心脏起搏术后患者发生心绞痛的情况分析

目的分析心脏起搏术后患者心绞痛的发生情况。方法 35例起搏器术后一年内并发心绞痛的为心绞痛组,选取同期的495例永久心脏起搏患者为非心绞痛组,比较两组的一般情况。并对不同起搏原因及不同起搏方式的心绞痛发作情况进行比较。结果与非心绞痛组比较,心绞痛组年龄、吸烟、性别构成无差异,但合并高血压、糖尿病、高脂血症比例较高。因房室传导阻滞(AVB)行心脏起搏者较因病窦综合征起搏者术后发生心绞痛比例高(15.4%vs 1.8%,P<0.001),而安置VVI者与DDD者心绞痛发生率相似(6.7%vs 6.3%,P>0.05)。结论起搏术后发生心绞痛患者多合并多种冠心病危险因素,AVB者术后心绞痛发生率高。

Analysis of angina pectoris after pacemaker implantation.

Objective To observe the attack of angina pectoris after permanent pacemaker implantation. Methods Thirty-five patients with angina pectoris after pacemaker implantation within 1 year were allocated to angina pectoris group, while 495 patients without angina pectoris were allocated to non-angina pectoris group. General characters of both groups were compared. Incidence of angina pectoris in different pacing cause and different pacing mode were compared. Results There was no difference of age, smoking or sex constituent between two groups, but the angina pectofis group had more hy- pertension, diabetes mellitus or hyperlipidemia than non-angina pectoris group. The patients with atrioventricle block（AVB） had more occurrence of angina pectoris than the patients With sick sinus syndrome after pacemaker implantation（ 15.4% vs 1.8 % , P 〈 0.001 ） , while patients receiving VVI or DDD pacemaker had similar occurrence of angina pectoris （6.7 % vs 6. 3% ,P 〉 0.05 ）. Conclusion Patients developing angina pectoris after pacemaker implantation usually accompany with several risk factors of coronary heart disease ,patients with AVB often has coronary heart disease and develop angina peetoris easily.
