Abstract
Background
s: Cholesteryl ester transfer protein (CETP) inhibition has long been attracting a lot of attention if it could reduce the risk for coronary artery disease (CAD). A previous study has demonstrated that protein-truncating variants (PTVs) were associated with lower risk for CAD, which was dependent on lower LDL cholesterol in general population. We tested this hypothesis among Japanese heterozygous FH (HeFH) patients whose CAD risk was extremely high.
Methods
We investigated the clinical data of 2344 patients diagnosed with HeFH (mean age = 50 years, males = 1,174, median LDL cholesterol = 244 mg/dL) who were examined for their genotype of CETP and phenotypes, including the presence of CAD from 1990 to 2024 at Kanazawa University Hospital. We investigated whether PTVs of the CETP were associated with plasma lipid levels and CAD among patients with HeFH.
Results
We identified 42 patients (1.8 %) with a PTV of CETP in HeFH patients. Compared with non-carriers, carriers of a PTV of CETP had higher HDL cholesterol (effect size, 17.6 mg/dL; 95 % confidence interval [CI], 11.4 to 23.8; P < 0.001), lower LDL cholesterol (−15.4 mg/dL; 95 % CI, −24.5 to −6.3; P < 0.001), and lower lipoprotein (a) [Lp(a)] (−7.8 mg/dL; 95 % CI, −12.5 to −2.5; P < 0.001). CETP PTV carrier status was associated with reduced risk for CAD (odds ratio, 0.64; 95 % CI, 0.38 to 0.90; P < 0.001).
Conclusion
PTVs of CETP were significantly associated with higher HDL cholesterol, lower LDL cholesterol, lower Lp(a), and lower risk for CAD among patients with HeFH.
期刊介绍:
Atherosclerosis has an open access mirror journal Atherosclerosis: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Atherosclerosis brings together, from all sources, papers concerned with investigation on atherosclerosis, its risk factors and clinical manifestations. Atherosclerosis covers basic and translational, clinical and population research approaches to arterial and vascular biology and disease, as well as their risk factors including: disturbances of lipid and lipoprotein metabolism, diabetes and hypertension, thrombosis, and inflammation. The Editors are interested in original or review papers dealing with the pathogenesis, environmental, genetic and epigenetic basis, diagnosis or treatment of atherosclerosis and related diseases as well as their risk factors.
