Abstract

Rheumatoid arthritis (RA) is associated with an increased risk of myocardial infarction and congestive heart failure. In RA patients, elevated NT-proBNP levels have been reported to be a prognostic marker of left ventricular dysfunction. In this study, we evaluated cardiorespiratory functional capacity and NT-proBNP levels before and during cardiopulmonary exercise test in early RA (ERA) patients. Twenty ERA patients and 10 healthy controls were studied by color Doppler echocardiography to evaluate ventricular systolic and diastolic function. Arterial stiffness and wave reflections were quantified non-invasively using applanation tonometry of the radial artery. Cardiopulmonary treadmill test was performed to measure peak VO2 and VE/VCO2 parameters. NT-proBNP plasma levels were measured before and at the exercise peak during cardiopulmonary exercise. The peak oxygen uptake [VO2 (ml/min/kg)], the ventilatory equivalents for carbon dioxide (EqCO2), respiratory exchange ratio and arterial stiffness were similar between patients and controls during cardiopulmonary exercise test. Basal and peak cardiopulmonary exercise NT-proBNP plasma levels were comparable in ERA patients with respect to healthy controls. When we analyzed patients according to disease characteristics and cardiovascular risk factors, ERA patients with high disease activity, BMI > 25 kg/m(2) and ACPA positivity presented significantly higher baseline and exercise peak NT-proBNP levels. Cardiorespiratory function is preserved in patients with recent onset of rheumatoid arthritis. The increased basal and exercise peak NT-proBNP plasma levels in patients with negative disease prognostic factors represent a possible marker to stratify the cardiovascular risk in patients with early rheumatoid arthritis.
