本研究比较了不同种族和原发性高血压家族史的6- 15岁男性对电子游戏挑战和前额冷应激的血压、心率、每搏输出量、血管阻力和心输出量反应。控制年龄,黑人男孩的收缩压和舒张压比他们的白色同龄人高。阳性家族史的儿童在基线时被发现有较高的心输出量和体表面积指数的每搏输出量。控制基线血流动力学反应和年龄,阳性家族史儿童表现出更大的全身血管阻力和收缩压和舒张压的增加和更大的心率下降到冷应激。阳性家族史儿童在视频游戏和冷应激阶段表现出更大的心脏指数下降。研究结果的影响和未来的研究方向进行了讨论。
: This study compared blood pressure, heart rate, stroke volume, vascular resistance, and cardiac output responses to a video game challenge and forehead cold stressor in 6-to 15-year-old males who varied in ethnicity and family history of essential hypertension. Controlling for age, significant baseline differences were obtained with black boys exhibiting higher systolic and diastolic pressures than their white cohorts. Positive family history children were found to have higher cardiac outputs and stroke volumes indexed by body surface area during baseline. Controlling for baseline hemodynamic responses and age, positive family history children exhibited greater increases in systemic vascular resistance and systolic and diastolic pressure and greater decreases in heart rate to the cold stressor. The positive family history children exhibited greater decreases in cardiac index during both the video game and cold stressor phases. Implications of the findings and directions for future research are discussed.
