Normalwerte für die Dobutamin-Streßechokardiographie*
2008
UNLABELLED Dobutamine stress echocardiography having established itself as a sensitive method for diagnosing coronary heart disease, even in the absence of normative values, the physiological haemodynamics as well as the physiological values for global and regional left ventricular myocardial function were measured. TEST PERSONS AND METHODS 14 healthy subjects (ten men, four women; median age 25 [range 21-32] years) underwent dobutamine stress echocardiography according to an internationally practised dosage steps protocol (5-40 micrograms/kg/min with additional 0.5 mg atropine at 40 micrograms). RESULTS Maximal infusion rate achieved a serum dobutamine level of 1.67 micrograms/ml with mini…
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…

P776 Stress ecocardiography and speckle tracking analysis in patients with heart failure and preserved ejection fraction
2020
Abstract BACKGROUND Heart failure with preserved ejection fraction (HFpEF) is characterized by heart failure symptoms despite preserved LV systolic function together with at least one among left ventricle hypertrophy/left atrial enlargement plus diastolic dysfunction (DD) and increased brain natriuretic peptide levels. Rest echocardiography could still be normal despite patients experience HF symptoms. Speckle tracking analysis (STE) analyzes myocardial deformation and is able to identify subtle left ventricular dysfunction. PURPOSE to analyze the added value of stress echocardiography to improve diagnostic accuracy in patients with normal ejection fraction and unexplained dyspnoea by evalu…
P3543Rehospitalization burden in heart failure with mid-range ejection fraction and morbidity burden. Is it a distinct phenotype?
2019
Abstract Heart failure with mid-range ejection fraction (HFmrEF) has been recognized as a distinct HF phenotype, but wether patients on this category fare worse, similarly, or better than those with HF with reduced EF (HFrEF) or preserved EF (HFpEF) in terms of rehospitalization risk over time remains unclear. We therefore sought to characterize the mordibity burden of HFmrEF patients by evaluating the risk of recurrent hospitalizations following an admission for acute HF. Methods We prospectively included 2,961 consecutive patients discharged for acute HF in our institution from 2004 to 2017. Patients were categorized according to their ejection fraction (EF) obtained by an echocardiograph…
Right heart dysfunction and readmission risk across left ventricular ejection fraction status in patients with acute heart failure
2021
Abstract Background Right heart dysfunction (RHD) parameters, such as right ventricular to pulmonary artery uncoupling or significant tricuspid regurgitation (TR) are increasingly important in heart failure (HF), especially in patients with preserved ejection fraction. In this study, we aimed to evaluate the association of advanced RHD with the risk of recurrent admissions across the spectrum of left ventricular ejection fraction (LVEF). Methods We included 3,383 consecutive patients discharged for acute HF (AHF). Of them, in 1,435 (42.4%) pulmonary artery systolic pressure (PASP) could not be accurately measured, leaving a final sample size of 1,948 patients. Advanced RHD was defined as th…
Sex-related differences in mortality following an admission for acute heart failure across left ventricular ejection fraction spectrum
2021
Abstract Background Prognosis in heart failure (HF) may differ between women and men. However, data is conflicting and sex-related differences in prognosis may be determined by left ventricular ejection fraction (LVEF) status. We sought to evaluate the prognostic differences between women and men with HF following an admission for acute HF (AHF). Methods We included 4,812 patients consecutively admitted for AHF in a multicenter registry from 3 hospitals in Valencia (Spain). Study endpoints were all-cause, cardiovascular (CV), and HF-related mortality at 6-months follow-up. Multivariable Cox regression models were fitted to investigate sex-related differences across LVEF status. Results 2,24…
Hemodynamic Effects of Ventricular Pacing
1985
Fixed rate ventricular pacing is used in most cases of implanted pacemakers. It does not usually create considerable hemodynamic problems, as the heart, by its adaptation mechanism, is capable of varying its pump performance to meet the metabolic needs[1,3].
