Key result
Increased ambulatory blood pressure variability, measured by standard deviation and coefficient of variation for systolic, diastolic, and mean arterial pressure, was associated with an increased risk of all-cause mortality.
Why the study?
Do ambulatory blood pressure measures of variability predict all-cause mortality in hypertensive patients?
Cohort (n=2,015)
No
Do ambulatory blood pressure measures of variability predict all-cause mortality in hypertensive patients?
Ambulatory blood pressure measures of variability, such as standard deviation and coefficient of variation, are reproducible and predict all-cause mortality, whereas the common definition of dipping status is not reproducible.
No takes yet. Share an insight, caveat, or question.
Should not yet change hypertension management; extends observational data on ambulatory BP variability but requires prospective validation.
Edmond S. Malka (2011) conducted a cohort in Hypertension (n=2,015). Ambulatory blood pressure variability vs. Lower blood pressure variability was evaluated on All-cause mortality. Increased ambulatory blood pressure variability, measured by standard deviation and coefficient of variation for systolic, diastolic, and mean arterial pressure, was associated with an increased risk of all-cause mortality.
