Hypothesis
The study aims to determine the NK cell compartment in patients with coronary heart disease undergoing coronary artery by-pass grafting.
Conclusion
Coronary heart disease is associated with an impairment of the NK cell compartment.
Supporting Evidence
- CHD patients had lower NK cytotoxic activity compared to healthy controls.
- Decreased absolute number and percentage of total NK cells were observed in CHD patients.
- Lower production of intracellular IFN-γ by NK cells was noted in CHD patients.
Takeaway
People with heart disease have fewer active immune cells called NK cells, which help fight infections.
Methodology
The study involved 93 patients with coronary heart disease and 49 healthy controls, measuring NK cell activity and composition through flow cytometry and cytotoxic assays.
Participant Demographics
Patients were undergoing elective first-time coronary artery by-pass grafting, with a median age of 63 years.
