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。

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

好几个人心绞发作，所以我们不得不重视心脏健康。

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

欣维宁针对心绞患者以及心脏病患者。

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

好的，如果我们对比这3种类型的心绞，就会发现一些重要的临床相似点和不同点。

In contrast, vasospastic angina shows ST-segment elevation due to transmural ischemia.

相反，血管痉挛型心绞因透壁性血显示ST抬高。

In addition, vasospastic angina also responds to calcium channel blockers.

此外，血管痉挛型心绞对钙离子通道抑制剂敏感。

Rest tends to relieve stable angina, whereas unstable angina and vasospastic angina can occur anytime, including at rest.

休息可缓解稳定型心绞，而不稳定型心绞和血管痉挛型心绞可随时发生，包括休息时。

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都显示ST，因为血局限于心内膜下层。

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

即使在它成为心绞（胸的技术术语）的公认治疗方法之后。

He lost it when our Aunt Rose had angina.

当我们的罗斯姨妈患心绞时，他失去了它。

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

比如，氧会引起心绞，还会刺激心肌细胞，导致心率不齐，即不规律的心脏跳动。

Invented tools and techniques help us ward off diseases, from angina pectoris to more common chest concerns.

发明的工具和技术帮助我们抵御疾病, 从心绞到更常见的胸部问题。

If the blood flow through the coronary arteries is blocked, it can cause pain, and we call that angina.

如果通过冠状动脉的血流受阻，就会引起疼，我们称之为心绞。

If the blood levels remain normal, they have pure ischemia on stable angina.

如果血液水平保持正常，则稳定型心绞会出现完全血。

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，来来去去，所以感觉有一点，但它会消失。

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

第三种心绞是血管痉挛型心绞（变异型心绞），患者可能有或无动脉粥样硬化。

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.

因此心绞的典型发现就是心内膜下层血，即到达心内膜下层的氧减少。

These larger, thicker heart muscles require more oxygen, and if the patients can't meet increasing demands, they feel pain in the form of angina.

这些肥厚的心肌需要更多氧气，如果患者不能够满足心肌日益增长的需要，便出现心绞。

Unstable angina and non ST elevation MI are grouped together under the general term non-ST elevation acute coronary syndromes.

不稳定型心绞和非ST抬高型心肌梗死被归为非ST抬高型急性冠脉综合征。
