Acute pericarditis generally lasts just a few weeks, whereas chronic pericarditis lasts longer, usually more than 6 months.

急性心包炎通数周时间，而慢性心包炎时间较长，大于6个月。

So pericarditis means the pericardial layer of tissue that covers the heart has inflammation.

心包炎是指心脏表层心包膜发生的炎症反应。

The buildup of toxins can also cause pericarditis which is inflammation of the lining of the heart.

毒素的累积也会引起心包炎，即心包的炎症。

When the inflammation persists for weeks to months, the process is called chronic pericarditis.

炎症数周甚至数月时，称为慢性心包炎。

Post-hepatic causes include right-sided Heart failure, Constrictive Pericarditis and Budd-Chiari syndrome.

肝后型病因包括右心衰、缩窄性心包炎、巴德-吉亚利综合征（布加综合征）。

Myocarditis can also be caused by infections, including COVID itself, where it is often more severe.

心包炎也可由包括感染引起，其中包括新冠病毒，而它引发的症状通更严重。

There were also no cases of myocarditis or pericarditis — inflammation of the heart muscle or its lining.

试验中也没有心肌炎或心包炎的案例，这两种疾病分别是心脏肌肉或心脏外膜发炎。

There are a few ways to diagnose pericarditis and pericardial effusions.

诊断心包炎和心包积液的方法如下。

So this could be from like a pericardial fusion or pericarditis or something like that.

所这可能来自心包融合或心包炎或类似的东西。

When the cause is identified, it's usually a viral infection, like Coxsackie B virus.

急性心包炎的已知病因通是病毒感染，如柯萨奇B组病毒。

Now, the cause of acute pericarditis is usually idiopathic, meaning that we don't know what causes it.

急性心包炎通是特发性的；特发性指原因不明。

Oh, yes, he'll...he'll live, but, uh, the doctor says he's at risk for something called pericarditis. Do you know anything about that?

是的，他--他会活下来，但是，嗯，医生说他有可能会有心包炎。你对那个有了解吗？

Chronic pericarditis typically results from fibrin deposition in the serous pericardium and it prevents the heart from fully relaxing.

慢性心包炎源于纤维蛋白在浆膜心包沉积，影响心肌的舒张充盈功能。

The main symptom of pericarditis is fever and chest pain that worsens with deep breathing, but improves with sitting up and leaning forward.

心包炎的主要症状是发热，及随深呼吸加重、随坐直和前倾减轻的胸痛。

Another cause of pericarditis, called uremic pericarditis, is when blood levels of urea, a nitrogen waste product, get really high usually due to kidney problems.

另一个病因是尿毒症性心包炎，由肾脏疾病引发尿素（血浆含氮代谢产物）水平升高导致。

People who develop pericarditis are also at risk of developing a pericardial effusion - that's when the inflammation causes fluid to accumulate around the heart.

心包炎患者也有罹患心包积液的风险，即炎症反应使液体聚集在心脏周围。

Okay, let's recap - acute pericarditis is usually caused by a idiopathic causes, but can be caused by viruses or after a myocardial infarction.

急性心包炎通原因未明，也可因病毒感染或心肌梗死导致。

Pericarditis can also be seen in autoimmune diseases, like rheumatoid arthritis, scleroderma, or systemic lupus erythematosus, because the immune system attacks its own tissues, including the pericardium.

心包炎也可继发于自身免疫病，如类风湿性关节炎、硬皮病或系统性红斑狼疮；此时免疫系统攻击包括心包在内的自身组织。

When the pericardium is involved, it often leads to pericarditis —inflammation of the pericardium— and pericardial effusion, an accumulation of fluid in the pericardial cavity.

当转移到心包时，通会导致心包炎，即心包被感染引起的炎症，并引起心包积液，即在心包腔内积聚液体。

In chronic pericarditis, immune cells start to recruit fibroblasts which create lots of fibrin - a protein that makes the serous pericardium stiffer - a bit more like the fibrous pericardium.

在慢性心包炎中，免疫细胞募集成纤维细胞分泌大量纤维蛋白，使浆膜心包硬化，与纤维心包性质相似。
