Home Blood Pressure Predicts Cardiovascular Events in Type 2 Diabetes Patients, Study Finds

A recent study has discovered that home blood pressure (BP) may predict the development of future cardiovascular events in patients with Type 2 Diabetes (T2D).

This research covered 1,081 T2D patients with an average age of 66 years old, where 45% of which were women from whom morning and evening blood pressure (BP) measurements were collected in triplicate for 14 consecutive days. 

None of the patients under study had any history of macrovascular complications. The research’s primary result was the development of first major cardiovascular event.

For an average follow-up of 7 years, there were 119 cardiovascular events recorded. Most of the reported cases were angina pectoris or non-fatal strokes, though five deaths and 2 heart failures happened.

Utilizing the unadjusted cox proportional hazards analyses, it was found that morning, evening, and clinical systolic BP (SBP) were significantly correlated with incident cardiovascular events in diabetes, with hazard ratios ranging from 1.11 to 1.21 accordingly.

With multivariate adjustments, however, revealed that only home morning systolic blood pressure (SBP) was independently and significantly associated with cardiovascular events. Notably, neither clinical SBP nor diastolic BP were indicative of cardiovascular event risk.

To the best of our knowledge, this retrospective cohort study of patients with T2D revealed, for the first time, the prognostic values of morning and evening BP for cardiovascular events.

The results may contribute to the development of guidelines and be valuable to clinicians involved in the management of patients with diabetes.

Home BP would be a better tool to assess cardiovascular risk associated with BP levels.
