Objective
Pulmonary hypertension is a negative prognostic indicator in patients undergoing cardiac surgery. Preoperative assessment of such patients demands clinical, echocardiographic and hemodynamic exams. Our study aims to identify the most powerful predictors of complications after cardiac surgery in patients with pulmonary hypertension.
Methods
We included 159 patients with preoperative pulmonary hypertension due to left heart diseases who underwent cardiac surgery. The echocardiographic examination included: left ventricle ejection fraction (LVEF), systolic pulmonary artery pressure (sPAP); right atrium area indexed to the body surface; TAPSE; presence of pericardial fluid. Right heart catheterization data included: mean pulmonary artery pressure (mPAP), cardiac index (CI), right atrium pressure (RAP), pulmonary vascular resistance (PVR). We analyzed a composite end point which included death; pericardial, hepatic, renal complications; postoperative mechanical ventilation> 24 hours; need for pulmonary vasodilator drugs.
