Emerging Insights on the Interplay Between Mental Health and Cardiovascular Disease

Amid rising recognition of psychological factors in cardiology, depression, PTSD and other mental health disorders are now understood to drive a significant share of cardiovascular disease risk beyond traditional metabolic indices.

Mental health disorders contribute to vascular injury through complex mechanisms, with inflammation, dyslipidemia and oxidative stress serving as shared pathways that accelerate atherogenesis and myocardial remodeling, as illustrated by data on systemic inflammation and oxidative stress linked to mental health. These biological disturbances underscore why patients with severe mood disorders such as major depressive disorder and stress disorders like PTSD and acute stress disorder often present with more advanced coronary artery disease at younger ages.

This tension is compounded by further documentation that anxiety and depression correlate with higher rates of hospitalizations for acute coronary events and heart failure, a relationship detailed in research demonstrating how anxiety and depression increase hospitalization risks. Beyond individual symptoms, social determinants such as income, education and environment modulate these interactions.

In the setting of polypharmacy and multiple comorbidities, cannabis use has emerged as a point of uncertainty. However, a recent observational analysis of older adults with established heart disease, limited by sample size and design, suggested no major uptick in arrhythmias, ischemic events or mortality in those using cannabis therapeutically, highlighting the need for larger randomized studies to confirm these findings, as reported in the study on cannabis safety in older heart patients.

Addressing the full spectrum of risk demands a paradigm shift toward integrated mental and cardiovascular care, with coordinated interventions that combine stress management, pharmacotherapy and lifestyle modification. Tailored preventative frameworks aim to reduce incident cardiovascular events through early identification of psychological stressors and mitigation strategies, reflecting recommendations from major cardiovascular societies (e.g., AHA/ACC) on integrated cardiovascular and mental health care.

Key Takeaways

• Mental health disorders such as depression and PTSD drive cardiovascular risk via inflammation, dyslipidemia and oxidative stress.
• Anxiety, depression and social determinants accelerate heart aging and raise hospitalization rates beyond traditional risk profiles.
• Therapeutic cannabis use in older adults with existing heart disease shows no significant increase in major cardiovascular events, but requires individualized evaluation.
• Coordinated care models that integrate psychological and cardiac interventions offer the best approach to mitigate mental health–related cardiovascular risks.
