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，称为慢性心包炎。

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

急性心包炎通常持续数周时间，而慢性心包炎持续时间较长，大于6个月。

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。

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.

超声心动图下，心包积液致使心脏如同在心包腔内“舞蹈”；而慢性心包炎表现为增厚的心包限制心脏活动。

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。
