Cardiovascular consequences of anger and other stress states
1Institute for Prevention of Cardiovascular Disease, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston 02215, USA.
Insights
Anger and other emotional stress states can trigger heart attacks and arrhythmias. Research aims to understand and break the link between anger and dangerous cardiac events.
Area of Science:
- Cardiovascular Physiology
- Behavioral Medicine
- Epidemiology
Background:
- Anger is strongly linked to myocardial ischemia and infarction, causing approximately 36,000 heart attacks annually in the US.
- Fear, anxiety, and bereavement also increase cardiac event vulnerability.
- These behavioral stress states activate the sympathetic nervous system, leading to adverse cardiovascular effects.
Purpose of the Study:
- Investigate the pathophysiology of anger and behavioral stress.
- Develop strategies to mitigate the cardiovascular risks associated with anger.
- Understand the link between anger and life-threatening cardiac consequences.
Main Methods:
- Utilizing methodologies from epidemiology, behavioral medicine, and cardiovascular physiology.
- Studying the neurocircuitry and physiological responses to anger.
- Analyzing the impact of stress on cardiac electrical stability and perfusion.
Main Results:
- Activation of central neurocircuitry and the sympathetic nervous system by anger.
- Provocation of acute sinus tachycardia, hypertension, and impaired myocardial perfusion.
- Increased cardiac electrical instability in patients with ischemic heart disease.
Conclusions:
- Behavioral stress states, particularly anger, pose significant risks for cardiovascular events.
- Understanding the physiological mechanisms is crucial for developing interventions.
- Future research aims to sever the link between anger and cardiac events.
Abstract:
Anger is the affective state most commonly associated with myocardial ischaemia and infarction and life-threatening arrhythmias, with at least 36,000 (2.4% of 1.5 million) heart attacks precipitated annually by anger in the United States. Fear, anxiety and bereavement are also implicated in increased vulnerability to cardiac events. The lethal cardiovascular consequences of these behavioural stress states in patients with ischaemic heart disease are attributable to activation of high-gain central neurocircuitry and the sympathetic nervous system, provoking acute sinus tachycardia, hypertension, impaired myocardial perfusion and cardiac electrical instability. The fields of epidemiology, behavioural medicine and cardiovascular physiology have generated new methodologies for studying the pathophysiology of anger and other behavioural stress states with the goal of developing means to sever the link between the anger and its life-threatening consequences.
