Sex differences in hospital mortality after coronary artery bypass surgery: evidence for a higher mortality in younger women.

abstract：BACKGROUND:Among patients with documented stable coronary artery disease and in whom no revascularization was performed, we compared the respective values of angiographic diameter stenosis (DS) and fractional flow reserve (FFR) in predicting natural history. METHODS:The present analysis included the 607 patients from ...
