Abstract:
BACKGROUND:Natural killer (NK) cells are the potential modulators of inflammatory reactions that exert several unique biological effects and could lead to future adverse events of coronary artery disease (CAD). HYPOTHESIS:The purpose of this study was to find out the possible association of modulation in NK cell, TNK cells, T cells, B cells, and tumor necrosis factor alpha (TNF-α) in CAD patients and various forms of myocardial infarction. METHODS:The present study included total 190 subjects (98 confirmed CAD patients both men and women and 92 healthy control individuals). Serum concentration of TNF-α was measured by ELISA method. For the measurement of various immune cells, viz., NK cell, TNK cells, T cells, and B cells, flow-cytometric analysis was performed. RESULTS:A significant reduction by 15% (P < 0.001) in CD16/CD56 NK cells was observed in CAD patients. Moreover, non-ST segment elevation myocardial infarction (NSTEMI), ST segment elevation myocardial infarction (STEMI), unstable angina (UA), and combined UA + NSTEMI group also showed a significant decline in NK cells compared with control individuals. CD16/CD56/CD3 TNK cells showed a significant reduction in CAD, NSTEMI, STEMI, and UA categories. However, UA + NSTEMI group did not show any significant change in TNK cells. On the other hand, the level of TNF-α was found to be significantly elevated in CAD, STEMI, and UA groups. NSTEMI and combined UA + NSTEMI group did not show any significant change in TNF-α level. CONCLUSION:Current study provides an insight toward the association of immune cells and inflammation with CAD.
