Hypertension may contribute to sudden cardiac death in men. This study found heavier heart weights in male sudden cardiac death victims, suggesting undiagnosed hypertension is likely a factor.
Area of Science:
- Cardiology
- Forensic Pathology
- Hypertension Research
Background:
- Sudden cardiac death (SCD) is a significant cause of mortality.
- The role of hypertension in prehospital SCD remains under investigation.
- Cardiomegaly, or enlarged heart, is a potential indicator of cardiovascular disease.
Purpose of the Study:
- To investigate the association between hypertension and prehospital sudden cardiac death.
- To determine if heart weight differences exist between SCD victims and controls.
- To explore cardiomegaly as a potential marker for undetected hypertension in SCD.
Main Methods:
- Autopsy examinations of 2140 individuals were reviewed.
- Heart weights of 223 subjects were analyzed, excluding known causes of cardiomegaly.
- Heart weights of 40 male SCD victims were compared to age-matched controls dying from noncardiac causes.
Main Results:
- Male victims of prehospital SCD had significantly heavier heart weights compared to controls.
- Control groups included individuals with both severe and minimal coronary atherosclerosis.
- The findings suggest cardiomegaly is prevalent in male SCD victims.
Conclusions:
- Cardiomegaly in male sudden cardiac death victims likely indicates a high prevalence of previously undetected hypertension.
- Hypertension is a probable contributing factor to prehospital sudden cardiac death in men.
- Further research into screening for hypertension in at-risk populations is warranted.
Abstract:
In order to investigate the role of hypertension in prehospital sudden cardiac death, the heart weights of 223 subjects selected from 2140 autopsy examinations were compared. The cases were selected in order to eliminate known distracting causes of cardiomegaly. The heart weights of 40 male victims of prehospital sudden cardiac death were significantly heavier than those of similar aged individuals dying of noncardiac causes. The latter control group included both subjects with severe coronary atherosclerosis and subjects with minimal coronary atherosclerosis. This study suggests that cardiomegaly in male victims of sudden cardiac death probably reflects a high prevalence of undetected hypertension.
