TRAnscranial Doppler CErebral Blood Flow and Cognitive IMPAIRment in Heart Failure (TRACE-IMPAIR)

February 10, 2022 updated by: John Paul II Hospital, Krakow

TRAnscranial Doppler CErebral Blood Flow and Cognitive IMPAIRment in Patients With Heart Failure and Presence/Absence of Atherosclerotic Carotid Artery Stenosis

TRACE-IMPAIR is a prospective, clinical study of consecutive patients that evaluates the relationship between heart failure (HF) and cognitive impairment in relation to carotid and cerebral flow. The carotid and cerebral flow will be assessed using Doppler ultrasonography, and cognitive function will be estimated during routine neuropsychological tests.

It is an observational, three(natural)-group, single-center study. It is also an Academic Registry - the scientific activity of the Faculty of Medicine, Collegium Medicum, Jagiellonian University, and John Paul II Hospital.

Study Overview

Detailed Description

Circumstantial evidence suggests that cognitive dysfunction may occur in HF patients as often undiagnosed comorbidity. Cognitive dysfunction may aggravate HF symptoms and influence prognosis. Cognitive dysfunction may be a reason for inadequate self-care and poor symptom control (e.g., weight gain monitoring). In addition, it may affect medication compliance, leading to hospital readmissions and increased mortality. Brain tissue hypoxia, microemboli, silent strokes, and co-existing anemia have been implicated in contributing to cognitive dysfunction in HF. However, the role of cerebral flow impairment in these patients remains unclear. This uncertainty is mainly because previous studies included small patient groups, diverse imaging techniques, and neuropsychological tests. Furthermore, these studies were primarily conducted in the elderly, a potentially important confounder due to the effect of age on cognitive dysfunction. Particularly little data is available for younger patients (< 60 years).

This study aims to investigate the association of HF, carotid and cerebral flow, and cognitive impairment. Consecutive patients with HF with mildly reduced (HFmrEF) and reduced ejection fraction (HFrEF) will be included in the study. Echocardiography with routine measurements such as ejection fraction and stroke volume will be performed in each patient. The carotid and cerebral flow will be assessed on Doppler ultrasonography. Each patient will undergo cognitive function assessment using Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). The results in the index group (isolated HF) will be compared with those in a group of patients with HF and flow-limiting carotid stenosis (CS) against a control group (no HF, no CS).
