  1. Priority points and cardiac events while waiting for coronary bypass surgery.

    Article - En anglais


    To assess the risk of important cardiac events while waiting for coronary artery bypass surgery (CABG) in relation to the New Zealand priority scoring system ; to compare clinical characteristics of patients referred for CABG in New Zealand with those in Ontario, Canada ; and to compare the New Zealand priority scoring system for CABG with the previously validated Ontario urgency score.

    Design-Analysis of outcomes in a consecutive case series of patients referred for CABG.

    Setting-University hospital

    Patients-All 324 patients from Christchurch Hospital wait listed for isolated CABG between 1 January 1994 and 31 December 1995.

    Main outcome measures-Death, myocardial infarction, and unstable angina while waiting for CABG ; waiting time to surgery.


    Clinical characteristics at referral were very similar, but median waiting time was longer in New Zealand than in a large Canadian case series (212 days v 17 days).

    While waiting for elective CABG, 44% (114/257) of New Zealand patients had cardiac events : death 4% (13/257), non-fatal myocardial infarction 6% (16/257), readmission with unstable angina 34% (87/257).

    Priority scores did not predict cardiac events while waiting for CABG.

    Indeed, death or non-fatal myocardial infarction occurred in 4% (3/76) and 8% (6/76), respectively, of those with priority scores<35.

    These people are no longer eligible for publicly funded surgery in New Zealand. (...)
