Objectives: We aimed to evaluate the correlation between the preprocedural serum lipid levels and the extent of periprocedural myocardial injury (PMI) in patients undergoing elective percutaneous coronary intervention (PCI). Background: PMI is accepted as a predictor of in-hospital cardiac events and long term adverse outcomes following PCI. Methods: The study group consisted of 195 patients (60.10.7 years old; 68 female and 127 males) undergoing elective PCI. Serum hscTnT concentrations were measured in blood samples obtained immediately before PCI and 12 hours after PCI. Serum total cholesterol (TC), low density lipoprotein- cholesterol (LDL-C), high density lipoproteincholesterol (HDL-C) and triglyceride (TG) levels were determined immediately before PCI. Results: The average pre-procedural hscTnT concentration was 8.10.2 ng/L. The average serum hscTnT concentration elevated to 34.12.8 ng/L (p<0.001) 12-hours after PCI. Post-procedural hscTnT concentrations were positively correlated to serum concentrations of TC (r¼0.435; p<0.001), LDL-C (r¼0.349; p<0.001) and TG (r¼0.517; p<0.001). Post-procedural hscTnT concentrations were significantly higher in patients with high serum TC (200 mg/dL), LDL-C (100 mg/dL) and TG (150 mg/dL) than the values observed for patients with normal serum concentrations of these lipid parameters. PMI and type 4a MI were observed in 95 (48.7%) and 27(13.9%) patients, respectively. The patients with type 4a MI had high serum TC (p<0.001), LDL-C (p<0.001) and TG (p<0.001) concentrations. Conclusions: Our findings clearly show that high serum levels of pre-procedural TC, LDL-C and TG are associated with significant elevations of hscTnT reflecting severe peri-procedural myocardial injury. These findings lead to the clinical implication that improving pre-procedural serum lipid status of patients could have beneficial effects for decreasing myocardial injury during PCI. Initiating statin treatment in patients who will undergo elective PCI could reduce periprocedural myocardial injury by not only inducing anti-inflammatory and plaque stabilizing effects but also improving serum lipid status of patients.

- OP-91 Transradial Catheterization Decreases the Radial Artery Luminal Diameter and Impairs Vasodilatation Response at the Access Site Late after the Intervention: an Observational Study.

Objectives: The present study aimed to evaluate the late term changes in radial artery luminal diameter (RAD) and vasodilatation response following transradial coronary intervention (TRI). Background: TRI inducing a trauma to radial artery intima may trigger chronic phase vascular changes and lead to anatomical and functional impairment. There is controversial data whether the impairment persists or repairs later. Methods: Fifty six consecutive patients undergoing TRI were enrolled prospectively. Baseline luminal diameter, flow associated dilatation (FAD) and nitroglycerin mediated dilatation (NMD) of the radial artery at the access site were measured before TRI by using high resolution ultrasound. Six months later; RAD, FAD and NMD were measured again at the same access site. Results: RAD at the sixth month was reduced compared with preprocedural measurements (2.74 0.42 mm vs 2.85 0.44 mm, p¼ 0.0001).The average FAD decreased to 5.66 5.87 %, which was significantly lower than the observed pre-procedural FAD (9.45 5.01 %) six months after TRI (p¼0.0001). Likewise, the average NMD at the sixth month was reduced compared with pre-procedural NMD (6.64
