  1. Within-subject diastolic blood pressure variability : implications for risk assessment and screening.

    Article - En anglais

    Because of variability in diastolic blood pressure within an individual, repeated measurements increase precision in assessing an individual's underlying mean pressure and so also aid risk classification.

    Data from a cohort of 11,299 middle-aged men is used to model the variability in diastolic pressure between annual measurements.

    A simple model with pressure normally distributed about an underlying mean with standard deviation increasing with level fits the data very well.

    In modelling risk of cardiovascular mortality, a strong association is found with observed diastolic pressure level but not to trends in or variability between observed values.
