Oral anticoagulant use and outcomes in Asian patients with atrial fibrillation in the GLORIA-AF Registry

Abstract Background Ethnic differences in the management and outcomes of patients with atrial fibrillation (AF) have been shown in previous studies, but available data is still limited, although urgently needed. Purpose to analyse oral anticoagulant (OAC) prescription, OAC discontinuation, and long-term risk of major outcomes in Asian patients with AF, using data from a global prospective cohort study. Methods Using data from the GLORIA-AF Registry Phase II and III, we analysed patients according to their self-reported ethnicity (Asian vs. Non-Asian), and according to Asian ethnic subgroup (i.e. Chinese, Japanese, Korean and other Asian). Odds of OAC prescription were analysed through multivariable logistic regression, while the risk of OAC discontinuation and adverse outcomes were analysed through multivariable Cox-regression model. Primary outcome of this analysis was defined as the composite of all-cause death and major adverse cardiovascular events (MACE). Results 34,421 AF patients were included (70.0±10.5 years, 45.1% females, 6,900 (20.0%) Asian). Compared to Non-Asian subjects, prescription of OAC and non-vitamin K antagonist oral anticoagulant (NOAC) was lower in Asian subjects (Odds Ratio [OR] and 95% Confidence Intervals (CI): 0.23 [0.22-0.25] and 0.66 [0.61-0.71], respectively; Figure 1), but higher in the Japanese subgroup. Asian ethnicity was also associated with OAC discontinuation (Hazard Ratio [HR] and [95%CI]: 1.79 [1.67-1.92]), and lower risk of the primary composite outcome (HR [95%CI]: 0.86 [0.76-0.96]; Figure 2). Among the secondary outcomes, Asian patients had also higher risk of thromboembolism and intracranial haemorrhage, and lower risk of major bleeding events. Conclusions In this large, contemporary cohort of patients with AF, Asian subjects received suboptimal management of thromboembolic risk, and showed a peculiar long-term risk of adverse outcomes. Integrated and appropriate treatment of these patients is crucial to improve their prognosis.Figure 1Figure 2

Sex differences in long-term outcomes among hospitalized heart failure patients across the spectrum of ejection fraction: findings from the Get with the guidelines - heart failure registry

Abstract Background Sex differences in 5-year outcomes across heart failure (HF) ejection fraction (EF) subtypes are not well known. Purpose To assess the interaction between sex and EF for risk of long-term adverse outcomes after hospitalization with HF. Methods Patients from American Heart Association’s Get With The Guidelines – Heart Failure registry enrolled between 1/1/2006 – 12/31/2014 with age ≥ 65 years with available 5-year follow-up data, ascertained through linkage with Medicare fee-for-service Part A administrative claims, were included. HF subtypes included HF with reduced EF (HFrEF) with EF ≤ 40%, HF with mildly reduced EF (HFmrEF) with EF 41-49%, and HF with preserved EF (HFpEF) with EF ≥ 50%. Sex differences in 5-year all-cause mortality and readmission for each HF subtype were assessed using unadjusted cumulative incidence methods and adjusted Cox models. Median survival across HF subtypes was compared to median survival of U.S. adults. Results 155,670 patients (mean age 81 years, 53.4% females) were included. Male patients were younger and had a higher prevalence of prior myocardial infarction or coronary artery bypass graft surgery and were more likely to have HFrEF, while women were more likely to have history of hypertension and HFpEF. The median post-hospitalization survival of patients with HF was substantially lower than the age- and sex-specific U.S. life expectancy across each HF subtype (Figure 1).Patients with HF had high 5-year mortality rates (HFrEF male: 81.3%, female: 78.4%; HFpEF male: 80.5% vs female 79.5%). In adjusted analysis, female (vs. male) patients had a significantly lower 5-year mortality risk (HR [95%CI]: 0.89 [0.87 – 0.90], p<0.01) and a higher 5-year readmission risk (all-cause: 1.03 [1.02 – 1.04]), CV: 1.05 [1.04 – 1.07]), HF: 1.06 [1.04 – 1.08], p<0.01 for each). HF subtype modified the association between sex and 5-year outcomes (pinteraction <0.05 for mortality and CV and HF readmission), with the greatest risk reduction of mortality for female vs. male patients with HFrEF and the greatest risk increase of readmission (CV and HF) among female vs. male patients with HFmrEF and HFpEF (Figure 2). Conclusion Among patients with HF, the overall survival post-HF hospitalization is very low for each HF subtype. Female patients have a lower 5-year mortality risk but a higher risk of HF or CV readmission regardless of EF.Figure 1Figure 2

