OBJECTIVE This study surveyed the frequencies of single nucleotide polymorphisms (SNPs) M235T AGT and C825T GNB3, and their association with insulin resistance, other biochemical markers and qualitative variables in subjects with high normal blood pressure and/or prehypertension in the Greek population. DESIGN 330 men and women of Greek origin were(More)
BACKGROUND Prognostic value of NT-proBNP is well established in patients with congenital heart disease. Growing evidence suggests that plasma NGAL is elevated in heart failure but data is limited in congenital heart disease. This study investigates the combined prognostic value of plasma NGAL with plasma NT-proBNP in adult patients with congenital heart(More)
Bivalirudin is a direct thrombin inhibitor used during percutaneous coronary intervention (PCI). Treatment with bivalirudin compared to heparin plus glycoprotein IIb/IIIa inhibitors (GPI) reduced bleeding complications, but resulted in higher rates of ischemic events, including acute stent thrombosis in ST segment elevation myocardial infarction (STEMI)(More)
BACKGROUND Endovascular aortic aneurysm repair (EVAR) and transfemoral transcatheter aortic valve replacement (TAVR) are widely spreading minimally invasive procedures performed mainly through the femoral artery. Prostar XL and ProGlide vascular closure devices are used in clinical practice for the hemostasis in these procedures and they have been shown to(More)
AIMS To assess the efficacy and safety of transradial approach regardless of the Allen's test results for coronary angiography and angioplasty. METHODS AND RESULTS Prospective data collection of 1035 consecutive patients who underwent coronary angiography with or without ad hoc angioplasty through the radial approach was conducted. Baseline demographic(More)
Coronary stent delivery can be extremely challenging in tortuous and calcified lesions especially when radial approach is chosen. Guide extension catheter is a useful tool for overcoming the inherent difficulties arising by the use of radial access in complex percutaneous interventions. We describe a technique for guide extension catheter system advancement(More)
OBJECTIVES The aim of this study is to identify possible predictors for same day discharge (SDD) after percutaneous coronary interventions (PCI). BACKGROUND Same day discharge after PCI is becoming more and more appealing and patient's selection criteria are being formulated. METHODS A retrospective analysis was performed in all PCI procedures from(More)
Chronic skeletal muscle ischemia protects the ischemic heart by preserving coronary flow and inducing arterioangiogenesis. We sought to determine the effect and the underlying molecular mechanisms of preconditioning (PreC) and postconditioning (PostC), applied in a model of chronic skeletal muscle ischemia. Male rabbits were divided into 3 series. In each(More)
