- BACKGROUND: We assessed antiplatelet therapy use and outcomes in patients undergoing percutaneous coronary intervention (PCI) during the ARISTOTLE trial.METHODS: Patients were categorized based on the occurrence of PCI during follow-up (median 1.8 years); PCI details and outcomes post-PCI are reported. Of the 18,201 trial participants, 316 (1.7%) underwent PCI (152 in apixaban group, 164 in warfarin group).RESULTS: inhibitor; 32% received antiplatelet agents without OAC. Post-PCI, patients assigned to apixaban versus warfarin had numerically similar rates of major bleeding (5.93 vs 6.73 events/100 patient-years; P = .95) and stroke (2.74 vs 1.84 events/100 patient-years; P = .62).CONCLUSIONS: PCI occurred infrequently during follow-up. Most patients on study drug at the time of PCI remained on study drug in the peri-PCI period; 19% continued the study drug without interruption. Antiplatelet therapy use post-PCI was variable, although most patients received DAPT. Additional data are needed to guide the use of antithrombotics in patients undergoing PCI.

- Objectives: Critical limb ischaemia (CLI) implies an increased risk of cardiovascular morbidity and mortality, and the optimal antithrombotic treatment is not established.Design, Materials, Methods: The EUCLID trial investigated the effect of monotherapy with ticagrelor versus clopidogrel in 13,885 patients with peripheral artery disease (PAD); the primary endpoint was cardiovascular death, myocardial infarction, or ischaemic stroke. Patients planned for revascularisation or amputation within 3 months, were excluded. This analysis focuses on the subgroup with CLI, defined by rest pain (58.8%), major (9.0%) or minor (32.2%) tissue loss.Results: In EUCLID, 643 patients (4.6%) had CLI at baseline. Diabetes mellitus was more common in the CLI group, while coronary disease, carotid disease, and hypertension were more common in the non-CLI group. A majority of CLI patients (62.1%) had only lower extremity PAD. In patients enrolled on the ankle brachial index (ABI) criteria, ABI was 0.55 +/- 0.21 (mean +/- SD) for those with CLI versus 0.63 +/- 0.15 for those without CLI. The primary efficacy endpoint significantly increased among patients with CLI compared with those without CLI with a rate of 8.85 versus 4.28/100 patient years (adjusted for baseline characteristics hazard ratio [HR] 1.43 [95% CI 1.16-1.76]; p = 0.0009). When acute limb ischaemia requiring hospitalisation was added to the model, significant differences remained (adjusted HR 1.38, [95% CI 1.13-1.69]; p = 0.0016). The 1 year mortality was 8.9%. A trend towards increased lower limb revascularisation among those with CLI was observed. Bleeding (TIMI major, fatal, intracranial) did not differ between those with and without CLI.Conclusions: Nearly 5% of patients enrolled in EUCLID had CLI at baseline. Milder forms of CLI dominated, a result of the trial design. Patients with CLI had a significantly higher rate of cardiovascular mortality and morbidity versus those without CLI. Further efforts are required to reduce the risk of cardiovascular events in PAD, especially in patients with CLI.

- Background: Patients with peripheral artery disease (PAD) are known to have an increased risk of ischemic cardiovascular events. However, the influence of concomitant PAD on first and subsequent recurrent ischemic events after an acute coronary syndrome (ACS) remains poorly characterized. Methods: We analyzed the combined data set from 4 randomized trials (PLATO, APPRAISE-2, TRA-CER, and TRILOGY ACS) in ACS for a follow-up length of 1 year. Using multivariable regression, we examined the association between PAD and major adverse cardiovascular events, a composite of cardiovascular death, myocardial infarction, and stroke. Among patients with a nonfatal first event, we evaluated the incidence and type of a second recurrent event. Results: A total of 4,098 of 48,094 (8.5%) post-ACS patients had a history of PAD. The unadjusted frequency of major adverse cardiovascular events was 2-fold higher in patients with PAD (14.3% vs 7.5%) over a median (25th-75th) follow-up of 353 (223-365) days with an adjusted hazard ratio of 1.63 (95% CI: 1.48-1.78; P <.001). The frequency of recurrent ischemic eventsamong those patients with a first, nonfatal event was higher among those with PAD (40.0% vs 27.7%). The relative frequency of each event type (cardiovascular death, noncardiovascular death, myocardial infarction, or stroke) within first and subsequent ischemic events was similar regardless of PAD status at baseline. Conclusions: Patients with PAD have a significantly higher risk of first and recurrent ischemic events in the post-ACS setting. These findings highlight the opportunity for improved treatments in patients with PAD who experience an ACS.