Abstract 17210: Re-Defining Antibody Mediated Rejection With Donor-Specific Antibodies and Graft Dysfunction, on Behalf of the GRAfT Investigators

Introduction: Heart transplant recipients with donor-specific antibodies (DSA) have increased risk for antibody-mediated rejection (AMR). However, many patients with graft dysfunction and DSA do not show AMR by endomyocardial biopsy (EMB). Hypothesis: We hypothesized that, similar to EMB-defined AMR, AMR defined as DSA presence + graft dysfunction on echocardiography is associated with 1) graft injury via elevated donor-derived cell-free DNA (dd-cfDNA) and 2) risk for long-term adverse outcomes. Methods: Adult heart transplant recipients from the Genomic Research Alliance for Transplantation (GRAfT, a prospective, multicenter study from 2015 to 2020) had DSA, echocardiogram, and dd-cfDNA evaluated at time of EMB. AMR was defined by EMB (pAMR ≥ 1), DSA/EF (DSA presence + LVEF drop by ≥ 10% to an LVEF ≤50%), or a composite of EMB or DSA/EF criteria. The composite long-term endpoint was death or long-term EF reduction ≤ 50% for >90 days. Results: 216 patients (29% Female, 39% Black race, mean age 52 ± 12 years) had 1489 EMB, 1959 DSA, 1821 echocardiogram, and 1190 dd-cfDNA evaluations. DSA were present in 71 patients (34%), predominantly class II (69%). AMR was detected by EMB in 16 subjects and by DSA/EF in 10 subjects. Median %dd-cfDNA for subjects with AMR by EMB was 0.63% (IQR 0.23-2.0), by DSA/EF was 0.40% (IQR 0.36-1.24), and for controls was 0.01% (IQR 0.001-0.10). There were 18 deaths and 10 subjects with long term EF reduction. As compared to controls, development of each AMR definition was associated with the composite long-term endpoint: AMR by EMB, HR=3.6, P =0.010; AMR by DSA/EF, HR=23.4, P <0.0001; composite AMR, HR=7.6, P <0.0001, Figure. Conclusions: Heart transplant recipients with EMB and EF/DSA AMR have similar evidence of graft injury via dd-cfDNA as well as risk of long-term adverse outcomes, as compared to those without AMR. Therefore, a composite definition of AMR, including EMB or DSA/EF may better allow for identification of patients at risk for graft failure.

The prognostic nutrition index is a predictor for long-term outcomes after revascularization in adult moyamoya disease.

The prognostic nutrition index (PNI) has been associated with the prognosis of various medical disorders. This study aimed to explore the correlation between PNI and the long-term outcomes of adult patients afflicted with moyamoya disease (MMD). This prospective study initially employed 138 adult patients diagnosed with MMD. After excluding 15 patients who did not meet the criteria, a total of 123 patients were included. Participants were divided into three groups based on the tertile of change in the PNI score. Statistical analysis compared clinical information and lab tests among the groups. The study was conducted between July 1 and December 31, 2019. After adjusting for multiple variables, patients in the upper two tertiles (tertiles 2-3) exhibited a significantly lower risk of adverse long-term outcomes compared to those in the lowest tertile (tertile 1) (OR, 0.089; 95% CI, 0.009-0.895; P = 0.040). Furthermore, adding PNI tertile to traditional risk factors substantially improved predicting adverse long-term outcomes (net reclassification improvement: 98.03%, P = 0.000; integrated discrimination improvement: 4.65%, P = 0.030). However, there was no statistically significant difference between the first PNI tertile (tertile 1) and the upper two tertiles (tertiles 2-3) in the Kaplan-Meier curve of stroke incidence (log-rank test, P = 0.244). A higher PNI level was significantly associated with a reduced risk of unfavorable long-term outcomes. Nevertheless, the PNI score did not predict stroke recurrence during extended follow-up. This study provides insights into a potential predictor of adverse long-term outcomes after revascularization in MMD patients. ChiCTR2000031412.

