|Brief Title ICMJE||Noninvasive Imaging of Heart Failure: A Pilot Study|
|Official Title ICMJE||Noninvasive Imaging of Heart Failure|
- Heart failure is a common cardiovascular disorder whose incidence increases with age, affecting up to 10% of people older than 65 years of age. As the population ages, the prevalence and cost of heart failure will continue to rise. Researchers are interested in using noninvasive imaging methods to better understand the symptoms and effects of heart failure.
- To conduct a noninvasive comparative imaging study of individuals with heart failure.
- Individuals at least 18 years of age who have been diagnosed with heart failure (with at least mild symptoms and slight limitations on physical activity).
More than 9% of American men and close to 5% of women ages 60 to 79 years report a diagnosis of heart failure, where above the age of 80 years these figures increase to 13.8% and 12.2%, respectively. Projection into the middle part of this century suggests that, as the population ages, the prevalence and cost of heart failure will continue to rise. The primary aim of this proposal is to investigate noninvasive imaging methods for quantifying diffuse myocardial fibrosis with cardiac magnetic resonance imaging (CMR) in heart failure patients. The secondary aims are to investigate the association between diffuse fibrosis detected by CMR with left ventricular function, and examine the utility of multi-detector CT (MDCT) in detecting diffusion myocardial fibrosis.
