Study Summary

Black individuals are more likely to have decreased insulin sensitivity which results in a high risk for the development of cardiometabolic disease. The reasons for this are incompletely understood. Natriuretic peptides (NPs) are hormones produced by the heart that play a role in regulating the metabolic health of an individual. Low circulating level of NPs is an important contributor to increased risk for diabetes. The NP levels are relatively lower among Black individuals thus affecting their metabolic health and putting them at a higher risk for diabetes. This study aims to test the hypothesis that by augmenting NP levels using sacubitril/valsartan, among Black Individuals one can improve their metabolic health (as measured by insulin sensitivity \& energy expenditure) and help establish the role of NPs in the underlying mechanism behind increased risk for cardiometabolic disease in these population.

Primary Outcome

An assessment of the insulin sensitivity will be done at baseline and after 12 weeks of pharmacological intervention.
