During the follow-up period, thirty-four patients died (21%). As listed
in Table 6, complete functional revascularization (p=0.013) was a
predictor of increased survival, on univariable analysis. No other
definition of complete revascularization showed effect on follow-up
mortality. Age (p=0.003), DM (p=0.028) and LVEF <50%
(p=0.028) increased the risk of follow-up mortality.
On multivariable analysis, complete functional revascularization (HR
0.47 CI95: 0,226-0,969; p=0.041) was associated with a lower risk of
follow-up mortality. Age (HR 1.04 CI95: 1.005-1.078; p=0.024) and
EF<50% (HR 2.19 CI95: 1.075-4.480; p=0.031) were independent
predictors of increased follow-up mortality (Figure 1).
During the follow-up, twenty-six patients (16%) required repeat
surgical or percutaneous revascularization. On univariable analysis,
none of the different definitions of complete revascularization had
impact on need for repeat revascularization. Dyslipidemia (p=0.016) was
a significant predictor (Table 7).
