    Introduction: The new definition of periprocedural myocardial infarction (type 4a MI) excludes patients without angina and electrocardiographic or echocardiographic changes suggestive of myocardial ischemia even though significant serum troponin elevations occur following percutaneous coronary intervention (PCI). Aim: To evaluate the incidence and predictors of serum troponin rise following elective PCI in patients without clinical and procedural signs suggestive of myocardial necrosis by using a high-sensitivite troponin assay (hsTnT). Material and methods: Three hundred and four patients (mean age: 60.8 +/- 8.8 years, 204 male) undergoing elective PCI were enrolled. Patients with periprocedural angina, electrocardiographic or echocardiographic signs indicating myocardial ischemia or a visible procedural complication such as dissection or side branch occlusion were excluded. Mild-moderate periprocedural myocardial injury (PMI) and severe PMI were defined as post-PCI (12 h later) elevation of serum hsTnT concentrations to the range of 14-70 ng/l and > 70 ng/l, respectively. Results: The median pre-procedural hsTnT level was 9.7 ng/l (interquartile range: 7.1-12.2 ng/l). Serum hsTnT concentration elevated (p < 0.001) to 19.4 ng/l (IQR: 12.0-38.8 ng/l) 12 h after PCI. Mild-moderate PMI and severe PMI were detected in 49.3\% and 12.2\% of patients, respectively. Post-procedural hsTnT levels were significantly higher in multivessel PCI, overlapping stenting, predilatation and postdilatation subgroups. In addition, post-procedural hsTnT levels were correlated (r = 0.340

    Background: Radial artery occlusion (RAO) is an infrequent complication of transradial coronary procedures (TRA). To our knowledge, there is no satisfactory data regarding the late term incidence and predictors of RAO in the literature. Our aim was to establish the long-term incidence of radial artery occlusion and investigate its predictors. Methods: This was a single center prospective study. A total number of 409 consecutive patients undergoing their first TRA were recruited. Clinical and procedural data were all recorded. Doppler ultrasound examination was performed at 6-15 months following the intervention. Results: RAO was detected in 67 patients and 342 patients maintained radial artery patency. The overall RAO incidence was 16.4\% at late term. Patients with RAO were younger than the patients with patent radial arteries (55.9 +/- 9.7 vs. 59.1 +/- 9.4 years, p = 0.014). The incidence of RAO in hypertensive patients (9.8\%) was lower (p < 0.001) than the observed incidence (23\%) in non-hypertensive patients. RAO group had higher rate (28\%, p = 0.027) of post-procedural access site pain. Regression analysis revealed that hypertension was negative while post-procedural access site pain was positive independent predictors for RAO. In addition, the relative risk for RAO also increased significantly (p < 0.001) when the ratio of sheath/artery diameter (S/A) was > 1. Conclusions: The present study reveals that the long-term incidence of RAO is 16.4\%. Hypertension, post-procedural access site pain and S/A ratio > 1 are independent predictors of RAO at late term.
