目的 探讨运动后收缩压异常升高对冠心病的诊断价值 ,以及高血压对其诊断准确性的影响。方法 88例先后行平板运动试验和冠脉造影的患者 ,根据高血压的有无和冠脉造影结果分组。以运动后恢复早期 6min内 ,收缩压后期比前期升高≥ 10mmHg为收缩压异常升高的阳性判定标准。结果 收缩压异常升高诊断冠心病的敏感性、特异性、准确性 ,高于ST段压低标准 ;其敏感性与冠脉病变程度成正比 ,其升高值亦与冠脉病变成正相关 ;在非高血压组其诊断的准确性较高 ,对合并高血压的患者 ,两指标联用的诊断准确性最高。结论 运动后收缩压异常升高可作为诊断冠心病的一个有效指标
Objective To investigate the diagnostic value of abnormal systolic blood pressure after exercise on coronary heart disease and the impact of hypertension on its diagnostic accuracy. Methods Totally 88 patients underwent treadmill exercise test and coronary angiography were divided into groups according to the presence or absence of hypertension and coronary angiography. In the early 6min after exercise recovery within the late systolic blood pressure increased than the previous period ≥ 10mmHg for abnormal positive systolic blood pressure increased the standard. Results The sensitivity, specificity and accuracy of systolic blood pressure in diagnosing CHD were higher than those in ST-segment depression. The sensitivity was proportional to the severity of coronary artery disease. The increase was also positively correlated with coronary artery disease ; In non-hypertensive group its diagnostic accuracy is higher, for patients with hypertension, the two indicators combined with the highest diagnostic accuracy. Conclusion The abnormal systolic blood pressure after exercise can be used as an effective indicator for the diagnosis of coronary heart disease
