AbstractVitamin D deficiency is associated with acute coronary syndrome (ACS). We aimed to evaluate calcidiol status and its relationship with coronary angiography findings in two selected groups of ACS patients.We investigated two groups of patients with ACS: 75 patients with ST-segment-elevation myocardial infarction (STEMI) and 68 patients with unstable angina pectoris (USAP). The ACS diagnosis was confirmed by coronary angiography findings. Biochemical parameters were studied at the first visit of the patients with automated instruments and ready-to-use kits.Calcidiol levels were significantly lower in the STEMI group compared to the USAP group (p<0.001), while the prevalence of calcidiol deficiency in the STEMI group was significantly higher (p<0.001). Serious calcidiol deficiency (<4 ng/mL) was present in 17% of the STEMI group and in 7% of the USAP group. We did not observe any significant relationship between calcidiol status and coronary angiography findings.Our results support the previously described associations between ACS and calcidiol deficiency. Besides, we report a more severe calcidiol deficiency and an extraordinarily high prevalence of vitamin D deficiency or insufficiency in these patients.
