Baseline triglyceride-glucose, body mass index, end-diastolic internal diameter of the left atria and creatinine are independent predictors for pulmonary hypertension in coronary artery disease patients after percutaneous coronary intervention treatments.

Aim: To identify the predictive role of triglyceride-glucose (TyG) index in pulmonary hypertension (PH) in coronary artery disease (CAD) patients after percutaneous coronary intervention (PCI) treatment.Methods: Blood biomarkers have been measured at the cross-section of entrance. The baseline and followed-up echocardiography have been performed at both cross-sections.Results: The incidence of PH was 8.91%. The baseline myoglobin (MYO), was significantly higher among PH patients (p < 0.001). In the univariate regression, body mass index (BMI p = 0.020), left atria end-diastolic internal diameter (LAD, p = 0.083), creatinine (Cr, p = 0.005), triglyceride (TG, p < 0.001), high-density lipoprotein cholesterol (HDL-C, p = 0.056) and TyG index (p = 0.002) were potential predictors for PH. Finally, the adjusted COX regression indicated that BMI (p = 0.001), LAD (p = 0.030), Cr(p = 0.005) and TyG index (p = 0.002) were independent predictors of the onset of PH.Conclusion: Baseline TyG index, BMI, LAD, Cr level were independent predictors for PH in CAD patients after PCI treatment.
