During the new coronavirus epidemic, the virus is running everywhere, how should patients with coronary heart disease protect themselves? The first principle: try to keep the plaque in the coronary artery lesion area stable. To do this, you can do the following things: 1, do not overwork, excessive anxiety; do not stay up late; calm and relaxed. 2.Don’t drink alcohol or smoke excessively; pay attention to indoor ventilation; do moderate indoor exercise. 3.Take basic medications on time. Statins or statins combined with ezetimibe. Because of the many factors affecting the stability of plaque, the level of LDL-C is an internationally recognized indicator, the purpose is to reduce LDL-C to a lower level, at least less than 1.8 mmol/l, preferably less than 1.4 mmol/l. After the stability of atherosclerotic plaque is greatly improved, it is less likely to have acute coronary events, greatly reducing the chance of having to go to the hospital. The chance of having to go to the hospital is greatly reduced, thus reducing the possibility of cross-infection. Antiplatelet drugs, such as aspirin, prevent thrombosis. Because acute coronary events occur in addition to the problem of atheromatous plaque stability, there is a more immediate problem of thrombosis on top of the ruptured plaque. Aspirin is combined with clopidogrel or prasugrel on top of aspirin. The risk of thrombosis is greater in patients who have had recent conservative treatment for infarction and within 1 year of stenting for coronary intervention, as well as in patients who are still on conservative treatment for multiple recent angina attacks. Do not stop or reduce the dose easily. Change the dose must listen to medical advice. 4. If you have recurrent episodes of unstable angina or acute myocardial infarction, do not be afraid to go to the nearest hospital immediately for appropriate examination, diagnosis and treatment, and if necessary, emergency intervention!
