背景：经常食用鱼类与降低冠心病风险有关。然而，这种心脏保护作用背后的生理机制尚不清楚。因此，我们检查了吃鱼者在休息、心算和恢复期间的某些心血管生理变量。调查结果：参与者包括 12 名吃鱼者（每周吃烤鱼超过 3-4 次）和 13 名对照者（每周吃鱼少于 1-2 次）。对收集到的数据进行分析后发现，在休息和心算期间，吃鱼者的心率、血压和脉搏波速度显着低于对照组，射血前期和压力感受反射敏感性显着高于对照组，而且心算后收缩压和平均血压恢复得比对照组更快。结论：这些发现提示了一种可能的生理机制，可以解释为什么经常吃鱼可以降低冠心病风险。
BACKGROUND: Frequent fish consumption is related to a lower risk of coronary heart disease. However, the physiological mechanisms underlying this cardioprotective effect are as yet unknown. We therefore examined certain cardiovascular physiological variables of fish eaters during rest, whilst conducting mental arithmetic, and during recovery.FINDINGS: The participants were 12 fish eaters (eating baked fish more than 3-4 times/week) and 13 controls (eating fish less than 1-2 times/week). Analysis of the collected data revealed that heart rate, blood pressure, and pulse wave velocity were significantly lower and pre-ejection period and baroreflex sensitivity were significantly higher in the fish eaters than in the controls during both rest and mental arithmetic, and that systolic and mean blood pressure recovery from mental arithmetic were faster in the fish eaters than in the controls.CONCLUSIONS: These findings suggest a possible physiological mechanism that may explain why frequent fish consumption reduces coronary heart disease risk.
