NPPB and pericardial effusion: Compared to those with CA 125 ≤ 35 U/ml, patients with CA 125 > 35 U/ml had lower mixed venous oxygen saturation (SVO2), lower cardiac index (CI) values, a larger right ventricular end-diastolic diameter (RVED), higher prevalence rates of hyperlipidaemia and pericardial effusion, higher mean right atrial pressure (mRAP), and higher serum levels of NT-proBNP and CA 125 [55.9 (43.7, 83.0) vs. 14.5 (10.6, 21.1) U/ml, P < 0.001].
