男性和女性生理构造迥然不同，就连心脏也存在差异。近日，美国“真实年龄网站”载文，刊出美国心脏外科专家马克·基里洛夫和心脏内科专家斯蒂芬·尼森，总结出的男女心脏的四大不同点。

男性and女性生理构造迥然不同,Even the heart is different.In recent days,The United States"Real age site"Those papers,刊出The United States心脏外科专家马克·基里洛夫and心脏内科专家斯蒂芬·尼森,Sums up the four differences of men and women of the heart.

　　区别1：男性心脏比女性大，女性心血管比男性细。这一差别是雌激素、孕酮激素和雄激素（睾丸激素）所致。雄激素会导致血管扩张，而雌激素则会使血管收缩。因此，女性血管更容易发生血栓，而且在血管成形术或心脏搭桥手术中，血管修复难度更大。血管细还与其他血管疾病有关，比如，偏头痛、狼疮及风湿性关节炎等炎性疾病。这些疾病通常女多男少。

区别1:Men's heart is bigger than women,Women's cardiovascular fine than men.This is a difference between estrogen/孕酮激素and雄激素(testosterone)Caused by the.Androgen can cause vasodilation,While estrogen causes vasoconstriction.so,Women vascular thrombosis is more likely to occur,And in angioplasty or bypass surgery,Vascular repair difficulty is greater.Fine blood vessels also associated with other vascular diseases,Such as the,migraine/Inflammatory diseases such as lupus and rheumatoid arthritis.These diseases usually female more than male.

　　区别2：男性的血栓质硬而广泛，女性则软而少。大多数冠心病的直接原因都是血管栓塞所致，但男性血栓类型及形成位置通常有别于女性。男性心脏病通常多会影响冠状动脉的三大分支（左前降支、左旋支和右冠状动脉），出现广泛的钙化斑（冠状动脉硬化）。而女性心脏病中，则较少出现全面的钙化斑现象，受影响的只是一两条动脉血管。但是，女性患者的血栓通常质地较软，更易发生游离脱落，进而增加心脏病风险。

区别2:Men of blood clots qualitative hard and widely,Women are soft and less.Most of the direct cause of coronary heart disease is caused by the vascular embolism,But the male type and thrombus formation is often different from women.Men usually would affect heart disease three branch of coronary artery(Left anterior descending branch/左旋支and右冠状动脉),In a wide range of calcified plaque(Coronary atherosclerosis).And heart disease in women,Less comprehensive calcified plaque,Only one or two arteries.but,Female patients with thrombosis usually soft texture,Occurred more free fall off,Which increases the risk of heart disease.

　　区别3：男性更容易发生血栓性心脏病，女性则易出现血管痉挛。基里洛夫和尼森的研究发现，在接受心脏导管介入术检查的女性冠心病患者中，30%的人冠状动脉没有发生堵塞，看上去形态正常，远远低于男性。这些女性心脏病发作是由于心脏缺血所致，其具体机理目前尚不完全清楚。不过科学家认为，女性冠心病与心脏动脉血管过细、血管痉挛有关。

区别3:Men are more likely to happen thrombotic heart disease,Women are prone to vasospasm.基里洛夫and尼森的研究发现,Women undergoing cardiac catheter interventional biopsy in patients with coronary heart disease,30% coronary artery didn't happen jam,Looks normal form,Far less than men.These women had a heart attack is caused due to cardiac ischemia,The specific mechanism is not yet fully clear.However, scientists believe,Women with coronary heart disease heart arteries carefully/Vasospasm associated.

　　区别4：女性心脏比男性多一道防线。雌激素对女性心脏具有保护作用，是一道天然防线。然而随着更年期到来，雌激素水平下降，女性心脏得到的保护消减，心脏病危险随着年龄的增大而增加。基里洛夫和尼森建议，步入更年期时，女性应该与医生一起制订心脏健康计划，包括积极运动、低盐低脂饮食、每年测血脂和血压等。▲

区别4:Women's heart is more than the male line of defense.Estrogen plays a protective role for women's heart,Is a natural defense.However, as the menopause,Estrogen levels decline,Women heart protected to reduce,Heart attack risk increases with the increase of age.基里洛夫and尼森建议,When entering menopause,女性应该与医生一since制订心脏健康计划,Including active/Low salt, low fat diet/每年测血脂and血压等.Bring about
