Patients with rheumatoid arthritis (RA) have an increased cardiovascular event rate, mainly due to the arterial stiffness which leads to coronary atherosclerosis and concentric left ventricular (LV) geometry. These conditions predispose to LV systolic dysfunction (LVSD), which can be detected by stress-corrected mid-wall shortening (sc-MS), an early prognosticator of cardiovascular events in asymptomatic patients with arterial hypertension and/or diabetes. In these subjects, sc-MS is frequently impaired even though LV ejection fraction (LVEF) is preserved. In this study, we analyzed the prevalence and the factors associated with asymptomatic LVSD measured by sc-MS among patients with RA and verified whether RA per se was independently related to LVSD.
