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.

重要的差别是不稳定型心绞痛心脏组织是活的，但缺/缺氧；而心肌梗死意味着该区域心组织已发生坏死。

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.

这种炎症会增加心肌梗死的发病风险，即平时所说的“心脏病发作”，同时中风、周围管疾病的发病风险也会增加，其中周围管疾病的常见表现是下肢剧烈疼痛。

The posterior cerebral artery can also be compressed, which results in ischemic stroke of the occipital part of the brain, which is responsible for processing of visual information.

另外，大脑后动脉也会受到压迫，导致大脑枕部缺性脑梗死；大脑枕部区域本来负责视觉信息的处理。

Ischemic and infarcted tissue results in the sloughing off of intestinal mucosal tissue, blood, and mucus into the gut.

缺及梗死使肠粘膜组织脱落，与液、粘液一同进入肠道。

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

心肌梗死导致心肌细胞死亡，引发累及浆膜心包的强烈炎症反应。

The displaced part of the brain can compress the anterior cerebral artery, and that can cause an ischemic stroke.

大脑移位的部分会压迫大脑前动脉，可导致缺性脑梗死。

Some causes of cerebral edema are an large ischemic strokes and meningitis.

脑水肿可能的原因还包括严重脑梗死、脑膜炎。

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，流会被断，引起心肌梗死，即心肌的部分坏死。

This typically happens when atrial cells get irritated and stressed - the causes of that might include electrolyte imbalances, drugs like cocaine or methamphetamines, ischemic damage like a heart attack, or anything that increases sympathetic activity, like anxiety.

这通常发生于心房细胞受到激惹和应激时，原因可能包括电解质紊乱、使用可卡因或麻黄碱类药物、心肌梗死等缺性损伤，或焦虑等增高交感神经活性的因素。

And infratentorial herniations can compress the vital area in the brain stem that controls consciousness, respiration, and heart rate.

幕上脑疝可能压迫脑的供养动脉，造成脑缺梗死；枕骨大孔疝可能压迫脑干的生命中枢，即控制意识、呼吸和心率的部位。

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

急性心包炎通常原因未明，也可因病毒感染或心肌梗死导致。

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，管就会出现小裂隙和管壁的撕裂，导致很严重的后果，像是心肌梗死、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.

不稳定型心绞痛，和稳定型心绞痛病因一样，因心内膜下层缺，应按急症救治，因为患高发心肌梗死或心脏病。

This is a myocardial infarction, or heart attack.

这是心肌梗死，也就是心脏病发作。

He said, if you are vegan, you will never, and he said this on record, there will never be heart disease or heart attack in your future, ever.

他说，如果你是素食主义，你就永远不会，他明确表示过，你将来绝对不会得心脏病或心肌梗死。

If those placements are significant and not just coincidence, perhaps a heart disease or heart attack was the cause of death.

如果这些位置很重要而不仅仅是巧合，或许心脏病或心肌梗死是导致死亡的原因。

In contrast partial occlusion may progress to localized infarction.

相反，部分闭塞可发展为局部梗死。

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

你的心跳加速，或我们称之为心律不齐，以及其他心脏症状可能表现为心肌梗死。

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，心肌细胞损伤不是永久性的，即可逆，心肌细胞不会死亡；这也是与心肌梗死的区别。

Well, he looked at his EKG and he said, Oh, this is a right side heart attack.

他看了看心电图，说，哦，这是右心侧的心肌梗死。
