Stenting is required in cases of acute myocardial infarction and persistent angina pectoris in the heart.
1. Acute myocardial infarction is a strong indication for stent placement. Sudden and complete occlusion of the coronary arteries, resulting in myocardial injury, ischemia, necrosis, must be installed in the first time cardiac stents, as soon as possible to open the blood vessels, is the most direct method.
2. Intractable angina. For example, moderate to severe stable angina pectoris, unstable angina pectoris, the effect of ordinary drug conservative treatment is not good, coronary angiography found that there is a serious stenosis, but also need to install a stent in a timely manner, to prevent myocardial damage, ischemia further aggravated by triggering myocardial infarction.
In conclusion, the need for stenting needs to be assessed according to the results of coronary angiography and the underlying conditions.
