Heart failure is caused by diseases or other factors that affect the pumping ability of the heart, specifically the left lower chamber (left ventricle).心力衰竭是由于疾病或其他因素影响抽水能力的核心，尤其是在左下室（左心室） 。 When the heart cannot pump well, it is called systolic heart failure.当心脏不能泵顺利，它被称为收缩期心脏衰竭。 Things that affect how the heart pumps include:事情如何影响心脏泵包括： - Coronary artery disease (CAD) and heart attack (most common causes).冠状动脉疾病（ CAD ）和心脏病发作（最常见的原因） 。
- Damage from poorly controlled high blood pressure or diabetes.不善造成的损害控制血压高或糖尿病。
- Cardiomyopathy, alcoholic cardiomyopathy, or infection or inflammation of the heart muscle (such as myocarditis).心肌病，酒精性心肌病，或感染或炎症的心脏肌肉（如心肌炎） 。
- Illegal drugs (such as a stimulant, like cocaine).非法药物（如兴奋剂，如可卡因） 。
- Disease of the sac surrounding the heart (pericardial disease).病囊周围的心（心包疾病） 。
- Heart disease that is present from birth (congenital heart disease).心脏疾病，这种疾病是目前从出生（先天性心脏病） 。
- Heart valve disease.心脏瓣膜疾病。
- Fast, slow, or irregular heart rhythms (arrhythmias).快，慢，或不规则的心脏节律（心律失常） 。
- Aging.老化。 As you age, your heart muscle tends to stiffen, which can prevent your heart from filling properly with blood.如你的年龄，您的心脏肌肉会变硬，它可以防止你的心从填写正确带有血迹。
- A rare kind of heart failure called postpartum heart failure.一种罕见的心脏衰竭称为产后心力衰竭。 This can happen late in the pregnancy or within the first 5 months after delivery.这种情况可能在年底或在怀孕的前5个月后交付。
When the left ventricle cannot fill properly, it is called diastolic heart failure.当左心室不能填写正确，这是所谓的舒张性心力衰竭。 High blood pressure, coronary artery disease, and heart valve problems can cause diastolic heart failure.血压高，冠心病，心脏瓣膜和问题可能会导致舒张性心力衰竭。 Specific triggers may suddenly make heart failure worse and may sometimes cause life-threatening conditions such as pulmonary edema or cardiogenic shock.具体触发可能突然使心脏衰竭恶化，有时可能会导致危及生命的条件，如肺水肿或心源性休克。 More information 更多信息 - What causes systolic heart failure?起因是什么脉动心脏衰竭？
