Dyslipidemia: Genetics, lipoprotein lipase and HindIII polymorphism [version 2; referees: 2 approved]
The direct link between lipid metabolism alterations and the increase of cardiovascular risk are well documented. Dyslipidemias, including isolated high LDL-c or mixed dyslipidemia, such as those seen in diabetes (hypertriglyceridemia, high LDL-c or low HDL-c), correlate with a significant risk of cardiovascular and cerebrovascular disease worldwide. This review analyzes the current knowledge concerning the genetic basis of lipid metabolism alterations, emphasizing lipoprotein lipase gene mutations and the HindIII polymorphism, which are associated with decreased levels of triglycerides and LDL-c, as well as higher levels of HDL-c. These patterns would be associated with decreased global morbidity and mortality, providing protection against cardiovascular and cerebrovascular diseases
Non-HDL cholesterol is better than LDL-c at predicting atherosclerotic cardiovascular disease risk factors clustering, even in subjects with near-to-normal triglycerides: A report from a Venezuelan population
Background: Non-high density lipoprotein cholesterol (non-HDL-c) has
emerged as an important tool in primary prevention of atherosclerotic
cardiovascular disease (ASCVD), especially among those at high risk. The
main objective of this study was to evaluate the predictive value of non-HDL-c
for the coexistence aggregation of multiple ASCVD risk factors and compare
this with LDL-c in general subjects with normal or near normal triglycerides from
Maracaibo city in Venezuela.
Methods: This is a descriptive, cross-sectional study with a randomized
multistage sampling. 2026 subjects were selected for this study, all were adults
â„18 years old of both genders and inhabitants of Maracaibo city, Venezuela. A
complete history and physical medical assessment was performed. A
multivariate logistic regression model was used to determine the odds ratio
(CI95%) for the coexistence of multiple risk factors for ASCVD.
Results: The median (p25-p75) of non-HDL-c was 143 mg/dL (114-174
mg/dL). 52.1% (n=1056) of the sample were women, with a median of 144
mg/dL (115-174 mg/dL) among women and 143 mg/dL (114-17 4mg/dL)
among men; p=0.740. Individuals â„50 years old, smokers, those with
hypertension, obesity, diabetes, high waist circumference and elevated hs-C
Reactive Protein, all had higher levels of non-HDL-c. A lower median was observed among those <30 years of age with elevated physical activity levels in
their leisure time. Non-HDL-c between 130-159 mg/dL (OR=2.44; CI
95%=1.48-4.02; p<0.001) and â„160 mg/dL (OR=3.28; CI 95%=1.72-6.23;
p<0.001) was associated with greater risk of coexistent multiple risk factors for
ASCVD, albeit LDL-c was not significant in the multivariate model.
Conclusions: Elevated non-HDL-c was associated with conglomeration of
multiple risk factors for ASCVD. This suggests evaluation of non-HDL-c may be
of better utility in primary care for early identification of subjects for high risk of
ASCVD. Future research might focus on the influence of non-HDL-c in
cardiovascular mortality
