Chronic Total Occlusion and Triglyceride-Glucose Index
An observational study of CAD - Coronary Artery Disease and Chronic Total Occlusion (CTO), run by Kırıkkale University at 1 site in Turkey (Türkiye).
Trial summary
We retrospectively analyzed 200 CAD patients undergoing coronary angiography between 2026-2027. Patients were grouped by CTO presence. Clinical and laboratory parameters were compared, and logistic regression was performed to identify independent predictors. Read more about this study

About this study
Official title: The Role of the Triglyceride-Glucose Index in Determining the Risk of Chronic Total Occlusion in Coronary Artery Disease
We retrospectively analyzed 200 CAD patients undergoing coronary angiography between 2026-2027. Patients were grouped by CTO presence. Clinical and laboratory parameters were compared, and logistic regression was performed to identify independent predictors.
- Being tested
- triglyceride-glucose (TyG) index was calculated from routinely obtained blood samples using the formula: Triglyceride (mg/dL) × Glucose (mg/dL) / 2.
- Medical subject headings
- Coronary Artery Disease
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
triglyceride-glucose (TyG) index was calculated from routinely obtained blood samples using the formula: Triglyceride (mg/dL) × Glucose (mg/dL) / 2.Diagnostic test
As no previous studies have demonstrated the predictive value of the TyG index for chronic total occlusion (CTO), the present investigation provides a novel contribution to the literature. We hypothesize that the triglyceride-glucose (TyG) index will be significantly higher in patients with chronic total occlusion (CTO) compared to those without CTO.
| Study group | Role | What they receive |
|---|---|---|
| Non CTO | CTO (chronic total occlusion) Receives: Diagnostic Test: triglyceride-glucose (TyG) index was calculated from routinely obtained blood samples using the formula: Triglyceride (mg/dL) × Glucose (mg/dL) / 2. | |
| CTO | CTO (chronic total occlusion) Receives: Diagnostic Test: triglyceride-glucose (TyG) index was calculated from routinely obtained blood samples using the formula: Triglyceride (mg/dL) × Glucose (mg/dL) / 2. |
What is being measured
The primary outcome is the main question the study is designed to answer.
The primary outcome measure will be the difference in the triglyceride-glucose (TyG) index between patients with chronic total occlusion (CTO) and those without CTO, assessed from routinely obtained blood samples.
Measured: 1 Year

Questions about this trial
What is this clinical trial studying?

What does the primary outcome measure?
The primary outcome measure will be the difference in the triglyceride-glucose (TyG) index between patients with chronic total occlusion (CTO) and those without CTO, assessed from routinely obtained blood samples. (time frame: 1 Year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
