Erratum to: Cardiovascular Diabetology (2015) 14:31 DOI 10.1186/s12933-015-0195-2

After publication of the original article, it came to our attention that the samples used for the MMPs and TIMP-1 measurements were serum samples instead of plasma samples. Therefore,

  1. 1.

    Plasma levels of MMPs and TIMP-1 in the title, abstract, methods, results and discussion section should read serum levels; and

  2. 2.

    In the discussion section the sentence, “Possibly the serum measurement does not truly reflect the circulating concentration of MMPs and TIMPs compared to the plasma measurement” should be disregarded.

We apologize for any inconvenience.
