- Aims To provide data guiding long-term antithrombotic therapy after coronar y arter y by-pass grafting (CABG) in patients with preoperative atrial fibrillation (AF). Methods and results From the SWEDEHEART registry, we included all patients, between January 2006 and September 2016, with preoperative AF and CHA2DS2-VASC score >2, undergoing CABG. Based on dispensed prescriptions 12 to 18 months after CABG, patients were divided in 3 groups: use of platelet inhibitors (PI) only, oral anticoagulant (OAC) only or a combination of OAC + PI. Outcomes were: Major adverse cardiac and cerebrovascular events (MACCE, [all-cause death, myocardial infarction, or stroke]), net adverse clinical events (NACE, [MACCE or bleeding]) and the individual components of NACE. Inverse probability of treatment weighting was used to adjust for the non-randomized study design. Among 2,564 patients, 1,040 (41%) were treated with PI alone, 1,064 (41%) with OAC alone, and 460 (18%) with PI + OAC. Treatment with PI alone was associated with higher risk for MACCE (adjusted HR 1.43, 95% CI 1.09-1.88), driven by higher risk for stroke and MI, compared with OAC alone. Treatment with PI + OAC, was associated with higher risk for NACE (adjusted HR 1.40, 95% CI 1.06-1.85), driven by higher risk for bleeds, compared with OAC alone. Conclusion In this real-world observational study, a high proportion of patients with AF, undergoing CABG, did not receive a long-term OAC therapy. Treatment with OAC alone was associated with a net clinical benefit, compared with PI alone or PI + OAC. (Am Heart J 2023;257:69-77.)

- IntroductionPotential benefit with potent platelet inhibition in patients with chronic coronary syndrome (CCS), undergoing percutaneous coronary intervention (PCI) has been discussed. The aim of this study was to compare a potent P2Y12 inhibition strategy using ticagrelor with clopidogrel, in CCS patients referred for coronary angiography (CA) and PCI if feasible. MethodsIn this retrospective real-world study, patients referred for outpatient CA due to suspected CCS were included. To adjust for group differences, a propensity score reflecting the probability of being treated with ticagrelor was calculated and added to the logistic regression outcome model.Results In total 1 003 patients were included in the primary analysis (577 treated with clopidogrel and 426 with ticagrelor). Among clopidogrel treated patients 132 (22.9%) experienced a bleeding complication compared with 93 (21.8%) among ticagrelor treated patients, with no significant difference between the groups (p=0.70). There was no difference in bleeding severity. Furthermore, we observed no statistically significant difference in major adverse cardiovascular event (MACE [death, stent thrombosis, myocardial infarction or stroke]), (1.2% vs 2.3%, p=0.17). A subgroup analysis restricted to patients undergoing PCI ad hoc displayed a similar pattern. Also patients undergoing CA without PCI ad hoc frequently experienced a bleeding complication, with no difference between the two treatments (21.0 % vs 17.3%, p=0.27). Propensity score adjusted analyses confirmed the results. Discussion/ConclusionIn patients with CCS referred for CA and PCI if feasible, a more potent P2Y12 inhibition strategy with ticagrelor was not associated with bleeding complications or MACE compared with clopidogrel.

- OBJECTIVES This study sought to compare interrupted and uninterrupted oral anticoagulant therapy (I-OAC vs. U-OAC) in patients on OAC undergoing percutaneous coronary intervention. BACKGROUND There is a paucity of data regarding the optimal peri-procedural management of OAC-treated patients. METHODS In the SWEDEHEART registry, all patients on OAC who were admitted acutely and underwent percutaneous coronary intervention or coronary angiography with a diagnostic procedure, from 2005 to 2017, were included. Outcomes were major adverse cardiac and cerebrovascular events (MACCE; death, myocardial infarction, or stroke) and bleeds at 120 days. Propensity score was used to adjust for the nonrandomized treatment selection. RESULTS The study included 6,485 patients: 3,322 in the I-OAC group and 3,163 in the U-OAC group. The cumulative incidence of MACCE was 8.2% (269 events) versus 8.2% (254 events) in the I-OAC and the U-OAC groups, respectively. The adjusted risk for MACCE did not differ between the groups (I-OAC vs. U-OAC hazard ratio: 0.89; 95% confidence interval: 0.71 to 1.12). Similarly, no difference was found in the risk for MACCE or bleeds (12.6% vs. 12.9%, adjusted hazard ratio: 0.87; 95% confidence interval: 0.70 to 1.07). The risk for major or minor in-hospital bleeds did not differ between the groups. However, U-OAC was associated with a significantly shorter duration of hospitalization: 4 (3 to 7) days versus 5 (3 to 8) days; p < 0.01. CONCLUSIONS I-OAC and U-OAC were associated with equivalent risk for MACCE and bleeding complications. An U-OAC strategy was associated with shorter length of hospitalization. These data support U-OAC as the preferable strategy in patients on OAC undergoing coronary intervention. (c) 2021 by the American College of Cardiology Foundation.
