Summary
10 papers analyzed
These studies suggest that triglyceride levels are influenced by factors such as diet, genetics, gender, and menopausal status, and that high triglyceride levels are associated with increased risks of cardiovascular disease, coronary artery disease, and all-cause mortality.

Understanding Triglyceride Ranges and Their Health Implications
Optimal Triglyceride Ranges for Health
Normal Triglyceride Levels
Triglycerides are a type of fat found in your blood, and their levels can be indicative of various health conditions. Normal triglyceride levels in plasma samples from healthy individuals typically range from 83 to 200 mg/dL. This range is considered optimal for maintaining good health and minimizing the risk of cardiovascular diseases.
Triglyceride Levels and LDL-C Estimation
A study on Korean adults found that Friedewald's formula, commonly used to estimate low-density lipoprotein cholesterol (LDL-C) from triglyceride levels, is accurate when triglyceride concentrations are between 36 and 298 mg/dL. This range ensures that the formula can be applied without significant error, making it a reliable method for estimating LDL-C in clinical settings.
Triglycerides as a Cardiovascular Risk Factor
Triglycerides and Cardiovascular Disease
Elevated triglyceride levels are a significant risk factor for cardiovascular diseases (CVD). Studies have shown that high triglyceride levels are independently associated with an increased risk of atherosclerotic cardiovascular disease (ASCVD) and all-cause mortality. For instance, individuals with non-fasting triglyceride levels of 580 mg/dL have a 5.1-fold increased risk of myocardial infarction compared to those with levels of 70 mg/dL.
Gender Differences in Triglyceride Levels
Research indicates that there are notable gender differences in triglyceride levels and their associated risks. Men generally have higher levels of large VLDL-triglycerides, while women have higher levels of very large and large HDL-triglycerides. Postmenopausal women, in particular, exhibit significantly higher levels of triglycerides across various lipoprotein subclasses compared to premenopausal women.
Triglyceride Ratios and Mortality
Triglyceride/HDL-C Ratio
The triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio is a powerful predictor of all-cause mortality and cardiovascular events, especially in women with suspected myocardial ischemia. A higher TG/HDL-C ratio is associated with increased mortality and cardiovascular events, even after adjusting for traditional risk factors such as age, race, smoking, hypertension, and diabetes.
Genetic Insights and Triglyceride-Mediated Pathways
Genetic Associations
Genetic studies have provided insights into the causal relationship between triglyceride levels and coronary heart disease (CHD). For example, the APOA5 gene variant, which regulates triglyceride concentration, has been linked to higher triglyceride levels and an increased risk of CHD. This genetic evidence supports the notion that triglyceride-mediated pathways are causally related to coronary heart disease.
Conclusion
Understanding the optimal ranges and health implications of triglyceride levels is crucial for managing cardiovascular risk. Normal triglyceride levels should ideally be between 83 and 200 mg/dL, and maintaining levels within this range can help minimize the risk of cardiovascular diseases. Elevated triglyceride levels are a significant risk factor for ASCVD and all-cause mortality, with notable differences observed between genders and across different genetic profiles. Monitoring and managing triglyceride levels, along with considering the TG/HDL-C ratio, can provide valuable insights into an individual's cardiovascular health.
