Histological assessment of myocardium in lethal ethanol intoxication
Insights
Sudden cardiac death in healthy individuals may be linked to ethanol intoxication. This study found alcohol damages heart muscle cells (cardiomyocytes), causing enlargement and fragmentation, indicating a harmful effect on the myocardium.
Area of Science:
- Cardiovascular Pathology
- Toxicology
- Histology
Background:
- The exact cause of sudden death in healthy individuals with incidental ethanol intoxication is unclear.
- Cardiogenic factors are suspected as underlying mechanisms.
Purpose of the Study:
- To conduct a histological assessment of the myocardium in cases of lethal ethanol intoxication.
- To analyze myocardial tissue from deceased males aged 29-45 years.
Main Methods:
- Myocardial tissue samples were collected from the left ventricle and interventricular septum.
- Standard histological procedures and morphometric analysis were performed.
- Cardiomyocyte number, area, circumference, and circular deviation were assessed.
Main Results:
- Significant increase in cardiomyocyte area and circumference observed.
- Cardiomyocyte fragmentation and segmentation noted, with enlarged cell nuclei.
- Presence of lymphocytic infiltration in some myocardial samples.
Conclusions:
- Alcohol consumption exerts a detrimental effect on the myocardium.
- Histological changes suggest alcohol-induced cardiac damage.
- Further research is warranted to fully elucidate ethanol's impact on cardiac function and sudden death.
Background:
The pathological mechanism of sudden death in healthy persons following incidental ethanol intoxication has not yet been fully elucidated and might be underlain by cardiogenic causes.
Aim:
Histological assessment of the myocardium in lethal ethanol intoxication. The analysis was based on a histological assessment of specimens of the myocardium obtained from the hearts of 30 deceased males within the age range 29-45 years.
Methods:
The material for the study was taken from the myocardium of the anterior wall of the left ventricle and interventricular septum of the heart. The fixation material was first examined according to the standard histological procedure and subsequently subjected to a morphometric examination, which assessed the number of cardiomyocytes, their area, circumference, and circular deviation.
Results:
The examination showed an increase in the area and circumference of cardiomyocytes, as well as fragmentation and segmentation of cardiomyocytes with a significant enlargement of cell nuclei. Additionally, it revealed the presence of lymphocytic cells in several cases.Conclusions: The obtained findings indicate a harmful influence of alcohol on the myocardium.
