Reducing Cognitive Impairment by Management of Heart Failure as a Modifiable Risk Factor (Cog-HF)

August 9, 2024 updated by: Baker Heart and Diabetes Institute

Reducing Cognitive Impairment by Management of Heart Failure as a Modifiable Risk Factor: the Cog-HF Trial

This study will test the feasibility and effectiveness of an innovative model of care for cognitively impaired patients with heart failure. This program aims to improve cognition, reduce dementia risk and cardiovascular events, and will be supported by innovative digital technology for wide scale rollout and implementation. Findings from this research will transform the way healthcare is delivered to cognitively impaired patients with heart disease who have a very high risk of developing dementia.

Description

Inclusion Criteria:

  1. Hospitalised with HF as primary or secondary diagnosis.
  2. At least mild cognitive impairment (CI) based on Montreal Cognitive Assessment (MoCA) on hospital discharge.

Exclusion Criteria:

  1. Unable to provide written consent; requiring palliative care; or participating in another RCT
  2. Recovery of cognitive function shortly after hospital discharge: to ensure that we only include patients with "true" CI, any patients with a repeated MoCA>25 at 2 weeks post-discharge will be excluded.
  3. Terminal illness (eg. cancer) that may influence 12-month prognosis.

How is the study designed?

Design Details

  • Primary Purpose: Prevention
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Usual care
Usual care patients will continue with the hospital follow-up plan and routine preventive care after hospital discharge.
Experimental: Intervention
Intervention patients will receive a disease management program in addition to the usual care.

The components of our DMP include:

  1. Intensive post-discharge education
  2. Home surveillance of signs and symptoms will be reviewed (weekly in the first month and monthly thereafter) in a telehealth consultation with patient and/or carer.
  3. Medical treatment involves a planned up-titration of cardioprotective medications that will proceed in the absence of advice from the general practitioner (GP) to the contrary. Close observation and frequent appointments are organised by the nurse with the patient's GP during up-titration period.
  4. Exercise program delivered by an exercise physiologist
  5. Maintenance phase of the DMP: During this maintenance phase, Intervention patients should have been fully transitioned to home care where they are managed by their GP at optimal doses of their medications. Repeated education and exercise guidance will continue with the carer, supported by our cardiac nurse and exercise physiologist via telehealth consultation bimonthly.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in MOCA score
Time Frame: 12 months
Greater Montreal Cognitive Assessment (MOCA) score (ranging 0-30) is better
12 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in cardiac function
Time Frame: 12 months
Cardiac function will be measured by echocardiography. Left ventricular global longitudinal strain will be the primary measure of cardiac function.
12 months
Change in 6-minute walk distance
Time Frame: 12 and 24 months
Functional capacity will be based on 6-minute walk test
12 and 24 months
Change in quality of life
Time Frame: 12 and 24 months
Quality of life specific to heart failure symptoms will be measured using a disease-specific quality of life questionnaire: Kansas City Cardiomyopathy Questionnaire
12 and 24 months
Change in MOCA score
Time Frame: 24 months
Greater Montreal Cognitive Assessment (MOCA) score (ranging 0-30) is better
24 months
Change in brain volume via MRI measurement
Time Frame: 24 months
24 months
Change in hand grip strength
Time Frame: 12 and 24 months
12 and 24 months
Change in heart failure classification
Time Frame: 12 and 24 months
Based on New York Heart Association classification
12 and 24 months
