寒冷的冬天,是中老年人心脑血管疾病及慢性肺疾病等的好发季节。当这些疾病发作前,一般常有信号(先兆),患者或家人若能认识这些信号,及时就医,明确诊断,积极治疗,可预防疾病的发作。故学会识别发病信号非常重要。 Cold winter is a good season for cardiovascular disease and chronic lung disease in the elderly. Before the onset of these diseases, there is usually a signal (aura). If the patient or family members can recognize these signals, seek timely medical attention, make a definite diagnosis and actively treat them, they can prevent the onset of the disease. Therefore, it is very important to learn to recognize the signal of the disease.
