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).
