Insights
Coronary heart disease (CHD) patients exhibit higher lipid levels and atherogenic indexes, alongside lower paraoxonase 1 (PON1) activity and high-density lipoprotein cholesterol (HDL-C). These findings highlight key biomarkers for CHD risk assessment and management.
Area of Science:
- Biochemistry
- Cardiology
- Clinical Medicine
Background:
- Dyslipidemia is a significant independent risk factor for coronary heart disease (CHD).
- Paraoxonase 1 (PON1) activity and lipid profiles are crucial in cardiovascular health.
- Atherogenic indexes provide insights into cardiovascular risk.
Purpose of the Study:
- To compare paraoxonase 1 (PON1) activity, lipid profiles, and atherogenic indexes between coronary heart disease (CHD) patients and healthy controls.
- To investigate the relationship between PON1 activity, high-density lipoprotein cholesterol (HDL-C), and atherogenic indexes in CHD patients.
Main Methods:
- A case-control study involving 50 CHD patients and 50 matched healthy controls.
- Analysis of serum PON1 activity, triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), very low-density lipoprotein (VLDL), HDL-C, and fasting blood glucose (FBG).
- Statistical analysis using unpaired Student's t tests and Pearson's correlation analysis.
Main Results:
- CHD patients showed significantly higher levels of TG, TC, LDL, VLDL, FBG, and atherogenic indexes compared to controls.
- Significantly lower PON1 activity and HDL-C levels were observed in CHD patients.
- PON1 activity positively correlated with HDL-C and negatively with atherogenic coefficients and cardiac risk ratios in CHD patients.
Conclusions:
- Coronary heart disease is strongly associated with elevated lipid levels, increased atherogenic indexes, and diminished PON1 activity and HDL-C concentrations.
- These biochemical markers are pivotal in understanding CHD pathophysiology.
- Effective management of CHD necessitates addressing lipid abnormalities and potentially augmenting PON1 activity or HDL-C levels.
Background:
Dyslipidemia is considered an independent risk factor for coronary heart disease (CHD). In the present study, we examined lipid profiles and paraoxonase 1 (PON1) activity and atherogenic indexes status and the relationship of PON1 activity by high-density lipoprotein (HDL) and atherogenic indexes in CHD patients and healthy people.
Methods:
The aim of the study was to compare PON1, lipid profiles, and atherogenic indexes in CHD patients and healthy people as controls. This study enrolled 50 CHD patients and 50 matched healthy controls. Serum activities of PON1 and levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL), very low density lipoprotein (VLDL), high-density lipoprotein cholesterol (HDL-C), fasting blood glucose (FBG), and atherogenic indexes were analyzed. Data were analyzed by unpaired Student's t tests. Coefficients of correlation were calculated using Pearson's correlation analysis.
Results:
Levels of TG, TC, LDL, VLDL, FBG, and atherogenic indexes, atherogenic coefficients, and cardiac risk ratios were significantly greater in CHD patients than in controls. Paraoxonase 1 activity and HDL-C levels were significantly less in CHD patients than in controls. Also, PON1 activity correlated positively with HDLC and negatively with atherogenic coefficient, and cardiac risk ratios 1 and 2 in CHD patients.
Conclusion:
This study showed that CHD is associated with high lipid levels and atherogenic indexes, and low PON1 activity and HDL-C concentrations. Coronary heart disease is a pernicious disease requiring prolonged medical management and hypolipidemic drugs.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
