Interleukin-18 Is a Strong Predictor of Cardiovascular Death in Stable and Unstable Angina
2002
Background — Interleukin (IL)-18 plays a central role in orchestrating the cytokine cascade and accelerates atherosclerosis and plaque vulnerability in animal models. However, epidemiological data evaluating the role of IL-18 levels in atherosclerosis are lacking. Methods and Results — In a prospective study of 1229 patients with documented coronary artery disease, we measured baseline serum concentrations of IL-18 and other markers of inflammation. During the follow-up period (median, 3.9 years), 95 patients died of cardiovascular causes. Median serum concentrations of IL-18 were significantly higher among patients who had a fatal cardiovascular event than among those who did not (68.4 ve…
Cocaine-induced coronary thrombosis and acute myocardial infarction
2004
A 26-year-old man was admitted to our hemodynamic laboratory because of an anterior AMI and post myocardial infarction angina. He is an active smoker (10 cigarettes/day) and consumes inhaled cocaine during weekends (the last consumption of cocaine was 1 week ago). No others risk factors were recorded. Initial electrocardiogram shows sinus rhythm and anterior QS complex (V1–V3) with anterolateral ST segment elevation (V1–V5, D1 and aVL). Creatine-kinase isoenzyme MB and Troponin I were elevated at arrival. Upon admission, the patient was normotensive but with signs of pulmonary congestion. Ventriculography showed anterolateral and apical hypokinesia with an ejection fraction of 21%. Coronari…
013 Pre-infarction angina and cardiovascular complications in non ST segment elevation myocardial infarction: Data from the RICO survey
2010
BackgroundThe presence of preinfarction angina (PIA) has been shown to confer cardioprotection after ST segment elevation myocardial infarction (MI). However, the impact of PIA in non ST segment elevation (NSTEMI) remains to be determined.Patients and MethodsFrom the obseRvatoire des Infarctus de Côte d’Or (RICO) survey, 1541 consecutive patients admitted in intensive care unit with a first NSTEMI were included in the study. Patients who experienced chest pain 1) and 30-day mortality were collected.ResultsAmong the 1541 patients included in the study, 693 patients presented PIA. Baseline clinical characteristics were similar for the 2 groups. There was no significant difference for the GRAC…
Neopterin, cellular adhesion molecules and myeolperoxidase in patients with stable and unstable angina pectoris
2011
Neopterin, cellular adhesion molecules and myeolperoxidase in patients with stable and unstable angina pectoris Recent data indicate that the serum level of neopterin, a marker of inflammation and immune modulator secreted by monocytes/macrophages, is elevated in patients with acute coronary syndrome (ACS) and seems to be a prognostic marker for major cardiovascular events. Soluble cellular adhesion molecules (sCAMs) and myeloperoxidase (MPO) levels are also related to ACS. The aim of the present study was to evaluate differences in serum levels of neopterin, sCAMs and MPO between coronary artery disease and metabolic syndrome (CAD-MetS) patients with stable and unstable angina pectoris (SA…
Non-Hemodynamic Effects of Organic Nitrates and the Distinctive Characteristics of Pentaerithrityl Tetranitrate
2009
Organic nitrates are among the oldest and yet most commonly employed drugs in the long-term therapy of coronary artery disease and congestive heart failure. While they have long been used in clinical practice, our understanding of their mechanism of action and side effects remains incomplete. For instance, recent findings provide evidence of previously unanticipated, non-hemodynamic properties that include potentially beneficial mechanisms (such as the induction of a protective phenotype that mimics ischemic preconditioning), but also toxic effects (such as endothelial and autonomic dysfunction, rebound angina, tolerance). To date, the most commonly employed organic nitrates are isosorbide …
Visualizing the atherosclerotic plaque: a chemical perspective.
2014
Atherosclerosis is the major underlying pathologic cause of coronary artery disease. An early detection of the disease can prevent clinical sequellae such as angina, myocardial infarction, and stroke. The different imaging techniques employed to visualize the atherosclerotic plaque provide information of diagnostic and prognostic value. Furthermore, the use of contrast agents helps to improve signal-to-noise ratio providing better images. For nuclear imaging techniques and optical imaging these agents are absolutely necessary. We report on the different contrast agents that have been used, are used or may be used in future in animals, humans, or excised tissues for the distinct imaging moda…
Indicaciones actuales de revascularización
2012
Randomized controlled trials in patients with chronic ischemic heart disease and stable angina indicate that the majority of cases can be managed by optimum medical treatment. The exceptions are patients with conditions that could benefit from revascularization, such as recurrent angina, extensive inducible ischemia or complex coronary anatomy. However, since studies have traditionally excluded patients with significant comorbidity, it is not clear which treatment approach would be best in these circumstances. Although patients with comorbidities are usually treated conservatively in routine clinical practice, some recent studies in elderly patients have raised the possibility that this sub…
Coronary microvascular dysfunction
2020
Patients with coronary microvascular dysfunction (CMVD) represent a widespread population and despite the good prognosis, many of them have a poor quality of life with strong limitations in their daily activities because of the angina symptoms. This article summarizes the most frequent clinical presentation pictures like stable and unstable microvascular angina. Main risk factors are discussed, followed by the latest updates on the subject about different pathogenic hypotheses, diagnosis and treatment. Not very well understood microvascular alterations, like slow flow phenomenon and no reflow are discussed and both prognosis and the impact of the disease in the quality of life are analyzed.
Angina bullosa hemorrhagica, an uncommon oral disorder. Report of 4 cases
2020
Angina bullosa hemorrhagica (ABH) is a rare oral disorder characterized by blood-filled bullous lesions in the oral cavity and the oropharynx in the absence of an underlying systemic, haematological or mucocutaneous condition. The presentation of the lesions is acute and located on the lining mucosa, mainly on the soft palate. Often, these lesions are single and rupture easily leaving an ulcerated area. In this study, we present 4 ABH cases in 3 women and 1 man and we discuss the main clinicopathological characteristics. The characteristics of this disorder are important to recognize in order to differentiate the lesions from other oral bullous conditions of the oral cavity such as mucocuta…
Atherosclerosis, inflammation and Chlamydia pneumoniae
2009
Coronary heart disease is the single most common cause of illness and death in the developed world. Coronary atherosclerosis is by far the most frequent cause of ischemic heart disease, and plaque disruption with superimposed thrombosis is the main cause of the acute coronary syndromes of unstable angina, myocardial infarction, and sudden death. Atherosclerosis is the result of a complex interaction between blood elements, disturbed flow, and vessel wall abnormality, involving several pathological processes: inflammation, with increased endothelial permeability, endothelial activation, and monocyte recruitment; growth, with smooth muscle cell proliferation, migration, and matrix synthesis; …
