Association between Hemodynamic Profile at Hospital Admission and Mortality in Acute Heart Failure Patients Included in the Best Practice in Cardiology Program in Brazil.

Background: Heart failure (HF) contributes to a high burden of hospitalization, and its form of presentation is associated with disease prognosis.

Objectives: To describe the association of hemodynamic profile of acute HF patients at hospital admission, based on congestion (wet/dry) and perfusion (cold/warm), with mortality, hospital length of stay and risk of readmission.

Methods: Cohort study, with patients participating in the "Best Practice in Cardiology" program, admitted for acute HF in Brazilian public hospitals between March 2016 and December 2019, with a six-month follow-up.

A Nationwide Initiative to Improve Cardiology Quality: The Best Practice in Cardiology Program in Brazil.

Background: A Nationwide Initiative to Improve Cardiology Quality: The Best Practice in Cardiology Program in Brazil ACEI/ARB: angiotensin-converting enzyme inhibitor/angiotensin receptor blocker; LVEF: left ventricular ejection fraction; LVSD: left ventricular systolic dysfunction; AF: atrial fibrillation; PT/INR: prothrombin time/international normalized ratio.

Background: Despite significant progress in improving the quality of cardiovascular care, persistent gaps remain in terms of inconsistent adherence to guideline recommendations.

Objective: This study evaluates the effects of implementing a quality improvement program adapted from the American Heart Association's Get with the Guidelines™ initiative on adherence to guideline-directed medical therapy for acute coronary syndrome (ACS), atrial fibrillation (AF), and heart failure (HF).

Cardiovascular Statistics from the Good Practices in Cardiology Program - Data from a Brazilian Tertiary Public Hospital.

Background: The Good Practices in Cardiology Program is an initiative created by the Brazilian Society of Cardiology (SBC) to improve the quality of care of cardiovascular disease patients in Brazilian public hospitals.

Objectives: To characterize patients admitted to a tertiary public hospital with diagnosis of acute coronary syndrome (ACS) or heart failure (HF) and to evaluate performance indicators in both ACS and HF arms, with a pre-established target of 85% adherence to the SBC recommendations.

Methods: This was a descriptive cross-sectional study through data collection of patients hospitalized between May 2016 and September 2019.

Implementation of a Best Practice in Cardiology (BPC) Program Adapted from Get With The Guidelines®in Brazilian Public Hospitals: Study Design and Rationale.

Background There are substantial opportunities to improve the quality of cardiovascular care in developing countries through the implementation of a quality program. Objective To evaluate the effect of a Best Practice in Cardiology (BPC) program on performance measures and patient outcomes related to heart failure, atrial fibrillation and acute coronary syndromes in a subset of Brazilian public hospitals. Methods The Boas Práticas em Cardiologia (BPC) program was adapted from the American Heart Association's (AHA) Get With The Guidelines (GWTG) Program for use in Brazil.

Survival and Risk Factors Among Dialytic Acute Kidney Injury Patients After Cardiovascular Surgery.

Objective: Acute kidney injury (AKI) is a frequent postoperative complication after cardiovascular surgery. It has been described as a predictor of decreased survival rates, but how dialysis decreases survival when initiated on the postoperative period has yet to be determined. To analyze the survival of patients who presented postoperative AKI requiring dialysis up to 30 days after cardiovascular surgery and its risk factors is the aim of this study.

Behavior of lyophilized biological valves in a chronic animal model.

Glutaraldehyde is used in order to improve the mechanical and immunogenic properties of biological tissues, such as bovine pericardium membranes, used to manufacture heart valve bioprostheses. Lyophilization, also known as freeze-drying, preserves biological material without damage by freezing the water content and removing ice by sublimation. Through this process, dehydrated products of high quality may be obtained; also, the material may be easily handled.

In vivo study of lyophilized bioprostheses: 3 month follow-up in young sheep.

Objective: Glutaraldehyde is currently used in bovine pericardium bioprosthesis to improve mechanical and immunogenic properties. Lyophilization is a process that may decrease aldehyde residues in the glutaraldehyde treated pericardium decreasing cytotoxicity and enhancing resistance to calcification. The aim of this study is to evaluate bioprosthetic heart valves calcification in adolescent sheep and to study the potential of lyophilization as a mechanism to protect calcification.

Influence of fresh frozen plasma as a trigger factor for kidney dysfunction in cardiovascular surgery.

Objective: Kidney dysfunction is a major complication in the postoperative cardiac surgery setting. Operative risk factors for its development are cardiopulmonary bypass, anemia, antifibrinolytic drugs and blood transfusion. The objective of this study was to identify the risk factors for developing kidney dysfunction in patients undergoing cardiac surgery.

In vitro and in vivo evaluation of lyophilized bioprosthetic valve.

Freeze-drying of biological tissues allows for dry storage and gamma ray sterilization, which may improve their use as a medical prosthesis. The objective of this study was to evaluate the rehydration characteristics and hydrodynamic performance of prosthetic valves before and after lyophilization. Two size 23 bovine pericardium aortic valve prostheses from different manufacturers were evaluated in a Shelhigh (Union, NJ, USA) pulse duplicator (80 ppm, 5 L/min) before and after lyophilization.

Effect of haematocrit on pump and kidney dysfunction after myocardial revascularization.

Objective: Kidney dysfunction is a common complication after cardiac surgery. It occurs in 7 to 31% of the patients. The lowest haematocrit after cardiopulmonary bypass surgery (LHCT) has been identified as a risk factor for kidney dysfunction after cardiac surgery.

Cardiopulmonary bypass time as a risk factor for acute renal failure.

Objective: Acute renal failure following heart surgery is a major complication. The aim of this study was to evaluate if duration of cardiopulmonary bypass (CPB) is an important factor that influences kidney dysfunction.

Methods: One hundred and sixteen patients from a single center referred for heart surgery were evaluated.
