In the heart attack research, his group seeks to better understand the nature of heart muscle injury, including causes, consequences, and health outcomes in the longer term. His research described the natural history of heart muscle bleeding after a heart attack. The research uses novel medical technologies such as diagnostic guidewires that can measure blood pressure and resistance inside blood vessels within the heart, and heart imaging with MRI. Current and future studies are aimed to identify new treatments, such as in the T-TIME study, which may help patients who have had a heart attack. His group are also working with mathematicians and statisticians to develop ‘patient-specific’ computed heart models from heart scans in order to better predict clinical outcome and response to treatment.
