Correlation Study Between Percutaneous Coronary Intervention Complicated Depression and Serum Levels of Brain-derived Neurotrophic Factor, Ghrelin in Coronary Artery Disease Patients / 中国循环杂志

ABSTRACT

Objective: To explore the relationship between the incidences of percutaneous coronary intervention (PCI) complicated depression and serum levels of brain-derived neurotrophic factor (BDNF), ghrelin in coronary artery disease (CAD) patients. Methods: A total of 90 CAD patients after PCI were enrolled. According to Hamilton depression (HAMD) scale, the patients were divided into 2 groups Depression group, n=40 and Non-depression group, n=50. Serum levels of BDNF and Ghrelin were examined by ELISA and compared between 2 groups. Results: Compared with Non-depression group, Depression group had reduced serum levels of BDNF and Ghrelin, both P<0.05. As increased severity of depression, BDNF and Ghrelin were decreased accordingly; serum levels of BDNF and Ghrelin were negatively related to HAMD score (r=-0.711, P<0.05 and r=-0.711, P<0.05). Conclusion: Serum levels of BDNF and Ghrelin have an early warning effect on depression in CAD patients after PCI, it may reflect the severity of depression at certain degree in relevant patients.
