高血压所造成的心血管疾病罹患率和死亡率很高,因而强调高血压是引起心血管疾病最常见、最主要的易患因素。近年来,高血压病的预防医学日益受重视。降压治疗能防止出血性和缺血性脑卒中的发生并降低病死率。当前的问题是对脑卒中的防治和研究十分不够,各科医务人员之间的协作也不好,对无症状的轻症或老年性高血压病的治疗价值目前尚未肯定。抗高血压药物迭有问世,但无理想的。国外对β肾上腺素能性受体(以下简称β受体)阻滞剂防治高血压的研究颇盛行,其降压机理尚无一致意见,唯在国内使用和研究尚少。为了使患者能接受长期规律性治疗,研制有一定疗效、副作用少的长效降压药,已 Hypertension causes high rates of cardiovascular morbidity and mortality, emphasizing that hypertension is the most common and predominant predisposing factor for cardiovascular disease. In recent years, prevention medicine of hypertension is paid more and more attention. Antihypertensive treatment prevents hemorrhagic and ischemic stroke and reduces mortality. The current problem is that the prevention and research of stroke is not enough, and the collaboration between medical staff in different departments is also not good. The treatment value of asymptomatic mild or senile hypertension is not yet confirmed. Anti-hypertensive drugs have come out, but no ideal. Abroad, β-adrenergic receptor (hereinafter referred to as β-receptor) blockers prevention of hypertension quite popular, the antihypertensive mechanism is still unanimous opinion, only in domestic use and research is still small. In order to enable patients to accept long-term regular treatment, the development of a certain effect, less side effects of long-acting antihypertensive drugs, has
