ObjectiveTo 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.MethodsData 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.Results83.1% 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%.ConclusionThis 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.
