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 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)
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)
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)
BACKGROUND Natural disasters, war, and terrorist attacks, have been linked to cardiac mortality. We sought to investigate whether a major financial crisis may impact on the medical management and outcomes of acute coronary syndromes. METHODS We analyzed the Argentine cohort of the international multicenter Global Registry of Acute Coronary Events (GRACE).(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)
OBJECTIVES Evidence exists showing an association between Chlamydial infection and infarction. Our purpose was to identify an interactive relationship between Chlamydia pneumoniae and unstable angina. METHODS We analyzed IgG antibodies for Chlamydia pneumoniae, Mycoplasma pneumoniae, and C reactive protein in patients during the acute phase of unstable(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)