Oesophageal stasis is a risk factor for chronic lung allograft dysfunction and allograft failure in lung transplant recipients.

Morbidity and mortality in lung transplant recipients are often triggered by recurrent aspiration events, potentiated by oesophageal and gastric disorders. Previous small studies have shown conflicting associations between oesophageal function and the development of chronic lung allograft dysfunction (CLAD). Herein, we sought to investigate the relationship between oesophageal motility disorders and long-term outcomes in a large retrospective cohort of lung transplant recipients. All lung transplant recipients at the Toronto Lung Transplant Program from 2012 to 2018 with available oesophageal manometry testing within the first 7 months post-transplant were included in this study. Patients were categorised according to the Chicago Classification of oesophageal disorders (v3.0). Associations between oesophageal motility disorders with the development of CLAD and allograft failure (defined as death or re-transplantation) were assessed. Of 487 patients, 57 (12%) had oesophagogastric junction outflow obstruction (OGJOO) and 47 (10%) had a disorder of peristalsis (eight major, 39 minor). In a multivariable analysis, OGJOO was associated with an increased risk of CLAD (HR 1.71, 95% CI 1.15-2.55, p=0.008) and allograft failure (HR 1.69, 95% CI 1.13-2.53, p=0.01). Major disorders of peristalsis were associated with an increased risk of CLAD (HR 1.55, 95% CI 1.01-2.37, p=0.04) and allograft failure (HR 3.33, 95% CI 1.53-7.25, p=0.002). Minor disorders of peristalsis were not significantly associated with CLAD or allograft failure. Lung transplant recipients with oesophageal stasis characterised by OGJOO or major disorders of peristalsis were at an increased risk of adverse long-term outcomes. These findings will help with risk stratification of lung transplant recipients and personalisation of treatment for aspiration prevention.

Coronary artery bypass grafting using bilateral internal thoracic arteries in patients with diabetes and obesity: A systematic review and meta-analysis

BackgroundPatients with diabetes and obesity are at higher risk of adverse long-term outcomes following coronary artery bypass grafting. The use of bilateral internal thoracic arteries (BITA) can potentially offer survival benefit in higherrisk patientscompared to single internal thoracic artery (SITA), but BITAisnotroutinelyused due tolack of clear evidence of efficacy andconcerns over sternal wound complications. MethodsMedline, Embase and the Cochrane Library were searched forstudies comparing the efficacy and safety of BITA and SITA grafting in patients with diabetes and obesity. Meta-analysis of mortality and sternal wound complications was performed. ResultsWe identified eight observational and ten propensity matched studies, and one RCT, comparing BITA and SITA which included patients with diabetes (n = 19,589); two propensity matched studies and one RCT which included patients with obesity (n = 6,972); mean follow up was 10.5 and 11.3 years respectively. Meta-analysis demonstrated a mortality reduction for BITA compared to SITA in patients with diabetes (risk ratio [RR] 0.79; 95% confidence interval [CI] 0.70–0.90; p = 0.0003). In patients with obesity there was a non-significant reduction in mortality in the BITA group (RR 0.73, 95% CI 0.47–1.12; p = 0.15). There was a significantly higher rate of sternal wound complications following BITA observed in patients with diabetes (RR 1.53, 95% CI 1.23–1.90; p = 0.0001) and obesity (RR 2.24, 95% CI 1.63–3.07; p < 0.00001). ConclusionsBITA is associated with better long-term survival in patients with diabetes. The effects of BITA grafting in patients with obesity are uncertain. BITA is associated with higher rates of sternal wound complications compared to SITA in both patients with diabetes and obesity.

