Background: Several studies have shown the usefulness of residual Syntax score in acute coronary syndrome (ACS) patients. However, it remains uncertain whether it is also evident in ACS patients with left ventricular (LV) dysfunction.
Methods: This study was an observational study examining consecutive 311 ACS patients with LV dysfunction from January 2009 to December 2014. The residual Syntax score (rSS) was calculated at the time of post primary or primarily scheduled PCI. Patients were dichotomized into low (<8) and high rSS (≥8) groups. The primary outcome of net adverse cardiovascular events (NACE) consisted of a composite of all-cause mortality, non-fatal MI, and any revascularization at 1 year.
Results: High rSS group had more past history of cerebrovascular disease (15.5% vs. 8.0%) and chronic kidney disease (71.8% vs. 56.7%) compared to low rSS group. The incidence of NACE at 1 year was significantly higher in high rSS group than low rSS group (58.9% versus 33.2%, p<.0001). After adjustment for cofounders, high rSS was an independent predictor of the primary outcome with odds ratio of 2.00 (95%CI, 1.10-3.68; p=.024).
Conclusions: Our study suggests that rSS has similar clinical importance for patients with LV dysfunction and is associated with clinical outcome.
