Insights
Coronary heart disease and depression are linked through a complex cardioneural network. Understanding this connection can lead to integrated treatments for better patient outcomes.
Area of Science:
- Cardiology
- Neuroscience
- Psychology
Background:
- Coronary heart disease (CHD) and psychological stress, like depression, are leading causes of morbidity and mortality.
- Managing these conditions in isolation presents significant challenges.
- Recent research highlights the interconnectedness of the heart and brain.
Purpose of the Study:
- To review the cardioneural network linking heart disease and psychological stress.
- To discuss non-invasive methods for assessing this network.
- To explore clinical applications and interventions for integrated management.
Main Methods:
- Literature review of the cardioneural network.
- Discussion of ambulatory and laboratory-based non-invasive measures.
- Exploration of potential clinical and public health applications.
Main Results:
- The cardioneural network involves the heart, brain, spinal cord, and ganglia.
- Non-invasive measures can assess both psychological stress and heart disease severity.
- Integrated management approaches show transformative potential.
Conclusions:
- An integrated approach to managing CHD and depression is supported by the cardioneural network.
- Non-invasive assessments offer valuable insights into cardioneural health.
- Interventions like exercise and biofeedback show promise for cardioneural health.
Abstract:
Coronary heart disease and psychological stress factors such as depression are prevalent and associated with high morbidity/mortality; they are also challenging to manage, especially when treated in isolation of each other. Recent advances support an integrated approach to their management that is built on a foundation of an extensive, multi-component network of neurological structures. In this review, we describe this extensive cardioneural network that encompasses the heart, brain, spinal cord, and ganglia throughout the body, and then discuss ambulatory and laboratory-based non-invasive measures of this network that both measure psychological stress and heart disease severity. Lastly, we discuss their potential transformative clinical and public health applications, and also possible cardioneural interventions such as exercise and biofeedback.
