美国亚特兰大消息:美研究人员Thomas Robertson 等人对1,209例卒中病例的复查,确定首次出现神经症状时发病次数的分布情况,结果是清晨(上午3～8时)卒中发生率很低,但在上午9时突然升高,持续到上午11时。 Robertson说:“生物节奏与卒中的发生有密切联系。这一信息将有助于设计预防卒中的新方案。”他推测:早晨刚醒时,血中高水平的肾上腺素引起血管收缩,从而增强了血小板的聚集作用。“了解每日的时间与卒中发生关系,就可确定引起卒中发生的机制,从而可能研制更有效的预防药物。
Atlanta, GA: US researchers Thomas Robertson et al. Performed a review of 1,209 stroke cases to determine the frequency of first-onset neurological symptoms. As a result, the incidence of stroke was low in the morning (3-8 am) but in the morning Suddenly increased at 9 am, continuing until 11 am. “The biological rhythm is closely linked to the onset of stroke,” Robertson said, “This information will help design new programs for stroke prevention.” He speculated that the high levels of epinephrine in the blood caused vasoconstriction during morning waking and thus increased Aggregation of platelets. Knowing the timing of the day versus stroke can identify the mechanisms that lead to stroke, making it possible to develop more effective preventative drugs.
