Markers of Tissue Perfusion as Predictors of Adverse Outcomes in Patients with Left Ventricular Dysfunction Undergoing Coronary Artery Bypass Surgery.

Background: Cardiac surgery patients may be exposed to tissue hypoperfusion and anaerobic metabolism.

Objective: To verify whether the biomarkers of tissue hypoperfusion have predictive value for prolonged intensive care unit (ICU) stay in patients with left ventricular dysfunction who underwent coronary artery bypass surgery.

Methods: After approval by the institution's Ethics Committee and the signing of informed consent, 87 patients with left ventricular dysfunction (ejection fraction < 50%) undergoing coronary artery bypass surgery were enrolled.

Post-COVID-19 Cardiopulmonary Symptoms: Predictors and Imaging Features in Patients after Hospital Discharge.

Background: Most of the evidence about the impact of the post-acute COVID-19 Syndrome (PACS) reports individual symptoms without correlations with related imaging.

Objectives: To evaluate cardiopulmonary symptoms, their predictors and related images in COVID-19 patients discharged from hospital.

Methods: Consecutive patients who survived COVID-19 were contacted 90 days after discharge.

In-hospital and Post-discharge Status in COVID-19 Patients With Acute Respiratory Failure Supported With Extracorporeal Membrane Oxygenation.

Few data from Latin American centers on clinical outcomes in coronavirus disease 2019 (COVID-19) patients with acute respiratory distress syndrome who required extracorporeal membrane oxygenation (ECMO) are published. Moreover, clinical and functional status after hospital discharge remains poorly explored in these patients. We evaluated in-hospital outcomes of severe COVID-19 patients who received ECMO support in two Brazilian hospitals.

Adherence to the cardiac surgery checklist decreased mortality at a teaching hospital: A retrospective cohort study.

Objective: To evaluate the impact of adherence to the cardiac surgical checklist on mortality at the teaching hospital.

Methods: A retrospective cohort study after the implementation of the cardiac surgical safety checklist in a reference hospital in Latin America. All patients undergoing coronary artery bypass surgery and/or heart valve surgery from 2013 to 2019 were analyzed.
