摘要
目的分析冠状动脉心肌桥患者的临床特点、冠状动脉造影结果及随访和治疗情况。方法2001-01～2004-12对北京协和医院心内科经冠状动脉造影诊断冠状动脉心肌桥的52例患者,分析其临床表现特点及冠状动脉造影结果等,并对患者进行门诊或电话随访,了解治疗情况和预后。结果52例患者中男性多于女性,平均年龄(53±12)岁,均有不同程度的胸部不适症状。冠状动脉造影显示心肌桥多位于前降支中段,收缩期管腔狭窄30%～99%。住院期间50例患者应用药物治疗,2例患者行冠状动脉内支架置入术。共随访40例患者,平均随访(1.9±1.1)年。其中22例患者仍有症状,25例患者出院后需继续药物治疗,随访期间无患者死亡;1例行冠状动脉内支架置入术的患者,术后3.3年复查冠状动脉造影发现支架内再狭窄50%。结论冠状动脉心肌桥患者多表现为非典型心绞痛症状,多数患者接受药物治疗,冠状动脉支架置入术可使心肌桥内冠状动脉血流恢复正常,心肌桥患者通常预后良好。
Objective To investigate the clinical features and the findings of coronary angiography, the treatment and prognosis of patients with myocardial bridge. To increase our knowledge on myocardial bridge. Methods Fifty two patients were diagnosed as myocardial bridge by coronary angiography in our hospital from January 2001 to December 2004. Angiographicalty,systolic compression of the arterial lumen that disappears during diastole was considered diagnostic of a myocardial bridge. Analyse the clinical features and therapy condition. Follow patients by telephone or clinical visits. Results Our study included fifty two patients. Male patients weremore than female ones and the average age was 53 ± 12 years old. Myocardial bridge was the most common in the middle segment of the left anterior descending artery. Majority of the patients took medication, and 2 of them were treated with intracoronary stent implantation. Forty patients were followed. During a mean 1.9±1.1 years follow - up period, there was no cardiac death. 25 of the patients required medication, and 1 of 2 patients who underwent stent implantation had in - stent restenosis at 3. 3 years. Conclusion Patients with myocardial bridge may present with atypical chest pain. Major patients with myocardial bridge are treated with medication, and stent implants may improve patients＇ symptoms. The prognosis of the patients with myocardial bridge is usually good.
