摘要
为探讨静息心率在冠心病中的变化及其临床意义。对 119例冠心病患者同时进行冠状动脉 (简称冠脉 )造影及静息心率的测定。结果 :冠心病组静息心率显著高于正常对照组 (79.11± 7.86vs 71.0 5± 6 .87次 /分 ,P <0 .0 5 ) ,在急性心肌梗死 (86 .77± 6 .76 )及不稳定型心绞痛组 (78.91± 8.30 )静息心率升高更明显 (P <0 .0 5 ) ,相关分析显示静息心率与冠脉的狭窄程度呈正相关 ,其中急性心肌梗死组静息心率与左前降支的狭窄程度呈显著正相关 ,P <0 .0 5。结论 :静息心率可能与动脉硬化的发生及冠心病的预后有关。
To investigate changes and significance of resting heart rate in patients with coronary heart disease (CHD),119 CHD patients were examined resting heart rate and coronary arteriography.Result:the resting heart rate was significantly increased in CHD patients compared with control group (79.11±7.86 vs 71.05±6.87 bpm, P<0.05 ) and increased much more in acute myocardial infarction group(86.77±6.76 bpm) and unstable angina pectoris group(78.91±8.30 bpm).Correlation analysis showed that resting heart rates correlated positively to the level of coronary artery stenosis.Conclusion:Resting heart rate may play a role in both the initiation and progression of CHD and atherosclerosis.
