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。

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。

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。

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痛，而不稳定型心绞痛和血管痉挛型心绞痛可随时发生，包括休息时。

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

即使在它成为心绞痛（痛的技术术语）的公认治疗方法之后。

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是心内膜下层缺血，即到达心内膜下层的氧减少。

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

如果血液水平保持正常，则稳定型心绞痛会出现完全缺血。

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

如，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。

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，就会引起疼痛，我们称之为心绞痛。

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。

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

第三种心绞痛是血管痉挛型心绞痛（变异型心绞痛），患者可能有或无动脉粥样硬化。

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

不稳定型心绞痛和非ST段抬高型心肌梗死被归为非ST段抬高型急性冠脉综合征。

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

相反，血管痉挛型心绞痛因透壁性缺血显示ST段抬高。

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。

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

此外，血管痉挛型心绞痛对钙离子通道抑制剂敏感。

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。

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。

The mechanism generating ST depression and T-wave inversion in patients with unstable angina and non ST elevation MI are poorly understood.

不稳定型心绞痛和非ST段抬高型心肌梗死患者ST段压低和T波倒置的机制尚不清楚。

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。

In the majority of cases, the underlying cause of stable angina is atherosclerosis of one or more the coronary arteries—arteries supplying blood to the heart muscles.

大多数情况下，稳定型心绞痛的根本原因是一至多个冠状动脉（供应心肌的动脉）发生粥样硬化。
