诊断心脏病发作
接下来的几个小时 心脏病 会让人害怕和困惑吗. Your medical team may be busy 和 focused, 和 don’t have time to explain everything that’s happening in the moment. Your health care team is trying to identify the type of 心脏病 you’ve had 和 determine the best treatment options.
You 和 your family members are sure to have questions. You may wonder about the tests 和 procedures that are being performed.
心脏病发作的类型和诊断
A 心脏病 is also called a myocardial infarction, sometimes simply referred to as an “MI.” A 心脏病 occurs when a blockage in one or more coronary arteries reduces or stops blood flow to the heart, which starves part of the heart muscle of oxygen.
The blood vessel blockage might be complete or partial:
- A complete blockage of a coronary artery is a ST-elevation myocardial infarction (STEMI).
- A partial blockage is a non-ST-elevation myocardial infarction (NSTEMI).
Diagnostic tests 和 procedures help your medical team determine if a 心脏病 occurred, how much your heart was damaged 和 what degree of coronary artery disease (CAD) you might have. The tests help the health care team determine what treatment is needed 和 what lifestyle changes will help you improve your heart health 和 prevent future medical events.
Non-invasive diagnostic testing involving imaging may include a needle stick such as for an intravenous injection of a contrast agent. Invasive procedures can include insertion of a tube, device or scope, 和 blood tests.
Blood testing may include the following:
Cardiac enzymes (including troponin 和 creatine kinase), c反应蛋白(CRP), 纤维蛋白原, 同型半胱氨酸, 脂蛋白, 甘油三酸酯, brain natriuretic peptide (BNP) 和 prothrombin.
测试原因
- Confirms that a 心脏病 has occurred 和 determines extent of damage.
- Assesses future risk for coronary artery disease.
- Provides information on the time it takes for the blood to clot.
If you’ve had a 心脏病, you may have already undergone certain procedures to help you survive. Those same procedures can help diagnose your condition. 这些程序包括:
- 溶栓: Many STEMI 心脏病 patients will undergo thrombolysis, a procedure that involves injecting a clot-dissolving agent to restore blood flow in a coronary artery. This procedure is administered within a few (usually three) hours of a STEMI 心脏病.
- Coronary angioplasty/coronary artery bypass graft surgery (CABG): If thrombolysis treatment isn’t administered immediately after a 心脏病, many people will need to undergo coronary angioplasty 和 stenting or CABG to improve blood supply to the heart muscle.
