Evaluation of Serum Vitamin D Level as a Prognostic Marker in the Clinical Manifestation of Acute Coronary Syndrome Patients

Introduction: Epidemiologic studies have shown a strong association between Vitamin D deficiency and cardiovascular risk factors, myocardial infarction, and all-cause cardiovascular mortality. The purpose of this study was to determine the clinical implications of serum Vitamin D levels in an unselected cohort of acute coronary syndrome (ACS) patients at the time of hospital admission. Methods: This was a prospective observational study which enrolled a total of 310 patients from December 2015 to March 2018. The consecutive in-hospital patients with ACS diagnosed by the typical history of angina, electrocardiography changes, with or without cardiac enzymes were included in the study. The primary endpoint of the study was all-cause death during hospitalization. The secondary endpoint was the in-hospital incidence of major adverse cardiac events (MACEs). Results: The number of patients with diabetes and dyslipidemia was significantly higher in the Vitamin D-deficient group (46.7%, P = 0.04 and 45.4%, P =
