[Pathological analysis of sudden coronary death in 31 autoptic cases]
Insights
Sudden coronary death, often unexpected, is linked to severe coronary artery stenosis and myocardial infarction. These conditions are key factors in fatal cardiac events, even without prior symptoms.
Area of Science:
- Cardiology
- Pathology
Context:
- Sudden coronary death (SCD) represents a significant portion of cardiovascular mortality.
- Understanding the pathological basis of SCD is crucial for prevention and treatment strategies.
Purpose:
- To investigate the pathological findings in cases of sudden coronary death.
- To identify the correlation between coronary artery disease severity and SCD.
Summary:
- A study of 31 sudden coronary death cases (19.4% of 160 coronary heart disease autopsies) revealed significant atherosclerotic stenosis (grade 4) in 25 cases, with 18 involving multiple coronary artery branches.
- Myocardial infarction was present in 24 cases, often old (14 cases) and combined with acute infarction (8 cases).
- Ventricular aneurysm was noted in 8 cases, and cardiac rupture in one, highlighting diverse pathological outcomes.
Impact:
- Severe coronary stenosis and myocardial infarction are identified as primary contributors to sudden coronary death.
- Findings underscore the importance of aggressive management of coronary artery disease to reduce SCD incidence.
Abstract:
31 cases of sudden coronary death (within 1 hour, unexpected death) in 160 autoptic cases of coronary heart disease were studied (19.4%), including 24 male and 7 female; age 16-79, average 59.5. Most cases of sudden death had no obvious inductive causes. 18 patients died without cardiac symptoms, including those died before admission or during deep sleep. There was atherosclerotic stenosis (grade 4), of the coronary artery in 25 cases, of which 18 cases were with multiple branches involvement (grade 4) and 7 cases were with simple branch damage. Myocardial infarction was found in 24 cases, and myocardial ischemia in 7 cases. Old myocardial infarction was seen in 14 cases, and it was combined with acute myocardial infarction in 8 cases. Simple acute myocardial infarction was only seen in 2 cases. 8 cases showed ventricular aneurysm and 1 patient died of cardiac rupture. Conclusively, severe coronary stenosis and myocardial infarction are considered as one of the important bases of sudden coronary death.
