Problems in the Assessment of Blood Pressure: The Framingham Study
Why the study?
Does an averaged series of blood pressure measurements improve the prediction of future cardiovascular disease compared to a single casual measurement in a general cohort?
Population
5,209 men and women from the Framingham cohort
Comparison
Averaged series of blood pressure measurements vs Single casual blood pressure measurement
Design
Cohort
Follow-up
18 years

Implication
Single casual BP measurement suffices for CVD prediction in cohorts; leaves open whether averaged readings improve clinical risk stratification.

I
Intervention
Averaged series of blood pressure measurements
C
Comparator
Single casual blood pressure measurement
O
Outcome
Future cardiovascular disease (cardiovascular sequelae of hypertension)hard clinical
A single casual blood pressure measurement is highly predictive of future cardiovascular risk, validating its use in clinical practice despite the slight predictive advantage of averaged measurements.
