The prevalence of abnormal glucose regulation in patients with coronary artery disease across Europe. The Euro Heart Survey on diabetes and the heart.
2004
Aim The objective behind the Euro Heart Survey on diabetes and the heart was to study the prevalence of abnormal glucose regulation in adult patients with coronary artery disease (CAD). Methods and results The survey engaged 110 centres in 25 countries recruiting 4196 patients referred to a cardiologist due to CAD out of whom 2107 were admitted on an acute basis and 2854 had an elective consultation. Patient data were collected via a web-based case record form. An oral glucose tolerance test (OGTT) was used for the characterisation of the glucose metabolism. Thirty-one per cent of the patients had diabetes. An OGTT was performed on the 1920 patients without known diabetes, of whom 923 had a…
The metabolic syndrome predicts cardiovascular events in subjects with normal fasting glucose: results of a 15 years follow-up in a Mediterranean pop…
2006
The aim of this study was to evaluate the cardiovascular (CV) risk due to the metabolic syndrome in a 15-year prospective study of a Sicilian population. In the Mediterranean area obesity is highly prevalent, but epidemiological data on the metabolic syndrome are limited. Methods and results: Among the 1351 subjects enrolled in the “Ventimiglia di Sicilia” epidemiological project, we selected 687 subjects between 35 and 75 years of age; baseline parameters were assessed and subjects have been followed for 15 years recording CV events, total and cardiovascular mortality. The metabolic syndrome was defined according to both the Adult Treatment Panel III and the International Diabetes Federati…
Nitric Oxide Production and Arachidonic Acid Metabolism in Platelet Membranes of Coronary Heart Disease Patients with and without Diabetes
2001
<i>Aim:</i> To evaluate the levels of nitrite (NO<sup>–</sup><sub>2</sub>) and nitrate (NO<sup>–</sup><sub>3</sub>) ions and the incorporation of [<sup>3</sup>H]arachidonic acid (AA) into phospholipids of platelet membranes from coronary artery disease (CAD) patients with and without diabetes (NIDDM). <i>Subjects and Methods:</i> Eighteen CAD patients (group A), 18 CAD patients with NIDDM (group B), and 20 healthy controls (group C) without dyslipidemia, peripheral vascular disease and hypertension were included in the study. The groups were matched for age, sex and body mass index. The diagnosis of CAD was …
The Adverse Events and Hemodynamic Effects of Adenosine-Based Cardiac MRI
2011
OBJECTIVE We wanted to prospectively assess the adverse events and hemodynamic effects associated with an intravenous adenosine infusion in patients with suspected or known coronary artery disease and who were undergoing cardiac MRI. MATERIALS AND METHODS One hundred and sixty-eight patients (64 ± 9 years) received adenosine (140 µg/kg/min) during cardiac MRI. Before and during the administration, the heart rate, systemic blood pressure, and oxygen saturation were monitored using a MRI-compatible system. We documented any signs and symptoms of potential adverse events. RESULTS In total, 47 out of 168 patients (28%) experienced adverse effects, which were mostly mild or moderate. In 13 patie…
Association between C1019T polymorphism of connexin37 and acute myocardial infarction: a study in patients from Sicily
2003
Abstract During atherogenesis, a critical role is played by intercellular communication via gap junctions, cell membrane channels linking the cytoplasmic compartments of adjacent cells. The component protein subunits of these channels, called connexin (Cx), belong to a multigene family. Cx37 is involved in growth, regeneration after injury and ageing of the endothelial cells, suggesting its role in atherosclerosis. The C1019 single nucleotide polymorphism (SNP) of Cx37 gene was associated with thickening of the carotid intima in Swedish men and was also associated with coronary artery disease in a Taiwanese population. On the other hand, in two more recent studies performed in male Japanese…
Atrial fibrillation management: A prospective survey in ESC Member Countries - The Euro Heart Survey on atrial fibrillation
2005
Aims To describe atrial fibrillation (AF) management in member countries of the European Society of Cardiology (ESC) and to verify cardiology practices against guidelines. Methods and results Among 182 hospitals in 35 countries, 5333 ambulant and hospitalized AF patients were enrolled, in 2003 and 2004. AF was primary or secondary diagnosis, and was confirmed on ECG in the preceding 12 months. Clinical type of AF was reported to be first detected in 978, paroxysmal in 1517, persistent in 1167, and permanent in 1547 patients. Concomitant diseases were present in 90% of all patients, causing risk factors for stroke to be also highly prevalent (86%). As many as 69% of patients were symptomatic…
Inflammatory markers and cardiovascular risk in the metabolic syndrome
2011
Elevated blood glucose, obesity, high blood pressure, elevated triglycerides and low high density lipoprotein (HDL) cholesterol are well accepted risk factors in the development of coronary artery disease. Clustering of at least three of these factors in an individual is defined as metabolic syndrome (MetS). Obesity is a central pathological mechanism in the disease and it is expected that the incidence of this condition will increase dramatically within the next years. The visceral adipose tissue is not only an energy depot but also an endocrine organ which produces a large number of bioactive molecules, the so called adipokines. In the setting of obesity, the over-production of proinflamm…
Are Asthmatics Enrolled in Randomized Trials Representative of Real-Life Outpatients?
2014
<b><i>Background/Objective:</i></b> This study was aimed at exploring to what extent populations enrolled in randomized controlled trials (RCTs) of inhalation combination treatment for mild/moderate asthma in adults are fully representative of ‘real-life' populations. The following is a retrospective analysis of the clinical records of outpatient subjects with an ascertained diagnosis of asthma. <b><i>Methods:</i></b> A retrospective analysis was performed. Stable conditions, such as smoking habit and chronic diseases other than asthma, were identified as exclusion criteria for RCTs. The selected criteria were then applied to asthmatic outpati…
Haplotypes of the caspase-1 gene, plasma caspase-1 levels, and cardiovascular risk.
2006
Caspase-1 processes the interleukin (IL)-1β and IL-18 inactive precursors to the biologically active cytokines that are known to have proatherogenic effects. The present study investigated the genetic variability of the CASP1 gene and plasma levels of caspase-1 in relation to cardiovascular risk. In Europeans, 3 tag SNPs captured 4 common haplotypes of the CASP1 gene. Among these, the A in6 allele of the G+7/in6A polymorphism was less frequent in 246 cases with myocardial infarction and a parental history of disease than in 253 controls free of familial history of disease (0.13±0.02 versus 0.20±0.02; P =0.005). However, in a larger case/control study (n=1774), these effects are borderline …
Epicardial Adipose Tissue Accumulation and Essential Hypertension in Non-Obese Adults
2019
Background and Objectives: Epicardial adipose tissue (EAT) is shown to be an important factor in the development of coronary artery disease, but numerous pathophysiological mechanisms of its action are still only partially understood. There is a lack of studies on its association with different grades of essential hypertension (EH). Therefore, we aimed to evaluate the association between size of EAT depots and the risk of EH taking into account its grade. Materials and Methods: Non-obese adult patients with various cardiovascular diseases were investigated: 157 of them had essential hypertension and 101 did not. Hypertensive patients were assigned to three groups according to the grade of h…
