Vitamin D Deficiency Associated with Poorer Outcomes after Cardic Arrest

Research presented at the 2014 annual meeting of the  European Society of Cardiology  in Geneva, Switzerland,  showed that patients who were Vitamin D deficient were much more likely to have a bad neurological outcome after sudden cardiac arrest than those who were not deficient. Vitamin D deficiency also led to a higher chance of dying as a result of the cardiac arrest.

The researchers analyzed clinical data from 53 consecutive patients resuscitated from  sudden cardiac arrest and brought to the Severance Cardiovascular Hospital in Seoul, South Korea.   Nearly one-third of the patients who were deficient in vitamin D had died within the 6 months after their cardiac arrest, whereas all patients with sufficient vitamin D levels were still alive. In this study the neurologic functioning of surviving patients  was  evaluated at 6 months after  hospital discharge. Vitamin D deficient patients  had more significant impairment of their cognitive / neurologic functioning  compared to those who were not vitamin D deficient.

Lead researcher Dr Jin Wi says: “In patients resuscitated after sudden cardiac arrest, recovery of neurological function is very important, as well as survival. Vitamin D deficiency has been reported to be related to the risk of having various cardiovascular diseases, including sudden cardiac arrest. We investigated the association of vitamin D deficiency with neurologic outcome after sudden cardiac arrest, a topic on which there is no information so far.”

He continued, “A large randomized clinical trial is needed to find out whether supplements of vitamin D can protect high risk groups from having a sudden cardiac arrest.”

Vitamin D is made when the skin is exposed to sunlight. Foods with high content of Vitamin D are oily fish such as salmon and sardines, eggs, and fortified cereals.
