Table 2 Hemodynamic in patients with and without post-CPB left ventricular dysfunction

From: Preoperative diastolic function predicts the onset of left ventricular dysfunction following aortic valve replacement in high-risk patients with aortic stenosis

  1. LV, left ventricular; CPB, cardiopulmonary bypass.
  2. *P < 0.05, between the two groups; χ2 test with Yates correction or unpaired Student t test.
