[Pathomorphology of the endocardium and myocardium in the heart injury]
Insights
This study presents a new classification for heart contusion and a diagnostic table to distinguish it from ischemic heart disease, aiding in accurate pathomorphological diagnosis.
Area of Science:
- Cardiovascular Pathology
- Histopathology
- Microscopy Techniques
Context:
- Heart contusion and ischemic heart disease present diagnostic challenges in pathomorphology.
- Distinguishing between myocardial alterations from trauma and ischemia is crucial for accurate diagnosis.
Purpose:
- To develop a morphological classification for heart contusion.
- To create a differential-diagnostic table for myocardial alterations.
- To improve the pathomorphological diagnosis of heart contusion.
Summary:
- Utilized light, polarization, luminescent, and scanning electron microscopy, along with phase contrast and special staining, on human and rat cardiac tissues.
- Examined endocardium and myocardium from patients with heart contusion/ischemic heart disease and rats with experimental heart contusion.
- Proposed a morphological classification and differential-diagnostic table to aid in identifying heart contusion.
Impact:
- Facilitates more accurate pathomorphological diagnosis of heart contusion.
- Provides a structured approach to classifying myocardial damage.
- Enhances understanding of the morphological differences between contusion and ischemic injury.
Abstract:
Light, polarization, luminescent microscopy, phase contrast, special staining methods and scanning electron microscopy were used for studying sections and fragments of the endocardium and myocardium from 123 patients who had died of heart contusion and ischemic heart disease and from 50 rats with experimental heart contusion. The morphological classification of heart contusion and differential-diagnostic table of myocardial alterations due to contusion of the heart and ischemic heart disease are proposed to facilitate pathomorphological diagnosis of heart contusion. The classification of pathomorphological signs in heart contusion is presented.
