PACE Cognition Proof-of-Concept Study

August 17, 2026 updated by: University of Minnesota

Impact of Physiologic Pacemaker Programming on Cognitive Function and Health Status in Patients With Symptomatic Bradycardia

This proof-of-concept study will evaluate whether physiologic pacemaker programming improves cognitive function and health status in patients with symptomatic bradycardia who require permanent pacemaker implantation.

Participants will be randomized to either standard pacemaker programming at 60 beats per minute or individualized physiologic rate pacing between 60 and 90 beats per minute using the myPACE algorithm. Cognitive function and health status will be assessed before pacemaker implantation and again at the routine 3-month pacemaker clinic visit.

The primary outcome is change in Montreal Cognitive Assessment total score. The secondary outcome is change in SF-36 mental component summary score.

Study Overview

Detailed Description

Cardiac pacing may improve cognition by restoring physiologic heart rates, enhancing cerebral perfusion, and improving overall cardiovascular function in patients with symptomatic bradycardia who require permanent pacemaker implantation. In current clinical practice, the lower pacing rate is commonly programmed to 60 beats per minute, which is below the normal resting heart rate in many adults.

PACE Cognition is a proof-of-concept study evaluating the impact of physiologic pacemaker programming on cognitive function and health status. Patients requiring permanent pacemaker implantation for bradycardia will be screened before device implantation. Interested and eligible patients will provide written informed consent before any study-specific procedures are performed.

Baseline cognitive and health-status assessments will be completed before pacemaker implantation. Cognitive function will be assessed using the Montreal Cognitive Assessment, a brief standardized screening instrument that evaluates multiple cognitive domains, including memory, attention, language, visuospatial ability, executive function, and orientation. Health status and functional well-being will be assessed using the SF-36 questionnaire, including the mental component summary score.

Participants will be randomized to either standard pacing at 60 beats per minute or individualized physiologic rate pacing between 60 and 90 beats per minute using the myPACE algorithm. Follow-up Montreal Cognitive Assessment and SF-36 assessments will be repeated at the routine 3-month pacemaker clinic visit to evaluate changes in cognitive performance and health status between the pacing strategies.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Montreal Cognitive Assessment Total Score
Time Frame: Baseline to 3 months after pacemaker implantation
Change in Montreal Cognitive Assessment total score from baseline to 3 months after pacemaker implantation will be compared between participants randomized to standard pacemaker programming at 60 beats per minute and participants randomized to physiologic pacemaker programming between 60 and 90 beats per minute using the myPACE algorithm. The Montreal Cognitive Assessment is scored from 0 to 30, with higher scores indicating better cognitive function.
Baseline to 3 months after pacemaker implantation

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Short Form 36 Health Survey Mental Component Summary Score
Time Frame: Baseline to 3 months after pacemaker implantation
Change in Short Form 36 Health Survey Mental Component Summary score from baseline to 3 months after pacemaker implantation will be compared between participants randomized to standard pacemaker programming at 60 beats per minute and participants randomized to physiologic pacemaker programming between 60 and 90 beats per minute using the myPACE algorithm. The Short Form 36 Health Survey Mental Component Summary score ranges from 0 to 100, with higher scores indicating better mental health and psychological well-being.
