- Abstract
Concomitant coronary and peripheral artery disease is associated with higher periprocedural and long-term percutaneous coronary intervention (PCI) complication rates. We evaluated in-hospital and 1-year clinical outcomes of patients with low or borderline ankle-brachial indexes (ABIs) undergoing PCIs in the drug-eluting stent era. We divided 1370 SHINANO registry patients into 3 groups-low (ABI ≤ 0.9), borderline (0.9 < ABI ≤ 1.0), and normal (1.0 ≤ ABI < 1.4). During the 1-year follow-up, more PCI-related complications occurred in the low and borderline ABI groups than in the normal ABI group (7.7% vs 8.8% vs 4.0%, respectively). Low ABI patients were more likely to experience adverse clinical events (6.3% vs 3.6% vs 3.0%, respectively; log-rank P = .020 for low vs normal ABI), with a hazard ratio of 2.27 (95% confidence interval, 1.12-4.61; P = .023), compared with patients with normal ABIs. Patients with abnormal ABIs had a significantly higher incidence of PCI-related complications and a less favorable 1-year prognosis. Routine ABI measurement before PCI may help predict PCI-related complication incidence and 1-year prognosis.
