Goal 2: Reduce Human Disease

Noninvasive biomarkers for characterizing cardiovascular disease

Critical Challenge

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? Critical Challenge (CC)

Details on the impact of addressing this CQ or CC

Phenotypical characterization of cardiovascular disease with computed tomography (CT) and magnetic resonance imaging (MR) to individualize targeted therapies for coronary artery and myocardial disease. Coronary artery disease is a major cause of patient death in the United States. Nonischemic myocardial disease includes entities with clinically heterogeneous presentations and is thus challenging to manage.

Feasibility and challenges of addressing this CQ or CC

Currently CT and MR technology allows dynamic evaluation of the perfusion and contractility of the heart. Quantitative measures of disease burden, such as atherosclerotic plaque composition and myocardial texture imaging biomarkers (such as T1 mapping, activation mapping, flow pattern analysis, delayed myocardial enhancement), are possible. Positron emission tomography (PET)/MR, which combines metabolic with functional evaluation, is currently available and facilitates the development of targeted molecular-imaging techniques. Metrics derived from these techniques may serve to stratify patients noninvasively and direct appropriate therapies. Such imaging methods address noninvasive evaluation of cardiovascular disease, including ischemic heart disease but also myocardial diseases that include secondary and infiltrative cardiomyopathies, hypertrophic cardiomyopathy, and organ rejection in the scenario of transplantation.
