动态血压监测(ABPM)诸指标与难治性高血压病人心、脑、肾损害的相关性,可做其预测因子和研究工具。大量研究证明:24h平均动态血压、日间血压均值、夜间血压均值与心血管并发症相关性较偶测血压为优;夜间血压降低减弱或消失的难治性高血压病人与较高的心血管意外发生率相关;血压变异性与心血管损坏的严重性相关,而不依赖于血压水平;血压负荷是比血压水平更为准确的心血管危险预测指标;ABPM在预测难治性高血压无症状脑血管损害方面较诊室随测血压为优;微量清蛋白尿是原发性高血压早期肾脏结构和功能改变的标志,尿清蛋白分泌率与24h收缩压和舒张压及24h日间、夜间平均血压显著相关。
Ambulatory blood pressure monitoring (ABPM) indicators and refractory hypertensive patients with heart, brain, kidney damage correlation, can do its predictors and research tools. A large number of studies have shown that: 24h average ambulatory blood pressure, mean daytime blood pressure, nocturnal mean blood pressure and cardiovascular complications compared with occasional blood pressure is superior; nocturnal decrease or disappearance of blood pressure decreased refractory hypertensive patients and higher cardiovascular Unexpected incidence of BP; Variability of blood pressure correlates with severity of cardiovascular damage, independent of blood pressure level; Blood pressure load is a more accurate predictor of cardiovascular risk than BP; ABPM is not predictive of asymptomatic hypertension Microvascular albuminuria is a marker of structural and functional changes of early renal in patients with essential hypertension. Urinary albumin secretion rate was correlated with 24h systolic and diastolic blood pressure and 24-day and nighttime average Blood pressure was significantly correlated.
