Abstract

OBJECTIVE:

To determine the features predictive of atherosclerotic cardiovascular damage in patients with SLE.

METHODS:

SLE LUMINA (LUpus in MInorities: NAture vs nurture) patients (n = 637), aged >or=16 years, disease duration <or=5 years at baseline (T0), of African-American, Hispanic and Caucasian ethnicity were studied. Atherosclerotic cardiovascular damage was defined by the following items of the SLICC Damage Index (SDI) cardiovascular domain: angina or coronary artery by pass surgery, myocardial infarction and/or congestive heart failure; factors associated with its occurrence were examined by univariable and multivariable regression analyses.

RESULTS:

Forty-three (6.8%) of 637 patients developed cardiovascular damage over a mean +/- S.D. total disease duration of 6.6 +/- 3.6 years. Nearly 90% of the patients were women with a mean +/- s.d. age of 36.5 (12.6) years; all ethnic groups were represented. By multivariable analyses, after adjusting for the cardiovascular manifestations present, age [odds ratio (OR) = 1.06; 95% CI 1.03, 1.09], male gender (OR = 3.57; 95% CI 1.35, 9.09) SDI at baseline (OR = 1.28; 95% CI 1.09, 1.50) and CRP levels [highest tertile (OR = 2.63; 95% CI 1.17, 5.91)] were associated with the occurrence of cardiovascular damage, whereas the number of years of education was negatively associated with such outcome (OR = 0.85; 95% CI 0.74, 0.94).

CONCLUSIONS:

Our data suggest that atherosclerotic cardiovascular damage in SLE is multifactorial; traditional (age, gender) and disease-related factors (CRP levels, SDI at baseline) appear to be important contributors to such an occurrence. Tight control of the inflammatory process must be achieved to prevent it.
