冬季是心脑血管疾病的突发、高发季节,高血压患者应高度重视冬季血压防控工作,防止血压上蹿引发心脑血管意外。首先,隆冬时节,机体受寒冷刺激,交感神经兴奋性增高,体内儿茶酚胺分泌增多,使人的肢体、皮肤血管收缩,导致心率加快,心脏负荷增大,使心脑血管痉挛收缩,血压升高,心脑耗氧量增加。心脑严重缺血、缺氧,易导致心梗和中风。
Winter is a sudden onset of cardiovascular and cerebrovascular diseases, high season, high blood pressure patients should attach great importance to prevention and control of blood pressure in winter to prevent blood pressure caused by cardiovascular and cerebrovascular accidents. First, the winter season, the body by the cold stimulation, increased sympathetic excitability, the body increased catecholamine secretion, the human limbs, skin vasoconstriction, leading to heart rate, heart load increases, so that cardiovascular and cerebrovascular vasospasm, elevated blood pressure, Cardiac and brain oxygen consumption increased. Severe cerebral ischemia, hypoxia, easily lead to myocardial infarction and stroke.
