title: Vitamin D level and extent of coronary stenotic lesions in patients with first acute myocardial infarction.
abstract: BACKGROUND
  The study aimed to examine the relationship between vitamin D levels and the extent of coronary stenotic lesions in patients with ST-segment elevation myocardial infarction (STEMI). Experimental evidence points to the involvement of multiple factors in coronary plaque formation, including vitamin D. Little is known, however, about the association of vitamin D level with the intensity of atherosclerosis.
  
  
  METHODS
  Serum concentrations of 25-hydroxyvitamin D [25(OH)D] were measured in 130 consecutive patients with the first acute STEMI treated with primary percutaneous coronary intervention. STEMI was the first symptom of coronary artery disease (CAD). The study population was divided into patients with single and multi-vessel CAD. The angiographic severityof CAD was also determined based on the Gensini score.
  
  
  RESULTS
  The median 25(OH)D concentration was 11.12 ng/mL (25th and 75th percentile: 6.05; 17.12). Insufficient (20-30 ng/mL), deficient (10-20 ng/mL) and severely deficient(< 10 ng/mL) 25(OH)D levels were present in 18%, 35% and 45% of the individuals, respectively. Only 2 (2%) of patients had proper 25(OH)D levels (> 30 ng/mL). The 25(OH)D concentrations between patients with single- and multi-vessel CAD did not differ significantly (10.2 vs. 11.4 ng/mL, p = 0.62). There was no significant correlation between 25(OH)D levels and Gensini score (r = -0.0221, p = 0.81).
  
  
  CONCLUSIONS
  The study demonstrated that vitamin D level is not associated with the severity of coronary lesions in patients with the first STEMI. A high prevalence of vitamin D deﬁciency in these patients was confirmed.
