New-generation metallic DES (EES/BES) were not superior to BVS in terms of angiographic LLL and clinical outcomes. (Comparison of Everolimus- and Biolimus-Eluting Stents With Everolimus-Eluting Bioresorbable Vascular Scaffold Stents [EVERBIO II]; NCT01711931).
Aims
To validate the set of clinical and biochemical criteria proposed by consensus by the Academic Research Consortium (ARC) for High Bleeding Risk (HBR) for the identification of HBR patients. These criteria were categorized into major and minor, if expected to carry in isolation, respectively, ≥4% and <4% Bleeding Academic Research Consortium (BARC) 3 or 5 bleeding risk within 1-year after percutaneous coronary intervention (PCI). High bleeding risk patients are those meeting at least 1 major or 2 minor criteria.
Methods and results
All patients undergoing PCI at Bern University Hospital, between February 2009 and September 2018 were prospectively entered into the Bern PCI Registry (NCT02241291). Age, haemoglobin, platelet count, creatinine, and use of oral anticoagulation were prospectively collected, while the remaining HBR criteria except for planned surgery were retrospectively adjudicated. A total of 16 580 participants with complete ARC-HBR criteria were included. After assigning 1 point to each major and 0.5 point to each minor criterion, we observed for every 0.5 score increase a step-wise augmentation of BARC 3 or 5 bleeding rates at 1 year ranging from 1.90% among patients fulfilling no criterion, through 4.01%, 5.98%, 7.42%, 8.60%, 12.21%, 12.29%, and 17.64%. All major and five out of six minor criteria, conferred in isolation a risk for BARC 3 or 5 bleeding at 1 year exceeding 4% at the upper limit of the 95% confidence intervals.
Conclusion
All major and the majority of minor ARC-HBR criteria identify in isolation patients at HBR.
Aims
Severe mitral regurgitation (MR) following acute myocardial infarction (MI) is associated with high mortality rates and has inconclusive recommendations in clinical guidelines. We aimed to report the international experience of patients with secondary MR following acute MI and compare the outcomes of those treated conservatively, surgically, and percutaneously.
Methods and results
Retrospective international registry of consecutive patients with at least moderate-to-severe MR following MI treated in 21 centres in North America, Europe, and the Middle East. The registry included patients treated conservatively and those having surgical mitral valve repair or replacement (SMVR) or percutaneous mitral valve repair (PMVR) using edge-to-edge repair. The primary endpoint was in-hospital mortality. A total of 471 patients were included (43% female, age 73 ± 11 years): 205 underwent interventions, of whom 106 were SMVR and 99 PMVR. Patients who underwent mitral valve intervention were in a worse clinical state (Killip class ≥3 in 60% vs. 43%, P < 0.01), but yet had lower in-hospital and 1-year mortality compared with those treated conservatively [11% vs. 27%, P < 0.01 and 16% vs. 35%, P < 0.01; adjusted hazard ratio (HR) 0.28, 95% confidence interval (CI) 0.18–0.46, P < 0.01]. Surgical mitral valve repair or replacement was performed earlier than PMVR [median of 12 days from MI date (interquartile range 5–19) vs. 19 days (10–40), P < 0.01]. The immediate procedural success did not differ between SMVR and PMVR (92% vs. 93%, P = 0.53). However, in-hospital and 1-year mortality rates were significantly higher in SMVR than in PMVR (16% vs. 6%, P = 0.03 and 31% vs. 17%, P = 0.04; adjusted HR 3.75, 95% CI 1.55–9.07, P < 0.01).
Conclusions
Early intervention may mitigate the poor prognosis associated with conservative therapy in patients with post-MI MR. Percutaneous mitral valve repair can serve as an alternative for surgery in reducing MR for high-risk patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
