原声例句
Osmosis-心血管 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。 Osmosis-心血管 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。 Osmosis-心血管 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。 医学英语 心内科 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。 医学英语 心内科 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。 Osmosis-心血管 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，因心内膜下层缺血，应按急症救治，因为患者高发心肌梗死或心脏病。 Osmosis-心血管 Unlike both stable and unstable angina, in this case the coronary artery's constricted so severely that all layers of the heart wall being supplied are affected, therefore it's referred to as transmural ischemia. 与稳定型、非稳定型不同，这种情况下冠状动脉极度收缩，心壁所有层都受影响，因此，也被称为透壁性缺血。 医学英语 心内科 If such an episode of partial occlusion resolves with no infract developing in the ischemic area, the patient is said to have suffered an episode of unstable angina. 如果这种局部闭塞的发作得到解决，而缺血区没有出现任何不良反应，则患者被称为患有不稳定型心绞痛发作。 Osmosis-心血管 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心绞痛心脏组织是活的，但缺血/缺氧；而心肌梗死意味着该区域心组织已发生坏死。 医学英语 心内科 Depending on the location and the extent of obstruction, one of the following conditions may result: - Unstable angina, - Non-ST-segment elevation myocardial infarction, NSTEMI, - Or ST-segment elevation myocardial infarction, STEMI. 根据梗阻的位置和程度，可能会出现以下情况之一：-不稳定型心绞痛，-非ST段抬高性心肌梗死，-或ST段抬高性心肌梗死。
英语百科
Unstable anginaUnstable angina (UA) is a type of angina pectoris that is irregular. It is also classified as a type of acute coronary syndrome (ACS). It can be difficult to distinguish unstable angina from non–Q-wave myocardial infarction. Unstable angina (UA) and non-ST elevation (non-Q wave) myocardial infarction (NSTEMI) differ primarily in whether the ischemia is severe enough to cause sufficient damage to the heart's muscular cells to release detectable quantities of a marker of injury (typically troponin T or troponin I). Unstable angina is considered to be present in patients with ischemic symptoms suggestive of an ACS and no elevation in troponin, with or without ECG changes indicative of ischemia (e.g., ST segment depression or transient elevation or new T wave inversion). Since an elevation in troponin may not be detectable for up to 12 hours after presentation, UA and NSTEMI are frequently indistinguishable at initial evaluation. |
