Abstract BACKGROUND Left ventricular noncompaction (LVNC) is associated with an increased risk of systemic embolisms (SE). However, incidence and risk factors are not well established. PURPOSE To evaluate the rate of SE in LVNC and describe risk factors. METHODS LNVC patients were included in a multicentric registry. Those with SE were considered for the analysis. RESULTS 514 patients with LVNC from 10 Spanish centres were recruited from 2000 to 2018. During a median follow-up of 4.2 years (IQR 1.9-7.1), 23 patients (4.5%) had a SE. Patients with SE (Table 1) were older at diagnosis, with no differences in gender and had similar cardiovascular risk factors. They were more frequently under oral anticoagulation (OAC). Besides, they had a more reduced LVEF, and more dilated LV and left atrium (LA). Late gadolinium enhancement (LGE) was more frequent, altogether suggesting a more severe phenotype. Patients with SE had non-significantly higher rates of hospitalization for heart failure (33% Vs 24%, p = 0.31) and atrial fibrillation (35% Vs 19%, p = 0.10). In multivariate analysis, only LA diameter was an independent predictor of SE (OR 1.04, p = 0.04). A LA diameter > 45 mm had an independent 3 fold increased risk of SE (OR 3.04, p = 0.02) (Image 1). CONCLUSIONS LVNC carries a moderate mid-term risk of SE, which appears to be irrespective of atrial fibrillation and associated with age, LV dilatation and systolic dysfunction and mainly LA dilatation. This subgroup of patients should be considered for oral anticoagulation in primary prevention.

Left ventricular noncompaction is a primary cardiomyopathy with genetic transmission in the vast majority of autosomal dominant cases. It is characterized by the presence of excessive myocardial trabecularities that generally affect the left ventricle. In diagnosing this condition, echocardiography is the gold standard, although this method involves an increased risk of overdiagnosis and underdiagnosis. There are also uncertain cases where echocardiography is inconclusive, a multimodal approach is needed, correlating echocardiographic results with those obtained by magnetic resonance imaging. The clinical picture may range from asymptomatic patients to patients with heart failure, supraventricular or ventricular arrhythmias, thromboembolic events and even sudden cardiac death. There is no specific treatment of left ventricular noncompaction, but the treatment is aimed at preventing and treating the complications of the disease. We will present the case of a young patient with left ventricular noncompactioncardiomyopathy and highlight the essential role of transthoracic echocardiography in diagnosing this rare heart disease.

Introduction Better data regarding the incidence and risk factors for sudden cardiac death (SCD) in children with cardiomyopathy (CM) is critical in defining appropriate primary prevention strategies. Methods The National Australian Childhood Cardiomyopathy Study is a prospective cohort study, including all children in Australia with primary CM diagnosed at 0 – 10 years of age, between 1987–1997. SCD was defined as sudden and unexpected death in children who were not hospitalized and not in congestive heart failure at the time of death. Nine subjects with sudden death as presenting symptom were excluded. Indexed echocardiographic measurements at latest follow-up were compared between subjects with SCD and survivors. Results Study criteria were met by 291 children. Mean duration of follow-up was 9.2 years. The incidence of sudden death relative to each CM type, for all cases and as a proportion of deaths, is shown in the Table : Incidence of SCD by CM type. SCD incidence was significantly associated with CM type, for all cases ( p = 0.006) and when only those subjects who died were considered ( p = 0.005), with LVNC and RCM having up to 4 times the risk of other CM types. Children with familial DCM had a significantly higher rate of SCD than subjects with non-familial CM (12% vs 3%; p = 0.028), however, familial CM was not a risk factor in other CM types. DCM SCD subjects had larger LVEDd Z score than survivors (median 5.53 vs 1.16; p <0.0001) and lower FS Z score (median −9.23 vs −0.51; p = 0.0025). HCM SCD subjects had thicker LVPW dimension Z scores than survivors (median 4.63 vs 1.18; p = 0.007). Twelve subjects (2 DCM, 8 HCM and 2 LVNC) underwent ICD implantation (8/12 for primary prevention). Conclusions: This population based study defines new risk factors for sudden death in children with CM. RCM is well known to have a high incidence of SCD. In addition, children with LVNC and those with DCM who have severe dilatation, systolic dysfunction or familial DCM are at increased risk of sudden death.

