Abstract Introduction The assessment of global myocardial work indices under baseline conditions may be useful for the clinical stratification of patients with suspected coronary obstruction. Objective To correlate the value of global myocardial work indices and the presence of significant obstructive coronary lesions. Method Cross-sectional study, with patients referred for elective coronary angiography. An echocardiogram was performed to obtain measurements to calculate the value of myocardial work and evaluated the presence or presence of significant obstructive coronary lesions at coronary […]

Abstract Background: Pulmonary artery acceleration time (PAAT) can be used as a parameter in the evaluation of pulmonary hypertension and aids left ventricular diastolic function (LVDF) analyses. Objective: To assess whether there is a correlation between PAAT and LVDF parameters in individuals with a preserved left ventricular systolic function and by sex, age, and cardiovascular risk factors. Methods: Observational cross-sectional study. One hundred nineteen patients were selected (59 women [49.6%]). The subjects underwent transthoracic echocardiography including measurements of PAAT, E […]

Abstract Introduction: Tricuspid annular plane systolic excursion and mitral annular systolic excursion are parameters used to assess the systolic function of the right ventricle and left ventricle, respectively. Little is known about its relationship with left ventricular diastolic function. Objective: To assess whether the values of mitral annular systolic excursion and tricuspid annular plane systolic excursion correlate with parameters used in the evaluation of left ventricular diastolic function. Method: Observational cross-sectional study. Two hundred nine individuals were selected, 116 women, […]

Abstract Background Transthoracic echocardiography (TTE) may play a crucial role in the evaluation of cardiac manifestations of coronavirus disease 2019 (COVID-19). Objective We aimed to report the prevalence of the main echocardiographic abnormalities of hospitalized COVID-19 patients. Methods We performed a prospective multicenter observational study in patients with COVID-19 who underwent TTE during hospitalization. Patients with pre-existing heart failure, coronary artery disease, or atrial fibrillation were categorized as having previous cardiovascular disease (CVD). Clinical and echocardiographic data about cardiac structure […]

Abstract Introduction Echocardiography is a diagnostic tool that is increasingly used in clinical practice in different medical scenarios; however, the preventive (PM) or corrective maintenance (CM) care and processes for this equipment are still poorly standardized. To describe the maintenance process currently implemented for echocardiographic equipment (ECHO) in a medium-sized laboratory in a tertiary-level public teaching hospital. The description of the process includes damage characterization and MP and MC implementation. Methods This was a descriptive and exploratory single-center observational study. […]
