Research Summary:

Acute myocardial infarction, known as a heart attack, occurs when blood supply to the heart muscle is interrupted. This can destroy the heart cells and severely compromise pumping action, resulting in progression toward heart failure. Dr. Ghugre’s research focus is to utilize advanced cardiac MRI biomarkers to characterize the post-infarct “remodeling” process and potentially identify and determine efficacy of novel therapeutic interventions to prevent heart failure. He is also involved in exploring novel experimental models that represent clinical manifestation of heart disease.

His lab is developing MRI tools to probe noninvasively cardiac pathophysiology parameters including viability, edema and inflammation, hemorrhage, perfusion, strain and microvascular integrity and function. Quantitative T1, T2 and T2-star MRI relaxation mechanisms form the basis for this in vivo tissue characterization, allowing for intra- and inter-subject comparisons. Another focus has been the in vivo assessment of microvascular dysfunction, including abnormal blood flow and perfusion reserve in patients with diabetes or severe infarction. This assessment is done using cardiac blood oxygenation level dependent (BOLD) imaging and arterial spin-label imaging.

His lab is also advancing image-guidance technologies for cardiac regenerative medicine. Given that the human heart lacks regenerative capacity, stem cell-based therapies are a revolutionary means to repopulate lost cells in scar tissue and regain lost contractile function. The lab aims to develop MRI-based technologies that will facilitate minimally invasive and accurate cell delivery to the infarct scar, and image cell fate, tissue response and outcomes, all within the same framework.

Well-designed preclinical studies in association with new imaging biomarkers could act as a precursor to clinical trials to interrogate emerging drug candidates and regenerative therapies for heart failure.
