Effects of Congestive Heart Failure 充血性心力衰竭的影响
单词单词 ventricular/ven'trɪkjʊlə/adj.心室的，膨胀的 Ventricle/ˈventrɪkl/n.心室 stiff/stɪf/可做名词，动词，形容词，副词，本文中译为僵硬的 edema/I'di:mə/n.水肿（补充：edematous(e-dem'ă-tŭs)adj.[医]水肿性，短语如：edematous pyloricobstruction 水肿性幽门梗阻，近义词oedematous/'i:demətəs/adj.水肿的）
短语学习 heart failure/hɑ:t ˈfeiljə/[医]心力衰竭 out of breath/aut ɔv breθ/呼吸急促(补充：in the same breath/in one breath 相提并论；waste one's breath 徒费口舌) stress hormones应激激素（补充：高等动物的应激激素主要有：促肾上腺皮质激素、糖皮质激素、血管紧张素等。） To make up for/tu:meikʌpfɔ:/补偿（make up 与make up for 的区别：make up for 表示“弥补；补足”，主要指通过提供一些好的东西来平衡或弥补不好的情况或影响。make up for 表示“弥补；补足”，主要指通过提供一些好的东西来平衡或弥补不好的情况或影响。）
语句学习 If you have heart failure, your heart has lost the ability to pump enough blood to meet your body's needs. 如果患有心力衰竭，患者的心脏将无法泵出足够的血液以满足身体的需求。
You're failing left ventricle also increases the blood pressure in the blood vessels between your 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 breathe. 左心衰竭也会增加双肺和左心室之间血管的血压，迫使血液进入肺组织，引起呼吸困难。
To make up for the decreased amount of blood, your nervous system releases stress hormones that increase the speed and force of your heartbeat. 为补偿减少的血量，神经系统会释放应激激素，增加心跳速度和力度。

If you have heart failure, your heart has lost the ability to pump enough blood to meet your body's needs. You may have weak or damaged ventricular walls that are not able to push enough blood out of your heart. You may also have stiff and thickened ventricular walls that do not allow your heart to fill with enough blood. 如果患有心力衰竭，患者的心脏将无法泵出足够的血液以满足身体的需求。患者的心室壁可能无力或受损，这样就无法将足够的血液泵出心脏。此外，心室壁也可能会僵硬和增厚，从而使心脏血液充盈受限。
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. You're failing left ventricle also increases the blood pressure in the blood vessels between your 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 breathe. 如果患有左心衰，患者左心室便无法将足够多富含氧气的血液输送至全身，患者会感到疲倦，呼吸急促。左心衰竭也会增加双肺和左心室之间血管的血压，迫使血液进入肺组织，引起呼吸困难。
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 a buildup of blood in your veins, which causes a buildup of fluid, called edema, throughout the tissues in your body. Over time, heart failure on either side of your heart results in weakened and enlarged ventricles that deliver less blood to your body. 如果患有右心衰，患者右心室将收缩无力，无法将血液推入双肺，从而引起全身组织水肿。随着时间的推移，任一侧心衰均导致心室无力，肥厚，从而使输送至身体的血量减少。
To make up for the decreased amount of blood, your nervous system releases stress hormones that increase the speed and force of your heartbeat. Unfortunately, the continued release of these stress hormones makes your heart failure worse because they damage the muscle cells in your ventricles. 为弥补减少的血量，神经系统会释放应激激素，增加心跳速度和力度。遗憾的是，持续释放应激激素会使心衰恶化，因为它们会损害心室肌细胞。
