【摘要】 目的探讨三磷酸腺苷介入心肌灌注断层显像(ATP-MPI)诊断老年人冠心病(CAD)的价值和安全性。方法49例无心肌梗死病史的老年冠心病待查患者(年龄≥60岁,平均年龄66.33岁)行ATP-MPI和冠状动脉造影(CAG)。结果ATP介入试验过程中,共有19种不良反应表现,但这些表现均在停止注射ATP后2分内自行终止,无一例病人因不良反应中断ATP介入试验。ATP-MPI诊断老年人冠心病的敏感性90.0%,特异性89.5%,准确性89.8%;诊断冠状动脉狭窄的敏感性84.1%,特异性90.1%。结论ATP介入心肌灌注断层显像是诊断老年冠心病准确性和安全性均很高的无创检查方法。更多还原

【Abstract】 Objective To evaluate the value and safety of ATP stress myocardial perfusion tomographic imaging in detection of coronary disease(CAD) in the elders.Methods Forty-nine patients ≥60 years old without myocardial infarction were included in the research.All patients underwent ATP-MPI and coronary angiography within 2 months.Results There were 19 kinds of side effects occur during ATP stress.However,no ATP stress was interrupted by the side effects,and no patients needed special therapy on the side effects.The sensitivity,specificity and accuracy of ATP stress in detection of coronary artery disease were 90.0%,89.5%,and 89.8%,respectively.Conclusion ATP stress myocardial perfusion tomography imaging is a good noninvasive method with high diagnostic accuracy and safety in detection of coronary artery disease in the elders.更多还原
