Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults aged 19 to 75 with hypertension, hypertrophic cardiomyopathy, or stable heart failure.
✕Probably not a fit
Patients with contraindications to MRI, severe anemia, or life expectancy of less than one year may not benefit from this study.

What this trial studies
This study investigates a novel imaging technique using hyperpolarized carbon-13 pyruvate injection to assess heart metabolism in individuals with hypertension and hypertrophy. Participants will undergo MRI scans after receiving a glucose drink to optimize imaging results. The goal is to gain insights into heart failure treatments by visualizing biochemical reactions in the heart, potentially leading to earlier interventions and improved patient outcomes. The study will compare different labeling patterns of the pyruvate to gather comprehensive metabolic data.
Why it matters
Potential benefit: If successful, this approach could lead to earlier treatment options for heart failure, reducing morbidity and mortality rates associated with the condition.
How similar studies have gone: While this imaging method is novel, similar approaches using advanced MRI techniques have shown promise in other studies.
