STEMI receiving PCI has not been evaluated sufficiently with regard to overall mortality and non-home discharge. The aim of this study was to evaluate the association of CFS with these clinical outcomes of octogenarian patients with STEMI. Methods Study Design and Population We screened the Nagoya multicenter registry for the data of consecutive patients with STEMI who underwent primary PCI between January 2014 and December 2016 (n=1,301). The registry is an ongoing, retrospective, multicenter registry of coronary artery disease and current data include information from 5 institutions in the Tokai area, details of which have been described previously. 10 Of the

Aim: Patients undergoing percutaneous coronary intervention (PCI) who require both oral anticoagulant (OAC) and antiplatelet therapy (APT) are exposed to a serious risk of bleeding. The aim of this study was to clarify the relationship among nutritional and inflammation status and long-term bleeding in patients requiring both OACs and APT after PCI. Methods: We performed PCI in 3,718 consecutive patients between April 2011 and March 2017, 302 of whom were treated with both OACs and APT. Patients were followed for up to 3 years for bleeding events, defined as the Bleeding Academic Research Consortium (BARC) class ≥3 bleeding. We retrospectively evaluated the ability of the Geriatric Nutritiosk Index (GNRI) and high-sensitivity C-reactive protein (hs-CRP) to detect bleeding events. Results: During a median follow-up of 1,080 days, bleeding events were observed in 53 (17.5%) patients. Bleeding events were associated with a low GNRI (≤98) (hazard ratio [HR], 3.16; 95% confidence interval [CI], 1.84–5.45; p <0.0001) and hs-CRP level ≥2.5 mg/L (HR, 2.75; 95% CI, 1.61–4.78; p =0.0003). A low GNRI+high hs-CRP showed a 5.12-fold increase in the incidence of BARC class ≥3 bleeding (95% CI, 2.68–9.91; p <0.0001) compared with a normal GNRI+low hs-CRP. The addition of the GNRI and hs-CRP to the PRECISEDAPT score improved C-statistics from 0.67 to 0.71 and enhanced the net reclassification improvement (NRI) and integrated discrimination improvement (IDI) (NRI, 0.36, p <0.0001; IDI, 0.066, p <0.0001). Conclusions: The GNRI and hs-CRP were novel predictors of the long-term bleeding risk in patients requiring both OACs and APT after PCI.

BackgroundHypothyroidism has been shown to contribute to enhanced atrial arrhythmogenesis, resulting in atrial fibrillation (AF) development in animal models and clinical populations. We aimed to elucidate whether high thyroid‐stimulating hormone (TSH) levels are related to outcomes of catheter ablation of AF.Methods and ResultsOf 477 consecutive patients who underwent first‐time pulmonary vein isolation–based radiofrequency catheter ablation of AF, 456 with TSH above the lower limit of the normal range (age, 65.5±9.9 years; men, 73.9%; paroxysmal AF, 56.8%) were analyzed for this study. Atrial tachyarrhythmia recurrence for 3 years was compared across groups with hypothyroidism (n=23) and TSH quartile groups with euthyroidism (normal‐range TSH levels, n=433). Atrial tachyarrhythmia recurrence occurred in 179 patients (39%) after the first session. Patients with hypothyroidism had increased recurrence compared with patients with normal TSH levels (crude hazard ratio, 3.14 after the last session; P=0.001). When focusing on patients with normal TSH levels, recurrence‐free survivals after both the first and last sessions were significantly reduced in euthyroid patients with the highest quartile of TSH levels (quartile 4) compared with others (quartiles 1–3). Cox regression analysis identified high TSH levels as an independent predictor of atrial tachyarrhythmia recurrence after both the first (adjusted hazard ratio, 1.51; P=0.018) and last (adjusted hazard ratio, 1.86; P=0.023) sessions. The difference was more pronounced in patients with paroxysmal AF than in those with nonparoxysmal AF.ConclusionsNot only hypothyroidism but also high‐normal TSH levels may be an independent predictor of atrial tachyarrhythmia recurrence after catheter ablation of AF.

