Variability over time and correlates of cholesterol and blood pressure in systemic lupus erythematosus: A longitudinal cohort study

Abstract

Introduction: Total cholesterol (TC) and blood pressure (BP) are likely to take a dynamic course over time in patients with systemic lupus erythematosus (SLE). This would have important implications in terms of using single-point-in-time measurements of these variables to assess coronary artery disease (CAD) risk. The objective of this study was to describe and quantify variability over time of TC and BP among patients with SLE and to determine their correlates.Methods: Patients in the Toronto lupus cohort who had two or more serial measurements of TC and systolic and diastolic BP (SBP and DBP) were included in the analysis. Variability over time was described in terms of the proportion of p..
