BACKGROUND: Distinguishing the subgroup of older, comorbid patients presenting with non-ST-elevation acute coronary syndromes (NSTEACS) who will benefit from percutaneous coronary intervention (PCI) remains challenging. Identifying risk factors for major adverse cardiac or cerebrovascular events (MACCE) post PCI may help define this cohort. The objective of this study was to describe contemporary outcomes of older patients with NSTEACS undergoing PCI and identify pre-procedural risk factors for MACCE.
METHODS: We retrospectively reviewed data for 1,875 patients aged ≥80 years entered in the Victorian Cardiac Outcomes Registry (VCOR) who underwent PCI for NSTEACS between 1 January 2013 and 31 December 2017. MACCE was a composite outcome comprising 30-day mortality, myocardial infarction, stroke, major bleeding, target lesion revascularisation or target vessel revascularisation; in-hospital cardiogenic shock or stent thrombosis; and new requirement for dialysis. Patient demographic data and pre-procedural comorbidities were compared between the groups with and without a MACCE.
RESULTS: The rate of MACCE at 30 days was 8.0% (n=150). Thirty-day (30-day) mortality was 3.0% (n=57). Pre-procedural left ventricular ejection fraction (LVEF)<45% (OR 2.32; 95% CI 1.47-3.68; p<0.001) and eGFR≤30 mL/min/1.73m2 or renal replacement therapy (OR 2.10; 95% CI 1.27-3.46; p<0.01) were independent predictors of a MACCE.
CONCLUSIONS: Older patients presenting with NSTEACS who have left ventricular systolic dysfunction or renal impairment are at increased risk of MACCE post PCI. Randomised studies are required to determine if invasive management remains beneficial for these patents compared with medical therapy.
