BACKGROUND: There is growing epidemiological evidence linking serum 25 hydroxy-vitamin D (25(OH)D) concentrations to outcome in cardiovascular and other diseases. We have studied patients with acute myocardial infarction (AMI) to determine if they exhibit an acute phase reaction affecting 25(OH)D.

METHODS: Patients (n=32) with first AMI who had been treated with primary percutaneous coronary intervention within 12 h of symptom onset had venous blood samples taken two days, one week, one month and three months after presentation. Samples were analysed for troponin I, C-reactive protein (CRP) and 25(OH)D.

RESULTS: All patients had significant rises in troponin confirming the myocardial damage and CRP, both of which resolved by 28 days.
In contrast, 25(OH)D remained unchanged throughout the 90-day observation period with a median concentration of 46 nmol/L.

CONCLUSION: Serum 25(OH)D does not change after AMI and is likely to be a reliable marker of vitamin D status in patients with cardiovascular disease.

Strange - most stress/traumas reduce levels of vitamin D
