Correction to: BMC Cardiovasc Disord (2020) 20:457, https://doi.org/10.1186/s12872-020-01739-z

Following publication of the original article [1], the author identified two errors in the article body.

  1. 1

    "selenium group" should be replaced with "controls" in Fig. 1.

  2. 2

    "consent" should be replaced with "concept" in the first sentence of the Discussion section.

The original article [1] has been corrected.
