  Purpose

Previous cross-sectional studies have demonstrated that blood pressure (BP) measurements at home (HBP) in the morning offer stronger predictive power for micro- and macrovascular complications in patients with type 1 and 2 diabetes than casual/clinic blood pressure measurements (CBP). The present study examined which of HBP or CBP provides the stronger predictive power for outcomes by comparing cumulative events between hypertensive and normotensive patients over 6 years in a prospective, longitudinal study of patients with type 2 diabetes.


Condition Intervention
Hypertension
Type 2 Diabetes
Device: blood pressure measurements based on HBP or CBP

Primary Outcome Measures:
  • Death [ Time Frame: Duration varied between individual patients and was as the period of time until MH or CH patient at baseline displayed a change to MN or CN, or until MN or CN patient at baseline displayed a change to MH or CH, respectively ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Microvascular complications [ Time Frame: Duration varied between individual patients and was as the period of time until MH or CH patient at baseline displayed a change to MN or CN, or until MN or CN patient at baseline displayed a change to MH or CH, respectively ] [ Designated as safety issue: Yes ]
  • Macrovascular complications [ Time Frame: Duration varied between individual patients and was as the period of time until MH or CH patient at baseline displayed a change to MN or CN, or until MN or CN patient at baseline displayed a change to MH or CH, respectively ] [ Designated as safety issue: Yes ]

Enrollment: 400
Study Start Date: November 1997
Study Completion Date: February 2007
Primary Completion Date: February 2007 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
1 Morning hypertension and normotension
Based on HBP, subjects were divided into MH and MN patients
Device: blood pressure measurements based on HBP or CBP
To clarify which of HBP or CBP provides the stronger predictive power for the outcomes, the 400 patients were classified as with or without hypertension based on HBP and CBP measurements at baseline
2 Clinic hypertension and normotension
Based on CBP, subjects were divided into CH and CN patients
Device: blood pressure measurements based on HBP or CBP
To clarify which of HBP or CBP provides the stronger predictive power for the outcomes, the 400 patients were classified as with or without hypertension based on HBP and CBP measurements at baseline