Early life corticosteroid overexposure: Epigenetic and fetal origins of adult diseases.

The relationship between events occurring during intrauterine development and later-life predisposition to long-term disease, has been described. The fetus responds to excess intrauterine exposure to high levels of corticosteroids, modifying their physiological development and stopping their growth. Fetal exposure to elevated levels of either endogenous (alterations in fetal hypothalamic-pituitary-adrenal axis) or synthetic corticosteroids, is one model of early-life adversity; to developing adult disease. At the molecular level, there are transcriptional changes in metabolic and growth pathways. Epigenetic mechanisms participate in transgenerational inheritance, not genomic. Exposures that change 11β-hydroxysteroid dehydrogenase type 2 enzyme methylation status in the placenta can result in transcriptional repression of the gene, causing the fetus to be exposed to higher levels of cortisol. More precise diagnosis and management of antenatal corticosteroids for preterm birth, would potentially decrease the risk of long-term adverse outcomes. More studies are needed to understand the potential roles of factors to alter fetal corticosteroid exposure. Long-term infant follow-up is required to determine whether methylation changes in placenta may represent useful biomarkers of later disease risk. This review, summarize recent advances in the programming of fetal effects of corticosteroid exposure, the role of corticosteroids in epigenetic gene regulation of placental 11β-hydroxysteroid dehydrogenase type 2 enzyme expression and transgenerational effects.

Predicting Long-term Outcomes in Deceased Donor Kidney Transplant Recipients Using Three Short-term Graft Characteristics.

Delayed graft function (DGF) in kidney transplant recipients is used to determine graft prognosis, make organ utilization decisions, and as an important end-point in clinical trials. However, DGF is not an ideal measure of graft function. We aimed to develop and validate a model that provides incremental risk assessment for inferior patient and graft outcomes. We included adult kidney-only deceased donor transplant recipients from 1996 to 2016. In addition to DGF, two short-term measures were used to assess risk: renal function recovery<100% (attaining half the donor's eGFR) and recipient's 90-day eGFR<30. Recipients were at no-, low-, moderate- or high-risk if they met zero, one, two, or all criteria, respectively. Cox proportional hazards models were used to assess the independent relationship between the exposure and death-censored graft failure (DCGF) and mortality. Of the 792 eligible recipients, 24.5% experienced DGF, 40.5% had renal function recovery<100% and 6.9% had eGFR<30. Over a median follow-up of 7.3 years, the rate of DCGF was 18.7% and mortality was 25.1%. When compared with recipients at no risk, those at low-, moderate- and high-risk were noted to have an incremental increase in risk of DCGF (aHR=1.53, 95%CI:1.03-2.27; aHR=2.84, 95%CI:1.68-4.79; aHR=15.46, 95%CI:8.04-29.71) and mortality (aHR=1.16, 95%CI:0.84-1.58; aHR=1.85, 95%CI:1.13-3.07; aHR=2.66 (95%CI:1.19-5.97). When using a hierarchical approach, each additional exposure predicted the risk of DCGF better than DGF alone and 100 random bootstrap replications supported the internal validity of the risk model. In an external validation cohort deemed to be at lower risk for DCGF, similar non-significant trends were noted. We propose a risk model that provides an incremental assessment of recipients at higher risk of adverse long-term outcomes than DGF alone. This can help advance the field of risk assessment in transplantation and inform therapeutic decision-making in patients at the highest spectrum of inferior outcomes.

Early vs. Late Readmission following Percutaneous Coronary Intervention: Predictors and Impact on Long-Term Outcomes.

