What the study is about

This research study wants to learn about Chronic Kidney Disease (CKD) with Obesity, and Heart Failure with preserved Ejection Fraction (HFpEF) and better ways to evaluate these diseases. HFpEF means that the heart is not able to fill properly with blood while it is resting so the amount of blood pumped out to the body is less than it would be if it was filling properly. The study is being done to describe the differences in how the kidneys handle protein and salt in participants with HFpEF and obesity compared to healthy persons.

Being studied: High protein and sodium meal

Conditions: Chronic Kidney Disease; Heart Failure With Preserved Ejection Fraction (HFPEF); Obesity (Disorder)
