Background:
Vascular diseases (VDs) are increasingly studied in multiple sclerosis (MS) due to their significant impact on disability and mortality. Our aim was to evaluate VD incidence rates and determine the prevalence of VD-related mortality.
Material And Methods:
Our study followed the PRISMA 2020 guidelines. We searched PubMed, Google Scholar, Europe PMC, and Web of Science from the inception up to April 30th, 2024. Data analysis was performed using the R statistics package program. Sensitivity analysis, subgroup analysis, and meta-regression were conducted for significant heterogeneity.
Results:
We collected 23 studies. Patients with MS exhibited significantly higher rates of VD compared with controls. Patients with MS showed a significantly higher rate of heart failure (HF), venous thromboembolism (VTE), peripheral vascular disease (PVD), and stroke, although the incidence rate of atrial fibrillation/flutter was significantly lower compared with controls. High blood pressure tended to be lower compared with controls. The highest rate of VD was within the first 10years of follow-up, significantly for myocardial infraction, VTE, and stroke, compared with controls. Regarding mortality, the prevalence of VD-related mortality among deceased individuals with MS was 16.7% [95% CI 11.8;22.0].
Conclusion:
Our meta-analysis revealed a significant dynamic nexus between MS and VD. MS may act as an independent risk factor for certain VDs, yet it could also be a protective factor against others. Physicians should consider VD and mortality related to VD when managing patients with MS.
