Psychological and physiopathological study on coronary patients
Psychotherapy and Psychosomatics
|January 1, 1976
Summary
Psychological symptoms significantly impact nocturnal angina in coronary patients, affecting sleep patterns. However, no direct link was found between these episodes and sleep stages or increased myocardial oxygen consumption.
Area of Science:
- Cardiology
- Psychiatry
- Sleep Medicine
Background:
- Coronary patients often experience angina attacks, which can be influenced by psychological factors.
- A comprehensive approach to psychosomatic patients requires collaboration between cardiology and psychiatry.
Purpose of the Study:
- To define the relationship between psychopathological characteristics and angina attacks in coronary patients.
- To investigate sleep patterns and hemodynamic parameters during nocturnal angina episodes.
Main Methods:
- Polygraphic sleep recordings and psychodiagnostic examination (MMPI) were conducted on 20 patients with nocturnal angina.
- Hemodynamic monitoring was performed in 8 patients during sleep recordings.
- MMPI data were compared with myocardial infarction patients, diurnal angina patients, and healthy controls.
Main Results:
- Sleep patterns were significantly affected, with alterations noted during nights with ischemic episodes.
- No significant correlations were found between ischemic episodes and sleep stages.
- Hemodynamic monitoring did not reveal increased myocardial oxygen consumption during angina attacks.
- Nocturnal angina patients exhibited the most severe symptomatology, suggesting a functional pathogenic mechanism.
Conclusions:
- Nocturnal angina attacks in coronary patients are associated with significant sleep pattern alterations.
- The underlying mechanism of nocturnal angina may be largely functional, despite the absence of direct correlations with sleep stages or hemodynamic changes.
