    Coronary vasospasm after bypass surgery occurred in 8% of patients. Preoperative nifedipine or nitrate use did not prevent vasospasm, and withdrawal was not linked to increased incidence.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Vascular Medicine

    Background:

    • Coronary vasospasm is a potential complication following coronary artery bypass surgery.
    • The incidence and predictors of postoperative coronary vasospasm require further elucidation.

    Purpose of the Study:

    • To investigate the incidence of coronary vasospasm after coronary artery bypass surgery.
    • To identify potential associations between preoperative and postoperative factors and the development of coronary vasospasm.

    Main Methods:

    • Fifty patients undergoing coronary artery bypass surgery were monitored using Holter monitors.
    • Coronary vasospasm was defined as transient 2 mm ST-segment elevation.
    • Multiple stepwise regression analysis was performed on over 30 variables.

    Main Results:

    • Four patients (8%) exhibited evidence of coronary vasospasm.
    • No significant association was found between preoperative prophylaxis (nifedipine, nitrates) or other assessed variables and the development of postoperative coronary vasospasm.
    • Nifedipine or nitrate withdrawal was not associated with an increased incidence of vasospasm.

    Conclusions:

    • The incidence of coronary vasospasm post-coronary artery bypass surgery may be higher than previously recognized.
    • Current prophylactic strategies (nifedipine, nitrates) and their withdrawal patterns were not found to be associated with postoperative coronary vasospasm in this cohort.
