Abstract

Background: The relationship between serum fatty acid levels and the extent of coronary plaques and calcification was examined in patients with acute myocardial infarction (AMI). Methods and Results: The serum levels of the n-3 polyunsaturated fatty acids (eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)) and the n-6 polyunsaturated fatty acids (arachidonic acid (AA) and dihomogamma-linolenic acid (DGLA)) were determined using gas chromatography on admission of 95 consecutive patients with their first AMI and 17 controls. Using multidetector-row computed tomography, soft plaques and calcification lesions were scored according to the extent of coronary involvement. Serum logarithmic transformed (log) EPA and logDHA levels were inversely correlated with soft plaque scores (r=-0.546, p<0.0001 and r=-0.377, p<0.0001, respectively). Serum logAA and logDGLA levels were not significantly correlated with soft plaque scores. Serum logEPA and logDHA levels were significantly, but weakly, correlated with calcification scores. Multivariate analysis with clinical characteristics and risk factors selected serum n-3 polyunsaturated fatty acid levels as independent factors associated with the extent of coronary soft plaques. Conclusion: The present study demonstrates a significant correlation between serum n-3 polyunsaturated fatty acid levels and the extent of coronary soft plaques and calcification in AMI patients.
