| Summary: | Objectives: The aim of this study is assessment of plasma apelin levels in patients with coronary artery disease (CAD) before and after percutaneous coronary intervention (PCI).
Methods: The present study is conducted on 40 patients who underwent PCI, beside 20 healthy subjects with no risk factors or any evidence of CAD. After history taking each subject in the study underwent an electrocardiography, echocardiography for calculation of the left ventricular ejection fraction (LVEF). 22 patients underwent PCI with drug eluting stent (DES), while 18 patients underwent PCI with bare metal stents. Plasma apelin level was estimated for the control group, before, and 24 h after PCI in the patient’s group.
Results: Baseline plasma apelin level was higher in the control group versus the PCI group (385.4 ± 94.86 vs. 286.8 ± 52.93 ng/ml, p < 0.0001).There was significant rise in plasma apelin levels post PCI (428.4 ± 153.21 vs. 286.8 ± 52.93 ng/ml, p < 0.0001). There was no significant difference in plasma apelin levels pre and post PCI in patients undergoing PCI with DES versus those with bare metal stents. There were no significant correlations between plasma apelin levels pre PCI with age, gender, hypertension (HTN), diabetes mellitus, smoking, BMI, plasma cholesterol, creatinine, blood sugar level, and LVEF.
Conclusion: Apelin level increased after PCI in CAD patients, which could be an adaptive reaction for the endothelium recovery.
