目的 探讨健康航海人员 2 4h动态血压监测 (ABPM)各参数的正常值。方法 用标准水银柱式血压计测量左上臂坐位血压 ,对 94名血压 <140 / 90 mm Hg的健康航海人员 ,行 2 4h ABPM。结果 94名健康航海人员 ABPM各参数均值 (上限值 )分别为 :2 4h动态血压 116 .10 (12 7.8) / 74.36(83.6 ) mm Hg,白天血压 119.13(131.6 ) / 76 .82 (86 .0 ) mm Hg,夜间血压 10 5 .5 1(119.9) / 6 5 .97(77.8)mm Hg。≥ 35岁组 2 4h平均舒张压高于 <35岁组 (P<0 .0 1)。不同海域的航海人员 2 4h ABPM各相应参数均值无明显差别 (P均 >0 .0 5 )。结论 建议以 2 4h动态血压均值 <12 8/ 84mm Hg,白天均值 <132 / 86 m m Hg,夜间均值 <12 0 / 78mm Hg,夜间血压下降率≥ 10 %和血压负荷值 <15 %作为暂定健康航海人员 2 4h动态血压正常参考值标准。
Objective To investigate the normal values of 24-h ambulatory blood pressure monitoring (ABPM) for healthy sailors. Methods Blood pressure was measured in the upper left arm using a standard mercury sphygmomanometer. Twenty-four healthy sailors with blood pressure <140/90 mm Hg were enrolled for 24 h ABPM. Results The average ABPM parameters of 94 healthy seafarers were as follows: the mean arterial blood pressure at 24 hours was 116.10 (12 7.8) / 74.36 (83.6) mm Hg, and the daytime blood pressure was 119.13 (131.6) / 76.82 (86. 0) mm Hg, nocturnal blood pressure 105.51 (119.9) / 6 5 .97 (77.8) mm Hg. The mean diastolic blood pressure at 24 hours in ≥ 35 years old group was higher than that in <35 years old group (P <0.01). There was no significant difference between the corresponding parameters of 24 h ABPM for sailors in different sea areas (P> 0.05). Conclusions The proposed 24-h ambulatory blood pressure mean <12 8/84 mm Hg, daytime mean <132/86 mm Hg, nocturnal mean <12 0/78 mm Hg, nocturnal hypotension> 10%, and blood pressure load <15% Healthy sailing personnel 2 4h ambulatory blood pressure normal reference standard.
