摘要
【目的】探讨平板运动试验早期心率快速增加与冠心病(coronary heart disease,CHD)的关系。【方法】选择122例进行了平板运动试验与冠状动脉造影的胸痛患者,根据冠脉造影结果,分为冠心病组和非冠心病组,冠心病组中又进一步分为单支病变、双支病变及三支病变组,对比分析各组平板运动试验开始后第1分钟心率的增加量(ΔHR1minute)。【结果】冠心病组ΔHR1minute明显高于非冠心病组(P<0.01),随着冠脉病变支数的增加,ΔHR1minute逐渐增大,组间差异均有显著性(P<0.05)。【结论】冠心病患者运动试验早期心率快速增加,且ΔHR1minute随着冠脉病变支数的增加而增大,提示ΔHR1minute能反映心肌缺血及冠脉病变程度。
[Objective]To explore the correlation between rapidly increased heart rate at onset of treadmill exercise test and coronary heart disease. [Methods]One hundred twenty two patients underwent treadmill exercise test and coronary angiography. The patients were divided into coronary heart disease （CHD） group and non-CHD group according to the results of coronary angiography. The patients of CHD group was divided into single-vessel disease group, double-vessel disease group and triple-vessel disease group. The increased heart rate during the first minute （△HR1minute） of treadmill exercise test and the extent of coronary artery lesion were analyzed. [Results]△HR1ninute in CHD group was significantly higher than that in non-CHD group（ P 〈0.01）. △HR1minute had an increasing trend with the number of coronary artery lesion. [Conclusion]The heart rate of patients with CHD increases rapidly at onset of treadmill exercise test. And △HR1minute has an increasing trend with the number of coronary artery lesion . These Results indicate that △HR1minute can estimate the extent of myocardial ischemia and coronary artery lesion .
