讨其高血压反应的意义。方法采用无创血压监测仪监测200例受试者心电图踏车负荷试验时的运动血压相关指标,采用超声心动图测量入组患者的左心室几何形态参数,根据相对室壁厚度(RWT)和左心室重量指数(LVMI)明确左室心肌重构的程度,并以最强负荷时收缩压≥200 mmHg和或舒张压≥95 mmHg分为运动血压正常组(A组)和运动高血压组(B组),比较两组间的差异。结果两组在静息血压控制方面无明显差异(P>0.05),但左房内径(LAd)、舒张期室间隔厚度(IVST)、左室舒张期内径(LVDd)、左室后壁厚度(LVPWT)及LVMI比较,差异有统计学意义(P<0.05)。结论运动高血压与心脏损害可能存在关系。临床上应关注运动血压异常反应者。
ObjectiveTo study the clinical relationship between the blood pressure level of exercise primary normotesive subjects and the left ventricle remodeling,and to observe the significance of their hypertension reaction.MethodThe geometric shape parameters of 200 patients sufferring from ECG bicycle loading test were detected by non-invasive blood pressure monitor.All the people were grouped according to their relative wall thickness and left ventricular mass index,and systolic BP≥200mmHg,or diastolic BP≥95mmHg was defined as exercise hypertension,the ventricular geometric shape parameters were compared with normal blood pressure.ResultsThere was no difference of mean blood pressure between exercise induced hypertension and normal blood pressure(P>0.05),while significant differences were found on Lad,LVW,LVPWT,IVST and LVDd between the two groups(P<0.05).ConclusionThe exercise induced normotesive subjects induces the cardiac impairment,this study suggest the intervention of exercise normotesive subjects is so important as static hypertension.
