目前研究表明,在原发性高血压(EH)的药物治疗中,持续、有效地降低血压,减少血压的波动,可以减轻靶器官的远期损害。缬沙坦作为非肽类血管紧张素Ⅱ受体拮抗剂,它的降压作用在以往的研究中已得到证实〔1〕,为了进一步了解其降压的平稳性,本研究应用血压平滑指数(smoothnessindex The current study shows that in the treatment of essential hypertension (EH) drug treatment, sustained and effective blood pressure, reduce blood pressure fluctuations, can reduce long-term target organ damage. Valsartan as a non-peptide angiotensin Ⅱ receptor antagonist, its antihypertensive effect in the previous study has been confirmed 〔1〕, in order to further understand the stability of its antihypertensive, the study using the blood pressure smoothing index smoothnessindex
