Exploring the Relationship Between RV/LV T2 and OS-CMR SI Ratio with Exercise Capacity in Heart Failure Patients

Heart failure is a leading cause of mortality worldwide. Interventions for heart failure can be invasive, and imaging techniques focus mostly on cardiac structure and  its function rather than myocardial oxygenation, which plays a crucial role in heart failure. Oxygenation-sensitive cardiac magnetic resonance imaging (OS-CMR) is a non-invasive method to study myocardial oxygenation levels. With specific breathing maneuvers, OS-CMR can help detect ischemic heart disease by identifying areas of reduced myocardial oxygenation. Secondly, The 6-minute walk test (6MWT) assesses exercise capacity in heart failure patients ages 35-79 . The objective is to evaluate the relationship between OS-CMR imaging and 6MW distance and to identify additional biomarkers to understand the progression of disease.
