Serum levels of vitamin E in relation to cardiovascular diseases
Insights
Serum vitamin E levels were lower in individuals with cardiovascular diseases, including acute myocardial infarction and atherosclerosis, compared to healthy controls. This finding suggests a potential link between vitamin E status and heart health.
Area of Science:
- Biochemistry
- Cardiology
- Nutritional Science
Background:
- Cardiovascular diseases (CVD) represent a significant global health burden.
- Vitamin E, a potent antioxidant, plays a role in cellular protection.
- Previous research suggests potential associations between vitamin E and cardiovascular health, but findings remain debated.
Purpose of the Study:
- To investigate serum vitamin E levels in patients with various cardiovascular diseases.
- To compare vitamin E levels between cardiovascular disease patients and a healthy control group.
- To explore potential confounding factors influencing vitamin E levels in CVD.
Main Methods:
- Serum vitamin E levels were quantified in healthy individuals (n=71) and patients with cardiovascular diseases (n=62).
- Cardiovascular disease patient subgroups included acute myocardial infarction (n=31), atherosclerosis (n=23), and myocardial ischemia (n=8).
- Statistical analysis compared mean vitamin E levels between groups, considering confounding variables like age, sex, smoking, BMI, alcohol, diet, and lipids.
Main Results:
- Mean serum vitamin E levels were lower in the cardiovascular disease group (0.98 +/- 0.41 mg%) compared to the control group (1.12 +/- 0.27 mg%).
- Specific CVD subgroups (AMI, AT, MI) showed similar lower vitamin E levels compared to controls.
- The study considered multiple potential confounding factors in the analysis.
Conclusions:
- Overall serum vitamin E levels are reduced in patients with cardiovascular diseases.
- Lower vitamin E status may be associated with the presence of cardiovascular conditions.
- Further research is warranted to elucidate the causal relationship and clinical implications of vitamin E levels in CVD.
Abstract:
Serum vitamin E levels in healthy people (n = 71) and patients with cardiovascular diseases (n = 62) were determined. The cases of cardiovascular disease comprised patients with acute myocardial infarction (AMI) (n = 31), atherosclerosis (AT) (n = 23) and myocardial ischaemia (MI) (n = 8). The mean (+/- SD) serum vitamin E levels of the control group and the group with cardiovascular disease were 1.12 +/- 0.27 mg% and 0.98 +/- 0.41 mg%, respectively. Patients with AMI, AT and MI had corresponding levels of 0.97 +/- 0.48 mg%, 1.00 +/- 0.39 mg% and 1.01 +/- 0.44 mg%, respectively. Overall serum vitamin E levels were lower in the group with cardiovascular disease than in the control group. Patients and the control group are also discussed with respect to a number of potentially confounding parameters such as age, sex, smoking status, quetelet index (kg/m2), alcohol consumption, dietary intake and serum lipids.
