Abstract Antiphospholipid syndrome (APS) is an acquired autoimmune condition characterized by thrombotic events, pregnancy morbidity, and laboratory evidence of antiphospholipid antibodies (aPL). Management of these patients includes the prevention of a first thrombotic episode in at-risk patients (primary prevention) and preventing recurrent thrombotic complications in patients with a history of thrombosis (secondary prevention). Assessment of thrombotic risk in these patients, balanced against estimated bleeding risks associated with antithrombotic therapy could assist clinicians in determining whether antithrombotic therapy is warranted. Thrombotic risk can be assessed by evaluating a patient’s aPL profile and additional thrombotic risk factors. Although antithrombotic options for secondary prevention of venous thromboembolism (VTE) have been evaluated in clinical trials, studies in primary prevention of asymptomatic aPL-positive patients are needed. Primary prevention with aspirin may be considered in asymptomatic patients who have a high-risk aPL profile, particularly if additional risk factors are present. Secondary prevention with long-term anticoagulation is recommended based on estimated risks of VTE recurrence, although routine evaluation of thrombotic risk can assist in determining whether ongoing anticoagulation is warranted. Studies that stratify thrombotic risk in aPL-positive patients, and patients with APS evaluating antithrombotic and non-antithrombotic therapies will be useful in optimizing the management of these patients.

Antiphospholipid syndrome (APS), defined as combination of venous and/or arterial thrombosis as well as obstetric complications with antiphospholipid antibodies presence in blood, is an example of acquired thrombophilia. The thrombotic episodes in the APS course are highly recurrent, with an increasing incidence with years after secondary anticoagulant prophylaxis cessation. In between 2005-2011 a study was conducted in Poznań, Poland, with the aim to find a correlation between actual APS diagnostic guidelines (criteria from Sydney’2006) and the clinical feature of thrombosis in this syndrome with coexistence of inherited thrombophilia and risk factors for cardio-vascular disease included. Additionally, a selection of the highest thromboembolic risk group was made among asymptomatic patients with antiphospholipid antibodies (APA) detected to compare with APS patients. An association between a type of laboratory test confirming the longtime APA presence and thrombotic risk was analyzed as well. The follow up had lasted for meanly 47 months and included 75 patients (50 females and 25 males) at the mean age of 43, divided into three groups (25 persons each): I – with asymptomatic APA, IIA – with arterial episodes in the history and IIB – with past venous complications in the course of APS. The majority of them comprised persons with primary APS or with asymptomatic APA (aAPA) - without any other autoimmune diseases. The laboratory tests included: lupus anticoagulant (LA) according to the 3-step procedure recommended by ISTH (International Society on Thrombosis and Hemostasis), anticardiolipin (ACA) – of IgG and IgM class and anti-β2-glycoprotein I (aβ 2 GPI) – of IgG class, both with the cut-off value of 99 percentile. D-dimer and fibrinogen concentration, protein C and antithrombin activity, activated protein C resistance, free protein S concentration, factor VIII were further analyzed. Among comorbidities and risk factors for venous and arterial thrombosis, there was significantly more frequent incidence of autoimmune diseases in the asymptomatic group of people compared to patients after thromboembolic episodes. Most often the aAPA presence was confirmed in the LA tests – the majority of positive results appeared among patients with asymptomatic course and with past venous thrombosis as well and less frequently - in the group of arterial episodes in the history. Any significant differences were found in the reference to the incidence of thrombotic episodes in the retrospective assessment of symptomatic patients and prospective – in the whole investigated group, although the time of their occurrence after beginning of observation period almost doubled in people with past thromboembolic episodes, comparing to the earlier asymptomatic persons.

