Cardiovascular disease and bipolar disorder: A review of pathophysiology and treatment implications.

Abstract

Objective: Despite the well-established increased risk of cardiovascular mortality in individuals with bipolar disorder (BD), prevention and treatment of cardiovascular risk factors and diseases have been largely overlooked in this population. This manuscript reviews the pathophysiological basis of the connection between BD and cardiovascular diseases, highlighting their shared mechanisms, reciprocal interactions, and relevant prevention and treatment strategies.

Methods: For this narrative review, a search was carried out on PubMed using the keywords bipolar disorder, cardiovascular diseases, and cardiovascular risk factors.

Results: The increased frequency of cardiovascular morbidity in BD can be attributed to overlapping biological and psychosocial mechanisms. These mechanisms are complex and involve both direct effects of BD and indirect effects mediated by lifestyle and pharmacological factors. Cardiovascular diseases also significantly exacerbate the clinical course of BD and increase morbidity and healthcare costs; thus, their effective management can improve psychiatric outcomes and vice versa. However, patients with BD frequently encounter healthcare barriers.

Conclusion: Awareness initiatives and research on integrated care are needed to determine the best strategies for improving cardiovascular and psychiatric outcomes in individuals with BD.
