Prognostic relevance of ventricular arrhythmias in surgical patients with gastrointestinal tumors

Figure 1 Study flow, including patient enrollment and outcomes. hs-cTnI: High-sensitivity cardiac troponin I; LVEF: Left ventricular ejection fraction; MACE: Major adverse cardiovascular event.

Figure 2 Receiver operating characteristic curves of premature ventricular contractions for combined endpoints. A: Receiver operating characteristic curve of premature ventricular contractions (PVCs) for all-cause mortality among patients with gastrointestinal tumors; B: Receiver operating characteristic curve of PVCs for major adverse cardiovascular events among patients with gastrointestinal tumors. PVC: Premature ventricular contraction; AUC: Area under the curve.

Figure 3 Cumulative survival of all patients. A: Cumulative survival of all-cause mortality among patients with gastrointestinal tumors divided by premature ventricular contractions (PVCs) (n = 130); B: Cumulative survival of major adverse cardiovascular events (MACEs) among patients with gastrointestinal tumors divided by PVCs (n = 130); C: Cumulative survival of all-cause mortality among patients with gastrointestinal tumors divided by non-sustained ventricular tachycardia (n = 130); D: Cumulative survival of MACEs among patients with gastrointestinal tumors divided by non-sustained ventricular tachycardia (n = 130). PVC: Premature ventricular contraction; MACE: Major adverse cardiovascular event; NSVT: Non-sustained ventricular tachycardia.
