Effect of serum fatty acid composition on coronary atherosclerosis in Japan
1Department of Environmental Medicine, Shimane Medical University, Izumo City, Japan.
Insights
Lower levels of high-density-lipoprotein cholesterol and omega-3 fatty acids like eicosapentaenoic acid are linked to coronary artery disease. Eating fish and soy may help prevent heart disease.
Area of Science:
- Cardiovascular Science
- Nutritional Biochemistry
Background:
- Coronary artery disease (CAD) is a leading cause of mortality worldwide.
- Lipid profiles and dietary fatty acids are implicated in the pathogenesis of atherosclerosis.
Purpose of the Study:
- To investigate the association between serum lipid profiles, omega-3 fatty acids, and coronary artery stenosis.
- To explore the impact of dietary habits, specifically fish and soy consumption, on serum fatty acid levels.
Main Methods:
- Serum lipid profiles were analyzed in patients with and without significant coronary stenosis.
- Coronary angiography was used to diagnose coronary stenosis.
- Dietary intake of fish and soy products was assessed and correlated with serum fatty acid levels.
Main Results:
- Patients with significant coronary stenosis had lower levels of high-density-lipoprotein cholesterol and eicosapentaenoic acid compared to controls.
- Higher intake of dark-meat fish correlated positively with serum eicosapentaenoic acid and docosahexaenoic acid (omega-3 fatty acids).
- Soy product consumption was associated with higher serum docosahexaenoic acid.
Conclusions:
- High-density-lipoprotein cholesterol and omega-3 fatty acids may offer protection against coronary atherosclerosis.
- Dietary interventions promoting fish and soy consumption could be a strategy for coronary heart disease prevention.
Abstract:
The serum lipid profiles of patient's with or without significant coronary stenosis diagnosed by coronary angiography and of control subjects were compared. The level of high-density-lipoprotein cholesterol and eicosapentaenoic acid were significantly lower in the patients with significant coronary stenosis than in the control subjects. It suggests that high-density-lipoprotein cholesterol and omega3 fatty acids may have a protective effect on the progress of coronary atherosclerosis. The frequency of eating dark-meat fish was positively associated with serum eicosapentaenoic acid and docosahexaenoic acid, omega3 fatty acids, and inversely associated with serum stearic acid and linoleic acid. The frequency of eating soybean products was positively associated with serum docosahexaenoic acid and inversely associated with serum linoleic acid. It is necessary to discuss a way to popularise a diet of dark-meat fish and soybean products as a means of preventing coronary heart disease.
