冠状动脉慢血流患者腺苷负荷心肌灌注显像及预后研究

Adenosine Stress Myocardial Perfusion Imaging and Prognosis Study in Patients with Coronary Slow Flow

目的:探讨冠状动脉慢血流患者的心肌血流灌注情况及预后。材料与方法:对我院30例冠状动脉慢血流患者及30例冠状动脉血流正常者行腺苷负荷心肌灌注显像并随访1年心脏事件发生率,对两组结果进行分析比较。结果:慢血流组腺苷负荷心肌灌注显像阳性率80%,比正常血流组明显增多,随访1年发现慢血流组心脏事件发生率明显高于正常血流组。结论:冠状动脉慢血流患者腺苷负荷心肌灌注显像阳性率高,且其较冠状动脉血流正常患者发展为冠心病及急性心肌梗死的风险增加,应引起临床重视。

Purpose： To investigate the myocardial perfusion and prognosis in patients with coronary slow flow（CSF）. Materials and Methods： 30 patients with coronary slow flow and 30 patients with nomal coronary flow（NCF） were enrolled, all the patients underwent adenosine stress myocardial perfusion imaging, and the cardiac events were observed in 1 year fol- low-up. Results： The positive rate of CSF group in adenosine stress myocardial ischemia was 80%, which was significantly higher than NCF group, followed up for 1 year found that the incidence of cardiac events in CSF group was significantly higher than NCF group. Conclusion： the patients with CSF had high positive rate in adenosine stress myocardial perfusion imaging, and were more easily to get to coronary artery disease and acute myocardial infarction than NCF, we should pay more attention to them.
