高血压、冠心病是老年人常见病,习惯上人们用药都是采用一日三次服用。近年来研究表明,这种服药方法并不恰当,提出应根据“生物钟”节律采取“时辰服药”。 近年来,国内外学者采用动态血压监测发现,正常人及高血压病人的血压都有昼夜波动规律,大多数人的血压在凌晨2—3时最低,上午8—10时及下午4—6时最高,从晚上6时起血压呈缓慢下降趋势。高血压病人,特别是老年病人,这种“日高夜低”更为显著,有明显的低谷与高峰。正因为如此,所以白天易发生出血性中风,夜间易发生缺血性中风。传统服药是一日三 Hypertension, coronary heart disease is a common disease in the elderly, people used to take medicine are used three times a day. In recent years, studies have shown that this method of medication is not appropriate, it should be based on “circadian rhythm” to take “when the hour medication.” In recent years, domestic and foreign scholars using ambulatory blood pressure monitoring found that both normal and hypertensive patients have circadian blood pressure fluctuations, most people’s blood pressure at 2-3 o’clock in the morning the lowest, 8-10 am and 4-6 pm The highest, from 6 pm blood pressure showed a slow downward trend. Hypertensive patients, especially elderly patients, this “day and night low” more significant, significant trough and peak. Because of this, so during the day prone to hemorrhagic stroke, ischemic stroke prone at night. Traditional medicine is three days a day
