Hemodynamic changes during heart displacement in aorta no-touch off-pump coronary artery bypass surgery: a pilot study

Abstract Objective: To evaluate the sequential changes of hemodynamic and metabolic parameters in patients who underwent aorta no-touch off-pump coronary artery bypass surgery (OPCAB). Methods: Prospective study involving twenty-seven consecutive patients who underwent aorta no-touch OPCAB. The FloTrac...

Silent Cerebral Infarctions with Reduced, Mid-Range and Preserved Ejection Fraction in Patients with Heart Failure

Arq. bras. cardiol; 111 (3), 2018
Abstract Heart failure predisposes to an increased risk of silent cerebral infarction, and data related to left ventricular ejection fraction are still limited. Our objective was to describe the clinical and echocardiographic characteristics and factors associated with silent cerebral infarction in patie...

Association of oscillatory ventilation during cardiopulmonary test to clinical and functional variables of chronic heart failure patients

Abstract Objective: The aim of this study is to characterize the presence of exercise oscillatory ventilation (EOV) and to relate it with other cardiopulmonary exercise test (CET) responses and clinical variables. Methods: Forty-six male patients (age: 53.1±13.6 years old; left ventricular ejection fr...

Association of Monocyte Count on Admission with the Angiographic Thrombus Burden in Patients with ST-Segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: The intracoronary high-thrombus burden during the primary percutaneous coronary intervention in patients with ST-elevation myocardial infarction (STEMI) can lead to poor outcomes. Monocytes have been described to play an important role in thrombotic disorders. Objectives: This stud...

Impact of a High-Intensity Training on Ventricular Function in Rats After Acute Myocardial Infarction

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: Physical exercise should be part of the treatment of post-acute myocardial infarction (AMI) patients. Objective: To evaluate the effects of two training prescription models (continuous x interval) and its impact on ventricular function in rats after AMI with normal ventricular func...

Applicability of Longitudinal Strain of Left Ventricle in Unstable Angina

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: Unstable angina (UA) is a common cause of hospital admission; risk stratification helps determine strategies for treatment. Objective: To determine the applicability of two-dimensional longitudinal strain (SL2D) for the identification of myocardial ischemia in patients with UA. Me...

Infection in Patients with Decompensated Heart Failure: In-Hospital Mortality and Outcome

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: Heart failure (HF) is a syndrome, whose advanced forms have a poor prognosis, which is aggravated by the presence of comorbidities. Objective: We assessed the impact of infection in patients with decompensated HF admitted to a tertiary university-affiliated hospital in the city of ...

Subclinical Anthracycline-Induced Cardiotoxicity in the Long - Term Follow-Up of Lymphoma Survivors: A Multi-Layer Speckle Tracking Analysis

Arq. bras. cardiol; 110 (3), 2018
Abstract Background: Anthracycline generates progressive left ventricular dysfunction associated with a poor prognosis. Objectives: The purpose of this study was to evaluate whether layer-specific strain analysis could assess the subclinical left ventricular dysfunction after exposure to anthracyclin...

Natriuretic Peptide and Clinical Evaluation in the Diagnosis of Heart Failure Hemodynamic Profile: Comparison with Tissue Doppler Echocardiography

Arq. bras. cardiol; 110 (3), 2018
Abstract Background: Physical examination and B-type natriuretic peptide (BNP) have been used to estimate hemodynamics and tailor therapy of acute decompensated heart failure (ADHF) patients. However, correlation between these parameters and left ventricular filling pressures is controversial. Objectiv...
