coronary artery disease, vitamin D deficiency, Hs-CRP

Large population cross sectional study, was conducted between 2018-2020 by attendance of 4526 patients in shiraz, Iran. Patients were undergone selective coronary angiography from radial artery approach by an expert interventional cardiologist. 25-hydroxy vitamin D and Hs-CRP levels were measured for all patients

This cross-sectional study was conducted in Shiraz. Clinical data were collected from the patients of Professor Kojuri cardiovascular clinic in Shiraz, Iran ( Iran, Fars Province, Shiraz, Niayesh Boulevard, Email: kojurij@yahoo.com, webpage: http://kojuriclinic.com/ )who came to clinic from March 2018 to March 2020.

Patients with more than 10mg/L Hs-CRP serum level also were excluded. Complete history and physical exam were taken from the patients and risk factors such as hypertension, diabetes mellitus, age and gender were considered. 25-hydroxy vitamin D3 was checked for all patients. Blood pressure and took electrocardiography (ECG) for all patients were done.
