Cardiovascular mostly refers to the coronary arteries, and whether its blockage is treated conservatively or not needs to be decided according to the degree of blockage and the severity of symptoms. For coronary artery vessel blockage of less than 75%, the symptoms are mild, can be drug conservative treatment, coronary artery blockage of more than 75% need to be treated by interventional stenting or coronary artery bypass surgery. For most patients with chronic coronary artery disease, coronary artery vessel stenosis of 75% or less, angina symptoms are not serious, you can take conservative treatment, generally oral anticoagulant drugs aspirin enteric-coated tablets, lipid regulating or plaque stabilizing drugs simvastatin or atorvastatin calcium tablets, expanding coronary arteries nitrate drugs, such as isosorbide nitrate tablets. Patients with coronary artery disease also need conservative treatment when interventional therapy cannot be completed and they are not able to undergo coronary artery bypass surgery. Conservative treatment is needed for older people, such as those over 80 or 90 years of age, those who are not in good health, or those who have organ failure and cannot tolerate coronary vascular intervention or bypass surgery. Interventional stenting is required for 75% or more cardiovascular blockage, and bypass surgery is required for more complicated cardiovascular stenosis, if the physical condition permits. Therefore, whether cardiovascular blockage can be treated conservatively needs to be decided according to the specific situation, and under the guidance of the doctor through the relevant examination to assess and take the correct treatment measures to avoid delaying the condition.
