Vitamin D deficiency and periprocedural myocardial infarction in patients undergoing percutaneous coronary interventions

Abstract Vitamin D deficiency has been implicated in the progression of atherosclerosis and acute thrombotic events. We aimed at evaluating the impact of vitamin D deficiency on periprocedural myocardial infarction (PMI) in patients undergoing percutaneous coronary interventions (PCI). We included 934 patients undergoing non-urgent PCI. Assessment of myocardial biomarkers was performed from 6 to 48 h after PCI. PMI was defined as Creatine Kinase-MB increase by 3 times the Upper Limit Normal or by 50% of an elevated baseline value, periprocedural myocardial damage as Troponin I increase by 3 × ULN or 50% of baseline. Patients were divided according to vitamin D tertiles values ( Therefore, in patients undergoing PCI, no association was observed between vitamin D deficiency and the risk of periprocedural MI and myocardial damage.
