If the cardiovascular lumen stenosis area reaches 30%, regular treatment by medication is necessary and coronary angiography of the cardiovascular arteries should be done regularly for a clear diagnosis and definitive examination. Usually within 0.5-1 year, CT or coronary angiography of the coronary arteries of the heart should be completed. In addition, you should take certain anti-platelet aggregation drugs, such as aspirin, clobigrel, tigretol, etc. You should also take statin lipid-lowering drugs, such as Lipitor and Cortisol. Beta-blockers such as metoprolol tartrate and metoprolol succinate can also be taken. Then add ACEI-type drugs to prevent ventricular remodeling, such as captopril and benazepril, all of which are very effective for cardiovascular stenosis.
