A model to predict survival at time of postcardiotomy intraaortic balloon pump insertion

摘要: Abstract To facilitate timely application of new forms cardiac support to patients at highest risk after cardiotomy despite conventional with the intraaortic balloon pump, an accurate prediction survival must be available time weaning from cardiopulmonary bypass. We, therefore, acquired 240 demographic, disease, and perioperative characteristics 322 (mortality rate, 48.4%) who required IABP separate bypass Four variables before within 10 minutes first attempt significantly predicted mortality by stepwise logistic regression, complete heart block as demonstrated need for temporary pacing ( p = 0.036), female sex 0.048). An equation generated model a 72.2% rate in 25% least (actual 71.6%); greatest risk, death was 73.0%, actual 74.1%. The then prospectively applied 330 pump-supported managed another institution. overall there 41.2%; 70.5% 77.1%), 75.7% 62.7%). Thus, retrospectively one institution another, this based only on data able define subgroup 2.6 2.7 times likely die similar cohorts. Consequently, devices require extraordinary can reserved those most benefit suitable potential risks inherent experimental devices.
