Insights
The Brazilian Registry of Cardiovascular Surgeries in Adults (BYPASS) Registry data closely mirrors real-world coronary artery bypass grafting (CABG) outcomes at HCFMRP-USP. This suggests the BYPASS Registry is a valuable tool for CABG quality control.
Area of Science:
- Cardiovascular Surgery
- Health Services Research
Background:
- The Brazilian Registry of Cardiovascular Surgeries in Adults (BYPASS) Registry provides essential data on coronary artery bypass grafting (CABG) in Brazil.
- Understanding the representativeness of registry data compared to actual clinical practice is crucial for quality assessment.
Purpose of the Study:
- To compare published BYPASS Registry data with outcomes from CABG patients at Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP-USP) between 2013-2015.
- To evaluate the BYPASS Registry's suitability as a benchmark for CABG quality control.
Main Methods:
- Retrospective analysis of 173 CABG patient medical records from HCFMRP-USP.
- Comparison of HCFMRP-USP data with published BYPASS Registry data.
- Statistical analysis using the chi-square test to assess biochemical test prevalence and complications, with significance set at P < 0.05.
Main Results:
- Operative data between the BYPASS Registry and HCFMRP-USP patients showed significant similarities.
- Notable differences included a higher frequency of isolated arterial grafts (30.8% vs. 15.9%) and radial artery use (48.8% vs. 1.1%) in HCFMRP-USP patients.
Conclusions:
- The findings suggest strong concordance between the BYPASS Registry and clinical practice at HCFMRP-USP.
- The BYPASS Registry is recommended as a reference standard for quality control in coronary artery bypass grafting procedures.
Introduction:
The coronary artery bypass grafting (CABG) data provided by the Brazilian Registry of Cardiovascular Surgeries in Adults (BYPASS) Registry is a Brazilian reality.
Objective:
To carry out a comparative exercise between the BYPASS Registry published data and data from patients operated on in a randomly chosen period (2013-2015) at Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP-USP).
Methods:
This is a retrospective study reviewing 173 electronic medical records of CABG patients from the HCFMRP-USP. These data were compared with the BYPASS Registry published data. Chi-square test was used to verify the changes within the prevalence of adequate/inadequate biochemical tests before and after surgery. The sample was divided into groups consistent with cardiopulmonary bypass (CPB) time (CPB ≤ 120 minutes and CPB > 120 minutes). For the complications, prevalence by the chi-square test was adopted. Significant P-values are < 0.05.
Results:
The comparative operative data of the BYPASS Registry and the HCFMRP-USP patients were quite similar, except for the isolate use of only arterial grafts, which was more frequent on HCFMRP-USP patients (30.8% vs. 15.9%), and the use of radial artery, also more frequent on HCFMRP-USP patients (48.8% vs. 1.1%).
Conclusion:
The comparative study suggested that the BYPASS Registry should be a reference for CABG quality control.

Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
