Cerebral infarction is a kind of middle-aged and old-aged disease, and with the progress of population aging in China, cerebral infarction becomes more and more a threat to human health. In addition, cerebral infarction is characterized by high incidence, high disability, high mortality and high recurrence rate, and there is a great risk of recurrence even after recovery from one treatment of cerebral infarction, so prevention of recurrence is especially important. According to the progress of domestic and foreign research, “ASA” is fundamental in the prevention of cerebral infarction patients, Antiplatelet: antiplatelet therapy, Statin: statin, Antihypertension: anti-hypertension. Antiplatelet: The most commonly used antiplatelet drugs are aspirin and clopidogrel, etc. Statin: Statin has been widely used in the prevention and treatment of coronary heart disease and cerebral infarction since 2006, from the previous treatment of hyperlipidemia to anti-atherosclerosis, plaque stabilization and plaque reversal. Commonly used statins are atorvastatin (Lipitor), resulvastatin, etc.; Antihypertension Anti-hypertension treatment: hypertension is an independent risk factor for cerebral infarction, so patients with hypertensive cerebral infarction must have their blood pressure well controlled. Of course, these treatments are fundamental to prevent recurrence of cerebral infarction. Other aspects are also particularly important, such as lifestyle changes, quitting smoking and limiting alcohol, appropriate activities, and maintaining a relatively good mood. Patients with diabetes also need to control their blood sugar, and patients with carotid stenosis need to undergo carotid stenting and so on. Only through comprehensive treatment can we get good results. If you are a patient with cerebral infarction, you can check the above treatment and see if you have done “ASA”. Many patients or some doctors rely completely on proprietary Chinese medicine, and Chinese medicine has certain strengths, but do not overly believe and rely on it. On the basis of these treatments, you can choose a proprietary Chinese medicine. Some doctors give patients two to three kinds of pCms at the same time, which are mostly multiple ingredients, and it is unreasonable and wasteful to take two or three kinds of pCms together.
