[24 hours ambulatory blood pressure in impaired glucose tolerance patients]

We investigated the change of 24 hours ambulatory blood pressure (ABPM) in impaired glucose tolerance (IGT) patients. 40 IGT patients were divided into two group: normotension and hypertension groups. Each group was matched with normal glucose tolerance (NGT) and non-insulin-dependent diabetes mellitus (NIDDM) group. All the patients were subjected to ABPM and biochemical index examination. The profile of ABPM in IGT patients with or without hypertension was investigated. The change of the 24 hours blood pressure in both normotensive and hypertensive IGT patients was similar with NGT, but there was a tendency that night blood pressure was increased and nocturnal blood pressure was decreased in IGT. The change of ABPM in those with abnormal circadian rhythm was elevated night blood pressure.
