The role of inflammation in the development of restenosis after percutaneous coronary interventions has been investigated in several studies. There is an interaction of inflammatory activation and vascular wall response to injury leading to intimal hyperplasia. Percutaneous interventions trigger inflammatory reactions leading to the development of intimal(More)
This study aimed to assess regional and directional differences in the mechanical properties of ascending thoracic aortic aneurysms (ATAA). Whole fresh ATAA were taken from twelve patients, undergoing elective surgical repair, and cut into tissue specimens. These were divided into groups according to direction and region, and subjected to uniaxial testing(More)
OBJECTIVES We investigated the midterm clinical significance of human coronary atherosclerotic plaques temperature after a successful percutaneous coronary intervention. BACKGROUND Previous studies have shown an increased temperature in human atherosclerotic plaques. However, the prognostic significance of atherosclerotic plaque temperature in patients(More)
BACKGROUND Activated macrophages play an important role in the pathogenesis of acute ischemic syndromes. It has been postulated that detection of heat released by activated inflammatory cells of atherosclerotic plaques may predict plaque rupture and thrombosis. Previous ex vivo studies have shown that there is thermal heterogeneity in human carotid(More)
AIMS Heat released from atherosclerotic plaques as a result of the local inflammatory process, may be measured in vivo by a thermography catheter. Statins seem to have an antiinflammatory effect which results in plaque stabilization. The aim of this study was to investigate the effect of statins on plaque temperature. METHODS AND RESULTS The study(More)
To assess left atrial mechanical function in the elderly, 35 old (age > 70 years) and 18 sex-matched young (age < 50 years) healthy subjects were studied. Transmitral flow velocities were recorded with pulsed Doppler echocardiography. Left atrial volumes were measured echocardiographically at mitral valve opening (maximal) and closure (minimal) and at onset(More)
OBJECTIVES The aim of the present study was to assess the efficacy of remote ischemic post-conditioning (RIPC) by repeated intermittent balloon inflations in preventing acute kidney injury (AKI) in patients with a non-ST-segment elevation myocardial infarction undergoing percutaneous coronary intervention (PCI). BACKGROUND AKI complicating PCI is(More)
OBJECTIVE The purpose of this study was to evaluate the impact of ATLS(®) on trauma mortality in a non-trauma system setting. ATLS represents a fundamental element of trauma training in every trauma curriculum. Nevertheless, there are limited studies in the literature as for the impact of ATLS training in trauma mortality, especially outside the US. (More)
Inflammatory processes play a pivotal role in the pathogenesis of atherosclerosis and mediate many of the stages of atheroma development, from initial leukocyte recruitment to eventual rupture of the unstable atherosclerotic plaque. Several systemic inflammatory markers reflect different degrees of inflammation and have been indicated as independent risk(More)
IMPORTANCE OF THE FIELD Hypercholesterolemia holds a key role in the development and progression of atherosclerosis and is a causative factor of coronary artery disease. Current guidelines for cholesterol treatment target low-density cholesterol (LDL-C) as the primary goal of therapy. Despite advances in the pharmacotherapy of atherosclerosis, the most(More)