Readmissions within 1 year after percutaneous coronary intervention (PCI) are common (18.6-50.4% in international series) and a burden to patients and health services, however their long-term implications are not well characterised. We compared predictors of 30-day (early) and 31-day to 1-year (late) unplanned readmission and the impact of unplanned readmission on long-term clinical outcomes post-PCI. Patients enrolled in the GenesisCare Cardiovascular Outcomes Registry (GCOR-PCI) from 2008 to 2020 were included in the study. Multivariate logistic regression analysis was performed to identify predictors of early and late unplanned readmission. A Cox proportion hazards regression model was used to explore the impact of any unplanned readmission during the first year post-PCI on the clinical outcomes at 3 years. Finally, patients with early and late unplanned readmission were compared to determine which group was at the highest risk of adverse long-term outcomes. The study comprised 16,911 consecutively enrolled patients who underwent PCI between 2009-2020. Of these, 1422 patients (8.5%) experienced unplanned readmission within 1-year post-PCI. Overall, the mean age was 68.9 ± 10.5 years, 76.4% were male and 45.9% presented with acute coronary syndromes. Predictors of unplanned readmission included increasing age, female gender, previous CABG, renal impairment and PCI for acute coronary syndromes. Unplanned readmission within 1 year of PCI was associated with an increased risk of MACE (adjusted HR 1.84 (1.42-2.37), p < 0.001) and death over a 3-year follow-up (adjusted HR 1.864 (1.34-2.59), p < 0.001) compared with those without readmission within 1-year post-PCI. Late compared with early unplanned readmission within the first year of PCI was more frequently associated with subsequent unplanned readmission, MACE and death between 1 and 3 years post-PCI. Unplanned readmissions in the first year following PCI, particularly those occurring more than 30 days after discharge, were associated with a significantly higher risk of adverse outcomes, such as MACE and death at 3 years. Strategies to identify patients at high risk of readmission and interventions to reduce their greater risk of adverse events should be implemented post-PCI.

Clinical outcomes of patients with rheumatoid arthritis who underwent percutaneous coronary intervention: A Korean nationwide cohort study.

Rheumatoid arthritis (RA) increases the risk of cardiovascular disease. This study aimed to investigate the short-and long-term prognosis of patients with and without RA who underwent percutaneous coronary intervention (PCI). The Korean National Health Insurance Service claims database was used to extract data on 236,134 patients (34,493 with RA and 201,641 without RA) who underwent PCI between 2008 and 2019. The primary outcome was major adverse cardiovascular events (MACE), including all-cause mortality, myocardial infarction, stroke, transient ischemic attack, or coronary revascularization with short-term (30-day) and long-term outcomes. The secondary outcomes were the individual components of MACE. During a 10-year follow-up, patients with RA showed a shorter median survival time from MACE than their counterparts (with RA: 4.29 years vs. without RA: 6.10 years). RA was significantly associated with an increased risk of MACEs in long-term outcomes (hazard ratio (HR) 1.07, 95% confidence intervals (CI) 1.06-1.09, p<0.001), but not with short-term outcomes (HR 1.02, 95% CI 0.99-1.06, p = 0.222). RA was an independent predictor of an increased risk of all the MACE components. In patients who underwent PCI, RA did not increase the risk of short-term cardiovascular outcomes but increased the risk of long-term adverse outcomes.

Early intervention in psoriasis: Where do we go from here?

Patients with psoriasis often have comorbidities and are at increased risk of developing several complications compared with the general population. Knowledge on the role of immune mediators and systemic inflammation in psoriasis has led to the hypothesis that early intervention with systemic therapy has the potential to modify the course of the disease and reduce the risk of long-term adverse outcomes. In this article, we address some potential issues that need to be considered before early intervention can be implemented routinely. The first is determining what constitutes "early" intervention for psoriasis. A second point is whether the intervention should be considered for patients with early disease or for selected subsets based on risk stratification. A third important consideration is defining success for early intervention. Finally, adoption of early and effective intervention should be based on high-level evidence. Ideally, randomized trials would be the best strategy to compare early vs. late systemic treatment in patients with psoriasis, probably using the frequency of long-term outcomes as primary endpoint, with cutaneous and pharmacoeconomic outcomes assessed secondarily.

