为了确定实时二维超声心动图（2-D echo）在不稳定型心绞痛中的价值，分析连续短轴2-D echo记录的局部壁运动，并根据患者出院后12周的临床状态对异常运动的段积分进行汇总比较和分类。19例符合不稳定型心绞痛标准并对药物治疗有反应的男性患者在入院和出院48小时内进行了二维超声检查。入院时二维回声评分异常的11例患者中，5例患者评分降低，6例患者出院时评分相似或升高。入院时得分为零的8名患者中，有6名在出院时得分为零。随访时，11例患者有轻微或无心绞痛（1组），8例患者心绞痛恶化或复发不稳定型心绞痛（2组）。出院时，二维超声检查显示，1组患者的异常评分均降低或为零，而2组患者的异常评分保留或升高。本研究表明，在不稳定型心绞痛患者中，二维超声可识别暂时性和持续性异常。在预后良好的患者中，异常节段性壁运动是短暂的或不存在的，而在预后较差的患者中，异常节段性壁运动恶化或保持异常。
To determine the value of real-time, two-dimensional echocardiography (2-D echo) in unstable angina, regional wall motion on serial short-axis 2-D echo recordings was analyzed and summed segment scores of abnormal motion were compared and classified according to each patient's clinical status 12 weeks after hospital discharge. Nineteen male patients who fulfilled criteria for unstable angina and responded to medical therapy underwent 2-D echo study within 48 hours of admission and discharge. Of 11 patients with abnormal 2-D echo scores on admission, five patients had reduced scores and six patients had similar or increased scores at discharge. Six of eight patients who had scores of zero on admission had scores of zero at discharge. At follow-up, 11 patients had minimal or no angina pectoris (group 1), and eight patients had worsening angina or recurrent unstable angina (group 2). At discharge, 2-D echo studies showed that all group 1 patients had reduced or zero scores, while group 2 patients retained or increased their abnormal scores. This study shows that in patients with unstable angina, both transient and persistent abnormalities can be identified by 2-D echo. Abnormal segmental wall motion was transient or absent in patients with a good outcome, and worsened or remained abnormal in patients with a poor outcome.
