Outcome of coronary artery bypass grafting in black persons
Insights
Coronary artery bypass grafting in black patients showed acceptable mortality, but functional outcomes were disappointing, with many still experiencing angina post-surgery. This study highlights the need for improved post-operative care for this demographic.
Area of Science:
- Cardiovascular Medicine
- Health Disparities
- Surgical Outcomes
Background:
- Coronary artery disease (CAD) research in Black populations in the United States remains underrepresented.
- Understanding surgical outcomes in diverse patient groups is crucial for equitable healthcare.
- Inner-city, working-class populations present unique challenges in cardiovascular disease management.
Purpose of the Study:
- To evaluate the outcomes of coronary artery bypass grafting (CABG) in a series of Black patients.
- To assess both mortality risk and functional capacity following CABG in this specific demographic.
- To address the limited data on CAD treatment efficacy in Black Americans.
Main Methods:
- A prospective study of 73 consecutive Black patients undergoing CABG over 31 months.
- Analysis of early mortality (30-day) and late mortality (1-year) post-operation.
- Functional capacity assessment via interviews and questionnaires for a subset of 39 patients at least 6 months post-CABG.
Main Results:
- The overall 30-day mortality was 4% (3 patients), with an additional 3 deaths by the 1-year follow-up.
- While 79% of patients reported symptomatic improvement, 50% continued to experience angina.
- Postoperative employment rates were low (13%), a slight increase from pre-operative rates (one-third).
Conclusions:
- Coronary artery bypass grafting presents an acceptable mortality risk for Black patients from an urban, working-class background.
- The functional outcomes, particularly symptom relief and return to work, were disappointing in this cohort.
- Further research and targeted interventions are needed to improve long-term functional recovery and quality of life for Black patients after CABG.
Abstract:
Relatively little attention has been given to coronary artery disease in black persons in the United States. During 31 months, 73 consecutive black patients drawn from an urban working class inner city population who had undergone coronary artery bypass grafting were studied. In the total series of elective and emergency operations, 3 patients (4%) died within the first 30 days and 3 more died by the end of the first year of follow-up. Functional capacity was assessed by interviews and a questionnaire in a subset (n = 39) at least 6 months after operation. Although 79% of the patients felt that the operation had resulted in improvement of symptoms, half of them continued to report angina. Only one-third of the patients were working in the period immediately before the operation; 13% were working postoperatively. Coronary artery bypass grafting had an acceptable mortality risk in these patients, although the functional outcome was disappointing.
