Accordingly , pressing of arteries and veins increases besides wanting to consider aorta valve shuts the common cause such as not complete , hyperthyroidism , consider to whether be put in arteriosclerosis to send the element that flexibility drops even 因此，脉压增大除了要考虑到主动脉瓣关闭不全、甲状腺机能亢进等常见原因外，还要考虑是否存在动脉硬化致弹性下降的因素。
Former for sound of of one mind , basically originate systaltic when the oscillatory ; latter that mitral valve and tricuspid shut generation is disloyalty sound , basically originate diastolic when the vibration that aorta valve and pulmonary artery valve shut a generation 前者为第一心音，主要来源于心脏收缩时二尖瓣和三尖瓣关闭产生的振动;后者为第二心音，主要来源于心脏舒张时主动脉瓣和肺动脉瓣关闭所产生的振动。
Two recent new england journal of medicine studies confirm preious findings associating pergolide with increased chance of regurgitation ( backflow of blood ) of the mitral , tricuspid , and aortic ales of the heart . ale regurgitation is a condition in which ales don ' t close tightly , allowing blood to flow backward across the ale 《新英格兰医学杂志》最近的两篇文章证实了以前发现的有关培高利特增加心脏主动脉瓣、二尖瓣膜和三尖瓣血液回流可能性。
Conclusion : mitral and aortic valves were vulnerable to calcification which was the major change of heart valve in patients with crf on maintenance hemodialysis , the degree of calcification was closely related to hyperphosphoremia , secondary hyperparathyroidism and a longer period of hemodialysis 结论:慢性肾功能衰竭维持性血液透析患者心脏瓣膜病变均以钙化为主,尤以二尖瓣、主动脉瓣易发,且钙化程度与钙磷乘积、继发性甲状旁腺机能亢进和血液透析年限密切相关。
Results : among 64 cases with crf , the echocardiographic findings were mitral valve calcification ( mac ) in 9 cases , mitral regurgitation ( mr ) in 5 cases , mitral stenosis ( ms ) in 2 cases , aortic valve calcification in 12 cases , aortic regurgitation in 7 cases , combined mitral and aortic valves cacification in 5 cases , respectively 结果: 64例患者中发现二尖瓣钙化9例,二尖瓣返流5例,二尖瓣面积减少致狭窄2例,主动脉瓣钙化12例,主动脉瓣返流7例,二尖瓣并发主动脉瓣钙化3例。
