Abstract
Abstract
Background
The Academic Research Consortium (ARC) proposed the new definition of high bleeding risk (HBR) criteria. It remains unknown about the prevalence and the impact of HBR on clinical outcome after acute myocardial infarction (AMI).
Purpose
To assess the prevalence and the impact of HBR on short- and long-term outcomes in patients with AMI.
Methods
Between January 2015 and January 2018, 412 patients with AMI underwent coronary angiography within 24 hours after the onset of chest pain. According to HBR criteria proposed by ARC, we divided patients into 2 groups; HBR and non-HBR group. We considered a patient HBR if the patient met at least 1 major criteria or 2 minor criteria. Major criteria included severe CKD (eGFR<30 ml/min), severe anemia (Hgb<11 g/dl), active cancer, and the use of oral anticoagulant drug. Minor criteria included high age (≥75), moderate CKD (eGFR 30–59 ml/min), moderate anemia (Hgb 11–12.9 g/dl for men and 11–11.9 g/dl for women). Kaplan-meier method was used to compare long-term outcome of HBR and non-HBR group. Major adverse cardiovascular events (MACE) were defined as all-cause death, non-fetal MI, and stroke.
Results
Patients with HBR were found in 37% of patients with AMI. In-hospital mortality (11.3% vs 4.2%, p=0.008) and MACE rate was significantly higher in HBR than non-HBR group (Figure). HBR group was associated with higher all-cause death (15.7% vs 2.5%, p<0.0001) and intracranial bleeding (4.8% vs 0.5%, p=0.02) than non-HBR group, although the incidence of non-fetal MI was comparable between two groups (7.6% vs 8.5%, p=0.76).
Conclusions
AMI patients with HBR were associated with worse outcomes both short- and long-term.

Abstract
Abstract
Background
Currently, cryoballoon ablation (CBA) has proven to be highly effective in achieving free from atrial fibrillation (AF), especially paroxysmal AF. However, the optimal freezing protocol for each patient to achieve successful pulmonary vein isolation by only CBA is still uncertain. The aim of this study was to evaluate the clinical implications of a reduction in the freezing duration (<180s) during CBA guided by the time to target temperature.
Methods
From November 2015 to August 2018, 286 consecutive paroxysmal AF patients undergoing CBA were enrolled. We compared 107 patients undergoing a tailor-made CBA procedure (Group A; August 2017-August 2018) to 179 patients with a standard CBA procedure (Group B; November 2015–July 2017). In Group A, the freezing duration was reduced to 150s when the temperature reached ≤−40°C within 40s. Furthermore, we reduced it to 120s when it reached ≤−50°C within 60s. In the other patients, the freezing time was 180s except for excessive freezing over −60°C and/or emergent situations while monitoring the esophageal temperature and for phrenic nerve injury as in Group B.
Results
The baseline clinical characteristics were similar between two groups. In Group A, 89 patients (83%) underwent CBA with a reduction in the freezing time. The rate of having reduction time in left inferior PV (LIPV) and right inferior PV (RIPV) was lower compared with left superior PV (LSPV) and right superior PV (RSPV) (respectively 17%, 29%, 56%, and 63.5%). However, for right inferior PV, in 31 patients having the reduced freezing time, none of them required touch-up ablation. Although the procedure time and frequency of touch-up ablation did not differ between the 2 groups, total freezing time for each PV was significantly shorter in Group A than Group B as shown in figure (LSPV: 164±28s vs. 216±67s; p<0.001, LIPV: 187±44s vs. 218±69s; p<0.001, RSPV: 147±31s vs. 192±51s; p<0.001, RIPV: 180±50 vs. 218±73s; p<0.001). The AF free survival rate during the follow-up period (356±167 days) was similar between the 2 groups (log-rank test, p=0.38). Furthermore, the complication rate was similar 2 groups.
The freezing time for each PV
Conclusion
The safety and efficacy of the new tailor-made CBA strategy were non-inferior to the standard procedure. This study showed that the unnecessary freezing time could be reduced in most of paroxysmal AF patients.

Abstract
Abstract
Background
Drug-eluting stent restenosis (DES-ISR) is associated with poorer outcomes than those of bare-metal stent restenosis after treatment with paclitaxel-coated balloon (PCB), and late restenosis after PCB angioplasty for DES-ISR is a residual problem. Excimer laser coronary angioplasty (ELCA) is thought to be advantageous for ISR treatment by removing neointima. However, whether the combination of ELCA and PCB angioplasty is more effective than the use of PCB only angioplasty in DES-ISR has not been studied so far.
Purpose
We evaluated the efficacy of ELCA and PCB combination therapy for DES-ISR at mid-and late-term after revascularization.
Methods
From January 2014 to March 2016, 166 DES-ISR lesions were treated with ELCA and no-ELCA prior to PCB. Two serial angiographic follow-ups were planned for the patients (at 6–12 and 18–24 months after procedure). Acute procedural and follow-up angiographic results were assessed by quantitative coronary angiography. ELCA and no-ELCA group included 74 lesions and 92 lesions, respectively.
Results
There was no significant difference between the two groups in the clinical characteristics except the prevalence of hemodialysis, the rate of first-generation DES (37.9% vs 36.8%, p=0.897), previous stent size (2.90±0.39 mm vs 2.77±0.39 mm, p=0.063), and reference vessel diameter (2.65±0.46 mm vs 2.60±0.65 mm, p=0.593). Early follow-up angiography was performed in 66 lesions (89.1%) of ELCA group, and was done in 76 lesions (82.6%) of no-ELCA group. In the ELCA group, percentage diameter stenosis (%DS) just after procedure and at 6–12 months later were significantly smaller than those of no-ELCA group. Besides, target lesion revascularization (TLR) rate at 6–12 months after procedure was tended to be lower in the ELCA group. Late follow-up angiography was performed for 93 lesions (81.6%) of the remaining 114 lesions (excluding TLR lesion), late restenosis was found 9 lesions (18.6%) in the ELCA group and 11 lesions (24.4%) in the no-ELCA group (p=0.504). Late luminal loss was similar in both groups (0.37±0.71 mm vs 0.24±0.82 mm, p=0.438), and %DS at 12–18 months after revascularization was not different between the two groups.
Changes of %DS and TLR rate
Conclusions
%DS in the ELCA group was smaller at just after procedure and the advantage was kept even after 1-year. However, late restenosis and TLR at 2-year after revascularization for DES-ISR could not be reduced by ELCA and PCB combination therapy.
