Insights
Indian patients with coronary artery disease (CAD) exhibit elevated inflammatory markers like hsCRP, IL-6, and TNF-α. These markers correlate significantly with cardiovascular risk factors such as dyslipidemia, diabetes, and hypertension.
Area of Science:
- Cardiology
- Immunology
- Biochemistry
Background:
- Inflammation plays a role in cardiovascular disease (CVD) etiology.
- Limited data exists on inflammatory markers and CVD risk factors in Indian populations.
Purpose of the Study:
- To assess the association between inflammatory markers and cardiovascular risk factors in Indian patients with coronary artery disease (CAD).
Main Methods:
- Studied 300 CAD patients for serum highly sensitive C-reactive protein (hsCRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α).
- Evaluated anthropometry and traditional/nontraditional cardiovascular risk factors.
- Utilized SPSS Version 20 for statistical analysis.
Main Results:
- Elevated mean levels of hsCRP, IL-6, and TNF-α were observed.
- Significant positive correlations found between inflammatory markers and dyslipidemia, diabetes mellitus, and hypertension.
- Progressive increase in risk factors with higher inflammatory marker levels.
Conclusions:
- Indian CAD patients present with significantly high inflammatory marker levels.
- These elevated markers are strongly associated with prevalent cardiovascular risk factors.
Background:
Inflammatory processes are implicated in the etiology of cardiovascular disease (CVD). Data on the association of inflammatory markers with cardiovascular risk factors in Indian patients with CVD are limited.
Aim:
This study was conducted with the aim to evaluate the association of inflammatory markers with traditional and nontraditional cardiovascular risk factors in angiographically proven coronary artery disease (CAD) patients.
Subjects And Methods:
We studied the association of serum highly sensitive C-reactive protein (hsCRP) (0.1-37.9 mg/l), interleukin-6 (IL-6) (2-253.2 pg/ml) and tumor necrosis factor-alpha (TNF-α) (8-525.8 pg/ml) with cardiovascular risk factors in 300 (M: 216, F: 84; mean age: 60.9 (12.4) years) CAD patients. All patients were evaluated for anthropometry and cardiovascular risk factors, and blood samples were collected for biochemical and inflammatory markers. Statistical analysis was carried out using SPSS Version 20.
Results:
Mean hsCRP, IL-6 and TNF-α in study population were 11.7 (9.7) mg/l, 64.5 (75.2) pg/ml, and 25.3 (40.9) pg/ml respectively. A total of 73.6% (221/300) patients had hsCRP levels >3.0 mg/l. All inflammatory markers were significantly higher and showed a positive correlation with dyslipidemia, diabetes mellitus, and/or hypertension (HTN). TNF-α had a negative correlation with age and positive correlation with smoking. Only IL-6 and hsCRP had a positive correlation with insulin resistance and negative correlation with insulin secretion. Among lipid parameters, triglyceride had a positive correlation, and high density lipoprotein had a negative correlation with all inflammatory markers. There was a progressive increase in the percentage of subjects with diabetes, HTN, and dyslipidemia with increasing levels of inflammatory markers.
Conclusions:
Indian patients with CAD had significantly high levels of inflammatory markers, which were related to cardiovascular risk factors.
