Genotype-guided approach to improve cardiometabolic health using natriuretic peptides

Atrial Natriuretic Peptide and Regulation of Cardiometabolic Health: A Genotype-Guided Human Physiological Study

Not applicable Interventional University of Alabama at Birmingham · NCT05216042

This study is testing if a special approach using natriuretic peptides can help improve heart and metabolic health in adults with a certain genetic variant that leads to lower levels of these peptides.

What this trial studies

This study investigates the role of natriuretic peptides (NPs) in regulating cardiometabolic health, particularly in individuals with genetically lower NP levels. It focuses on understanding how exercise and glucose challenges affect NP responses in adults who carry a specific genetic variant associated with lower NP levels. The study aims to explore the metabolic benefits of NPs and their potential to mitigate risks associated with cardiovascular diseases and diabetes. Participants will undergo dietary assessments, exercise capacity evaluations, and challenges to assess their metabolic responses.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who consent to genetic material collection and are willing to adhere to the study protocol.

Not a fit: Patients with a history of cardiovascular diseases, diabetes, or those with severe obesity (BMI > 45 kg/m2) may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved strategies for managing cardiometabolic health in individuals with low natriuretic peptide levels.

How similar studies have performed: Previous studies have indicated the importance of natriuretic peptides in metabolic health, suggesting that this approach may yield beneficial insights, although the specific genetic focus is relatively novel.
