医学英语术语的学习从基础学起，如果您还在迷茫，建议阅读小编原创的入门教程。啊，我连最基本的词汇构成都不知道啊，点击这里。如果您一直在寻找较好的词典，可点击这里。很多时候，总是看了又忘，忘了再看，有什么好办法逆转这个呢？点击这里。啊，怎么我总是忘了一些基本的词根词缀，那你就应该点击这里。  Your heart is a muscular organ that pump blood containing the oxygen and nutrients you body needs. 心脏是由心肌构成的动力器官,它能泵出富含氧气和营养物质的血液供给全身需要。
The pumping section of the heart are： right artium， right ventricle，left artium and left ventricle. 心脏有四个腔室：右心房、右心室、左心房、左心室。 In your heart oxygen-poor blood flows from you body through large veins to right artium，next the blood moves into your right ventricle，which contracts sending blood out of your heart to pick up oxygen from your lung. 含氧量低的静脉血从大静脉流入右心房，再进入右心室。右心室收缩，将心脏中的血液输送到肺部变成含氧丰富的动脉血。 Oxygen-rich blood moves out of your lung into your left artium.And moves into left ventricle.Finally your left ventricle contracts，sending oxygen-rich blood out of your heart to your body 动脉血从肺部流出进入左心房,再进入左心室,最后你的左心室收缩，将含氧血输送到身体各处。
If you have heart failure，your heart lost the ability to pump enough blood to meet you body’s need. 如果发生心力衰竭，心脏无力将足够血液泵出，无法满足身体需求。 You may have weak or damaged left ventricular walls that are not able to push enough blood out of your heart. 左心室壁力量衰减或肌肉受损，会导致心脏泵血不足。 You may also have stiff ventricular walls that do not allow your heart to fill with enough blood 心室壁僵硬会导致心脏充血不足。 If you have left-sided heart failure，your left ventricle does not deliver enough oxygen-rich blood to your body，making you feel tired and out of breath. 如果是左心衰竭，左心室无法将含氧血输出到身体各处。你会感到疲劳、气短。 Your failing left ventricle also increases blood pressure in the blood vessel between lungs and left ventricle. This increased pressure forces fluid out of your blood and into your lung tissues，which makes it difficult for you to breath 肺部和左心室之间的血压也会因此升高。血液中的液体受压力作用进入肺部细胞，出现呼吸困难的症状。 If you have right-sided heart failure，your right ventricle is unable to contract with enough force to push blood to your lungs. The result is built up of blood in your veins，which causes the build up of a fluid called edema throughout the tissue in your body 如果是右心衰竭，右心室收缩力量不足，无法将血液输送到肺部，会造成血液淤积，导致全身组织水肿。
Over time heart failure on either side of your heart，results in weakened and larged ventricles that deliver less blood to your body. 不论心衰发生在哪一边，久而久之都会导致心脏扩大、心室衰竭、供血减少。 To make up for the decreased amount of blood，your nerve system release stress hormones that increase the speed and force of your heart beat. 为了补偿减少的血量，神经系统会释放应激激素,增加心跳速度和强度。 Unfortunately，the continue release of the stress hormones make your heart failure worse，because they damage the muscle cells in your ventricles 但是应激激素的持续分泌会加剧心力衰竭，因为它们会损伤心室的心肌细胞。 The most common cause of heart failure is coronary artery disease. 心力衰竭最常见的病因是冠心病。 Other causes of heart failure: 其他病因包括：
Treament for heart failure includes： 心力衰竭的治疗方法包括：
In extreme heart failure： 在严重心力衰竭的治疗方法包括：
Diuretic medications reduce swelling in your body by increasing the amout of urine produced by your kidneys 利尿剂可增加肾脏排尿量，缓解身体肿胀。
ACE inhibitors are medications that allow your blood vessels to expand，this helps to decease blood pressure. And prevents further damage to your heart to pump blood by making it easier for the heart to pump blood 血管紧张素转换酶抑制剂可促进血管扩张,是有效的降压药物，它能改善心脏泵血状况，防止心肌进一步损伤。
Beta blocker β阻滞剂 Beta blockers Beta blockers are medications that block the effects of stress hormones on you heart. Although beta blockers slow down your heart beat Β阻滞剂有助于降低应激激素对心脏的影响，但是Β阻滞剂会减缓心跳。
They are mainly used to protect your heart muscles from long term damage caused from stress hormones 以上是保护心脏免受应激激素长期影响的常用药物。
You may need to make some lifestyle changes，including：
Surgery for advanced heart failure include： 晚期心力衰竭患者的手术包括:
To improve your heart muscle 增强心肌活性
To improve blood flow through your heart 提高心脏血流量
To remove damaged heart muscle 切除受损心肌细胞 Surgery for extreme heart failure include： 对于严重心衰的患者，手术包括:
Incision of a device to help your heart pump blood 心脏中内置辅助泵血装置
