We evaluated the usefulness of a decrease in the average peak velocity from 4 to 10 minutes after infusion of dipyridamole for detecting myocardial ischemia in 50 patients, including patients with a prior myocardial infarction. The decrease in the average peak velocity from 4 to 10 minutes associated with vertical steal and combined with a coronary flow reserve of < 1.6 had a high predictive value for myocardial ischemia in patients with or without prior myocardial infarction.
我们评估了在50例患者（包括有心肌梗死病史的患者）中，输注双嘧达莫后4至10分钟平均峰值速度的降低对于检测心肌缺血的有用性。与垂直窃血相关且伴有冠状动脉血流储备<1.6的4至10分钟平均峰值速度的降低，对于有无心肌梗死病史的患者心肌缺血均具有较高的预测价值。
