Leukocyte ascorbic acid and its relationship to coronary artery disease in man
Insights
Patients with coronary artery disease have significantly lower leukocyte ascorbic acid levels. This suggests vitamin C may play a role in atherosclerosis development and progression.
Area of Science:
- Biochemistry
- Cardiovascular Medicine
- Nutritional Science
Background:
- Ascorbic acid (vitamin C) is crucial for connective tissue health.
- Atherosclerosis involves changes in connective tissue, particularly the ground substance.
- Previous research suggests a link between ascorbic acid deficiency and atherosclerotic changes.
Purpose of the Study:
- To compare leukocyte ascorbic acid levels in patients with and without coronary artery disease.
- To investigate the relationship between ascorbic acid levels, atherosclerosis, and smoking.
Main Methods:
- Coronary arteriography was used to diagnose coronary artery disease.
- Leukocyte ascorbic acid levels were measured in patient groups.
- Statistical analysis compared ascorbic acid levels between groups, including smokers and non-smokers.
Main Results:
- Leukocyte ascorbic acid levels were significantly lower in patients with coronary atherosclerosis (P < 0.001).
- Smokers with abnormal coronary arteriograms had significantly different leukocyte ascorbic acid levels compared to non-smokers.
- Observed anatomical changes in atherosclerosis resemble those seen in ascorbic acid deficiency.
Conclusions:
- Ascorbic acid levels are significantly reduced in individuals with coronary atherosclerosis.
- Ascorbic acid may be involved in the pathogenesis and progression of atherosclerosis.
- Further research into the role of ascorbic acid in coronary artery disease is warranted.
Abstract:
The ascorbic acid level of the leukocytes in patients with coronary artery disease was compared to the ascorbic acid level of the leukocytes in patients without coronary artery disease as demonstrated by coronary arteriography. The leukocyte ascorbic acid level was found significantly lower in patients with coronary arteriography. The leukocyte ascorbic acid level was found significantly lower in patients with coronary atherosclerosis (P < 0.001). There was also significant difference in the leukocyte ascorbic acid levels among patients with abnormal coronary arteriograms who smoked compared to those who did not. The anatomical changes secondary to atherosclerotic disease, and mainly those changes related to the ground substance, have been shown to be the changes that have been observed in patients with ascorbic acid deficiency. From the present study, with its limitations, it is suggested that ascorbic acid may play a role in the pathogenesis of atherosclerosis, and although not implicated as an etiological factor in coronary artery disease, it suggests that a closer look at its possible role in the pathogenesis and progression of coronary artery disease is warranted.
