A total of 168 patients admitted to the intensive care department with the diagnosis of unstable angina pectoris (UA), were investigated. Proceeding from the clinical criteria, the patients were divided into 2 groups: with primary (the 1st group) and progressive (the 2nd group) angina. The diagnosis was confirmed by the transesophageal pacing test (TEPT) performed in parallel with two-dimensional echocardiography. Positive TEPT was noted in 84% of the patients in the 2nd group and in 39% of the patients in the 1st group. The volume and expression of ischemia at the height of stimulation (ECTG findings) did not differ in both groups. Some patients with negative TEPT (in both groups) demonstrated an unfavorable time course of volumetric indices: an increase in end systolic and end diastolic volumes, a decrease in the ejection fraction. However, the diagnosis of CHD could not be excluded. Patients need further examination.
共对168名因诊断为不稳定型心绞痛（UA）而入住重症监护病房的患者进行了调查。根据临床标准，将患者分为两组：原发性（第一组）和进行性（第二组）心绞痛。通过与二维超声心动图并行进行的经食管起搏试验（TEPT）来确诊。第二组84%的患者和第一组39%的患者TEPT呈阳性。两组在刺激高峰时的缺血体积和表现（心电图变化结果）无差异。一些TEPT阴性的患者（两组均有）显示出容积指标的不良病程：收缩末期和舒张末期容积增加，射血分数降低。然而，不能排除冠心病的诊断。患者需要进一步检查。
