Study Reveals Potential Causal Link Between Depression and Peripheral Artery Disease

In a recent innovative study, researchers have uncovered compelling evidence suggesting a potential causal relationship between Major Depressive Disorder (MDD) and Peripheral Artery Disease (PAD). Employing advanced genetic analysis techniques, the research sheds light on the intricate interplay between mental health and cardiovascular outcomes, emphasizing the importance of a holistic approach to disease management. The study suggests that effective interventions for cardiovascular diseases, including PAD, may necessitate a combined focus on both physical and mental health.
The study results were published in the Journal of The American Heart Association.
Major depressive disorder (MDD) has been recognized as a contributing risk factor for various cardiovascular diseases. While observational findings have associated MDD with peripheral artery disease (PAD), there is a lack of conclusive causal evidence establishing this relationship. Hence researchers conducted a study to test the association between genetic liability for MDD and genetic liability for PAD. The study utilized Inverse Variance Weighted 2‐Sample Mendelian Randomization, a method that employs genetic information to explore causation rather than relying solely on observational data.
