Impact of metabolic syndrome on left ventricular mass in overweight and obese hypertensive subjects
2007
BACKGROUND: Metabolic syndrome (MS) has been associated with an increased left ventricular (LV) mass in recent reports. Little is known about the association of MS with LV mass (LVM) in overweight and obese individuals. The aim of our study was to investigate the relation between MS and LVM in a population of overweight and obese hypertensive subjects. METHODS: 289 non-diabetic essential hypertensives with a body mass index >25 kg/m2, were enrolled. In all subjects routine blood chemistry, echocardiographic examination and 24-h ambulatory blood pressure monitoring were performed. RESULTS: In the group of overweight patients, participants with MS (n=58), when compared to those without it (n=…
Reduced Rivaroxaban Dose Versus Dual Antiplatelet Therapy After Left Atrial Appendage Closure: ADRIFT a Randomized Pilot Study.
2020
Background: Percutaneous left atrial appendage closure (LAAC) exposes to the risk of device thrombosis in patients with atrial fibrillation who frequently have a contraindication to full anticoagulation. Thereby, dual antiplatelet therapy (DAPT) is usually preferred. No randomized study has evaluated nonvitamin K antagonist oral anticoagulant after LAAC, and we decided to evaluate the efficacy and safety of reduced doses of rivaroxaban after LAAC. Methods: ADRIFT (Assessment of Dual Antiplatelet Therapy Versus Rivaroxaban in Atrial Fibrillation Patients Treated With Left Atrial Appendage Closure) is a multicenter, phase IIb study, which randomized 105 patients after successful LAAC to eith…
Percutaneous closure of left atrial appendage to prevent embolic events in high-risk patients with chronic atrial fibrillation
2009
Background: Percutaneous closure of the left atrial appendage (LAA) is a novel alternative for the treatment of patients with atrial fibrillation (AF) and with a high risk of stroke who are not eligible for long-term anticoagulation therapy. The aim of this study was to asses the safety, feasibility, and long-term efficacy of this procedure. Methods: From July 2004 to June 2007, 20 patients (13 male, mean age 69 ± 8 years) with non–valvular AF (NV-AF) underwent LAA percutaneous closure using the PLAATO™ system, implanted through a transeptal access. All patients had contraindications to anticoagulant therapy and were at high risk for cardioembolic stroke (mean CHADS2 score 3 ± 1.2). A trans…
Sex differences on new-onset heart failure in patients with known or suspected coronary artery disease
2021
Abstract Aims The impact of sex in patients with CAD has been widely reported, but little is known about the influence of sex on the risk of new-onset HF in patients with known or suspected CAD. We aimed to examine sex-related differences and new-onset heart failure (HF) risk in patients with known or suspected coronary artery disease (CAD) undergoing vasodilator stress cardiac magnetic resonance (CMR). Methods and results We prospectively evaluated 5899 consecutive HF-free patients submitted to stress CMR for known or suspected CAD. Ischaemic burden (number of segments with stress-induced perfusion deficit) and left ventricular ejection fraction (LVEF) were assessed by CMR. The association…
Dobutamine stress Doppler echocardiography: reproducibility and physiologic left ventricular filling patterns
1997
Qualitatively, dobutamine stress echocardiography has become an established procedure. Quantitative results are in great demand but this is still difficult due to limited endo- and epicardial border definition. Transmitral Doppler variables are strictly quantitative and less subjective. Furthermore, ischemic alterations precede systolic ones (ischemic cascade). There are preliminary reports of the utility of dobutamine stress Doppler echocardiography, but proof of reproducibility and left ventricular filling patterns are still lacking. Fourteen healthy volunteers (10 men, 4 women, median age 25.9 years, range 21-32 years) were investigated according to the usual dobutamine stress echocardio…
Anosognosia for hemiparesis after left-sided stroke
2014
In patients with left-sided lesions, anosognosia for hemiparesis (AHP) seems to be a rare phenomenon. It has been discussed whether this rareness might be due to an inevitable bias due to language dysfunction and whether the left hemisphere's role for our self-awareness of motor actions thus is underestimated. By applying functional magnetic resonance imaging (fMRI) we examined whether patients with AHP following a left hemisphere stroke show a regular, left-sided or a reversed, right-sided lateralization of language functions. Only the former observation would argue for an original role of the left hemisphere in self-awareness about limb function. In a consecutive series of 44 acute left-s…
Predictors of complications and mortality following left colectomy with primary stapled anastomosis for cancer: results of a multicentric study with …
2018
Aim Reports detailing the morbidity-mortality after left colectomy are sparse and do not allow definitive conclusions to be drawn. We aimed to identify risk factors for anastomotic leakage, perioperative mortality and complications following left colectomy for colonic malignancies. Method We undertook a STROBE-compliant analysis of left colectomies included in a national prospective online database. Forty-two variables were analysed as potential independent risk factors for anastomotic leakage, postoperative morbidity and mortality. Variables were selected using the 'least absolute shrinkage and selection operator' (LASSO) method. Results We analysed 1111 patients. Eight per cent of patient…
Analysis of myocardial perfusion or myocardial function for detection of regional myocardial abnormalities. An echocardiographic multicenter comparis…
2007
Background: Echocardiography based myocardial perfusion imaging and regional wall motion analysis are used for evaluation of coronary artery disease and regional myocardial abnormalities. Aim: This study sought to compare myocardial contrast echocardiography (MCE) and 2D echocardiography with regard to interobserver variability and detection of regional myocardial abnormalities. Methods: In 70 patients evenly distributed between three ejection fraction groups based on biplane cineventriculography (>55%, 35-55%, <35%), unenhanced and contrast enhanced 2D echocardiography and myocardial contrast echocardiography (MCE; SonoVue (R); Bracco) were performed. Regional watt motion and myocardial pe…
Comparison of Two- and Three-Dimensional Unenhanced and Contrast-Enhanced Echocardiographies Versus Cineventriculography Versus Cardiac Magnetic Reso…
2013
Contrast enhancement has been shown to improve detection of regional wall motion abnormalities (RWMA) in 2-dimensional (2D) echocardiography. This study determined the use of contrast enhancement in the setting of 3-dimensional (3D) echocardiography for definition of left ventricular RWMA compared with 2D echocardiography, cineventriculography, and cardiac magnetic resonance (CMR). In 63 patients, unenhanced and contrast-enhanced (SonoVue; Bracco Imaging S.p.A., Milan, Italy) 2D and 3D echocardiographies, CMR, and cineventriculography were performed. Hypokinesia in ≥1 segment defined the presence of RWMA. Interreader agreement (IRA) between 2 blinded off-site readers on presence of RWMA was…
Independent Impact of RV Involvement on In-Hospital Outcome of Patients With Takotsubo Syndrome
2016
Takotsubo syndrome (TTS) is an acute clinical condition characterized by transient left ventricular dysfunction and reversible heart failure, the pathogenetic mechanism of which remains unclear. Although left ventricular apical ballooning is the most frequent morphological pattern, other variant forms have been described (1). In addition, right ventricular involvement (RVi), characterized by the presence of right ventricular (RV) apical dysfunction (biventricular ballooning), has been documented using echocardiography or cardiac magnetic resonance imaging. However, the prevalence, clinical profile, and in-hospital course of TTS patients with RVi are still not well defined. To date, although…
