Introduction:

The glycemia-triglyceride index is used for the presumptive diagnosis of insulin resistance, which in hypertensive patients is related to the severity of high blood pressure.

Objective:

To determine the utility of the glycemia-triglyceride index as a marker of insulin resistance in adult patients diagnosed with essential arterial hypertension.

Methods:

A descriptive cross-sectional study was carried out in 232 patients diagnosed with essential arterial hypertension. The glycemia-triglyceride index was calculated and compared with HOMA index. For this analysis, ROC curve, Pearson correlation and Kappa index were used, p value less than 0.05 was considered significant.

Results:

We obtained an 8.1 cut-off point, showing 98.6 sensitivity and 41.4 specificity. The area below the ROC curve showed 0.694 ≈ 0.7 value. Positive correlation was observed (p = 0.008). Kappa index = 88.4%.

Conclusions:

The glycemia-triglyceride index turned out to be useful in patients with essential hypertension as a marker of insulin resistance with a cut-off point of 8.1.
