10 Questions
- What are the expected responses for proportional blood pressure drops at night based on the daytime period?
Attenuated response (0–10% nocturnal decrease), normal response (10–20% nocturnal decrease), marked response (above 20% decrease), and reverse response (increase in blood pressure instead of expected nocturnal decrease).
- What does attenuated or reverse response indicate?
Exacerbated sympathetic activity, which may be present in dysautonomia, and has been associated with increased mortality.
- What can ABPM indicate and select patients for?
ABPM can indicate cardiovascular autonomic dysfunction abnormalities and is able to select patients for a deeper assessment of dysautonomia.
- What can ABPM be especially useful in detecting, usually not detected with the usual blood pressure measurements?
ABPM can be especially useful in detecting nocturnal hypertension (an important predictor of cardiovascular events) and forms of early or postprandial orthostatic hypotension.
- What does the presence of nocturnal hypertension increase the risk of?
Daytime hypotension, among other things, as a result of increased nocturnal excretion of natriuretic hormone.
What are the effects of attenuated or reverse response on blood pressure, and what conditions are they associated with?
Attenuated or reverse response shows exacerbated sympathetic activity and may be present in dysautonomia, and has been associated with increased mortality.
What does the presence of nocturnal hypertension increase the risk of, and how does it relate to daytime hypotension?
The presence of nocturnal hypertension may increase the risk of daytime hypotension, as a result of increased nocturnal excretion of natriuretic hormone.
What can ABPM indicate regarding cardiovascular autonomic dysfunction abnormalities, and how can it be useful in patient assessment?
ABPM can indicate cardiovascular autonomic dysfunction abnormalities and is able to select patients for a deeper assessment of dysautonomia.
What is the significance of nocturnal hypertension in terms of cardiovascular events, and what can ABPM be especially useful in detecting?
Nocturnal hypertension is an important predictor of cardiovascular events, and ABPM can be especially useful in detecting it.
What are the expected responses for proportional blood pressure drops at night based on the daytime period?
The expected nocturnal decrease responses are: attenuated response (0–10% nocturnal decrease), normal response (10–20% nocturnal decrease), marked response (above 20% decrease), and reverse response (increase in blood pressure instead of expected nocturnal decrease).
Test your knowledge on the effects of daytime and nocturnal autonomic balance on blood pressure. Learn about the different expected nocturnal decrease responses and how they affect overall health.
