雌激素除对生殖泌尿系统的生理功能有影响以外,对机体其它系统的功能和代谢也有调节。随着对孕期心脏功能变化机理研究的进展,逐渐了解到雌激素对非孕期妇女心脏功能也具有影响。表现为左室舒张末期容积、心输出量和射血分数增加。其作用机理可能通过肾素-血管紧张素-醛固酮系统或强心甙样作用或通过特异性受体影响心肌细胞的代谢而改变心肌活动。 In addition to estrogen on the physiological function of the genitourinary system, the body’s other systems function and metabolism are also regulated. With the progress of research on the mechanism of heart function changes during pregnancy, it is gradually realized that estrogen also has an impact on heart function in non-pregnant women. The performance of left ventricular end-diastolic volume, cardiac output and ejection fraction increased. Its mechanism of action may be through the renin - angiotensin - aldosterone system or cardiac glycoside-like effect or through specific receptors affect the metabolism of myocardial cells to change myocardial activity.
