Abstract
Background:
Fingolimod may be associated with risk of developing cardiovascular disease (CVD). Studies including reference groups and long follow-up are scarce.
Objectives:
We hypothesized that patients treated with fingolimod would be at higher risk of developing CVD compared to patients treated with natalizumab.
Methods:
A nationwide 12-year cohort study linking individual-level data from the Danish Multiple Sclerosis Registry with health registries on 2095 adult patients with multiple sclerosis (MS) without any health records of CVD at follow-up start. Exposure to fingolimod and natalizumab was defined by the first treatment of at least 3 months. Cohort entry was from 2011 to 2018. We defined CVD as a composite measure, including hypertension, ischemic heart disease, atrial fibrillation, heart failure, and stroke. We used multivariable adjusted Cox regression.
Results:
There were 28.8 and 17.4 CVD events per 1000 person-years in fingolimod and natalizumab groups, respectively. Compared to natalizumab-treated patients, fingolimod-treated patients had a higher risk of CVD (hazard ratio (HR) = 1.57; 95% confidence interval (CI) = 1.18–2.08). Hypertension comprised 200 of 244 CVD events.
Conclusion:
We found an increased risk of CVD in patients with MS treated with fingolimod. This increased risk was mainly due to hypertension.
