Relation between ventricular arrhythmias and psychological profile
Insights
Depression may contribute to ventricular arrhythmias in healthy men, but not those with existing heart disease. This finding highlights the importance of mental health in cardiovascular well-being.
Area of Science:
- Cardiology
- Psychology
- Preventive Medicine
Background:
- Ventricular arrhythmias pose significant health risks.
- The interplay between psychological factors and cardiac health requires further investigation.
- Identifying non-cardiac risk factors for arrhythmias is crucial for preventive strategies.
Purpose of the Study:
- To investigate the association between psychological characteristics and ventricular arrhythmias.
- To determine if psychological states influence arrhythmia severity in men with and without ischemic heart disease (IHD).
Main Methods:
- 150 men were studied: 50 with manifest IHD, 50 with IHD risk indicators, and 50 healthy controls.
- 24-hour Holter monitoring was used to record arrhythmias.
- Psychological assessments included the Emotions Profile Index and the Structured Interview for pattern A behavior.
Main Results:
- A depressive emotional state was significantly associated with prognostically severe ventricular arrhythmias in healthy men.
- This association was not observed in men with overt IHD or IHD risk indicators.
- Depressiveness emerged as the second most important factor, after high age, for severe arrhythmias in healthy men.
Conclusions:
- A depressive emotional state may play a role in the development of ventricular arrhythmias in individuals without established cardiovascular disease.
- These findings suggest that psychological interventions could be a valuable adjunct in managing arrhythmia risk in specific populations.
- Further research is warranted to elucidate the mechanisms linking depression and ventricular arrhythmias in the absence of IHD.
Abstract:
The association between psychological characteristics and ventricular arrhythmias was investigated in 150 men (50 with manifest IHD, 50 with risk indicators of IHD and 50 healthy men). Arrhythmias were recorded with 24-hour Holter monitoring. Psychological characteristics were assessed by the Emotions Profile Index and the Structured Interview for pattern A behaviour. A depressive emotional state was associated with prognostically severe ventricular arrhythmia in healthy men, but not in men with overt IHD or risk indicators of IHD. When clinical characteristics and age were taken into account, depressiveness was-among healthy men-the second most important factor after high age. The results suggest that-in absence of IHD or other cardiovascular disease-a depressive emotional state may participate in the formation of ventricular arrhythmia.
