A Broken Heart Coexisting with Obstructive Coronary Artery Disease

Abstract

Introduction : The intersection of mental health and coronary artery disease (CAD) presents a complex interplay with significant implications for patient outcomes. The emotional burden of living with a chronic condition like CAD can substantially affect a patient's psychological well-being, which in turn may influence recovery and overall quality of life. This literature review examines the critical relationship between psychological distress and the pathophysiology of CAD, underscoring the necessity of an integrated care model.

Methods : This study is a comprehensive literature review synthesizing findings from key articles published between 1995 and 2022. The review analyzes the physiological mechanisms of CAD, such as atherosclerosis and ischemia , the role of psychological factors including stress, depression, and Type D personality , the impact of the COVID-19 pandemic on patient mental health , and the pathophysiology of mental stress-induced myocardial ischemia (MSIMI).

Results : The evidence indicates that psychological factors are potent contributors to CAD progression. Stress and depression can destabilize atherosclerotic plaques, increasing the risk of acute coronary events. The hypothalamic-pituitary-adrenal (HPA) axis is identified as a key mediator in this relationship. Furthermore, the COVID-19 pandemic was found to have significantly exacerbated psychological distress among CAD patients. Research highlights that mental stress can induce myocardial ischemia (MSIMI), particularly in women , and contributes to systemic effects like endothelial dysfunction and arrhythmias.

Discussion : The findings collectively demonstrate that psychological and physiological health in CAD are deeply interconnected. Mental stress is not merely a consequence of the disease but a direct contributor to its pathogenesis and progression. This evidence challenges a purely physiological treatment model, revealing the critical need for a more holistic approach that addresses the emotional and psychological dimensions of the patient's experience to improve outcomes.

Conclusion : A multidisciplinary approach that integrates psychological support into standard CAD treatment protocols is essential. Addressing the mental health of patients with CAD is critical for mitigating disease progression, improving cardiovascular outcomes, enhancing recovery post-surgery, and increasing overall quality of life.
