And that can lead to a myocardial infarction, which is what we also call a heart attack.

这可能导致梗塞，也就是我们所说的脏病发作。

One study published over the summer in JAMA Cardiology, for example, found that of a sample group of 100 people who had recovered from COVID-19, 78 had some inflammation of myocardial tissue or other damage such as scarring.

例如，今年夏天发表在《美国医学会脏病学杂志》上的一项研究发现，在100名新冠患者中，有78人出现组织炎症或疤痕等其他损伤。

The inflammation increases the risk of having a myocardial infarction - a heart attack, as well as a stroke, and peripheral vascular disease which is where there is severe pain in the lower legs.

这种炎症会增加梗死的发病风险，所说的“脏病发作”，同中风、周围血管疾病的发病风险也会增加，其中周围血管疾病的最常见表现是下肢剧烈疼痛。

As a result of ischemia, in the myocardium supplied by coronary artery B, the myocardial cells don't receive enough oxygen, which is called hypoxia.

于是冠脉B供血的出现了缺血，细胞无法获得足够的氧气，称为“缺氧”。

In particular, it's implicated in oxidative stress and myocardial fibrosis — an abnormal thickening of the heart valves.

醛固酮与氧化应激和化（脏瓣膜异常增厚）尤其相关。

The key distinction is that unstable angina means that the heart tissue is alive but ischemic or starving for oxygen, whereas myocardial infarction means that the areas of heart tissue have already begun to necrose or die.

两者最重要的差别是不稳定型绞痛脏组织是活的，但缺血/缺氧；而梗死意味着该区域组织已发生坏死。

Basically, when heart cells die in a myocardial infarction, it leads to massive inflammation that also involves the serous pericardium.

梗死导致细胞死亡，引发累及浆膜包的强烈炎症反应。

In severe cases, blood flow can been completely cut off, which results in myocardial infarction, or the necrosis of a portion of myocardium.

严重的情况下，血流会被完全阻断，引起梗死，的部分坏死。

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

急性包炎通常原因未明，也可因病毒感染或梗死导致。

Just like a garden hose that's always under high pressure, in the long term, blood vessels can develop tiny cracks and tears that can lead to serious problems, like myocardial infarctions, aneurysms, and strokes.

就像是花园里面浇水的水管，如果总处于高压之下，久而久之，血管就会出现小裂隙和管壁的撕裂，导致很严重的后果，像是梗死、动脉瘤和中风。

Unstable angina, for the same reason as stable angina, involves subendocardial ischemia and it should be treated as an emergency, because patients are at a high risk of progressing to myocardial infarction, or heart attack.

不稳定型绞痛，和稳定型绞痛病因一样，因内膜下层缺血，应按急症救治，因为患者高发梗死或脏病。

This is a myocardial infarction, or heart attack.

这是梗死，也就是脏病发作。

An MI means myocardial infarction, just another name for a heart attack.

MI 表示梗塞，只是脏病发作的别称。

The primary outcome was a composite outcome of acute kidney injury, acute myocardial injury, nonfatal cardiac arrest, or death within the first seven postoperative days.

主要终点为术后7天内发生的急性肾损伤、急性损伤、非致命性脏骤停或死亡的复合终点。

Your heart is racing or what we call arrhythmias and other cardiac symptoms can present as myocardial infarctions.

你的跳加速，或者我们称之为律不齐，以及其他脏症状可能表现为梗死。

Symptoms of coronary steal syndrome mimic that of a myocardial infarction, and include a typical type chest pain, which is described as a squeezing pain or pressure that might radiate up to the left arm, jaw, shoulders, or back.

冠状动脉窃血综合征的症状和梗类似，包括典型的胸痛，被描述为“压榨性”疼痛或有“紧迫感”，可能辐射到左臂、下颌、肩和背部。

It should be noted, however, that this condition is clinically unstable and often precedes a myocardial infarction.

钙蛋白水保持正常，或只是轻微升高。然而，应该指出的是，这种疾病在临床上是不稳定的，而且常常发生在梗死之前。

So we've seen that in ST elevation MI, untreated a complete arterial occlusion may progress to infarction of the full thickness of the affected myocardial wall.

所以我们已经看到，在ST段抬高型梗死中，未经治疗的完全性动脉闭塞可能发展为壁全厚度梗死。

And it's thought that radiation generates reactive oxygen species in the tissue, which ultimately leads to inflammation over time, and causes myocardial fibrosis, or fibrosis of the heart muscle tissue, which makes the tissue stiffer and more restrictive.

它被认为是因为辐射会在组织中产生很多活性氧物质，随着间推移最终导致炎症，导致化，或者说脏肉组织的化，导致组织更加僵硬、受限。

First, it's super important to remember that in each case, the injury to cardiomyocytes isn't permanent, meaning it's reversible and the cardiomyocytes don't die (which is how this differs from myocardial infarction).

首先，务必记住每种情况下，细胞损伤不是永久性的，可逆，细胞不会死亡；这也是与梗死的区别。
