Objective: Bioactive roles of adipokines in coronary atherosclerosis and acute coronary syndromes have been demonstrated previously. Ho-
wever, there is a lack of data regarding the relationship between serum adipokines and periprocedural myocardial injury (PMI) following elective percutaneous coronary intervention (PCI). Therefore, we aimed to investigate the association between serum adipokines and PMI related to elective PCI.
Methods: In total, 153 consecutive patients (aged 60.6±8.2 years, 98 men) with stable angina pectoris undergoing elective PCI were enrolled in this observational cross-sectional study. Serum resistin, leptin, adiponectin, and high-sensitive Troponin T (hscTnT) levels were measured immediately before PCI and after 12-h PCI. The no-injury, PMI, and type 4a myocardial infarction (type 4a MI) groups were defined as groups consisting patients with post-procedural hscTnT concentrations <14 ng/L, between 1470 ng/L, and >70 ng/L, respectively.
Results: Serum hscTnT, resistin, and leptin concentrations significantly (p<0.001) increased while serum adiponectin levels decreased (p<0.001) after 12-h elective PCI. However, no correlation was found between post-procedural hscTnT concentrations and resistin, leptin, and adiponectin levels. The no-injury group consisted of 65 patients (42.4%), whereas PMI and type 4a MI were observed in 70 (45.8%) and 18 (11.8%) patients, respectively. The average pre-procedural and post-procedural resistin, leptin, and adiponectin levels did not show any significant difference in the no-injury, PMI, and type 4a MI groups.
Conclusion: There is no correlation between serum adipokine levels and post-procedural troponin elevations reflecting PMI or type 4a MI. However, serum resistin and leptin levels increase, whereas adiponectin levels decrease significantly after elective PCI.
