Aim: Triglyceride to high density lipoprotein cholesterol (TG/HDL-C) ratio and triglyceride-glucose (TyG) index are simple, reliable screening methods. It has been shown that the TyG index predicts mortality in cardiovascular diseases and the TG/HDL-C ratio predicts the severity of coronary artery disease (CAD). We planned a study to define the relationship between the SYNTAX score, which indicates the severity of CAD, and the TyG index and TG / HDL-C ratio. Material and Methods: A total of 408 patients who underwent coronary angiography were evaluated in this study. TyG index, TG/HDL-C ratio and SYNTAX scores were calculated. Patients were grouped according to their diagnosis and SYNTAX scores. Relationships between TyG index, TG / HDL-C ratio and SYNTAX score were examined. Results: There is a significant relationship between the TyG index and the presence of CAD (p<0.001). When the TyG index was evaluated in terms of the severity of CAD, there was a positive significant relationship between mild and severe CAD (p<0.040). While there was a significant positive correlation between TG/HDL-C ratio and the presence of CAD (p<0.001), there was no significant relationship between severity of CAD (p:0.814). There was a low level significant positive correlation in terms of TyG index between patients with unstable angina pectoris and ST-elevation myocardial infarction (p:0.046). Conclusion: The TyG index and TG/HDL-C ratio are predictors of the presence of CAD and the TyG index also provides guidance on the severity of CAD. Standard use may be considered in addition to risk scoring in the diagnosis of CAD and planning coronary angiography.
