本文前瞻性地评价严格分组的不稳定心绞痛(UA)患者,并将ST段偏移方向与冠状动脉(CA)解剖相联系.方法:2年中连续住院的UA患者46例(近期心绞痛发作或者原心绞痛的频度或持续时间增加而住院;住院期休息时发生心绞痛,其ST段增高或降低>1mm).他们符合:(1)至少有一次胸痛发作时,其心率增加不超基础心率的10%和<100次/分,收缩和舒张压的增高不超过对照值的10%.心率和血压的测定在病人诉说胸痛后几秒至1分钟内进行;(2)同一次住院期完成CA造影、明显的梗阻指内腔直径狭窄>50%.左CA主干明显梗阻系分出左前降支或回旋支之前,近端管腔直径减少≥ This prospective evaluation of patients with unstable angina pectoris (UA) under strict classification and ST-segment migration direction associated with coronary artery (CA) anatomy.Methods: 2 consecutive hospitalized UA patients 46 cases (recent angina pectoris or Angina pectoris was hospitalized with increased or decreased duration of angina, with an increase or decrease in ST-segment of> 1 mm during hospitalization.) They met: (1) at least one episode of chest pain, their heart rate did not increase beyond the basal heart rate 10% and <100 beats / min, systolic and diastolic blood pressure did not increase by more than 10% of the control value. Heart rate and blood pressure were measured within a few seconds to 1 minute after the patient complained about chest pain; (2) Contrast, the obvious obstruction refers to the lumen diameter stenosis> 50%. Left CA main obstruction obstruction left anterior descending branch or circumflex artery before the proximal lumen diameter reduction ≥
