The study explored the relationship between time- and frequency-domain indices of cardiac autonomic control and 24 h blood pressure variability (BPV) in a sample of healthy men and women. Vagally mediated cardiac control was inversely related to 24 h BPV, and measures of cardiac autonomic control were better predictors of systolic BPV in men and better predictors of diastolic BPV in women. These findings may help researchers to understand the disparity in cardiovascular disease morbidity and mortality between men and women.
该研究在一组健康男性和女性样本中，探讨了心脏自主控制的时域和频域指标与24小时血压变异性（BPV）之间的关系。迷走神经介导的心脏控制与24小时BPV呈负相关，心脏自主控制指标对男性收缩压BPV的预测效果更好，对女性舒张压BPV的预测效果更好。这些发现可能有助于研究人员理解男性和女性在心血管疾病发病率和死亡率上的差异。