Abstract 13385: Long Term Outcomes in Catheter Ablation of Atrial Fibrillation Compared to Medical Therapy

Introduction: The long-term effects of catheter ablation (CA) compared to medical therapy on cardiovascular outcomes for atrial fibrillation (AF) remain undetermined. We examined the outcomes associated with CA compared to rate or rhythm control therapy in a population cohort with AF. Methods: Using Alberta administrative data, patients with AF as the primary diagnosis during hospitalization or emergency department/physician visit were included between 2008-2018. Based on therapy received, patients were assigned to CA, rate (digoxin, calcium channel or beta blocker) or rhythm control (amiodarone, sotalol, flecainide, propafenone, dronedarone). If treatment changed over time, the patient was censored in the prior treatment arm and assigned to the new arm. The association of treatment (included as time-varying covariate) with the primary composite outcome of death, hospitalization for heart failure or stroke was examined using multivariable Cox models after adjusting for age, sex, comorbidities and baseline medications. Secondary outcomes included cardiovascular hospitalizations, and individual components of the composite. Results: There were 2,149 (4.0%) patients treated with CA and 51,315 with medical treatment (rate : 41,948, (81.5%) rhythm: 9,367 (18.2%). During a median follow-up of 4.2 years, CA for AF was associated with a lower crude incidence of the composite outcome (rate per 100 person-years was 3.3 for CA, 9.5 for rate control, and 6.3 for rhythm control). In multivariate analysis, compared to CA, both rate (adjusted hazard ratio (aHR) 1.55, 95% confidence interval (CI), 1.44 to 1.68) and rhythm control (aHR 1.37; 95% CI 1.27 to 1.49) were associated with a higher risk of the primary composite outcome.(Figure) Secondary outcomes are shown in the Figure. Conclusions: Only a small percentage of patients with AF undergo CA. Patients selected for CA have a lower risk of long-term adverse outcomes compared to medical therapy in patients with AF.

Evaluating the Effectiveness of a Training Program for Treatment Foster Parents in an Urban Community

Treatment foster care (TFC) provides critical mental health supports for youth with emotional, behavioral, and social difficulties who are at risk for adverse long-term outcomes. Existing evidence-based models of TFC are effective, yet resource-intensive, and they have relied primarily on evidence of implementation effectiveness with samples of non-minority parents. Recent research highlights the efficacy of an emerging, socially acceptable model that integrates existing evidence-based practices with usual care. This study applied the new model, Together Facing the Challenge (TFTC), within an urban TFC program. Trained TFC program staff delivered the TFTC training to foster parents in two cohorts. Foster parents reported child problem and prosocial behaviors pre-, mid-, and post-training, as well as 1, 3, and 12 months after the training. Results indicated that foster parents demonstrated an increase in knowledge of TFTC skills following the training and were satisfied with the training. Child problem behaviors significantly decreased over time. There were no significant changes in prosocial behavior over time. Implications of this study include the replication and extension of the use of TFTC, an evidence-based and resource-efficient intervention, to reduce problem behaviors of TFC children in urban settings.

Mental health in adults born preterm with very low birth weight at 14 and 26 years of age assessed by the Strengths and Difficulties Questionnaire.

Very low birth weight (VLBW: <1500 g) is associated with risk of adverse long-term outcomes, including mental health problems. We assessed whether self-reported mental health differed between young adults born preterm with VLBW and term-born controls. We also examined changes in mental health from 14 to 26 years. In a prospective cohort study, 61 VLBW and 88 control participants completed the Strengths and Difficulties Questionnaire at 26 years. Group differences were analysed by linear regression with adjustment for sex and parental socioeconomic status. Longitudinal changes from 14 to 26 years were analysed using linear mixed model. Mean total difficulties score was 1.9 (95% CI: 0.5 to 3.5) higher in the VLBW than in the control group. Internalising and its subscale emotional problems as well as externalising and its subscale hyperactivity/inattention symptoms were higher in the VLBW group. From 14 to 26 years, changes in emotional symptoms, peer relationship problems, externalising problems, hyperactivity/inattention, and prosocial behaviour differed between the groups. At 26 years, VLBW participants had more self-reported mental health difficulties than controls. Emotional symptoms increased from 14 to 26 years in the VLBW group, whereas hyperactivity and inattention did not decrease with age as it did in the control group.

