Cerebrovascular disease not only has high morbidity, disability, and mortality rates, but also has a high recurrence rate. A significant proportion of stroke patients have a second or even a third stroke. Therefore, a stroke patient who recovers at home is at risk of having another stroke. Usually the second stroke is more serious than the first stroke and the mortality rate is much higher than the first stroke, so it is necessary to send the patient to the hospital and get timely treatment. A patient recovering at home may have another stroke if the following conditions occur: increased weakness of the paralyzed limb; numbness of the paraplegic body, or numbness and weakness of the other limb; unclear speech or stuttering; choking and coughing on water, difficulty swallowing; unstable walking, vertigo attacks with vomiting; severe headache and vomiting, or even coma and seizures. At this time, it is necessary to send to the hospital immediately. In addition, stroke patients with fever, coughing and phlegm, or abdominal pain and diarrhea, or palpitations, precordial pain, chest tightness and other symptoms, indicating that the patient has other internal diseases, should also be immediately sent to the hospital for examination and treatment.
