Central-Radial Artery Pressure Gradient after Cardiopulmonary Bypass Is Associated with Cardiac Function and May Affect Therapeutic Direction

To investigate the risk factors involved in radial-femoral artery pressure gradient after cardiac surgery.In this retrospective study, we reviewed 412 cardiac surgeries with both femoral artery pressure and radial artery pressure monitoring before cardiopulmonary bypass. 138 patients had radial-femoral artery pressure gradient after cardiopulmonary bypass (group P) but 263 were not (group N). Their hemodynamic data and other demographic data were analyzed. in group N at baseline, after discontinuation of CPB, at the end of surgery and the first postoperative day (P