Background: No standardized tool exists for weighting bleeding risk before selecting an antithrombotic regimen in patients undergoing percutaneous coronary intervention (PCI) who require both oral anticoagulant (OAC) and antiplatelet agents. Methods: We performed PCI in 3718 consecutive patients between April 2011 and March 2017, 302 of whom were treated with both OAC and antiplatelet agents. We retrospectively evaluated the predictive performance of four major bleeding risk scores (HAS-BLED, ORBIT, PRECISE-DAPT, and PARIS score). Patients were followed for up to 3 years for bleeding events, defined as a composite of major and minor bleeding according to the Thrombolysis in Myocardial Infarction (TIMI) criteria and the Bleeding Academic Research Consortium (BARC) criteria. Results: TIMI significant bleedings (major, minor, and requiring medical attention) were seen in 90 patients (29.8%); whereas the BARC class !3 bleedings were seen in 53 patients (17.5%). Regarding TIMI significant bleedings, HAS-BLED, ORBIT, and PRECISE-DAPT scores equally categorized high-risk patients, but the PARIS score could not [high-risk versus non-high-risk: hazard ratio (HR), 1.74; 95% confidence interval (CI), 1.15-2.64; p = 0.01; HR, 1.63; 95% CI, 1.08-2.48; p = 0.02; HR, 1.62; 95% CI, 1.06-2.51; p = 0.03; HR, 1.05; 95% CI, 0.70-1.63; p = 0.79, respectively); regarding BARC class !3 bleeding, all four scores could stratify high-risk patients (high-risk versus non-high-risk: HR, 2.23; 95% CI, 1.30-3.88; p = 0.004; HR, 2.25; 95% CI, 1.31-3.96; p = 0.003; HR, 3.87; 95% CI, 2.06-7.91; p < 0.0001; HR, 1.85; 95% CI, 1.04-3.47; p = 0.04, respectively). Conclusions: In patients taking an OAC undergoing PCI, HAS-BLED, ORBIT, and PRECISE-DAPT scores predicted TIMI significant bleeding events better than the PARIS score; whereas all four scores could predict BARC class !3 bleeding events.

Objective Extracorporeal life support (ECLS) is effective for improving the survival rate of patients with refractory cardiac arrest (rCA). As little data are available regarding the impact of ECLS on a favorable neurological outcome, the predictors of a favorable neurological outcome were evaluated in this study. Methods Between January 2007 and August 2016, we retrospectively recruited patients with rCA caused by cardiac events treated with ECLS in our institute. A favorable neurological outcome was defined as a Glasgow-Pittsburgh cerebral performance category score 1 at discharge. The study endpoint was the clinical outcomes and predictors of favorable neurologic patients at discharge. Results During the study period, 67 patients with CA caused by cardiac events (acute coronary syndrome, 57 patients; idiopathic ventricular fibrillation, 10 patients) were included. Of these, 20 patients (29.9%) were classified into the favorable neurological group. No marked difference was observed in the patient characteristics between those with and without a favorable outcome except for in the time from CA to starting ECLS (ECLS initiation time). A short ECLS initiation time resulted in a favorable outcome (37.8±28.1 minutes vs. 53.6±30.7 minutes, p=0.05). The cut-off time of ECLS initiation was 46 minutes, which was prolonged by the temporary return of spontaneous circulation before ECLS [odds ratio (OR), 3.69; 95% confidence interval (CI), 1.34-10.19; p=0.01] and transfer to the angiographic room (OR, 4.07; 95% CI, 1.44-11.53, p=0.008). Conclusion The early initiation of ECLS (within 46 minutes) might be associated with a favorable neurological outcome for patients with rCA caused by cardiac events.

Background “Frailty” is associated with poor prognosis in ST-elevated myocardial infarction (STEMI). However, there is little data regarding the impact of the Canadian Study of Health and Aging Clinical Frailty Scale (CFS), a simple and semiquantitative tool for assessing frailty, on mid-term mortality in STEMI patients. Methods A total of 354 consecutive STEMI patients (mean age 69.8 ± 12.4 years; male 76.6%) who underwent percutaneous intervention between July 2014 and March 2017 were retrospectively reviewed. The study endpoint was mid-term mortality according to the CFS classification. Furthermore, in order to clarify the impact of CFS upon admission on mid-term mortality, the independent predictors of all-cause death were evaluated. Results Patients were categorized into three groups (CFS 1–3, n = 281; CFS 4–5, n = 62; and CFS 6–7, n = 11). During the study period (median 474 days), all-cause death was observed in 39 patients. After multivariate Cox regression analysis, higher CFS (adjusted hazard ratio [HR] 2.34, 95% confidence interval [CI] 1.43–3.85, p < 0.001), higher Killip score (adjusted HR 2.46, 95%CI 1.30–5.78, p = 0.002), and lower serum albumin level (adjusted HR 4.29, 95%CI 2.16–8.51, p < 0.001) were significantly associated with an increased risk of all-cause death. Conclusion In conclusion, severe frailty was associated with mid-term mortality in STEMI patients who underwent PCI.