Higher risk of adverse outcomes and need for pacemaker among patients undergoing radiofrequency ablation due to ectopic atrial tachycardia – a nationwide registry-based Danish study

Abstract Introduction Atrioventricular nodal reentry tachycardia (AVNRT), Wolf-Parkinson-White syndrome (WPW), and Ectopic atrial tachycardia (EAT) are common arrhythmias and associated with lower quality of life. The use of radiofrequency ablation (RFA) treatment has increased over time, however long-term risk of adverse outcomes after RFA in patients with AVNRT, WPW, or EAT is unknown. Purpose To examine the long-term risk of adverse outcomes and need for pacemaker after RFA in AVNRT-, WPW-, and EAT-patients. Methods Using Danish nationwide registries, patients of 18 years or older who underwent RFA for AVNRT, WPW, or EAT between January 1st 2001 and January 1st 2019 were included. Comorbidities and use of antiarrhythmic drugs were analyzed. The cumulative incidences of pacemaker implantation and a combined endpoint of death, thromboembolism (TE), ischemic heart disease (IHD), and heart failure (HF) were estimated at 5-year follow-up using the Aalen-Johansen estimator, taking death as competing risk into account. Results A total of 10.439 patients were enrolled in the study. 6187 patients were treated for AVNRT. The median age was 55 [42, 65] and 40% were male. The WPW group consisted of 2872 patients. The median age was 42 [29, 55] and 61% were male. The EAT group consisted of 1380 patients. The median age was 57 [44, 67] and 47% were male. The comorbidity burden was generelly higher in EAT patients especially regarding heart failure and hypertension. Use of antiarrhythmic drugs was higher in EAT patients compared to patients with AVNRT and WPW. Figure 1 shows the cumulative incidence of a composite endpoint of death, TE, IHD, and HF 5 years after RFA treatment and depicts that the cumulative incidence was 22.1%, 13.9% and 8.2% for EAT-, AVNRT- and WPW-patients respectively. Figure 2 shows the 5-year cumulative incidence of pacemaker implantations which was 9.0%, 4.4% and 3.1% for EAT-, AVNRT- and WPW-patients respectively. Conclusion At long-term follow-up patients with RFA for EAT have a higher risk of death, TE, IHD and HF compared to patients treated for AVNRT and WPW. EAT patients also have the highest risk of pacemaker implantation. Funding Acknowledgement Type of funding sources: None.

Development of a new scoring method in the neurofunctional assessment of preterm infants

Infants born preterm are at high risk of presenting neurodevelopmental delay. The Neurofunctional Assessment (NFA) describes infants’ neurodevelopment through the evaluation of six different domains. This study aimed to evaluate how, in a cohort of preterm infants, each NFA domain assessed at 3 months of corrected age (CA) was associated with neurodevelopment at 2 years of CA using the Griffiths Mental Developmental Scales Extended Revised (GMDS-ER). In addition, by introducing the NFA complexity score (CS), the study aimed to define a threshold that can help clinicians discriminate infants at higher risk of later neurodevelopmental delay. We conducted an observational, longitudinal study including 211 preterm infants. At 3 months of CA, infants who had normal scores in each domain showed a significantly higher GMDS-ER global quotient (GQ) at 2 years of CA. In addition, linear model results showed a significant negative relationship between the NFA CS and 2-year GMDS-ER GQ (estimate: − 0.27; 95% CI − 0.35, − 0.20; p value < 0.001). Each 10-point increase in the NFA CS was associated with an average 2.7-point decrease in the GMDS GQ. These results highlight how the NFA domains and NFA CS are compelling instruments for the early identification of children at risk for long-term adverse outcomes.

