Reducing kidney injury by 62%, Vitamin E is the new hero in cases of coronary angiography and percutaneous coronary interventions. Angiography allows doctors to see the inside of blood vessels, particularly the arteries. Radiopaque contrast agent is injected into blood vessel. This allows blood vessels to become more clearly visible with the proper imaging equipment. Percutaneous Coronary Intervention is a procedure where a catheter is used to insert a stent to widen blood vessels, narrowed from plaque build up.
Aside from supplementation, where else can you find substantial sources of Vitamin E?
- Wheat Germ Oil
- Turnip Greens
As always, be sure these foods are acceptable possibilities for your own unique kidney diet.
Kidney injury from these procedures is known as contrast medium induced acute kidney injury (CIAKI) and is the third most frequent cause of hospital acquired kidney injury. These injuries increase hospital stays and patient costs and make up 10% of all hospital related kidney injuries.
The causes for this kind of injury are a decrease in antioxidants and direct cytoxic effect of reactive oxygen species. Previous studies have also shown Vitamin C and N-acetylcysteine may also prevent CIAKI. The authors in the study analyzed the findings in three randomized trials of Vitamin E and found a 52%-75% better protection against CIAKI. The pooled effect showed a 62% prevention rate against CIAKI. The study was performed by Yousef Rezaei of Iran University of Medical Sciences and Harri Hemila from the University of Helsinki in Finland.
