摘要
为探讨活动平板运动试验中收缩压恢复比对冠心病的诊断价值 ,并从诊断敏感度、特异度、诊断符合率方面与传统的冠心病诊断指标进行对比 ,随机选择了 99例进行了活动平板运动试验与冠状动脉造影的患者 (冠状动脉造影证实 5 6例有冠心病 ,43例无冠心病 ) ,分析其收缩压恢复比与冠心病的关系。结果发现 ,收缩压恢复比 >0 .91诊断冠心病的敏感度、特异度、诊断符合率分别为 5 3 .6%、83 .7%、66.7% ,而传统指标分别为 91.1%、5 5 .8%、75 .8% ;收缩压恢复比 >0 .91在诊断冠状动脉单支、双支和多支血管病变中的敏感度逐渐增加 ,但均低于同组传统指标的诊断敏感度 ;峰值心率与静息心率呈正相关 (r=0 .44 2 ,P <0 .0 0 1) ;峰值收缩压与静息收缩压呈正相关 (r =0 .5 78,P <0 .0 0 0 1)。结果提示 ,运动试验中收缩压恢复比异常可预测冠心病 ,其诊断敏感性低于传统诊断指标 。
Aim To investigate the value of the ratio of systolic blood pressure (rSBP) using treadmill exercise test in diagnosing coronary heart disease (CHD). Methods Ninety-nine patients (56 with CHD, 43 without CHD) underwent treadmill exercise test and selected coronary angiography. Data were analyzed and the sensitivity, specificity, accuracy of rSBP and traditional index were compared. Results The sensitivity, specificity and accuracy of the ratio of systolic blood pressure were 53.6%, 83.7% and 66.7% respectively, while those of the traditional index were 91.1%, 55.8% and 75.8% respectively; The sensitivity of rSBP>0.91 in diagnosing single vessel disease, double or multi-vessel disease increased gradually, lower than that of traditional index. Regression analysis showed a significant relationship between peak HR and pre-exercise HR (r=0.442, P<0.001)and between peak BP and pre-exercise BP (r=0.578, P<0.0001). Conclusions The ratio of systolic blood pressure in exercise test can predict coronary artery disease and its severity. Its sensitivity was lower than that of traditional index, but specificity was higher than it.
