Is elevated triglyceride/high-density lipoprotein cholesterol ratio associated with poor prognosis of coronary heart disease? A meta-analysis of prospective studies

Medicine (Baltimore). 2022 Nov 11;101(45):e31123. doi: 10.1097/MD.0000000000031123.

Abstract

Background: Elevated triglycerides (TG) and reduced high-density lipoprotein cholesterol (HDL-C) are recognized as essential and independent hazard factors for total death and major adverse cardiovascular events (MACE) in patients with coronary heart disease (CHD). However, whether the increased TG/HDL-C forecasted the prognosis of CHD is still unknown. Therefore, we performed a meta-analysis to investigate the relationship between the elevated TG/HDL-C ratio and poor prognosis of CHD.

Methods: A systematic literature search was conducted in PubMed, Web of Science, EMBASE, and The Cochrane Library, until August 30, 2021. Prospective observational studies regarding the association between TG/HDL-C and long-term mortality/MACEs in CHD patients were included.

Results: In total, 6 independent prospective studies of 10,222 participants with CHD were enrolled in the systematic and meta-analysis. Our outcomes of the meta-analysis indicated that the elevated TG/HDL-C group had a significantly increased risk of long-term all-cause mortality (hazard ratio [HR] = 2.92, 95% confidence interval [CI]: 1.75-4.86, P < .05) and long-term MACEs (HR = 1.56, 95%CI 1.11-2.18, P < .05).

Conclusion: In patients with CHD, the present study showed that the high TG/HDL-C was associated with increased risk of long-term all-cause mortality and MACE.
