Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
All phenotype positive patients will undergo a 10ml genetic blood test. Patients who are then genotype positive for cardiac myosin binding protein-C mutations or cardiac beta-myosin heavy chain gene mutations will be recruited and undergo baseline cardiac magnetic resonance imaging, cardiac magnetic resonance spectroscopy and echocardiography. These will be repeated at 1, 2 and 4 years.

Outcomes
Primary outcome [1] 266706 0
Phosphocreatine (PCr)/Adenosinetriphosphate (ATP) ratio. Method: Cardiac magnetic resonance spectroscopy will be used to measure cardiac high energy phosphate metabolism in-vivo. The novel SLOOP method (spatial localisation with optimum pointspread function) allows accurate measurement of absolute concentrations of high-energy phosphates.
