Vitamin d levels after heart attack: a simple fix for major risks?
NCT ID NCT02996721
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether getting vitamin D levels above 40 ng/mL after a heart attack could reduce the chance of death, another heart attack, stroke, or heart failure hospitalization. About 634 heart attack patients were split into two groups: one got standard care, and the other got extra vitamin D3 to raise their levels. The goal was to see if normalizing vitamin D makes a real difference in preventing major heart-related events.
