Correlation of Triglyceride with Coronary Artery Disease Severity in Pre-Diabetic Chronic Stable Angina Patients

Background: Individuals with prediabetes have multiple disturbances in lipoprotein metabolism resulting from multiple combinations of insulin deficiency, insulin resistance and hyperglycemia. Dyslipidemia is the commonest complication of prediabetes and diabetes, and it predispose to premature atherosclerosis causing cardiovascular complication. The aim of this study was to assess correlation of triglyceride (TG) with coronary artery disease (CAD) severity in pre-diabetic chronic stable angina patients.

Methods: Our cross-sectional observational study was conducted on 100 pre-diabetic patients (HbA1c 5.7% to 6.4%) with different levels of TG and stable CAD, referred to Tanta university hospitals. Each patient had been subjected to adequate history taking, complete clinical examination and laboratory investigations and electrocardiogram with transthoracic echocardiography. SYNTAX score was calculated.

Results: There were significant positive correlations between TG and LDL, ratio and TLC respectively while there was a significant negative correlation between TG and HDL. There was significant positive correlation between SYNTAX and LDL, ratio and urea respectively while there was high significant negative correlation between TG and HDL. TG level was significantly higher in male than female (p= 0.028). There was no significant difference in SYNTAX regarding gender. For the multivariate analysis, only LDL was a significant independent predictor for CAD.

Conclusions: There was a positive correlation between the TG and the severity of coronary lesions in pre-diabetic stable angina pectoris patients.
