Open Heart Surgery associated with low vitamin D, but not if 150,000 IU before surgery – RCT
Stress of open-heart surgery significantly reduces vitamin D levels, but supplementation helps
Presented at American College of Cardiology Scientific Session in Orlando on March 12
RCT = ASSESS-D,
150 RCT patients, half got three daily 50,000-unit doses of vitamin D3 (150,000 IU total)
Dr. Muhlestein
open-heart surgery patients generally have low levels of vitamin D to begin with, and
stress associated with the surgery further reduced their vitamin D levels by the time they were discharged from the hospital.
