It also explained why nitroglycerine, the well-known explosive, soothes the heart pain known as angina.

这也解释了为什么硝酸甘油，即人们所熟知的炸药，能够缓解心绞痛。

We had a run of angina attacks, so we had to go heart-healthy.

好几个人心绞痛连续发作，所以我们不得不重视心脏健康。

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.

两者最重要的差别不稳定型心绞痛心脏组织活的，但缺血/缺氧；而心肌梗死意味着该区域心组织已发生坏死。

Even after it became an accepted treatment for angina, the technical term for chest pain, what exactly nitroglycerine does to the circulatory system remained a mystery for a long time.

即使在它成为心绞痛（胸痛的技术术语）的公认治疗方法之后。硝酸甘油究竟对循环有什么作用，长期以来一直个谜。

If you’ve got a pre-existing condition -- diabetes or cancer or heartburn or a heart attack -- you can no longer be charged more or denied coverage.

你有既往病史，例糖尿病、癌症、心绞痛、心力衰竭等等，你缴纳的保费也不会上涨，更不会被拒保。

Well, you won't remember this, but one night, two years ago, you drove me to the hospital after I had an attack of angina. Probably saved my life.

你肯定不记得了，在两年前的某一夜，我心绞痛突发，你开车送我去医院的。可以说救了我一命。

They could be that they have angina that comes and goes so it feels like there's a little bit but it goes away.

他们可能有心绞痛，来来去去，所以感觉有一点，但它会消失。

For example, drops in oxygen levels can trigger anginal chest pain, and can irritate heart cells leading to an arrhythmia—an irregular heartbeat.

比，缺氧会引起心绞痛，还会刺激心肌细胞，导致心率不齐，即不规律的心脏跳动。

It is given to people with angina, and also to those who have had heart attacks.

欣维宁针对心绞痛患者以及心脏病患者。

On an electrocardiogram, or ECG, both stable and unstable angina show an ST-segment depression since ischemia's limited to the subendocardium.

心电图上，稳定型和非稳定型心绞痛都显示ST段降低，因为缺血局限于心内膜下层。

Other heart conditions that might lead to stable angina are ones that cause a thickened heart muscle wall, which would require more oxygen.

其余可能造成稳定型心绞痛的心脏问题有心肌肥厚等：肥厚的心肌需要更多氧气。

Unstable angina is usually caused by rupture of atherosclerotic plaque with thrombosis, meaning a blood clot forms on top of a mound of plaque.

不稳定型心绞痛通常由于动脉粥样硬化伴血栓破裂，即血栓在斑块表面形成。

Therefore the classic finding with angina is subendocardial ischemia, meaning less oxygen is reaching the region just under the endocardium.

因此心绞痛的典型发现就心内膜下层缺血，即到达心内膜下层的氧减少。

Alright, so if we line these three up side-to-side, there's some important clinical similarities and differences.

好的，我们对比这3种类型的心绞痛，就会发现一些重要的临床相似点和不同点。

In terms of medications, all three can be treated with Nitroglycerin which is a vasodilator that increases blood vessel diameter to allow more blood flow.

用药方面，3种心绞痛都可以用硝酸甘油治疗；硝酸甘油扩血管物质，增加血管直径，使更多血流通过。

Even after it became an accepted treatment for angina, the technical term for chest pain.

即使在它成为心绞痛的公认治疗方法之后，心绞痛胸痛的专业术语。

For example, if you are a chronic worrier, you may be stricken some day with one of the most excruciating pains ever endured by man: angina pectoris.

例，您长期忧虑，某天您可能会遭受人类有史以来最难以忍受的痛苦之一：心绞痛。

Now a third type of angina is vasospastic angina, also known as Prinzmetal angina, and patients may or may not also have atherosclerosis.

第三种心绞痛血管痉挛型心绞痛（变异型心绞痛），患者可能有或无动脉粥样硬化。

He lost it when our Aunt Rose had angina.

当我们的罗斯姨妈患心绞痛时，他失去了它。

All patients with suspected ACS are treated promptly with antiplatelets (usually aspirin), angina medications (usually nitroglycerin) and supplemental oxygen if required.

所有疑似急性冠脉综合征的患者都会立即接受抗血小板（通常阿司匹林）、心绞痛药物（通常硝化甘油）和补充氧气（需要）。
