In the past few years non-invasive blood pressure monitoring has become increasingly popular in the belief that this approach: can provide accurate mean blood pressure values over a 24-h period or through the day and these values may define better than the casual values the severity of hypertension and its related risk of developing cardiovascular morbidity and mortality. In this paper a number of problems concerning non-invasive ambulatory blood pressure monitoring in hypertension will be reviewed. First, evidence will be shown that blood pressure measurements at intervals up to 30 min can provide a 24-h blood pressure mean similar to that obtained by continuous analysis of the blood pressure tracing, which demonstrates that intermittent readings do not represent a limitation of automatic blood pressure monitoring. Then, it will be shown that the periodical cuff inflations of automatic or semi-automatic blood pressure monitoring may not trigger an alarm reaction or disturb patients' sleep. However, these advantages must be balanced against other still unverified aspects of these new techniques: the inability of intermittent blood pressure readings to evaluate accurately blood pressure variability, which may be a determinant of the overall risk profile, the error inherent in non-invasive measurements of blood pressure and the limited prospective evidence that average 24-h or daytime blood pressure values indeed correlate with the development of target organ damage better than casual blood pressure values do.
在过去几年中，无创血压监测越来越受欢迎，因为人们相信这种方法：能够在24小时或一整天内提供准确的平均血压值，并且这些值可能比偶然测量的值更能明确高血压的严重程度及其发生心血管疾病和死亡的相关风险。本文将综述有关高血压无创动态血压监测的一些问题。首先，有证据表明，每隔30分钟进行一次血压测量所得到的24小时平均血压，与通过连续分析血压描记图所获得的结果相似，这表明间歇性读数并非自动血压监测的局限。其次，将表明自动或半自动血压监测的周期性袖带充气可能不会引发警报反应或干扰患者睡眠。然而，这些优点必须与这些新技术其他尚未得到验证的方面相权衡：间歇性血压读数无法准确评估血压变异性，而血压变异性可能是总体风险状况的一个决定因素；无创血压测量存在固有误差；以及前瞻性证据有限，即平均24小时或日间血压值确实比偶然血压值更能与靶器官损害的发生相关。
