Insights
The Brazilian Registry of adult Patients undergoing cArdiovaScular Surgery (BYPASS) project collected data from 1,722 patients. Early results show a 4% postoperative mortality rate, with lower rates for coronary artery bypass graft surgery.
Area of Science:
- Cardiology
- Public Health
- Surgical Outcomes
Background:
- Cardiovascular surgery is a critical intervention for numerous heart conditions.
- Understanding the profile of patients undergoing these procedures is essential for improving care and outcomes.
- Brazil, a large nation, requires a centralized registry to capture diverse patient demographics and surgical practices.
Purpose of the Study:
- To establish the Brazilian Registry of adult Patients undergoing cArdiovaScular Surgery (BYPASS) project.
- To chart the profile of adult patients undergoing cardiovascular surgery nationwide.
- To assess early data from the initial 1,722 patients in the registry.
Main Methods:
- A national, observational, prospective, and longitudinal follow-up registry.
- Data collected from 17 centers across Brazil's Southeast, Northeast, South, and Center-West regions.
- Inclusion of adult patients (≥18 years) undergoing various cardiovascular procedures including coronary artery bypass graft (CABG), valve surgery, cardiac transplantation, and mechanical circulatory support.
Main Results:
- The majority of patients (83.1%) were from the public health system (SUS).
- Common procedures included coronary artery bypass graft surgery (54.1%) and valve surgery (31.5%).
- Overall postoperative mortality up to the 7th day was 4%, with 2.6% for CABG and 4.4% for valve operations.
Conclusions:
- The BYPASS project successfully initiated a national cardiovascular surgical database.
- This database serves as a vital tool for clinical improvement and patient safety.
- It provides a foundation for future research protocols in Brazilian cardiovascular surgery.
Objective:
To report the early results of the BYPASS project - the Brazilian registrY of adult Patient undergoing cArdiovaScular Surgery - a national, observational, prospective, and longitudinal follow-up registry, aiming to chart a profile of patients undergoing cardiovascular surgery in Brazil, assessing the data harvested from the initial 1,722 patients.
Methods:
Data collection involved institutions throughout the whole country, comprising 17 centers in 4 regions: Southeast (8), Northeast (5), South (3), and Center-West (1). The study population consists of patients over 18 years of age, and the types of operations recorded were: coronary artery bypass graft (CABG), mitral valve, aortic valve (either conventional or transcatheter), surgical correction of atrial fibrillation, cardiac transplantation, mechanical circulatory support and congenital heart diseases in adults.
Results:
83.1% of patients came from the public health system (SUS), 9.6% from the supplemental (private insurance) healthcare systems; and 7.3% from private (out-of -pocket) clinic. Male patients comprised 66%, 30% were diabetics, 46% had dyslipidemia, 28% previously sustained a myocardial infarction, and 9.4% underwent prior cardiovascular surgery. Patients underwent coronary artery bypass surgery were 54.1% and 31.5% to valve surgery, either isolated or combined. The overall postoperative mortality up to the 7th postoperative day was 4%; for CABG was 2.6%, and for valve operations, 4.4%.
Conclusion:
This first report outlines the consecution of the Brazilian surgical cardiac database, intended to serve primarily as a tool for providing information for clinical improvement and patient safety and constitute a basis for production of research protocols.
