at increased risk of morbidity and mortality for which a validated prognostic tool for facilitating clinical management is needed. CHA 2 DS 2 -VASc (congestive heart failure/hypertension/age diabetes/stroke/vascular disease/age/sex category) score was initially conceived and used to estimate thromboembolic risk in non-valvular atrial fibrillation, and then successfully applied in community populations with sinus rhythm. We tested CHA 2 DS 2 -VASc-score as a prognosticator of adverse outcomes in patients in sinus rhythm with RA/AS/PsA.
Methods: Between March 2014 and March 2015, 414 patients (214 RA, 75 AS, 125PsA) in sinus rhythm without cardiac disease were consecutively analyzed and prospectively followed-up. Primary and co-primary end-points were a composite of allcause death/all-cause hospitalization and CV death/CV hospitalization, respectively.Results: Patients were divided into LOWscore and HIGHscore groups if CHA 2 DS 2 -VASc was = 0/1 point or greater than 1 point, respectively. The HIGHscore group comprised 190 patients who were older with higher prevalence of CV risk factors and arthritis disease activity than 224 LOWscore patients. During a follow up of 36 months, the event rate for primary and co-primary end-point was 37% and 12% in the HIGHscore vs 22% and 4% in LOWscore group (P = .001 and .002 respectively).At multivariate Cox regression analysis CHA 2 DS 2 -VASc-score was related to primary end-point (hazards ratio [HR] 1.30 [1.07-1.59], P = .009) and co-primary end-point (HR 1.35 [1.01-1.79], P = .04) independently of traditional CV risk factors analyzed individually and indexes of inflammation or disease duration. Conclusion: CHA 2 DS 2 -VASc-score accurately identifies in the mid-term patients in sinus rhythm with RA/AS/PsA at different risks for CV and non-CV mortality and hospitalization.
