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

急炎通常持续数周时间，而炎持续时间较长，大于6个月。

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

炎症持续数周甚至数月时，称炎。

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

炎是指脏表层膜发生的炎症反应。

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炎，即的炎症。

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

试验中也没有肌炎或炎的案例，这两种疾分别是脏肌肉或脏外膜发炎。

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

诊断炎和积液的方法如下。

Other causes of pericarditis include cancer, radiation therapy in the chest, and even medications like penicillin, and certain anticonvulsants.

其他因括癌症、胸部放疗，甚至药物，如青霉素和一些抗惊厥药。

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

所以这可能来自合或炎或类似的东西。

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

急炎通常是特发的；特发指原因不明。

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炎。你对那个有了解吗？

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.

另一个因是尿毒症炎，由肾脏疾引发尿素（血浆含氮代谢产物）水平升高导致。

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

炎源于纤维蛋白在浆膜沉积，影响肌的舒张充盈功能。

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

炎的主要症状是发热，以及随深呼吸加重、随坐直和前倾减轻的胸痛。

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.

炎患者也有罹患积液的风险，即炎症反应使液体聚集在脏周围。

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

急炎通常原因未明，也可因毒感染或肌梗死导致。

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.

当转移到时，通常会导致炎，即被感染引起的炎症，并引起积液，即在腔内积聚液体。

On an echocardiogram, a pericardial effusion makes the heart look like it's dancing within the pericardium, whereas chronic pericarditis shows the stiff serous pericardium restricting the heart's movement.

超声动图下，积液致使脏如同在腔内“舞蹈”；而炎表现增厚的限制脏活动。

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.

在炎中，免疫细胞募集成纤维细胞分泌大量纤维蛋白，使浆膜硬化，与纤维质相似。

And there were no cases of myocarditis or pericarditis—inflammation of the heart muscle or lining—which have occurred in a small percentage of teens and young adults who got the Pfizer or Moderna vaccines.

而该年龄段未出现肌炎或炎现象——脏肌肉或内膜炎症——而少部分接种了辉瑞或莫德纳疫苗的青少年和青年后会产生。

When you get all this inflammatory sort of stuff happening on just beneath the pericardiumon the outside of the heart, you could irritate your pericardium and you could end up with a condition called pericarditis.

下的脏外发生炎症时，可能刺激，最后可能引起炎。