Abstract Background: Ximelagatran is a novel oral direct thrombin inhibitor that is as effective as warfarin in preventing stroke and other thromboembolic complications in patients with nonvalvular atrial fibrillation (AF). Risk factors for bleeding with warfarin are known, but risk factors for bleeding with ximelagatran have not been described. Unlike warfarin, ximelagatran has a predictable anticoagulant effect, does not require anticoagulation monitoring, has a low potential for interactions with drugs, food, or alcohol, and is not affected by genetic polymorphisms. We undertook an exploratory analysis of a large patient database to identify conventional and novel risk factors for bleeding in ximelagatran-treated patients, in warfarin-treated patients, and in all patients, irrespective of treatment. Methods: We undertook a pooled analysis of the SPORTIF III and V trials trials, which included 7329 patients with nonvalvular AF who received oral ximelagatran, 36 mg twice daily, or warfarin, administered to achieve a target international normalized ratio of 2.0–3.0. Patients had nonvalvular AF and 1 or more risk factors for stroke: hypertension; age ≥75 years; previous stroke, transient ischemic attack (TIA) or systemic embolism; left ventricular dysfunction; age ≥65 years and coronary artery disease; or age ≥65 years and diabetes mellitus. Major exclusion criteria were: mitral stenosis; previous heart valve surgery; transient AF; increased risk for bleeding. Multivariate logistic regression analysis was used to identify independent risk factors for major bleeding. The hazard ratio (HR) for major bleeding, and corresponding 95% confidence interval (CI), was calculated for each variable in the regression model. Results: The Table presents risk factors in which there was a significant or a non-significant (NS) association with major bleeding in ximelagatran-treated or warfarin-treated patients, and in the combined patient population. Risk factor Ximelagatran-treated patients, HR (95% CI) Warfarin-treated patients, HR (95% CI) Combined patient population, HR (95% CI) Aspirin use 1.65 (1.07, 2.55) 2.40 (1.69, 3.42) 1.96 (1.49, 2.58) Increasing age 1.03 (1.01, 1.05) 1.06 (1.03, 1.08) 1.04 (1.03, 1.06) Prior liver disease NS 4.96 (1.57, 15.62) NS Prior stroke or TIA 1.78 (1.16, 2.73) NS NS Diabetes mellitus 1.80 (1.18, 2.75) NS 1.39 (1.05, 1.86) Asian race NS NS 1.99 (1.16, 3.42) Statin use 0.62 (0.39, 0.97) 0.61 (0.42, 0.88) 0.62 (0.39, 0.97) Conclusions: Overall, the bleeding risk was lower with ximelagatran compared with warfarin. Aspirin use and increasing age were associated with an increased risk of bleeding in both ximelagatran- and warfarin-treated patients. Statin use was associated with a decreased risk for bleeding in both groups.

