Questions and Answers

  1. 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).

  1. What does attenuated or reverse response indicate?

Exacerbated sympathetic activity, which may be present in dysautonomia, and has been associated with increased mortality.

  1. 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.

  1. What can ABPM be especially useful in detecting, usually not detected with the usual blood pressure measurements?

<p>ABPM can be especially useful in detecting nocturnal hypertension (an important predictor of cardiovascular events) and forms of early or postprandial orthostatic hypotension.</p> Signup and view all the answers

  1. What does the presence of nocturnal hypertension increase the risk of?

<p>Daytime hypotension, among other things, as a result of increased nocturnal excretion of natriuretic hormone.</p> Signup and view all the answers

What are the effects of attenuated or reverse response on blood pressure, and what conditions are they associated with?
