CHANGES IN THE LEVEL OF NT-proBNP AND MEAN PULMONARY ARTERY PRESSURE FOLLOWING BRONCHOPLASTIC LOBECTOMY OR PNEUMONECTOMY AS MARKERS OF RIGHT VENTRICULAR DYSFUNCTION

Background There are scanty data of right ventricular dysfunction markers after major pulmonary resection. Objective To study the changes plasma level N-terminal pro-brain natriuretic peptide (NT-proBNP) and its association with artery pressure (PAP) as in patients who underwent bronchoplastic lobectomy or pneumonectomy. Material Methods The population consisted 36 aged 40–65 resection for lung cancer 2016–2018. Patients were stratified into two groups according to type surgical procedure: lobectomy, main group (n = 19), pneumonectomy, control 17). They then analyzed NT-proBNP concentration, operative time, blood loss, intraoperative fluid administration, urine output, mean PAP before an operation. Results correlated positively concentration pneumonectomy (Pearson r 0.916754; p < 0.001). This correlation was no evident subset undergoing at same determination point 0.234741; 0.330). Conclusion increased significantly is closely NTproBNP concentration. These findings support conclusion that bronchoplasty preferable over patients.
