Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Death

    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

Secondary Outcomes (2)

  • Microvascular complications

    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

  • Macrovascular complications

    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

Study Arms (2)

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

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

Interventions

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
