Cardioprotective effects of remimazolam in elderly hypertensive patients undergoing gastrointestinal tumor surgery: A randomized controlled trial

Figure 1 Comparison of trends in perioperative serum biomarkers of myocardial injury between the two groups. A: High-Sensitivity Troponin; B: Creatine kinase; C: Creatine kinase-MB; D: Lactate dehydrogenase; E: AST; F: NT-proBNP. hs-cTn: High-Sensitivity Troponin; CK: Creatine kinase; CK-MB: Creatine kinase-MB; LDH: Lactate dehydrogenase; AST: Aspartate aminotransferase; NT-proBNP: N-terminal pro-brain natriuretic peptide.

Figure 2 Comparison of trends in arterial blood gas parameters between the two groups. A: Systolic blood pressure; B: Diastolic blood pressure; C: Heart rate; D: Glucose; E: Lactate; F: Partial pressure of carbon dioxide. SBP: Systolic blood pressure; DBP: Diastolic blood pressure; HR: Heart rate; Glu: Glucose; Lac: Lactate; PaCO₂: Partial pressure of carbon dioxide.

Figure 3 Comparison of trends in postoperative Visual Analog Scale scores between the two groups. VAS: Visual Analog Scale.

Figure 4 Receiver operating characteristic curve of the myocardial injury after non-cardiac surgery prediction model in elderly hypertensive patients after gastrointestinal tumor surgery. NT-proBNP: N-terminal pro-brain natriuretic peptide; MINS: Myocardial injury after non-cardiac surgery.
