A Narrative Review on Mental Stress and Cardiovascular Disease: Evidence, Mechanisms, and Potential Interventions

Abstract

Cardiovascular disease (CVD) is the leading cause of death in the United States and worldwide. Psychosocial stress is an important risk factor implicated in a higher incidence of CVD. There are two prevalent categories of stress – acute psychosocial stress (APS) and chronic psychosocial stress (CPS). APS is typically caused by acute dramatic events such as natural disasters, sexual abuse, terroristic attacks, and sudden death of a loved one, while CPS is usually related to environmental, relationship, and work stressors. Both categories of psychosocial stress are associated with substantial CVD morbidity and mortality that carries a magnitude of risk equal to that of conventional CVD risk factors. As a result, more research is needed to understand the detrimental impacts of psychosocial stress on cardiovascular health and related mechanistic underpinnings that, in turn, would further facilitate the development of novel therapeutic targets. This review aims to elucidate the potential pathophysiological mechanisms by which psychosocial stress can influence CVD. In addition, we aim to discuss the current targeted therapeutic interventions (pharmacological and nonpharmacological) and possible future research directions.

Effects of Stress and Anxiety on Pregnant Women's Cardiovascular Health: A Narrative Review

“…The mechanisms that link mental stress to CVD are illustrated by Ahmad and his team [77]. The interaction mechanisms by which mental stress on the brain-immune-arterial axis raises the risk of cardiovascular events are described in their research.…”

“…The interaction mechanisms by which mental stress on the brain-immune-arterial axis raises the risk of cardiovascular events are described in their research. Chronic or acute mental stress triggers the amygdala/prefrontal stress-related neural network response, which affects the vasculature and activates the autonomic nervous system, hypothalamic-pituitary-adrenal axis, and bone marrow [77].…”

Unveiling the sleep‐cardiovascular connection: Novel perspectives and interventions—A narrative review

“…8 Another study on three preindustrial societies illustrated that, on average, hunters and gatherers in Africa and Bolivia have a sleep duration of 5.4-7.1 h. 9 A growing percentage of people are limiting their sleep due to rising demands and lifestyle modifications such as extended work hours, increased environmental lighting, and the inclusion of new communication devices that create a lifestyle of perpetual availability. 10,11 However, these shifts in sleep patterns aren't without repercussions. Straying from the recommended sleep duration could significantly endanger health, as the extent of the adverse effects of irregular sleep on physical and mental well-being are only just starting to be uncovered.…”
