Anti-inflammatory treatment improves systolic and diastolic tissue doppler parameters in patients with newly diagnosed rheumatoid arthritis.

BACKGROUND: The frequency of cardiovascular system involvement is increased in rheumatoid arthritis (RA) and may result in serious morbidity and mortality. Early intervention and control of the disease activity may reduce the risk of cardiovascular events. The purpose of this study is to examine the effects of steroids and methotrexate (Mtx) on the heart functions of newly diagnosed RA patients.

METHODS: Our study is a prospective cohort study involving thirty-six newly diagnosed RA patients according to the American Society of Rheumatology classification criteria. Right and left ventricular echocardiography, and Doppler parameters were evaluated in these patients thrice; before treatment, after one month of steroid treatment, and after three months of Mtx treatment, and laboratory/clinical parameters were noted.

RESULTS: The mean age of the patients was 52.66 ± 13.66 years. After the treatment, a significant decrease was observed in the values of inflammatory markers (ESR and CRP) and disease activity score (DAS28) [ p  < .05]. Left ventricular tissue Doppler showed an increase in lateral S, septal S, and mitral S waves compared to baseline (8.37 ± 1.89 vs 10.0 ± 1.8 cm/s p  = .001). While there was a decrease in tissue Doppler tricuspid a wave (18.33 ± 4.76 vs 15.63 ± 4.36 p  = .016), an increase in Tricuspid E/e' value and Tricuspid tissue Doppler e/a value was detected after treatment (0.76 ± 0.30) vs 0.94 ± 0.53) p  < .010). Significant changes were found to be more prominent after the Mtx treatment.

CONCLUSION: In RA patients, steroid and Mtx treatment significantly positively affects left ventricular systolic and right ventricular diastolic functions.
