Platelet fatty acids in coronary heart disease, dyslipidemia, hypertension and healthy controls.Southeast Asian J Trop Med Public Health. 2003 Sep; 34(3):675-81.SA
A cross-sectional study was performed to investigate 250 volunteers from Pramongkutklao Hospital, Samphanthawong district, Wat Chaiyapreukmala and Wat Pradoo in Taling Chan district. They were divided into groups of 35 apparently healthy males, 16 males with coronary heart disease, 37 males with dyslipidemia and 9 males with hypertension with age ranges of 24-62, 56-69, 25-69 and 26-75 years, respectively. The female groups were composed of 55 apparently healthy females, 10 females with coronary heart disease, 73 females with dyslipidemia and 15 females with hypertension with age ranges of 27-65, 33-67, 22-73 and 38-70 years, respectively. Platelet fatty acids levels were found to have no significant difference between the different male groups. In the female groups, the alpha-linolenic acid (ALA) level in hypertension was significantly higher than in coronary heart disease (CHD) (p<0.05), whereas the arachidonic acid (AA) level in hypertension was significantly higher than in the apparently healthy females (p<0.05). No correlation was found between platelet fatty acids and age or anthropometric parameters, which indicate that platelet fatty acids may not depend on either age or anthropometric parameters. Positive correlations were shown between ALA and eicosapentaenoic acid (EPA), AA and docosahexaenoic acid (DHA), ALA and the diastolic blood pressure, DHA and total cholesterol (TC), and between low density lipoprotein choleoterol (LDL-C) and plasma glucose. Negative correlations were shown between LA and EPA, AA and EPA, EPA and DHA, EPA and the systolic blood pressure, and AA and the diastolic blood pressure.
