Project Title

British Columbia Prospective Cohort of Hypertrophic Cardiomyopathy Patients (HiRO-HCM)

Project Description

This recruitment is ongoing as part of our collaboration with the Hearts in Rhythm Organization (HiRO) Hypertrophic cardiomyopathy (HCM) is a common form of heart disease, affecting 1 in 200 people. In HCM, the heart muscle thickens, and over time this can lead to other health problems, from shortness of breath to sudden death. There are limited tools to help identify people who are at risk of poor outcomes related to their disease, or to monitor or predict the rate of disease progression. Imaging, using MRI, is currently the best tool to diagnose HCM and to help guide decision-making by the clinical care team. Frequent follow-up MRIs would be helpful, but are neither feasible nor would give a complete picture of disease progression. We plan to develop a blood test that can identify people at risk of heart failure, and to monitor HCM disease progression. To develop this blood test, we will first understand differences between HCM hearts and normal hearts using many tools, from pictures of the entire heart muscle all the way down to single heart muscle cells. We will analyze all available imaging and clinical data from HCM patients. We will also study heart muscle tissue that has been removed from patients who underwent surgery to relieve obstruction caused by their thickening heart muscle. We will study this heart muscle using a new single-cell technology that we helped to develop. We will also analyze the blood of these patients, to find protein markers related to HCM disease progression. Our ultimate goal is to give patients and their caregivers an effective test which provides unique insights into their heart disease, and has the potential to change management. This will become increasingly important in the coming years as new therapies are tested for HCM that hold the hope and promise of halting or reversing disease progression in HCM.
