Cardiovascular risk prediction based on home blood pressure measurement: The Didima Study
Key result
Home blood pressure measurement predicted cardiovascular events (unadjusted HR 1.034 per 1 mmHg systolic increase, P<0.001) but demonstrated no prognostic superiority over office blood pressure.
Why the study?
Does home blood pressure measurement improve the prediction of cardiovascular risk compared to office blood pressure measurement in the general population?
Population
662 adults from the general population of the Didima area in Greece, mean age 54.1 +/- 17.6 years.
Comparison
Home blood pressure (HBP) measurement (3 days) vs Office blood pressure measurement
Design
Cohort
Follow-up
8.2 +/- 0.2 years

Implication
Home blood pressure adds no prognostic value over office readings in this cohort; leaves open superiority in refined risk models or other populations.

Home blood pressure measurement did not demonstrate prognostic superiority over office blood pressure measurement for predicting cardiovascular events in this general population cohort.
Cite This Study
Stergiou et al. (2007) conducted a cohort in Cardiovascular risk (n=662). Home blood pressure measurement (HBP) vs. Office blood pressure measurement (OBP) was evaluated on Fatal and non-fatal cardiovascular events (HR 1.034, p=<0.001). Home blood pressure measurement predicted cardiovascular events (unadjusted HR 1.034 per 1 mmHg systolic increase, P<0.001) but demonstrated no prognostic superiority over office blood pressure.
