If elderly people develop cardiovascular blockage, they need to actively go to the hospital to find the primary cause and to improve the relevant tests. To determine the location and size of the blockage and the stability of the atherosclerotic plaque in the blocked vessel, for example, an 18-lead ECG, cardiac function, cardiac enzymes, ambulatory ECG, as well as cardiac flat panel exercise, coronary angiography and coronary CT. If the blockage is relatively severe, the blockage area is large, and the plaque is unstable, PCI treatment or cardiac stenting or bypass surgery can be performed. However, for elderly people, if the blockage is not large or the plaque is stable, they can be treated with oral medication. You can take nitrates, or aspirin, clopidogrel, tigretol and statin lipid-lowering drugs in combination, which can improve the symptoms of cardiovascular blockage. However, once cardiovascular blockage occurs in the elderly, regular review and strict follow-up is required.
