• Status: Completed
• Trial end date: 2019-01-21
• Target enrollment: 0
• Participant gender: All

Summary

Background and study aim:

Heart diseases are among the most common causes of death worldwide. A large proportion of deaths are caused by heart attacks (myocardial infarction), where blood flow to the heart is reduced resulting in damage to the heart muscle. If the arteries supplying blood to the heart start to become blocked, Coronary Artery Bypass Grafting (CABG) surgery is a treatment to replace the blocked sections of artery can reduce angina (chest pain). However, CABG surgery has complications, including an increased risk of heart attack. Vitamin D deficiency is thought to be linked to poorer recovery from heart attack and CABG surgery. This study aims to investigate if vitamin D supplementation can reduce injury to the heart following CABG surgery.

Who can participate? Adults with vitamin D deficiency undergoing CABG

What does the study involve? Participants are randomly allocated to one of two groups. Those in the first group receive vitamin D at 3 doses per day for 3 days before surgery. The second group will receive a dummy pill (placebo). Both groups will have standard CABG surgery.

What are the possible benefits and risks of participating? Those in the vitamin D group might benefit from its effects. Vitamin D has few side effects, especially when taken for only a few days.
