目的：探讨非胰岛素依赖型糖尿病（ＮＩＤＤＭ）者动态血压水平及昼夜节律改变的特点。方法：行２４ｈ动态血压监测（ＡＢＰＭ）。结果：ＡＢＰＭ能客观地反映ＮＩＤＤＭ者血压的总体水平，但ＡＢＰＭ判断高血压的标准似较偶测血压为低；伴或不伴高血压的ＮＩＤＤＭ患者，均可存在血压昼夜变化差值减少，尤其是收缩压。结论：收缩压昼夜变化差值减少很可能是相当一部分ＮＩＤＤＭ者动态血压昼夜节律改变的特点
Objective: To investigate the changes of ambulatory blood pressure and circadian rhythm in non-insulin dependent diabetes mellitus (NIDDM). Methods: 24h ambulatory blood pressure monitoring (ABPM). Results: ABPM objectively reflected the overall level of blood pressure in NIDDM patients. However, the standard of ABPM for judging hypertension was lower than that of occasional blood pressure test. The difference of diurnal blood pressure between NIDDM patients with and without hypertension may be decreased, especially Is systolic blood pressure. Conclusion: The reduction of systolic blood pressure diurnal variation is likely to be a significant part of the characteristics of ambulatory blood pressure circadian rhythm in NIDDM
