Brief Summary:
Hypertrophic Cardiomyopathy (HCM) is the most common inherited heart condition, where the heart muscles can thicken to the point of obstructing blood flow out of the heart. This condition is associated with a chronic state of energy loss in the heart muscle.
Till more recently, a new class of medication (cardiac myosin inhibitors) have been introduced to directly target the heart muscle proteins (sarcomeres) to reduce the strength of contraction and relieve obstruction of blood flow out of the heart. While clinical trials have shown this class of medication significantly improves physical capacity and patient symptoms, it is still unclear, based on small scale published studies, where this improvement is achieved by restoring the fundamental energy balance within the heart.
Our research study aims to answer this question and prove mechanistic insights of the use of this class of medication in the HCM population with blood flow obstruction (otherwise known as obstructive HCM) by using a specialised non-invasive MRI technique which accurately measures the heart energy score (specifically known as the PCr/ATP ratio) in each participant. Our objective is to determine how a patient with obstructive HCM have their energy scores affected, and improve over time with this medication therapy. If positive, this finding could establish the use of PCr/ATP ratio as a crucial, objective biomarker for monitoring therapeutic response and informing personalised dosing strategies for patient in the future.
