Background: Left ventricular global longitudinal strain value (GLS) can predict functional capacity in patients with preserved left ventricular ejection fraction (LVEF) heart failure (HF) and to assess prognosis in reduced LVEF HF.
Objetive: Correlate GLS with parameters of Cardiopulmonary Exercise Test (CPET) and to assess if they could predict systolic HF patients that are more appropriated to be referred to heart transplantation according to CPET criteria.
Methods: Systolic HF patients with LVEF < 45%, NYHA functional class II and III, underwent prospectively CPET and echocardiography with strain analysis.
Purpose: To assess cardiopulmonary capacity, autonomic heart function, and oxygen recovery kinetics during exercise testing before and after bariatric surgery.
Methods: This is a prospective cohort study. Symptom-limited cardiopulmonary exercise testing was performed with 24 patients, 1 week before and 4 months after bariatric surgery.
Objective: Measure the systolic (SP), diastolic (DP) and pulse pressure (PP) using home blood pressure monitoring (HBPM) and correlate its values with the left ventricular mass index (LVMI).
Methods: In 2004, 127 individuals underwent HBPM in a private clinic. A total of 83 of these also underwent an echocardiographic study in a period shorter than 6 months.
Objective: To measure the serum levels of brain natriuretic peptide (BNP) in patients with chronic chagasic heart disease and in individuals with positive serology for Chagas' disease and no heart impairment, and to correlate the serum BNP levels with the degree of cardiac impairment, cardiac dimensions, presence of a pacemaker, and ejection fraction.
Methods: Serum BNP concentrations were determined by use of the Triage-BNP Test produced by BIOSITE. Serum BNP was assessed in 25 patients from the Chagas' disease outpatient clinic of the Hospital Universitario Oswaldo Cruz, who were divided into 2 groups as follows: 1) G1--comprising 13 asymptomatic patients with positive serology for Chagas' disease and no heart disease detectable on electrocardiography, chest X-ray, and echocardiography; and 2) G2--comprising 12 patients with Chagas' disease and heart impairment.
