Coronary artery bypass surgery morbidity.

P Kuan, S B Bernstein, M H Ellestad

    Journal of the American College of Cardiology
    |June 1, 1984
    PubMed
    Summary

    Coronary artery bypass surgery patients experienced major complications, particularly those over 60 or with longer surgery times. Understanding these risks is crucial for informed patient referral and care.

    Area of Science:

    • Cardiovascular Surgery
    • Surgical Outcomes Research

    Background:

    • Coronary artery bypass surgery (CABG) is a significant intervention for coronary artery disease.
    • Assessing postoperative morbidity is essential for surgical decision-making and patient management.

    Purpose of the Study:

    • To analyze the incidence and predictors of major and minor complications following coronary artery bypass surgery.
    • To inform referring physicians about the risks associated with CABG.

    Main Methods:

    • Retrospective analysis of 365 consecutive patients undergoing CABG in 1981.
    • Categorization of complications into major (e.g., mediastinal hemorrhage, myocardial infarction) and minor (e.g., atrial fibrillation, cellulitis).

    Main Results:

    • 13% of patients experienced 52 major complications.
    • Significant predictors of major complications included age > 60 years, prolonged cardiopulmonary bypass (>150 min), prolonged aortic cross-clamp time (>100 min), >5 grafts, and diabetes mellitus.
    • Complications trended higher in women, obese patients, emergency operations, and those with ejection fraction < 30% (not statistically significant).

    Conclusions:

    • Several patient-related and procedural factors are significantly associated with major complications after CABG.
    • Physicians should consider the identified morbidity risks when referring patients for coronary artery bypass surgery.
