Vitamin D deficiency linked to poor brain function after cardiac arrest

A new study has revealed that Vitamin D deficiency increases the risk of poor brain function after sudden cardiac arrest by seven-fold. According to lead researcher Jin Wi from Korea, in patients resuscitated after sudden cardiac arrest, recovery of neurological function is very important, as well as survival and Vitamin D deficiency has been reported to be related to the risk of having various cardiovascular diseases, including sudden cardiac arrest. The researcher said that they investigated the association of vitamin D deficiency with neurologic outcome after sudden cardiac arrest, a topic on which there is no information so far.

Patients with a poor neurological outcome had a significantly lower vitamin D level compared to those with a good neurological outcome. The researchers found that 65 percent of patients with vitamin D deficiency had a poor neurological outcome at 6 months after discharge compared to 23 percent of patients with healthy vitamin D levels. They also found that 29 percent of patients with vitamin D deficiency had died at 6 months compared to none of the patients with good vitamin D levels.

Wi said that patients with vitamin D deficiency were more likely to have a poor neurological outcome or die after sudden cardiac arrest than those who were not deficient. Nearly one-third of the patients who were deficient in vitamin D had died 6 months after their cardiac arrest, whereas all patients with sufficient vitamin D levels were still alive. Vitamin D deficiency increased the risk of poor neurological outcome after sudden cardiac arrest by 7-fold. The only factors that had a greater impact on poor neurological outcome were the absence of bystander CPR or having a first monitored heart rhythm that was non-shockable. (Read: )

The researchers added that their findings suggest that vitamin D deficiency should be avoided, especially in people with a high risk of sudden cardiac arrest. People are at higher risk if they have a personal or family history of heart disease including heart rhythm disorders, congenital heart defects and cardiac arrest. Other risk factors for cardiac arrest include smoking, obesity, diabetes, a sedentary lifestyle, high blood pressure and high cholesterol, and drinking too much alcohol.

Here are top 12 health risks you might be facing due to low levels of vitamin D.

1. Diabetes: The number of diabetic people is increasing day by day and most of them might be deficient in vitamin D. Vitamin D is required to balance sugar levels in the blood by regulating the secretion of insulin. Research suggests that low levels of vitamin D increases the risk of developing type 2 diabetes later in life. Some studies have also found that the vitamin D also increases the risk of type 1 diabetes.

2. Hypertension: Indian research based on a large scale observational data showed that people having low levels of 25-hydroxyvitamin D (a form of vitamin D) had a higher risk of developing hypertension; however, the correlation is not yet found.

3. Cardiovascular risk: A population-based study of 9,949 adults showed that vitamin D deficiency is significantly associated with increased risk of fatal cardiovascular events. The study considered adjustments for smoking, physical activity and other factors contributing to heart diseases and concluded that vitamin D deficiency increased the risk of fatal cardiovascular diseases (CVD) by 62%.
