【摘要】 目的观察血压正常而有高血压家族史者平板运动试验时的舒张压变化。方法回顾分析345例完成平板运动试验者的临床资料,分成观察组(83例,血压正常但有高血压家族史)、高血压组(141例,有或无高血压家族史)、正常组(121例,血压正常且无高血压家族史)。记录静息仰卧及直立位舒张压,运动中3min及运动峰值舒张压,运动后1min、3min及5min仰卧位舒张压。结果观察组与高血压组之间运动舒张压变化呈正相关(r=0.884,P=0.019),而观察组与正常组无明显相关性。观察组运动峰值舒张压与运动后1min舒张压的差值为5.15(95%CI:4.58～5.72)mm Hg,高血压组为5.48(95%CI:5.10～5.86)mm Hg,正常组0.44(95%CI:0.09～0.79)mm Hg。结论与高血压患者相似,有高血压家族史而血压正常者运动时舒张压增高。更多还原

【Abstract】 Objective To observe diastolic blood pressure(BP) changes during treadmill exercise test in subjects with normal BP and family history of hypertension(FHP). Methods The clinical data of 345 subjects underwent treadmill exercise test were retrospectively analyzed. Of them, 83 cases had normal BP and FHP(observation group), 141 cases were hypertensive with or without FHP(hypertensive group), 121 cases had normal BP and no FHP(normal group). Supine and upright diastolic BP at rest, diastolic BP at 3 min of exercise and at peak exercise, and supine BP at 1 min, 3 min, 5 min after exercise were recorded. Results There was a positive correlation of diastolic BP changes between the observation group and the hypertensive group(r=0.884, P=0.019), but no significant correlation between the observation group and the normal group. The difference of diastolic BP at peak exercise and at 1 min after exercise was 5.15(95%CI:4.58～5.72) mm Hg in the observation group, 5.48(95%CI:5.10～5.86) mm Hg in hypertensive group and 0.44(95%CI:0.09～0.79)mm Hg in normal group. Conclusion Diastolic BP increases during exercise in subjects with normal BP and FHP as in the case of hypertensive patients.更多还原
