Effects of exercise training on oxygen uptake in coronary heart disease: a systematic review and meta-analysis
2010
It is not known to what extent exercise programs increase maximal oxygen uptake (VO(2max)) in patients with coronary heart diseases (CHD). The purpose of this study is to determine the effect of exercise interventions on VO(2max) in subjects with CHD. Database search of randomized controlled trials was conducted from PubMed. Studies were included that reported the characteristics and effects of exercise interventions in subjects with CHD, included a non-exercise control group and measured VO(2max) using direct measurement method. Eighteen studies were eligible. Exercise interventions increased VO(2max) by 2.6 +/- 1.6 and 0.3 +/- 1.4 mL/kg/min in the training and control groups, respectively…
Effect of comprehensive vasodilation vs usual care on mortality and heart failure rehospitalization in women with acute heart failure
2020
Abstract Background Guidelines recommend evaluating the risk/benefit ratio of novel therapies individually in women and men, as the pathophysiology and the response to treatment may differ between women and men. Among patients with acute heart failure (AHF), a strategy of intensive vasodilation, compared with usual care, overall did provide comparable outcomes. Purpose To evaluate the effect of a strategy that emphasized early intensive and sustained vasodilation in women with AHF. Methods In a randomized, open-label blinded-end-point trial patients hospitalized for AHF were enrolled in 10 hospitals in Switzerland, Bulgaria, Germany, Brazil, and Spain. Inclusion criteria were AHF expressed …
Sustained reentry in a 3d regionally ischemic human heart. A simulation study
2016
In this work, we have studied the vulnerable window and propagation patterns in a human heart during acute ischemia. A 3-D biventricular model of a human heart with realistic heterogeneity and fiber orientations has been considered. The ischemic region was located in the anterior left ventricular wall mimicking the occlusion of the circumflex artery. The electrical activity of the tissue was modeled with the monodomain model along with a modified version of the ten Tusscher 2006 ionic model. The model predicts the generation of sustained re-entrant activity in the form of a rotor around the ischemic zone. Patterns in the form of figure-of-eight were also observed within the vulnerable windo…
Available Instruments to Assess Pain in Infants
2021
Pain assessment in newborns and infants is challenging for clinicians. Although behavioral and behavioral-physiological scales are validated pain assessment instruments, their use in this age group has significant limitations. In this review, we summarize the methods currently available for assessing pain in neonates and infants. It is possible that these pain detection methods are also useful for assessing the quality of anesthesia and analgosedation in these populations. Further research should be aimed at confirming the usefulness of these tools in infants and identifying additional pain assessment options for clinical practice.
Management of Antiaggregated and Anticoagulated Patients Scheduled for Thoracic Surgery: Recommendations for Venous Thromboprophylaxis
2017
The management of patients under the effect of antiplatelet or anticoagulant agents is a common challenge in thoracic surgery. Their temporary interruption or continuation needs a balanced assessment between the risk of thrombosis (interruption) and bleeding (continuation). Moreover, most patients must receive an anticoagulant for thromboprophylaxis (mainly a low-molecular-weight heparin). So, it is important to have in mind all surgical and anaesthetic implications of these drugs to take the optimal decision in each case.
Role of CRT upgrading in pacing induced heart failure: A case report
2014
Abstract We submit a case report of a 78-year-old male came to our department for systolic heart, failure (EF of 25%). He has clinical history of recurring atrial tachycardia and atrial flutter previously treated in our department unsuccessfully with antiarrhythmic drug therapy. The echocardiographic evidence of left atrial enlargement (left atrium area 40 cm 2 ) and the clinical history of permanent atrial tachycardia has discouraged any attempt of substrate ablation. As it is impossible get rhythm and rate control with drug therapy, the patient was subjected to an "ablate and pace" procedure with implantation of a VVIR mode pacemaker. Also, for the absence of indications (QRS width During…
Gradual angioplasty and stent implantation to treat complete superior vena cava occlusion after Mustard procedure
1996
A 16-year-old male was admitted with complete occlusion of the superior vena cava pathway 14 years after Mustard procedure for transposition of the great arteries. From a left subclavian vein approach, the atretic vein segment was perforated using a straight guidewire, and was followed by sequential balloon dilation. Implantation of a 30 mm Palmaz-stent through a femoral vein approach resulted in a widely patent channel of the vena cava superior into the systemic venous atrium. © 1996 Wiley-Liss, Inc.
Effect of a Biofeedback Intervention on Heart Rate Variability in Individuals With Panic Disorder: A Randomized Controlled Trial
2021
OBJECTIVE Some individuals with panic disorder (PD) display reduced heart rate variability, which may result in an increased risk of cardiovascular mortality. Heart rate variability-biofeedback (HRV-BF) training has been shown to improve the modulation of the autonomic activity. Therefore, this randomized controlled trial was conducted to investigate the effect of a four-week HRV-BF intervention in individuals with PD. Heart rate variability-biofeedback (HRV-BF) training improved the modulation of the autonomic activity. Therefore, with this randomized controlled trial we aimed to investigate the effect of a four-week HRV-BF intervention in people with PD. METHODS Thirty-six women and sixte…
0190: Predictive factors of intrahospital mortality in patients with right ventricular myocardial infarction
2016
IntroductionRight ventricular (RV) infarction is a serious and life threatening condition which mainly complicates an inferior wall myocardial infarction (MI). In the literature, data for predictive factors of mortality in this setting remains scarce.Aim to study predictive factors of intrahospital mortality in patients with RV infarction.Methods and resultsData was collected from a monocenter registry including all patients with AMI admitted in our department between January 1995 and March 2013. 1483 patients were enrolled in our registry. RV infarction was diagnosed in 160 (10.7%) patients, always complicating an inferior wall MI. 37 (23.1%) patients presented with right sided heart failu…
Cuantificación y tratamiento de la congestión en insuficiencia cardíaca: una visión clínica y fisiopatológica
2022
Renal sodium and water retention with resulting extracellular volume expansion and redistribution are hallmark features of heart failure syndromes. However, congestion assessment, monitoring, and treatment represent a real challenge in daily clinical practice. This document reviewed historical and contemporary evidence of available methods for determining volume status and discuss pharmacological aspects and pathophysiological principles that underlie diuretic use.
