Minimally invasive coronary artery bypass grafting: dual-center experience in 450 consecutive patients.

abstract：BACKGROUND:Chronic Chlamydia pneumoniae and Helicobacter pylori infections could be a risk factor for ischemic heart disease (IHD), possibly by increasing fibrinogen levels. The aim of our study was to evaluate changes in fibrinogen level in patients with IHD and H pylori and/or C pneumoniae positivity randomly assigne...
