Background: Rheumatoid arthritis (RA) is a systemic immune and inflammatory disease associated with excess cardiovascular morbidity and mortality. Pulse wave velocity (PWV) is an index of arterial stiffness and a marker of cardiovascular events.
Objective: To investigate arterial stiffness using carotid-femoral (aortic) PWV measurements in young patients with RA.
Patients and methods: Eight patients (aged 21 to 34 years, seven women, mean RA duration 13.8+/-12.6 months) with RA according to the criteria of the American College of Rheumatology, and eight age- and sex-matched control subjects (aged 22 to 34 years, seven women) were recruited. Aortic PWV was determined using an automatic device, the Complior (Complior Colson, France), which allowed on-line pulse wave recording and automatic calculation of PWV.
Results: The carotid-femoral PWV, systolic blood pressure and heart rate were higher in young patients with RA than in sex- and age-matched control subjects (P=0.03, P=0.02 and P=0.002, respectively). In the young patients with RA, pulse wave propagation time between measurement sites was significantly shorter than in the control group (P=0.02). There were no significant differences in the sex, age, body mass index, waist to hip ratio, diastolic blood pressure, mean blood pressure or pulse pressure between the two groups (P=1.00, P=0.71, P=0.20, P=0.66, P=0.55, P=0.07 and P=0.11, respectively).
Conclusion: The carotid-femoral PWV is increased and pulse wave propagation time is decreased in young patients with RA. Measurements of carotid-femoral PWV may provide a simple and noninvasive technique for identifying patients at increased risk of vascular disease.
