心率与高血压患者冠心病的相关性探讨

Correlation of Resting Heart Rate and Coronary Heart Disease in Patients with Hypertention

目的观察静息心率与高血压患者冠心病及冠状动脉狭窄程度的关系。方法分别观察208例入选者中无高血压病与高血压病患者的静息心率,据冠状动脉造影结果将其分为对照组及冠心病组。结果高血压患者冠心病组静息心率显著高于对照组(78.67±11.04)次/分vs(70.45±10.47)次/分(P<0.01);无高血压病者冠心病组静息心率与对照组无显著差别(70.49±11.28)次/分vs(75.44±12.84)次/分(P>0.05)。结论静息心率是高血压病患者冠心病的危险因子,与冠心病发生、发展及预后有关,对于高血压病患者降低静息心率较非高血压病者具有更重要的意义。

Objective To explore the relationship between resting heart rate（RHR） and coronary heart disease（CHD） in patients with hypertension. Methods The RHR was detected in 97 patients with hypertension and 101 patients without hypertension, both were divided into control group and CHD group by the outcomes of coronary angiography. Results In the patients with hypertension,the RHR of CHD group was significantly higher than that in control group （78.67 ± 11.04 bpm vs 70.45 ± 10.47 bpm, P 〈 0.01 ）. No significant difference was found between RHR and CHD groups in the patients without hypertension（P〉 0.05）. Conclusion The RHR is related to CHD in the patients with hypertension, and it is more important to control the RHR in the patients with hypertension than that in those without hypertension.
