1. Strain Magnitude Assessed at Rest and During Stress Echocardiography in Patients with Normal Coronary Flow Reserve
Abstract Background Coronary flow and myocardial contractile performance assessed by strain magnitude increase during a dobutamine stress echocardiogram (DSE). Normal coronary flow reserve (CFR) can be attained upon completion of a DSE at age-predicted maximum heart rate (HR) (HRmax = 220 - age)] or submaximal HR [(0.85) HRmax] or before completion (early

2. Early Use of Handgrip Exercise Associated with Dobutamine Stress Echocardiography in Women
Abstract Background Coronary artery disease (CAD) is an important cause of morbidity and mortality in women and requires early diagnosis for defining the appropriate treatment. Objective To identify the positive predictive value (PPV) and safety of the early use of handgrip exercise in pharmacological stress echocardiography using dobutamine (early-ECHO) i

3. Use of CentriMag for refractory cardiogenic shock in a puerperal woman: case report
ABSTRACT CONTEXT: Heart failure in Brazil is a major public health problem and, even with advances in treatment, it still presents high morbidity and mortality. As a treatment option, mechanical circulatory assist devices (MCADs) have greatly increased in importance over the last decade. CASE REPORT: This report concerns a case of refractory cardiogenic

4. Prevalence and risk factors for post-traumatic stress, anxiety, and depression in sepsis survivors after ICU discharge
Objective: Sepsis survivors present a wide range of sequelae; few studies have evaluated psychiatric disorders after sepsis. The objective of this study was to define the prevalence of and risk factors for anxiety, depression and post-traumatic stress disorder (PTSD) symptoms in sepsis survivors. Method: Anxiety, depression and post-traumatic stress sympto

5. Single-Dose Del Nido Cardioplegia vs. Blood Cardioplegia in Aortic Valve Replacement Surgery
Abstract Introduction: In this study, we aimed to compare Del Nido cardioplegia (DNC) with blood cardioplegia (BC) in aortic valve replacement. Methods: A two-year single-institute retrospective cohort study was accomplished. Subjects who underwent aortic valve replacement surgery were divided into two groups (DNC and BC) and outcomes were compared. Resul

9. Noradrenaline and dobutamine effects on the volume expansion with normal saline in rabbits subjected to hemorrhage
ABSTRACT PURPOSE: To evaluate the effects of dobutamine (DB), noradrenaline (NA), and their combination (NADB), on volume retention in rabbits submitted to hemorrhage. METHODS: Thirty six rabbits were randomly divided into 6 groups: SHAM, Control, Saline, DB, NA, DB+NA. All the animals, except for SHAM, were subjected to hemorrhage of 25% of the calculated

10. Clinical pharmacology of dobutamine and dopamine in preterm neonates
RESUMO A dobutamina é um estimulante seletivo β1. Agonistas de receptores β são usados para estimular a taxa e a força de contração cardíaca. O efeito cronotrópico é útil para o tratamento de arritmias e o efeito inotrópico é útil para aumentar a contratilidade do miocárdio. A dobutamina é cerca de quatro vezes mais potente que a dopamina par

11. Short-term add-on therapy with angiotensin receptor blocker for end-stage inotrope-dependent heart failure patients: B-type natriuretic peptide reduction in a randomized clinical trial
OBJECTIVE: We aimed to evaluate angiotensin receptor blocker add-on therapy in patients with low cardiac output during decompensated heart failure. METHODS: We selected patients with decompensated heart failure, low cardiac output, dobutamine dependence, and an ejection fraction <0.45 who were receiving an angiotensin-converting enzyme inhibitor. The pati

12. Echocardiographic changes during acute pulmonary edema subsequent to scorpion sting
Acute pulmonary edema (APE) occurring after scorpion sting is the leading cause of death of the victims of scorpion envenomation. The APE origin is still questioned by physicians treating these patients. Based on echocardiographic study of 20 patients with severe envenomation treated in Ouargla Hospital resuscitation ward during the last four years, the APE
