Causes of Heart failure原因心力衰竭

Heart failure can be caused by any condition that puts the heart muscle under strain or causes damage to it.心脏衰竭可造成的任何条件，这使心脏肌肉紧张或造成损害。 It is most commonly caused by a heart attack,  coronary artery disease  (narrowing of the major blood vessels to the heart) and high blood pressure.这是最常见的引起的心脏病发作，冠状动脉疾病（收窄，主要血管的心脏）及血压高的压力。 Other causes include:其他原因包括：

  • Leaking heart valves, with blood regurgitation (flowing backwards through the system);漏水，心脏瓣膜，血液逆流（向后流动，通过制度） ;
  • Narrowing of heart valves, putting increased strain on heart muscles;缩小的心脏瓣膜，把增加应变对心脏的肌肉;
  • Chronic lung disease such as COPD (chronic obstructive pulmonary disease), causing increased resistance to blood flow through the lungs;慢性肺疾病，如慢性阻塞性肺疾病（慢性阻塞性肺疾病） ，导致阻力增加血流量，通过肺部;
  • Heart rhythm disorders (arrhythmia);心脏节律紊乱（心律失常） ;
  • Chronic heart muscle disease (cardiomyopathy);慢性心脏肌肉疾病（心肌病） ;
  • Excessive alcohol consumption;过多的酒精消费;
  • A viral infection;病毒感染;
  • Thyroid gland disease; and甲状腺疾病;
  • Anaemia.贫血。

Heart failure can be brought on in a weakened heart by additional factors that put strain on the heart.心力衰竭，可带来的在一个削弱了心脏的额外因素，提出应变对心脏。 These include pregnancy, obesity, anaemia, severe lung infections such as pneumonia, and infection of the heart lining (endocarditis).这些措施包括怀孕，肥胖，贫血，严重肺部感染，如肺炎，感染的心脏，衬砌（心内膜炎） 。

In particular, causes of acute (sudden) heart failure include:特别是，原因急性（突然）心力衰竭，包括：

  • Severe myocardial infarction (heart attack); and严重的心肌梗死（心脏病发作） ;
  • Acute infection of a heart valve (endocarditis).急性感染的一个心脏瓣膜（心内膜炎） 。 This is most likely to affect people who already have underlying heart problems such as heart valve damage or congenital heart disease.这是最有可能影响人谁已经有潜在的心脏问题，如心脏瓣膜损坏或先天性心脏病。 It can be caused by the presence of germs in the blood, for example from certain dental procedures, but people who are at risk should be given a course of antibiotics during these procedures.它可以造成在场的细菌在血液中，例如从某些牙科程序，但人谁处于危险应给予一个疗程的抗生素，在这些程序。
