Syncope in the German Nationwide inpatient sample – Syncope in atrial fibrillation/flutter is related to pulmonary embolism and is accompanied by hig…
2019
Syncope is a common phenomenon in the general population. Although most of the causes are of benign origin, some comorbidities are accompanied by high mortality. We aimed to compare the in-hospital mortality of patients with syncope related to different comorbities and investigate the impact of syncope in patients with atrial fibrillation/flutter (AF).The nationwide inpatient sample of Germany of the years 2011-2014 was used for this analysis. Patients with syncope (ICD-code R55) were stratified by presence of selected comorbidities. Additionally, AF patients with and without syncope were compared. Incidence of syncope and in-hospital mortality were calculated. Syncope as a predictor of adv…
Prevalence of distress, comorbid conditions and well being in the general population.
2011
Abstract Background The purposes of this paper are to determine the prevalence of distress in the community, to identify its determinants and to assess its relationship to somatic conditions and subjective well being. Methods Distress and associated factors were investigated in a random sample of 5000 participants (35–74 years) of a community-based, prospective, observational cohort study in western Mid-Germany (“Gutenberg Heart Study”) between 04/2007 and 10/2008. The sample was stratified 1:1 for gender and residence and in equal strata for decades of age. Data were assessed by self-report instruments, interviews and medical examination. Results We found a prevalence rate for depression o…
Association between +1059G/C CRP polymorphism and acute myocardial infarction in a cohort of patients from Sicily: a pilot study.
2006
Inflammation plays a role in all the phases of atherosclerosis, and increased production of the acute-phase reactant, C-reactive protein (CRP), predicts future cardiovascular events. Furthermore, CRP has been claimed to play a role in the pathogenesis of atherosclerosis; therefore, CRP polymorphisms might be associated with acute myocardial infarction (AMI). We have analyzed male patients affected by AMI and healthy age-related male controls from Sicily for +1059G/C CRP single-nucleotide polymorphism (SNP). There was a significantly higher frequency of +1059C SNP (P = 0.0008; OR 3.86) in patients compared to controls. CRP serum levels were significantly higher in C+ healthy subjects rather …
An unusual presentation of massive pulmonary embolism mimicking septal acute myocardial inferction treated with tenecteplase
2007
A 31-year-old man (175 cm, 82 kg) was referred to the emergency department 2 h after the sudden onset of acute dyspnea. Immediate ECG showed sinus tachycardia with ST elevations from V1 through V2 and a diagnosis of septal acute myocardial infarction was made. ECG on admission to the cardiology department showed the same results plus the S1-Q3-T3 pattern. Echocardiogram revealed a normally contracting left ventricle, a distended right ventricle with free wall hypokinesia and displacement of the interventricular septum towards the left ventricle. Thrombolytic therapy with tenecteplase 8000 IU and heparin 5000 IU was administered 5-10 min after hospitalisation and the patient was haemodynamic…
Left ventricular ejection fraction calculation from automatically selected and processed diastolic and systolic frames in short-axis cine-MRI
2005
International audience; Abstract: The calculation of the left ventricular ejection fraction (LVEF) is dependent upon the accurate measurement of diastolic and systolic left ventricular volumes. Although breath-hold cine magnetic resonance imaging (MRI) allows coverage of the whole cardiac cycle with an excellent time resolution, many authors rely on the visual selection of diastolic and the systolic short-axis slices in order to reduce the postprocessing time. An automatic method was developed to detect the endocardial contour on each image, allowing an automatic selection of the systolic frame. The calculated ejection fraction was compared with radionuclide ventriculography (RNV). Sixty-fi…
Cardioprotective Effects of the Na + /H + Exchange Inhibitor Cariporide in Patients With Acute Anterior Myocardial Infarction Undergoing Direct PTCA
2000
Background —Activation of Na + /H + exchange in myocardial ischemia and/or reperfusion leads to calcium overload and myocardial injury. Experimental studies have shown that Na + /H + exchange inhibitors can attenuate Ca 2+ influx into cardiomyocytes. We therefore performed a multicenter, randomized, placebo-controlled clinical trial to test the hypothesis that inhibition of Na + /H + exchange limits infarct size and improves myocardial function in patients with acute anterior myocardial infarction (MI) treated with direct PTCA. Methods and Results —One hundred patients were randomized to receive placebo (n=51) or a 40-mg intravenous bolus of the Na + /H + exchange inhibitor cariporide (HOE…
Left-hemispheric dominance for articulation: a prospective study on acute ischaemic dysarthria at different localizations.
2006
Dysarthria is a frequent symptom in cerebral ischaemia. However, speech characteristics of these patients have not previously been investigated in relation to lesion site in a prospective study. We investigated the auditory perceptual features in 62 consecutive patients with dysarthria due to a single, non-space-occupying cerebral infarction confirmed by MRI. Standardized speech samples of all patients were stored within 72 h after stroke onset using a digital tape recorder. Speech samples were assessed independently by two experienced speech therapists, who were unaware of the clinical and neuroradiological findings, using an interval scale ranging from 0 to 6. Separately assessed were fea…
Pravastatin reverses the membrane cholesterol reorganization induced by myocardial infarction within lipid rafts in CD14(+)/CD16(-) circulating monoc…
2012
International audience; Large numbers of monocytes are recruited in the infarcted myocardium. Their cell membranes contain cholesterol-rich microdomains called lipids rafts, which participate in numerous signaling cascades. In addition to its cholesterol-lowering effect, pravastatin has several pleiotropic effects and is widely used as secondary prevention treatment after myocardial infarction (MI). The aim of this study was to investigate the effects of pravastatin on the organization of cholesterol within monocyte membrane rafts from patients who had suffered myocardial infarction. Monocytes from healthy donors and acute MI patients were cultured with or without 4μM pravastatin. Lipid raf…

Advantages of immediate two-dimensional echocardiography in patients with acute cardiac ischemic events
1995
Abstract We hypothesized that the assessment of kinetic alterations on two dimensional echocardiogram (2DE) would provide greater diagnostic information than clinical symptoms and ECG changes only. The study was aimed to determine sensitivity of 2DE in patients with cardiac ischemic events and to improve the indications to thrombolysis. Three-hundred ninety-one patients (87 F; 304 M) hospitalized for suspected acute myocardial infarction (AMI), first episode, within 4 h from the onset of symptoms, suitable for thrombolysis Killip class I–II and with unstable angina (UA), were admitted in the study. Patients had to show ECG changes and alterations of segmentary motion on 2DE performed at ent…
