The association between the serum level of vitamin D and ischemic heart disease: a study from Jordan

Area of Science:

• Cardiology
• Endocrinology
• Nutritional Science

Background:

• Vitamin D deficiency is linked to increased cardiovascular disease risk, but study results vary.
• The role of sufficient serum vitamin D in preventing coronary artery stenosis and ischemic heart disease (IHD) requires further investigation.

Purpose of the Study:

• To investigate the association between serum vitamin D levels and the incidence and progression of coronary artery stenosis and IHD.
• To explore the relationship between vitamin D status and various cardiovascular risk factors in a Jordanian population.

Main Methods:

• Serum vitamin D levels were measured via radioimmunoassay in 186 Jordanian patients undergoing coronary catheterization.
• 133 patients had diagnosed coronary artery stenosis.
• Statistical analysis using SPSS software examined associations between vitamin D levels, stenosis, and risk factors.

Main Results:

• No significant association was found between vitamin D abnormalities and the incidence or reoccurrence of coronary artery stenosis.
• Vitamin D abnormalities showed significant differences based on patient gender.
• A significant association existed between vitamin D abnormalities, body mass index, and dyslipidemia.

Conclusions:

• Serum vitamin D levels do not appear to be directly associated with coronary artery stenosis incidence or progression in this cohort.
• Gender, body mass index, and dyslipidemia are associated with vitamin D abnormalities.
• No significant association was found between vitamin D status and other major IHD risk factors like smoking, hypertension, or diabetes.
