ABSTRACT
OBJECTIVE:
The aim of this study was to explore the relationship between preoperative right ventricular (RV) function and high vasoactive-inotropic score (VIS) after cardiac surgery.DESIGN:
Prospective observational study.SETTING:
A single medical center setting.PARTICIPANTS:
One hundred three patients undergoing elective cardiac surgery.INTERVENTIONS:
None. MEASUREMENTS AND MAINRESULTS:
Consecutive patients referred for cardiac surgery were enrolled prospectively. Comprehensive transesophageal echocardiography was performed before sternal incision. Specific RV indices, encompassing RV fractional area change, tricuspid annular plane systolic excursion, and RV global longitudinal strain (RVGLS), were measured offline. High VIS was defined as a maximum VIS of ≥20 in 24 hours postoperatively. Postoperative adverse events were recorded. One hundred three patients (mean age 61.2 ± 11.0, 72 men) were included in this study, where 17 patients (16.5%) achieved high VIS with a mean maximum VIS of 39 in 24 hours postoperatively. Patients with high VIS encountered increased occurrence of extracorporeal membrane oxygenation placement, acute kidney injury, and mortality. Risk factors for high VIS included operation type, cardiopulmonary bypass duration, left atrium size, and pre-incisional RV indices. After adjustment for age, left ventricular ejection fraction, and the covariates, only RVGLS (odds ratio 1.19, pâ¯=â¯0.011) showed an independent association with high VIS. The optimal cutoff of RVGLS was -16.7% (sensitivity of 88.2%, specificity of 75.6%).CONCLUSION:
Preoperative RV dysfunction is an independent risk factor for postoperative high VIS. Pre-incisional RVGLS is a reliable tool to predict high VIS after cardiac surgery. Patients with high VIS had increased adverse events postoperatively.Palavras-chave
