Clinical outcomes of following up for 12 months
There was no signifcant difference in overall MACEs and all-cause
mortality between the IABP duration ≤4 days group as compared with the
IABP duration > 4 days
group at 12-month follow up. No significant differences were also found
in the prevalence of recurrent MI, CABG, repeated PCI, or cardiac death
between the two groups (Table 4 ). The corresponding
Kaplan–Meier curves for overall, MACE-free, cardiac survival were
established (Fig 2A, 2B and 2C ). The log-rank test identified
that MACEs, all-cause mortality and cardiac death were not significantly
associated with IABP duration. Cox-regression analysis suggested that
IABP duration was not significantly correlated with the incidence of
12-month MACEs (data not shown ).
