NCT ID NCT06688994
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether vitamin D levels in the blood can help identify kidney injury in people who have had heart surgery. Researchers will compare vitamin D measurements with standard kidney function tests in 46 adults with different levels of kidney health. The goal is to see if vitamin D could serve as an early warning sign for kidney problems after surgery.
