虽然大量流行病学研究显示传统方法测量的血压(门诊坐位水银血压计)与心血管病患病率及死亡率有关,但二者联系并不紧密。这可能由于个体对血压升高导致心血管损害的耐受具遗传差异,还可能因其它并存的危险因素影响,另一可能是门诊测定血压不能完全反应日常生活中真正的血压,这是因血压计本身精确性有限(尤其肥胖与老年人)。患者的警觉反应即所谓“白大衣性高血压”,还有24 h血压变异等因素的影响。大多数人,24 h血压变化很大,相差可达6.6 kPa(50 mmHg)以上,使门诊测值受极大限制。不少资料证明24h血压平均值较门诊血压测值与高血压器官损害更密切相关。因此,是否动态血压
Although a large number of epidemiological studies have shown that the blood pressure measured by the traditional method (outpatient sitting mercury sphygmomanometer) is related to the prevalence and mortality of cardiovascular diseases, the relationship between them is not very close. This may be due to individual genetic tolerance to cardiovascular damage caused by elevated blood pressure genetic differences, but also may be due to other coexisting risk factors, the other may be outpatient determination of blood pressure can not fully reflect the real blood pressure in daily life, which is due to blood pressure The meter itself has limited accuracy (especially obesity and the elderly). The patient’s alert response is called “white coat hypertension”, as well as 24 h blood pressure variation and other factors. Most people, 24 h blood pressure varies widely, a difference of up to 6.6 kPa (50 mmHg) above, so that the out-patient measurement is greatly limited. A lot of information to prove that the average blood pressure 24h higher than the measured blood pressure and hypertension are more closely related to organ damage. Therefore, whether or not ambulatory blood pressure
