Vitamin D Deficiency Increases Risk of Cardiovascular Disease, Finds Study

It was a cross-sectional study of 360 Saudi nationals from the tertiary care hospital. The researchers collected sociodemographic information, nutritional status, biochemical parameter (lipid profile, blood glucose level), and questions relating to cardiovascular disease through data collection sheet from hospital records. They evaluated Serum Vit D level by serum 25 (OH) blood test. They used the Binary logistic regression model to identify the associated factors of vitamin D deficiency among cardiovascular disease patients.

Key findings of the study were:

• Upon analysis, the researchers found that nearly 40.6% and 27.8% of study participants had vitamin D deficiency and insufficiency, respectively.
• After adjustment of covariates, they found that vitamin D deficiency was associated with ischemic heart disease (OR 2.24) and blood triglyceride level (OR 2.27) among cardiac patients.
• They noted that cardiac patients with abnormal Hb1c were more likely associated with vitamin D deficiency.

The authors concluded, "Vitamin D deficiency and insufficiency are associated with ischemic heart disease, hyperglycemia, and hypertriglyceridemia. The finding of this study suggested that risk factors of vitamin D among cardiac patients should be monitored to prevent the consequences of CVD. Health promotion should be developed to increase awareness among the general population, specifically heart disease patients regarding vitamin D deficiency."