Elevated Admission Cardiac Troponin I Predicts Adverse Outcomes of Acute Type B Aortic Dissection after Endovascular Treatment.

BackgroundThere is a lack of evidence about the predictive role of serum cardiac troponin I (cTnI) on the long-term adverse outcomes of acute type B aortic dissection (aTBAD) patients after thoracic endovascular aortic repair (TEVAR). In this study, we identified whether cTnI was an independent risk factor of 5-year adverse outcomes for aTBAD patients after TEVAR.MethodsWe reviewed consecutive aTBAD patients without previous heart disease who were admitted for TEVAR. The total study population was divided into the cTnI(+) group (≥0.03 ng/mL) and the cTnI(−) group (<0.03 ng/mL) according to the time-dependent receiver operating characteristic curve analysis. The differences in clinical characteristics, operative details and clinical outcomes were compared between the two groups.ResultsThere was no difference in age and male prevalence between the two groups. Compared with the cTnI(−) group, the incidence of chronic kidney disease was higher in patients with cTnI ≥0.03 ng/mL. In addition, the cTnI(+) group presented with more frequent premature beats and non-myocardial-infarction ST-T segment changes. In terms of laboratory examinations, white blood cell counts, neutrophil counts, serum D-dimer and serum fibrin degradation products showed an increase in the cTnI(+) group, while lymphocyte and platelet counts showed a decrease in these patients. Patients with elevated cTnI suffered from increased risks of 5-year aortic-related adverse events (hazard ratio, HR = 1.822, 95% confidence interval, CI: 1.094–3.035; p = 0.021) and all-cause mortality (HR = 4.009, 95% CI: 2.175–7.388; p < 0.001).ConclusionAmong aTBAD patients without previous heart disease, preoperative elevated cTnI identified patients at an increased risk of long-term adverse outcomes after TEVAR.

91-OR: Association between Complexity of Glucose Time Series and All-Cause Mortality in Patients with Type 2 Diabetes Mellitus: A Prospective Cohort study

Background: Continuous glucose monitoring (CGM) can comprehensively reflect the dynamic changes of blood glucose varying with time. CGM data with more patterns of change represents glucose time series with higher complexity. However, the relationship between complexity of glucose dynamics and clinical outcomes of diabetes remains unknown. Objective: To investigate the association between complexity of glucose time series, quantified by multiscale entropy (MSE) analysis, and all-cause mortality in patients with type 2 diabetes mellitus (T2DM) in a prospective cohort study. Methods: Data of 6,001 adult inpatients with T2DM included from January 2005 to December 2015 in a single center was analyzed. Complexity of glucose index (CGI) of glucose time series from CGM was measured by MSE analysis at baseline. Participants were stratified by the tertiles of CGI: &amp;lt; 2.15,2.15∼2.99, and ≥ 3.00. Cox proportional hazards regression models were used to estimate the association between different levels of CGI and the risks of all-cause mortality. Results: During a median follow-up of 6.8 years, 799 deaths were identified. Multivariate Cox regression analysis revealed that the increase of CGI was associated with a lower risk of all-cause mortality (P for trend = 0.021) . The multivariable-adjusted HRs for all-cause mortality at different CGI levels [&amp;lt; 2.15 (reference group) , 2.15∼2.99, and ≥ 3.00] were 1.00, 0.49 (95%CI 0.30-0.79) , and 0.56 (95%CI 0.36-0.87) in patients with HbA1c &amp;lt; 7.0% (P for trend = 0.015) , while the association was nonsignificant in those with HbA1c ≥ 7.0%. And a significant interaction between HbA1c and CGI (P for interaction = 0.032) was noted in the study. Conclusion: Lower CGI is associated with an increased risk of all-cause mortality in T2DM achieving HbA1c target, which suggests that the improvement of CGI may further reduce the risk of long-term adverse outcomes in T2DM at an early stage or with good glycemic control.
