Multiple Sclerosis and the Cardiovascular System: an overview from cardiovascular risk and clinical characteristics to treatment Esclerose múltipla e

Résumé

Objective: Review the relationship between Multiple Sclerosis (MS) and the cardiovascular (CV) system, as well as the CV manifestations of the disease and the CV complications of treatment. Methods: We performed a non-systematic review of the main databases, with no time limit. Results: People with MS tend to have a different CV risk than the general population, with a higher prevalence of hypertension, hyperlipidemia, overweight, ischemic heart disease, and peripheral and cerebral artery disease. In addition, cardiac alterations can be present in any part of MS patient care. Furthermore, MS treatments are not innocuous for the CV system and require attention, especially considering fingolimod and mitoxantrone. Discussion: The findings could partially explain the higher mortality rates found in this population. Furthermore, at the onset, dysautonomia symptoms, like postural orthostatic tachycardia syndrome, can be used as a clinical marker of patients at higher risk to evolve from clinically isolated syndrome to MS. Finally, MS not only progress badly when associated with CV risk factors but are also at increased risk of CV morbidity and mortality. Conclusion: Physicians addressing MS patients should be aware of their increased cardiovascular risk and the impact that adequate control of these factors can have on disease progression, patient lifespan, and global care.
