Dual biomarker strategy

Serial preoperative and postoperative dual biomarker measurements allowed detection of both myocardial injury and sustained cardiac stress. Serial biomarker testing was characterized as objective, readily available, inexpensive, relatively cost-effective, and less resource-intensive than more complex monitoring. The biomarker combination is useful because RCRI had limited discriminatory value in this cohort. Systematic perioperative testing with both hs-cTnI and NT-proBNP can identify higher-risk patients after elective thoracic lung resection. The dual-biomarker approach may support closer monitoring, cardiology involvement, and refined postoperative follow-up.
