Abstract

The purpose of this study was to determine if ambulatory blood pressure measurement predicted total and cardiovascular mortality over and beyond clinic blood pressure measurement and other cardiovascular risk factors; 5292 untreated hypertensive patients referred to a single blood pressure clinic who had clinic and ambulatory blood pressure measurement at baseline were followed up in a prospective study of mortality outcome. Multiple Cox regression was used to model time to total and cause-specific mortality for ambulatory blood pressure measurement while adjusting for clinic blood pressure measurement and other risk factors at baseline. There were 646 deaths (of which 389 were cardiovascular) during a median follow-up period of 8.4 years. With adjustment for gender, age, risk indices, and clinic blood pressure, higher mean values of ambulatory blood pressure were independent predictors for cardiovascular mortality. The relative hazard ratio for each 10-mm Hg increase in systolic blood pressure was 1.12 (1.06 to 1.18; P <0.001) for daytime and 1.21 (1.15 to 1.27; P <0.001) for nighttime systolic blood pressure. The hazard ratios for each 5-mm Hg increase in diastolic blood pressure were 1.02 (0.99 to 1.07; P =NS) for daytime and 1.09 (1.04 to 1.13; P <0.01) for nighttime diastolic pressures. The hazard ratios for nighttime ambulatory blood pressure remained significant after adjustment for daytime ambulatory blood pressure. These results have 2 important clinical messages: ambulatory measurement of blood pressure is superior to clinic measurement in predicting cardiovascular mortality, and nighttime blood pressure is the most potent predictor of outcome.

  • Some but not all studies have suggested that nighttime blood pressure is the strongest predictor of death.

    “Some 4,6,9,11 but not all studies 5,10 have suggested that nighttime blood pressure is the strongest predictor of death.”
  • The superiority of nighttime blood pressure over daytime blood pressure has been observed in other previous studies.

    “The superiority of nighttime blood pressure over daytime blood pressure has been observed in other previous studies, 4,9,11,13,14,35,36”
  • High nighttime blood pressure (lack of nocturnal blood pressure dipping) is a sensitive indicator for cardiovascular mortality, with 21% greater risk for each 10-mmHg increase in nighttime systolic blood pressure and 9% greater risk for each 5-mmHg increase in nighttime diastolic blood pressure.

    “The morning BP surge is not the only risk, as high nighttime BP (lack of nocturnal BP dipping) is a sensitive indicator for CV mortality, with 21% greater risk for each 10-mmHg increase in nighttime systolic BP and 9% greater risk for each 5-mmHg increase in nighttime diastolic BP (99).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
