Cardiac Morphology and Function in Individuals With Autonomic Dysreflexia

Starting soon

Conditions studied: Autonomic Dysreflexia, Spinal Cord Injuries and Disorders (SCI/D), Cardiac Remodeling

In brief

This case-control study aims to investigate left ventricular remodeling in individuals with chronic spinal cord injury or disease (SCI/D) (≥10 years) and autonomic dysreflexia (AD) who have no prior cardiovascular history. The primary objective is to compare cardiac changes between 24 individuals with high-level SCI/D (above Th6) who have AD and 24 individuals with low-level SCI/D (below Th10) who do not have AD. A secondary objective examines how factors such as age, sex, injury duration, and physical activity are associated with cardiac remodeling. All 48 participants will undergo cardiac MRI as well as blood measurement of B-type natriuretic peptid to assess cardiac morphology and function. The findings could shed light on a potentially underestimated cardiovascular risk factor in the SCI/D population.
