潘生丁-超声心动图试验为评价冠状动脉疾病有效方法之一.但仅呈现“有或无”的反应(阳性对阴性).而运动负荷试验则可借缺血发作时心脏作功的阈值将缺血反应分级.为此,作者企图以潘生丁-超声(心动图)试验区分冠扶动脉供血不足的级别,提出以下几项指数:出现活动失调(阳性及阴性反应);诱发缺血所需潘生丁的剂量以及用小剂量潘生丁出现不协调活动的时间.并将极量运动试验或“缺血”时的心率-压力乘积作为对照参考指标.方法:141例劳力性心绞痛病人,进行运动负荷、潘生丁-超声和冠状动脉造影检测.平均年龄55岁.凡静息时有心绞痛或合并有高血压、传导障碍、左室肥厚、二尖瓣脱垂者不列在内.试前至少停药 Dipyridamole - Echocardiography is one of the most effective methods for assessing coronary artery disease, but presents only a “yes or no” response (positive vs negative), whereas exercise stress tests may be based on the threshold of cardiac work during an ischemic attack To classify the ischemic response, the authors attempted to differentiate the grade of coronary artery insufficiency from the dipyridamole-echocardiography (EKG) trial by proposing the following indices: An activity disorder (positive and negative); Dipyridamole dosage and duration of uncoordinated activity with small doses of dipyridamole, and the heart rate-pressure product of the maximal exercise test or “ischemia” was used as a control reference index.Methods: 141 patients with exercise-induced angina pectoris Load, dipyridamole - ultrasound and coronary angiography, with an average age of 55. Any rest at the time of angina pectoris or hypertension, conduction disorders, left ventricular hypertrophy, mitral valve prolapse are not included. medicine
