Resumo
Background: Rheumatoid arthritis (RA) can cause extra-articular manifestations, and the myocardium can be a target. This study aimed to describe structural and functional cardiac echocardiographic variables in RA patients and to evaluate whether vitamin D (VD) levels and inflammation markers, evaluated by Disease Activity Score-28 for Rheumatoid Arthritis with C-reactive protein (DAS28-CRP), are associated with cardiac remodeling (CR) in this population. Material/Methods: This prospective observational study evaluated 90 patients with RA in Botucatu University Hospital wards from 2014 to 2017. Clinical data were recorded, including demographic information, comorbidities, length of disease, and treatment type. Serum VD and C-reactive protein levels were measured, and the DAS28-CRP was calculated. A transthoracic echocardiography study was performed. The outcome evaluated was CR. This parameter was assessed by left ventricular geometric patterns and left atrium diameter. Results: We evaluated 90 RA patients. The mean age was 52.9±10.8 years, and 17.8% were male. The length of the disease was 96 (60-180) months. Serum VD levels were 30.7±10.4 ng/mL and the DAS28 was 2.7±0.9. Regarding the CR parameters, 56.7% had altered left ventricular geometric patterns and 25.8% had enlargement of left atrium diameter. Even in multivariate analysis, the left ventricular geometric patterns were not associated with the VD levels and the inflammation marker used. However, sufficient VD levels protect from left atrium enlargement (OR: 0.905; IC 95%: 0.843-0.973; P=0.007). Conclusions: Low serum vitamin D values, but not inflammation, are associated with CR in patients with RA.
