It is well known that cerebral infarction is a major disease that seriously endangers the lives and health of middle-aged and elderly people, with a very high rate of death and disability. Once the disease develops, there are limited options for effective treatment. Thrombolytic therapy may be one of the more aggressive and effective treatment measures, but it has its indications, contraindications and corresponding risks. The golden time for thrombolytic therapy is within 3 hours, so it is important to seek medical attention as soon as symptoms of cerebrovascular disease appear.
