Cardiovascular risk estimated in individuals with multiple sclerosis: A case-control study

Abstract

BackgroundPatients with multiple sclerosis (MS) had a 1.5-fold increase in cardiovascular diseases (CVD) mortality, compared with those without MS. Therefore, the aim of this study was to assess the CVD risk in MS patients by multiple cardiometabolic indexes and to investigate associated factors. MethodsThe MS group included 57 patients matched for age and sex to 57 healthy controls. They were evaluated for physical activity, smoking, anthropometric indices, blood pressure, and plasma biomarkers. Framingham risk score (FRS) and multiple cardiovascular risk indexes were calculated. Clinical course of disease, age at onset, disease duration, disease-modifying therapy, relapse rate, EDSS, physical and functional impairment were investigated. ResultsThe mean age was 34.6 years old. The majority (89.5%) in the MS group had a RRMS clinical course and a mild level of disability (EDSS=1.0). WC (p = 0.022) and FM% (p = 0.007) were different between the MS and control groups. The FRS was higher in the MS group (10% versus 0%) and this was related with high prevalence of dyslipidemia (43.8% versus 36.8%). The atherogenic index of plasma (AIP) (0.013) and Castelli risk indexes I (CRI-I) (p = 0.017) and II (CRI-II) (p = 0.008) and non-HDL-C (p = 0.044) were higher in the MS group. ConclusionMS patients, with controlled disease course, have a higher cardiovascular risk than comparable healthy individuals. We emphasize that the use of FRS, and the monitoring of CRI-I and II, as well as AIP, are important lipid markers to manage CVD risk in individuals with MS.
