Short-Term Outcomes
Thirty-day mortality was 0% in all patient groups. There was no peri-procedural stroke, myocardial infarction (MI) or new-onset renal failure, regardless of the technique of myocardial revascularization employed (Table 3). Hospital length of stay was shorter for those patients that underwent HCR (5.7 ± 7.5 days) than for those who had CABG (7.5 ± 3.4 days) (p = 0.01), but was still longer than it was for the PCI group (2.0 ± 2.2 days) (p < 0.0001).
There was no significant difference in residual SYNTAX score between those patients who had HCR (4.5 ± 4.4) and those who underwent CABG (5.2 ± 4.7) (p = 0.31). However, despite the HCR cohort having a higher SYNTAX score at baseline than those patients who underwent multi-vessel PCI, the residual SYNTAX score was significantly lower after HCR than it was after PCI (4.5 ± 4.4 vs. 7.1 ± 6.5, respectively, p = 0.001) (Table 3).
