原发性高血压冠心病患者静息心率与心脏变时性功能不全的临床研究

摘要

Objective :To study the change and clinical evaluation of the resting heart rate (RHR) and chronotropic in-competence(CI) in the patients with original high-blood and coronary heart disease(CHD) .Methods :136 patients with original high-blood and coronary heart disease and 90 healthy subjects in the control group all had abnormal 12-lead Holter ,RHR and CI were investigated and analysing .Results:The value of the RHR and CI of CHD was significantly higher than the healthy group .The CHD in the treadmill test (TET) had more probability in positive than healthy sub-jects .The difference was statistically significant .Conclusion:The RHR and CI are of great value in the diagnosis of cor-onary artery lesions .Pay attention to the controlling of RHR is the guidance of prevention on CHD .The RHR and CI can be the index of diagnosing CHD and the significant index of prognostic .%目的：研究原发性冠心病患者静息心率与心脏变时性功能的变化及临床意义。方法：选择住院原发性高血压冠心病患者136例与90例健康人作对照比较，据24h动态心电图（Holter ）记录，记录静息心率（Resting heart rate ， RHR）和心脏变时性功能不全（Chronotropic incompetence ，CI）的指标，分别分析静息心率和心脏变时性功能不全的两组间差别及相关性。结果：原发性高血压冠心病组静息心率明显高于对照组；心脏变时性功能不全明显高于对照组；平板运动实验阳性率明显高于对照组，差异有统计学意义。结论：静息心率和心脏变时功能不全可以作为诊断冠脉病变的独立敏感指标；关注静息心率的控制是高血压冠心病的防治方向，静息心率和心脏变时功能，可以作为预后判断的重要指标。
