Wearable Monitor in Patients With Syncope

Status Completed

Clinical Trial Summary

The main purpose of this study is to assess the reliability of a new patient's self-administered wearable watch-type BP monitor in detecting episodes of hypotensive (pre)syncope. Secondary aim regards the estimation of feasibility of this tool.

Clinical Trial Description

Background While ECG monitoring is a reliable and established method that allows to document bradycardia in a substantial proportion of patients affected by cardioinhibitory reflex syncope, the documentation of a transient hypotension is only seldom achieved in patients affected by hypotensive syncope. Conventional ambulatory blood pressure (BP) monitoring (ABPM) has important limitations due to the short period of monitoring (usually 24-48 hours) and the intermittent nature of BP measurements (usually every 15-20 min). The main purpose of this study is to assess the reliability of a new patient's self-administered wearable watch-type BP monitor in detecting episodes of hypotensive (pre)syncope. Secondary aim regards the estimation of feasibility of this tool. Method The study is a prospective intrapatient comparison during tilt testing between BP measured by mean of a wearable watch-type BP monitor (Omron HeartGuide 6410T, Omron Healthcare, Kyoto, Japan) and by mean of the standard methods for continuous finger BP monitoring (Finometer®, Finapres Medical Systems, Enchede, The Netherlands, and Task Force® monitor, CNSystem, Graz, Austria), based on the photoplethysmographic volume clamp method . Study design BP values observed during tilt testing baseline and at the time of impeding syncope will be measured by mean of the HeartGuide device and will be compared with the standard of reference of BP. BP will be recorded at rest at baseline, shortly after upright in tilting position (at stabilization), at the time of occurrence of impeding syncope (presyncope) or, alternatively at the time of maximum hypotensive effect, if syncope will not occur, and finally in the recovery period at the end of the test after returning in supine position. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
