中国循环杂志99zk35 目的：本研究通过观察经皮冠状动脉腔内成形术(PTCA)后血浆内皮素(ET)及前列环素(PGI2)的代谢产物6-酮-前列腺素F1α(6-酮-F1α)水平的改变，探讨其在PTCA后冠状动脉收缩中的可能作用。
方法：对21例冠状动脉造影及19例PTCA患者检测血浆ET和PGI2的代谢产物6-酮-F1α的变化。
结果：单纯冠状动脉造影的患者血浆ET及6-酮-F1α在手术前后无明显的变化(P>0.05),而PTCA后24小时血浆ET和6-酮-F1α较术前明显升高(P<0.05),术后1周又复降至接近术前水平(P>0.05)。单支血管和多支血管的PTCA，血浆ET和6-酮-F1α浓度变化比较均无统计学差异(P>0.05)。
结论：在PTCA 24小时后应注意防止血小板聚集和血栓形成，术后1周内最好服用预防冠状动脉痉挛药物。

Objective: To investigate the action of endothelin (ET) and a metabolite of prostacyclin, 6-keto-F1α after percutaneous transluminal coronary angioplasty in coronary constriction.
Methods: Plasma ET and a metabolite of prostacyclin 6-keto-F1α, levels were tested in 21 cases undergoing coronary angiography and 19 patients undergoing percutaneous transluminal coronary angioplasty.
Results: Plasma ET and 6-keto-F1α levels did not change significantly before and after coronary angiography (p>0.05), however they were significantly increased 24 hours after percutaneous transluminal coronary angioplasty (PTCA) (p<0.05). The levels decreased close to baseline within a week after PTCA (p>0.05). No significant differences in plasma ET and 6-keto-F1α levels between single and multivessel PTCA were observed after the procedure (p>0.05).
Conclusion: It was essential to protect from platelet aggregation and thrombosis from 24 hours after PTCA and to take prophylactic drugs to avoid coronary spasm in the first week after PTCA., http://www.100md.com
