We have found that aspirin lowers elevated serum lipoprotein(a) [Lp(a)] levels via reduction of the transcriptional activity of apolipoprotein(a) [apo(a)] gene with suppression of apo(a) mRNA expression. In the present study, we evaluated the effect of aspirin treatment on serum Lp(a) level and analyzed its relation to type of apo(a) isoform. Serum levels of Lp(a) were measured by turbidimetric immunoassay before and after the oral administration of aspirin therapy (81 mg/day) in 57 patients with coronary artery disease or cerebral infarction. Apo(a) isoforms were determined by immunoblotting method. In patients with high serum Lp(a) levels (more than 30 mg/dl), aspirin reduced serum Lp(a) levels to approximately 80 % of the baseline after one month. Their levels sustained significantly low even after six months. The effect of aspirin in reducing elevated serum Lp(a) levels were stronger in patients with smaller-sized type or double-band type of apo(a) isoforms. The transcriptional efficiency of apo(a) gene is thought to be increased in patients with these apo(a) isoforms. Therefore, these findings suggest that aspirin reduces apo(a) gene transcription preferentialy in patients with high transcriptional efficiency of this gene.
