Role of Mental Stressors on Cardiovascular System

Psychosocial stress, including anxiety, depressionDepression, chronic stressStress, and social isolation, is a significant risk factor for cardiovascular diseaseCardiovascular diseases (CVD). The pathophysiological mechanisms involve interactions among the neuroendocrine, immunologic, and vascular systems. Stress activates the hypothalamic–pituitary–adrenal (HPA) axis, releasing cortisol and catecholamines, elevating heart rate, blood pressureBlood pressure, and inflammationInflammation, contributing to endothelial dysfunctionEndothelial dysfunction and atherosclerosisAtherosclerosis. Chronic stress dysregulates the immune system, promoting inflammation and oxidative stressOxidative stress. Inflammatory cytokines like interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) damage endothelial cells and promote plaque formation. Endothelial dysfunction, characterized by impaired vasodilation and increased vascular tone, is central to CVD pathogenesis. Stress-induced sympathetic nervous system and HPA axis activation impair endothelial function. Prolonged stress leadsLead to structural and functional cardiovascular changes, predisposing individuals to hypertensionHypertension, coronary artery diseaseCoronary artery disease, myocardial infarctionMyocardial infarction, and strokeStroke. In addition, is also a risk factor for accelerating biological agingBiological aging. Comprehensive assessment of psychosocial factors in cardiovascular risk management is essential. Collaborative efforts between cardiologists, psychologists, and healthcare professionals are crucial for addressing stress as a modifiable CVD risk factor. Understanding stress-cardiovascular disease interactions requires integrating basic science, clinical research, and public health initiatives. Targeted interventions can mitigate stress-related adverse effects and reduce cardiovascular burden in high-risk populations.
