BACKGROUND AND AIM: To evaluate the prevalence of subclinical cardiovascular (CV) abnormalities in systemic lupus erythematosus (SLE) stratified according to SLE-related organ damage using the Systemic Lupus International Collaborating Clinics (SLICC) damage index.
METHODS AND RESULTS: We selected SLE patients without clinically overt CV events (n=45, 56% with SLICC=0, 44% with SLICC=1-4). CV evaluation was performed using cardiac and vascular echo-Doppler techniques. Post-ischemic flow-mediated dilation (FMD) over nitroglycerine-mediated dilation (NMD) of the brachial artery <0.70 defined endothelial dysfunction. The prevalence of preclinical CV abnormalities (CVAbn, including at least one of the following-carotid atherosclerosis, left ventricular (LV) hypertrophy, low arterial compliance, LV wall motion abnormalities, aortic regurgitation, FMD/NMD<0.70)-was 64% (16/25) in patients with SLICC=0 and 80% (16/20) in those with SLICC>0 (p=not significant (NS)). In particular, the prevalence of carotid atherosclerosis (28% vs. 16%), of LV hypertrophy (12% vs. 6%) and of LV wall motion abnormalities (15% vs. 12%), of low global arterial compliance (18% vs. 10%), prevalence of aortic regurgitation (30% vs. 18%) and/or aortic valve fibrosclerosis (10% vs. 8%), FMD<10% (14+/-5% vs. 14%+/-6) and prevalence of FMD/NMD<0.70 (53% vs. 52%) were comparable in SLE patients with SLICC>0 and in those with SLICC=0 (all p=NS). Of the SLE patients without carotid atherosclerosis, LV hypertrophy, low arterial compliance, LV wall motion abnormalities and aortic regurgitation (n=17), endothelial dysfunction was detected in 50% of those with SLICC=0 (6/12) and in 40% of those with SLICC>0 (2/5, p=NS).
CONCLUSIONS: SLE patients with SLICC=0 often have an elevated CV risk profile due to subclinical manifestations of CV disease detectable by cardiac and vascular echo-Doppler evaluations.
