Heart failure心力衰竭
Heart failure does not mean that the heart has stopped or that it is about to do so. Instead it is when the heart cannot pump blood around the body efficiently. This means that the tissue of the body is not getting enough oxygen and nutrients to enable it to function properly.心力衰竭，并不意味着心脏已停止或认为它是关于这样做。相反，它是当心脏不能泵血液周围组织有效率，这意味着该组织的机构是没有获得足够的氧气和养分，使它的功能。 In addition, waste materials cannot be transported properly to the lungs and kidneys for excretion.在此外，废料不能妥善运至肺部和肾脏为排泄。 The result is that fluid builds up in the lungs and tissue.结果是流体积聚在肺部和组织。
Heart failure is caused by various other conditions including heart disease and is most common in those over 65. Depending on where the heart muscle damage is worse, heart failure can affect mainly the right side of the heart or mainly the left side.心力衰竭是所造成的其他各种条件，包括心脏病和最常见的是在那些超过65岁。取决于在何处的心脏肌肉损伤更糟的是，心脏衰竭，可影响，主要是右侧的心脏，或主要的左边。
- Right heart failure occurs if blood returning from the body to the right side of the heart cannot be pushed on to the lungs quickly enough.右心衰竭发生，如果回流的血液从身体右侧的心脏，不能推就向肺部不够快。
- Left heart failure occurs when the left side of the heart is unable to clear the blood from the lungs quickly enough, causing breathlessness and fluid accumulation in the lungs.左心衰竭发生时，左侧的心脏，是无法以清除血液从肺部不够快，造成呼吸急促和流体的积累在肺部。
Right heart failure is most commonly a secondary effect of left heart failure.右心衰竭是最常见的次要作用的左心衰竭。 It is rare for either side to fail in complete isolation.这是难得的任何一方要失败的完全孤立。 Left heart failure is the more common of the two.Heart failure can either be acute (it can come on quickly, without warning) or chronic (a long standing problem).左心衰竭是较常见的的two.heart失败，可以是急性（它可以来很快就在没有警告的）或慢性（长期问题） 。
