Charting the perfect storm: emerging biological interfaces between stress and stroke

Area of Science:

• Neuroscience
• Cardiology
• Psychiatry

Background:

• Psychosocial stress is an underestimated risk factor for cardiovascular diseases like myocardial infarction and stroke.
• Stress and psychiatric disorders can be both causes and consequences of cardiovascular disease.
• Biological mechanisms linking stress to cardiovascular morbidity include neuroendocrine dysregulation, oxidative stress, and inflammation.

Purpose of the Study:

• To map the biological interfaces between stress, psychiatric disorders, and stroke.
• To highlight the bidirectional relationship between cardiovascular disease and mental health.
• To review potential mediators and predictors of stress-related vascular morbidity and stroke outcomes.

Main Methods:

• Review of current scientific literature on stress, psychiatric disorders, and cardiovascular disease.
• Analysis of biological pathways implicated in stress-induced endothelial dysfunction.
• Examination of heart rate as a predictor of stroke outcome.

Main Results:

• Stress contributes to endothelial dysfunction through neuroendocrine, inflammatory, and oxidative pathways.
• Heart rate is a valuable, accessible measure reflecting vascular morbidity and psychological distress, and a predictor of stroke outcome.
• FK506-binding protein 51 (FKBP5) and telomere maintenance perturbations are potential mediators between stress and vascular disease.

Conclusions:

• Stress and psychiatric disorders have complex, bidirectional relationships with cardiovascular disease, particularly stroke.
• Interventions targeting biological pathways and heart rate may improve outcomes for stress-related cardiovascular conditions.
• Psychiatric sequelae of cardiovascular events significantly impact recovery, quality of life, and mortality.
