Insights
Coronary atherosclerosis is prevalent in young trauma victims, with significant narrowing in 20.7%. Aggressive risk factor modification is crucial for this demographic to prevent severe coronary artery disease.
Area of Science:
- Cardiovascular pathology
- Atherosclerosis research
- Trauma pathology
Background:
- Coronary artery disease prevalence in young men has been historically tracked through military conflict autopsies.
- Korean War data showed 77.3% coronary artery involvement; Vietnam War data indicated a decline to 45% with 5% severe disease.
Purpose of the Study:
- To determine the prevalence, severity, and location of coronary atherosclerosis in individuals under 35 years old who died from noncardiac trauma.
- To assess the extent of coronary artery narrowing in young trauma fatalities.
Main Methods:
- Pathologic examination of coronary arteries in 111 noncardiac trauma victims (mean age 26 years).
- Gross and microscopic analysis, including computerized planimetry, to quantify atherosclerotic plaque and lumen compromise.
- Coronary artery segments were sectioned, stained, and digitized for precise measurement.
Main Results:
- Coronary atherosclerosis was present in 78.3% of the study group.
- Significant narrowing (>50% lumen compromise) occurred in 20.7%, and severe narrowing (>75%) in 9%.
- No demographic or anatomic factors differentiated levels of atherosclerosis; proximal involvement was common, except distally in the right coronary artery.
Conclusions:
- The prevalence of coronary atherosclerosis in young trauma victims is similar to Korean War casualty data.
- A significant proportion (20%) exhibited left main or multi-vessel involvement, highlighting the need for early intervention.
- Aggressive modification of cardiovascular risk factors is essential in young individuals to mitigate severe coronary artery disease progression.
Objectives:
The aim of this study was to look at the prevalence of coronary atherosclerosis, its severity and site of involvement in patients < 35 years old who died from noncardiac trauma.
Background:
Autopsies performed on casualties of the Korean War revealed coronary artery involvement in 77.3% of the hearts studied, and data after the Vietnam War noted the presence of atherosclerosis in 45% of casualties with severe disease in 5%, suggesting a decline in the prevalence of coronary atherosclerosis in young men.
Methods:
One hundred eleven victims of noncardiac trauma (86.4% white with a mean age of 26 +/- 6 years) underwent pathologic examination of their coronary arteries to estimate the presence and severity of coronary atherosclerosis grossly, microscopically and through computerized planimetry. Identified segments of the coronary arteries were sectioned at 3-mm intervals, stained with special stains and after microscopic examination transferred to videotape and digitized to allow estimation of the percent compromise in the lumen area by atherosclerotic plaque.
Results:
Signs of coronary atherosclerosis were seen in 78.3% of the total study group, with > 50% narrowing in 20.7% and > 75% narrowing in 9%. No demographic or anatomic features separated the groups with less or more severe involvement of their coronary arteries. Proximal involvement was more common except in the right coronary artery, which was as frequently involved distally.
Conclusions:
The overall prevalence of coronary atherosclerosis in a young, predominantly male study group was comparable with that noted after the Korean War. Left main or significant two- and three-vessel involvement was noted in 20% of the group studied and emphasizes the need for aggressive risk factor modification in this group.
