Impact of 25(OH)D3 on spontaneous reperfusion and SYNTAX score in patients with ST-elevation myocardial infarction

Objective: The aim of this study was to evaluate the potential relationship between 25-hydroxyvitamin D3 (25[OH]D3), the Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) score, and spontaneous reperfusion (SR) in patients with ST-elevation myocardial infarction (STEMI). Methods: A total of 148 consecutive patients with acute STEMI who underwent primary percutaneous coronary intervention were retrospectively enrolled in the study. Results: In all, 36 patients with a TIMI 3 flow score (spontaneous reperfusion [SR]) before coronary intervention constituted Group 1, and 112 patients with a TIMI flow score of 0-2 served as Group 2. The SYNTAX score and the in-hospital major adverse cardiovascular event (MACE) rate were significantly higher in Group 2 (p
