BACKGROUND There is serological evidence for an association between Chlamydia pneumoniae and coronary heart disease. We investigated the hypothesis that an antichlamydial macrolide antibiotic, roxithromycin, can prevent or reduce recurrent major ischaemic events in patients with unstable angina. METHODS The effect of roxithromycin was assessed in a(More)
AIMS Mounting evidence suggests infection, specifically Chlamydia pneumoniae, plays a role in atherosclerosis. We tested whether antibiotic treatment with the macrolide roxithromycin improves clinical outcome in patients with acute non-Q-wave coronary syndromes. Preliminary reports revealed a reduction in events in the roxithromycin group at 30 days. We now(More)
BACKGROUND Whether the clinical superiority of enoxaparin versus unfractionated heparin (UFH) depends on a more stable antithrombotic effect or the proportion of patients not reaching the therapeutic level with UFH has not been addressed. METHODS All patients participating in the Thrombolysis In Myocardial Infarction 11B trial who received UFH and had(More)
BACKGROUND The aim of this article was to investigate whether prior aspirin use in patients with acute coronary syndromes affects clinical outcome. The Efficacy Safety Subcutaneous Enoxaparin in Non-Q-Wave Coronary Events Study (ESSENCE) and Thrombolysis in Myocardial Infarction (TIMI) 11B trials have shown superiority of enoxaparin over unfractionated(More)
BACKGROUND Information regarding predisposing factors, frequency, and prognostic implications of new onset atrial fibrillation (NOAF) after carotid endarterectomy (CEA) is scarce. We assessed the frequency, risk factors, and the prognostic impact of NOAF after CEA. METHODS We assessed every patient undergoing CEA (n = 186) at our academic hospital between(More)
Recently, authors of several studies on acute coronary syndromes have reported that study participants from eastern Europe and South America had poorer outcomes compared to their North American and western European counterparts. Taking into consideration that all of these studies have in common a very small proportion of participants from regions outside(More)
Background: This study was designed to analyze the impact of treatment with either unfractionated heparin or enoxaparin (low molecular weight heparin) on plasma markers of thrombotic and endogenous thrombolytic activity in patients with non-ST segment elevation acute coronary syndromes. Methods: A subset of 174 patients derived from the 3,171 patients of(More)
Ischemic electrocardiographic changes were recorded within 2 hours of admission using a 12-lead electrocardiographic continuous monitor with a 20-second scanning interval and an alarm mode for asymptomatic events. Blood samples were obtained at admission and at the moment of asymptomatic events (group A). In the other patients who did not develop ischemia,(More)
Coronary heart disease remains the most common cause of death in industrialized countries. Although atherosclerosis is generally asymptomatic in the early stages, progressive plaque development leads to arterial stenosis which is characterized by angina and may eventually lead to unstable angina, myocardial infarction and cardiac death. Evidence that the(More)
Systemic serum markers of inflammation are elevated in diseases due to atherosclerosis, but have not been associated with the extent of atherosclerotic disease. We examined the role of neopterin, a byproduct of activated macrophage metabolism, in patients with unstable angina. Baseline neopterin samples and clinical histories were obtained in 52 patients(More)
