We investigated the role of the angiotensinogen (AGT) gene M235T polymorphism in determining blood pressure (BP) response to moderate intensity exercise in a 6-yr randomized controlled trial in 140 middle-aged men. Sitting, supine, and standing blood pressures were measured annually. Of the randomized men, 86% participated in the trial for 6 yr. Submaximal cardiorespiratory fitness increased by 16% in the exercise group. In the M homozygotes, sitting systolic BP decreased by 1.0 mmHg in the exercise but increased by 14.6 mmHg in the reference group (P = 0.007 for net effect). Sitting and supine diastolic BP decreased by 6.2 and 3.3 mmHg in the exercise but increased by 2.8 and 3.2 mmHg in the reference group (P = 0.026 and 0.024 for net effects), respectively. Regular moderate intensity exercise attenuates aging-related increase in systolic BP and decreases diastolic BP among the M homozygotes of the AGT gene M235T polymorphism.
在一项针对140名中年男性的为期6年的随机对照试验中,我们研究了血管紧张素原(AGT)基因M235T多态性在决定血压(BP)对中等强度运动反应中的作用。每年测量坐位、仰卧位和站立位血压。在随机分组的男性中,86%参与试验达6年。运动组的次最大心肺适能提高了16%。在M纯合子中,运动组坐位收缩压下降了1.0 mmHg,而对照组上升了14.6 mmHg(净效应P = 0.007)。运动组坐位和仰卧位舒张压分别下降了6.2和3.3 mmHg,而对照组分别上升了2.8和3.2 mmHg(净效应P分别为0.026和0.024)。规律的中等强度运动可减弱AGT基因M235T多态性M纯合子中与衰老相关的收缩压升高,并降低舒张压。
