Comparison of ambulatory blood pressure monitoring among patients with postural orthostatic tachycardia syndrome, autonomic dysfunction, and controls

TL;DR

This study compares blood pressure monitoring in patients with autonomic dysfunction and finds varying results depending on the condition.

Contribution

The study reveals that blood pressure monitoring may be less useful for POTS patients compared to others with autonomic dysfunction.

Findings

76% of AD patients without POTS had uncontrolled blood pressure.

Only 19% of POTS patients had uncontrolled blood pressure.

ABPM may provide less value for POTS patients.

Abstract

The utility of ambulatory blood pressure monitoring (ABPM) among patients with various forms of autonomic dysfunction (AD) is unknown. Twenty-four-hour ABPM among patients with postural orthostatic tachycardia syndrome (POTS), AD without POTS, and control patients without AD were compared. Patients with AD without POTS had high rates of uncontrolled blood pressure (76%), whereas 19% of patients with POTS had uncontrolled blood pressure, suggesting ABPM may provide less value among patients with POTS.
