科学家在心脏起搏基因中发现性别差异,解释了不同的心率和风险。 Scientists find gender differences in heart's pacemaker genes, explaining varied heart rates and risks.

俄亥俄州立大学的研究人员发现,由于不同的基因表达方式,心脏的天然心脏起搏器 -- -- 硅酸盐结点 -- -- 在男子和妇女中的运作方式不同。 Researchers at Ohio State University found that the sinoatrial node, the heart's natural pacemaker, operates differently in men and women due to distinct gene expressions. 由于TBX3和HCN1等基因的缘故,妇女心脏病发病率更快,而男性则更容易患心脏病,如与炎症有关的基因网络造成的轻微纤维发炎。 Women have faster heart rates due to genes like TBX3 and HCN1, while men are more prone to heart rhythm disorders like atrial fibrillation due to gene networks linked to inflammation. 这种发现可能导致对心脏节奏紊乱进行更个性化的治疗。 This discovery could lead to more personalized treatments for heart rhythm disorders.
