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.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.