Aims: Heart failure (HF) is frequently accompanied by atrial fibrillation (AF), a combination that worsens the outcomes of both diseases. Despite advances in the treatment of AF, it remains a serious and unsolved problem for clinicians and researchers. The aim of this study was to examine risk factors for incidents of paroxysmal and persistent AF in patients having heart failure with mid-range ejection fraction (HFmrEF). Methods. Overall, 71 patients with HFmrEF and non-valvular AF, including paroxysmal and persistent types, were enrolled in this study. As a control group, 42 HFmrEF patients without AF were also enrolled. All patients underwent detailed physical examination, including resting electrocardiography, echocardiography, and 24-hour ambulatory Holter monitoring. Levels of the inflammation markers high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and tumor necrosis factor α (TNF-α) and the fibrotic marker transforming growth factor-β1 (TGF-β1) were measured by ELISA and expressed as odds ratios. Results: We show that paroxysmal AF was associated with higher diastolic blood pressure, whereas both paroxysmal and persistent forms of AF were associated with more frequent occurrence of hypertensive crisis episodes and greater body mass index. Progression from paroxysmal to persistent AF was associated with significant ventricular remodeling. Persistent and paroxysmal AF were associated with higher levels of inflammatory markers when compared to HFmrEF patients having no AF. In addition, TGF-1 was significantly increased in HFmrEF patients having persistent but not paroxysmal AF. Conclusions: Occurrence of AF, first paroxysmal and then persistent, in HFmrEF patients is associated with left ventricular remodeling and the appearance of systemic inflammatory and fibrotic markers. Changes in those parameters may be indicators by which to identify patients at increased risk of atrial fibrillation. Further studies are needed to determine the prognostic validity of these markers.

Introduction Left ventricular noncompaction (LVNC) is classified as a genetic cardiomyopathy characterized by a progressive systolic dysfunction. It may occur alone or in association with congenital cardiac anomalies. The combination of left ventricular noncompaction with partial atrioventricular canal defect is rare and has not, to our knowledge, been described previously. Case presentation A 21-year-old male who traveled to our center from a neighboring country presented with signs of heart failure. Transthorarcic echocardiography showed prominent trabeculations in the left ventricle predominantly in the left ventricle involving the apical lateral and mid anterolateral segments associated with a partial atrioventricular canal defect. There was a biventricular systolic dysfunction. There was good response to medical treatment. Conclusion This case stresses the importance of maintaining a high degree of suspicion for this rare cardiomyopathy and the need to systematically look for other associated anomalies in order to institute proper short- and long-term managements.

Abstract Funding Acknowledgements Pfizer Israel Background Diabetes mellitus (DM) is associated with increased risk of embolic complications in non-valvular atrial fibrillation (NVAF). Whether the risk of stroke in AF patients remains the same among the wide spectrum of disease is yet to be determined. Aim Among individuals with AF and DM, to assess the incidence rates and risk of ischemic stroke and mortality by baseline HbA1C levels. Methods We conducted a prospective, historical cohort study using the Clalit Health Services (CHS) electronic medical records database. The study population included all CHS members ≥ 21 years old, with a first diagnosis of NVAF between January 1, 2010 to December 31, 2016 and a minimal follow-up period of 1 year. Among those patients identified as diabetics, we compared three groups of patients according to HBA1C levels at the time of AF diagnosis: &lt;7.0%, between 7-9% and ≥ 9%. Results A total of 44,451 cases were identified. The median age was 75 years (IQR 65-83) and 52.5% were women. During a mean follow up of 38 months, the incidence of stroke per 100 person-years in the three study groups was: 1.9 in patients with HBA1C &lt;7%, 2.37 in the intermediary group and 2.72 in those with HBA1C &gt;9%. In both univariate and multivariate analyses, higher levels of HBA1C were associated with an increased risk of stroke compared with a dose-dependent response when compared to individuals with HBA1C &lt;7% (Adjusted Hazard Ratio (AHR) = 1.32 {95% CI 1.12-1.55}for levels between 7-9% and AHR 1.64 {95% CI 1.28-2.09}) even after adjusting for CHA2DS2-VASC individual risk factors and use of oral anti-coagulants. The risk for overall mortality did not differ significantly between groups, with a slight elevation in the HBA1C &gt;9% group after adjusted analysis {aHR = 1.17 (1.07- 1.28)} Conclusion: In this observational cohort of patients with incident newly diagnosed nonvalvular atrial fibrillation, HBA1C levels were associated with an increased risk of stroke in a dose-dependent manner even after accounting for other recognized risk factors for stroke in this population.
