两种类型的心脏衰竭影响的左边the heart: systolic and diastolic. If you’ve been diagnosed with left-sided — also called left-ventricle — heart failure, you may want to understand more about what these terms mean.
总的来说，心力衰竭是当您的心脏不足以使您保持健康的情况下会发生一种情况。当您进行体育锻炼或感到压力时，您的心脏可能会更有效地抽水。
If you have systolic heart failure, it means your heart isn’t contracting well during heartbeats. If you have diastolic heart failure, it means your heart isn’t able to relax normally between beats. Both types of left-sided heart failure can lead to right-sided heart failure.
When it comes to diagnosing and managing these two types of heart failure, there are some similarities and some differences. Read on to find out what you need to know about systolic and diastolic heart failure.
Systolic heart failure happens when the left ventricle of your heart can’t contract completely. That means your heart won’t pump forcefully enough to move your blood throughout your body in an efficient way.
它也称为心力衰竭，减少了射血分数（HFREF）。
Ejection fraction (EF) is a measurement of how much blood leaves a heart ventricle every time it pumps. The more the heart pumps out, the healthier it is.
Doctors will tell you your EF as a percentage after doing an imaging test, such as an echocardiogram. Between
If you have an EF of under
当您的左心室无法在心跳之间放松时，会发生舒张期心力衰竭，因为组织变得僵硬。当您的心脏无法完全放松时，下一次节奏之前就不会再充满血液。
这种类型也称为心力衰竭，保留了射血分数（HFPEF）。在这种类型中，您的医生可能会对您的心脏进行成像测试，并确定您的EF看起来不错。然后，您的医生会考虑您是否有其他心力衰竭症状，以及是否有证据表明您的心脏无法正常运作。如果满足这些标准，您可能会被诊断出患有舒张期心力衰竭。
This type of heart failure most often affects older women. It often occurs alongside other types of heart disease and other non-heart conditions such as cancer and lung disease.
There are many medications available to treat systolic heart failure. These include:
- 血管紧张素转换酶(ACE)抑制剂
- angiotensin receptor-neprilysin (ARN) inhibitors
- angiotensin receptor blockers (ARBs)
- β受体阻滞剂（BBS）
- digoxin
- 利尿剂
- F-channel blockers
- 肌力
- mineralocorticoid receptor antagonists (MRAs)
For some people, a combination of these treatments can be effective.
例如，一种将Sacubitril，ARN抑制剂和ARB Valsartan结合在一起的药物被指定为“

医生可以使用许多相同的药物治疗舒张期心力衰竭，这些药物是收缩性心力衰竭的选择。但是，这种类型的心力衰竭尚未得到充分理解或研究。这意味着医生对最有效的治疗方法没有相同的准则。
通常，用药物治疗舒张性心力衰竭的主要方法包括：
- Medications to relax or widen blood vessels.These may include ARBs, BBs, calcium channel blockers, or long-acting nitrates. It could also include vasodilators, such as nitroglycerin.
- 减少液体积聚的药物。Diuretics, sometimes called “fluid pills,” help your body get rid of excess fluid.
- 控制其他疾病的药物。Treatment may focus on managing conditions such as high blood pressure, which can have a big effect on diastolic heart failure.
Implanted devices
对于某些患有左侧心力衰竭的人来说，一种手术植入的装置可改善心脏功能。设备的类型包括：
- 可植入的心脏逆转除颤器（ICD）。If you have heart failure and irregular heartbeats, this gives your heart a shock when your heartbeat is not regular. This helps your heart beat properly again.
- 心脏重新同步疗法（CRT）。这是一个特殊的起搏器，有助于您心脏的心室，使它们正常和正确的节奏合同。
- 左心室辅助装置（LVAD）。This pump-like device is often called a “bridge to transplant.” It helps the left ventricle do its job when it’s no longer working well, and it can help you while you wait to get a heart transplant.
手术
在某些情况下，建议手术治疗左侧心力衰竭。手术有两种主要类型：
- Corrective surgery.如果您的心脏出现身体问题会导致心力衰竭或使其恶化，则可能会接受手术来解决它。例子包括冠状动脉旁路，可在动脉阻塞周围重新穿血液和瓣膜置换手术，该手术纠正了无法正常工作的瓣膜。
- Transplant.If heart failure progresses to a very serious state, you might need a new heart from a donor. After this surgery, you’ll have to take medication so your body doesn’t reject the new heart.
If you’ve been diagnosed with heart failure, talk to your doctor about what type of heart failure you have. Understanding the type of heart failure may help you understand your treatment options better. Sticking to your treatment plan and taking your medication as prescribed are the best ways to manage the condition and reduce your risk of complications.
