Latent tuberculosis infection among patients with coronary artery stenosis: A case-Control study.

Background: The activation of the cell-mediated immune responses by Mycobacterium tuberculosis can promote atherogenesis.

Aims: The aim of this study is to determine the frequency of latent tuberculosis infection (LTBI) among patients with coronary artery stenosis (CAS) and to explore the association between LTBI and development of CAS. We conducted a case-control study which included 183 patients' who underwent percutaneous coronary angiography (121 patients with CAS and 62 patients without as a control group).
