The Combination of Non-dipper Heart Rate and High Brain Natriuretic Peptide Predicts Cardiovascular Events: The Japan Morning Surge-Home Blood Pressure (J-HOP) Study

What Was Tested

This observational study looks at BNP (Nesiritide) in the context of low blood pressure and orthostatic hypotension.

The researchers hypothesized that the association between the dipping heart rate (HR) pattern and cardiovascular (CV) events differs according to the brain natriuretic peptide (BNP) level.

Who Took Part

According to the abstract, 1,369 patients were involved.

The age groups tagged for this paper are middle-aged adults, older adults and people over 80, both men and women.

The researchers examined a subgroup of 1,369 patients from the Japan Morning Surge Home Blood Pressure study; these were patients who had CV risk factors and had undergone ambulatory blood pressure (BP) monitoring.

The researchers divided the patients into four groups according to their HR dipper status (dipping or non-dipping) and BNP level (normal or high).

How the Study Was Run

HR non-dipping status was defined as (awake HR - sleep HR)/awake HR <0.1, and high BNP was defined as ≥35 pg/ml.

What Was Measured

The researchers hypothesized that the association between the dipping heart rate (HR) pattern and cardiovascular (CV) events differs according to the brain natriuretic peptide (BNP) level.

The subject headings attached to it are Biomarkers, Blood Pressure, Cardiovascular Diseases, Circadian Rhythm, Heart Disease Risk Factors, Heart Rate and Hypertension.

The authors tagged it with the keywords brain natriuretic peptide, cardiovascular event and non-dipper heart rate.

What This Means in Plain Language

This is an observational study of BNP (Nesiritide) in 1,369 patients in people with low blood pressure and orthostatic hypotension.

With several hundred people or more, it is a fairly large study for this kind of research.

Its findings take up roughly 5 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.

The publication is from 2020 (American journal of hypertension), a journal based in United States.
