Long-Term Clinical Outcomes for Non-ST Elevation Acute Coronary Syndrome Patients with High-Risk Angiographic Findings Undergoing Percutaneous Coronary Intervention

Sumario:OBJECTIVE: We aim to evaluate the long-term prognosis of non-ST elevation acute coronary syndrome (NSTE-ACS) patients with high-risk coronary anatomy (HRCA). BACKGROUND: Coronary disease severity is important for therapeutic decision-making and prognostication among patients presenting with NSTE-ACS. However, long-term outcome in patients undergoing percutaneous coronary intervention (PCI) with HRCA is still unknown. METHOD: NSTE-ACS patients undergoing PCI in Fuwai Hospital in 2013 were prospectively enrolled and subsequently divided into HRCA and low-risk coronary anatomy (LRCA) groups according to whether angiography complies with the HRCA definition. HRCA was defined as left main disease >50%, proximal LAD lesion >70%, or 2- to 3- vessel disease involving the LAD. Prognosis impact on 2-year and 5-year major adverse cardiovascular and cerebrovascular events (MACCE) is analyzed. RESULTS: Out of 4,984 enrolled patients with NSTE-ACS, 3,752 patients belonged to the HRCA group, while 1,232 patients belonged to the LRCA group. Compared with the LRCA group, patients in the HRCA group had worse baseline characteristics including higher age, more comorbidities, and worse angiographic findings. Patients in the HRCA group had higher incidence of unplanned revascularization (2 years: 9.7% vs. 5.1%, p < 0.001; 5 years: 15.4% vs. 10.3%, p < 0.001), 2-year MACCE (13.1% vs. 8.8%, p < 0.001), and 5-year death/MI/revascularization/stroke (23.0% vs. 18.4%, p = 0.001). Kaplan–Meier survival analysis showed similar results. After adjusting for confounding factors, HRCA is independently associated with higher risk of revascularization (2 years: HR = 1.636, 95% CI: 1.225–2.186; 5 years: HR = 1.460, 95% CI: 1.186–1.798), 2-year MACCE (HR = 1.275, 95% CI = 1.019–1.596) and 5-year death/MI/revascularization/stroke (HR = 1.183, 95% CI: 1.010–1.385). CONCLUSION: In our large cohort of Chinese patients, HRCA is an independent risk factor for long-term unplanned revascularization and MACCE.