Background: Tetralogy of Fallot (TOF) is the most frequent form of congenital heart disease managed by EP physicians for potential ICD. However, few studies have reported long-term outcomes of TOF patients with ICD. Methods: Between 2005 and 2014, all TOF patients with ICD in 17 French centers were enrolled in a specific evaluation aiming to determine characteristics at implantation as well as outcomes (overall mortality, appropriate ICD therapies, and device-related complications). Results: Overall 78 patients (45±13 years, 64% males) were enrolled. A majority of patients were implanted in the setting of secondary prevention (73%), whereas the remaining (27%) in primary prevention. Among the latest group, known risk factors for sudden cardiac death were: severe pulmonary regurgitation (30%,) prior palliative shunt (50%), syncope with unknown origin (25%), inducible ventricular tachycardia (45%), QRS duration ≥180ms (18%), non-sustained ventricular tachycardia (25%), and documented sustained supra ventricular tachycardia (45%).Overall, patients implanted in the setting of primary prevention presented with a mean of 3.1±1.4 risk factors. After a mean follow-up of 4.9±3.8 years, 35 patients (45%) experienced at least one appropriate therapy (25% in the primary prevention group compared to 53% in the secondary prevention group), giving annual-incidences of 6.9% (95%CI 0.14-13.7) and 21.3% (12.4-30.3) respectively (P=0,01). The mean time between ICD implantation and the first appropriate therapy was 2.2±3.2 years, without significant differences between primary and secondary prevention. Overall, ≥one ICD-related complication occurred in 30 patients (38%), including inappropriate shock (n=9), major pocket hematoma (n=1), lead dysfunction (n=12), infection (n=4), shoulder algodystrophia (n=2), device failure or dislodgement needing reintervention (n=2). Eventually, four patients were transplanted (5%), and six patients (8%) died during the course of follow-up. Conclusions: Considering relatively long-term follow-up, patients with TOF and ICDs experience high rates of appropriate ICD therapies, in both primary and secondary prevention. Major ICD-related complications remain, however, high.

Introduction: Hypertrophic cardiomyopathy (HCM) is a leading cause of sudden cardiac death (SCD) in young adults. Implantable cardioverter defibrillators (ICD) effectively terminate ventricular tachycardia (VT) and fibrillation (VF) that cause SCD, but the reported prevalence of and patient characteristics leading to appropriate ICD therapy in HCM have been variable. Hypothesis: We hypothesized that some risk factors may be more prevalent than others in patients with HCM who receive appropriate ICD therapy and that the overall incidence of appropriate therapy may be lower than that reported previously. Methods: We retrospectively studied all patients with HCM who were treated with ICDs at our referral center from 2000-2013 to determine the rates of appropriate and inappropriate ICD therapies. Results: Of 1136 patients with HCM, we identified 135 who underwent ICD implantation (125 for primary and 10 for secondary prevention), aged 18-81 years (mean 48±17) at the time of implantation. The mean follow-up time was 5.2±4.5 years. Appropriate ICD intervention occurred in 20 of 135 patients (2.8%/year) by providing a shock or antitachycardia pacing in response to VT or VF. The annual rate of appropriate ICD therapy was 2.4%/year for primary and 7.2%/year for secondary prevention devices. Commonly used risk factors were equally prevalent among patients who received appropriate therapy and those who did not; furthermore, the likelihood of receiving appropriate therapy in the presence of each risk factor was similar (Figure). Inappropriate ICD therapy occurred in 27 patients (3.8%/year). Conclusions: ICDs provide clear benefit to patients who experience life-threatening arrhythmias, particularly those being treated for secondary prevention. However, the appropriate therapy rate for primary prevention was lower than previously reported, and no single risk factor appeared to have stronger association with appropriate ICD therapy than others.

Increased Risk

Antithrombotic therapy consisting of antiplatelet agents and/or anticoagulants is an important way to avoid atherothrombotic complications, especially in secondary prevention. Primary prevention by antithrombotic measures usually refers to the prevention of stroke in patients with atrial fibrillation and an increased risk for stroke or peripheral thromboembolic events by the use of anticoagulants. In certain situations a combination of anticoagulants and antiplatelet agents is mandatory. This chapter provides the pathophysiological background of coagulation and thrombosis, reports on the epidemiology of antithrombotic treatment, and describes the efficacy and safety of preventive antithrombotic measures in different cardiovascular indications. A short paragraph summarizes the current discussion of skipping aspirin in order to reduce the rate and severity of bleeding events.

Background and Objectives: Cardiovascular disease (CVD) prevention guidelines define targets for lifestyle and risk factors for patients at high risk of developing CVD. We assessed the control of these factors, as well as CVD risk perception in patients enrolled into the primary care arm of the European Action on Secondary and Primary Prevention by Intervention to Reduce Events (EUROASPIRE V) survey in Lithuania. Materials and Methods: Data were collected as the part of the EUROASPIRE V survey, a multicenter, prospective, cross-sectional observational study. Adults without a documented CVD who had been prescribed antihypertensive medicines and/or lipid-lowering medicines and/or treatment for diabetes (diet and/oral antidiabetic medicines and/or insulin) were eligible for the survey. Data were collected through the review of medical records, patients’ interview, physical examination and laboratory tests. Results: A total of 201 patients were enrolled. Very few patients reached targets for low-density lipoprotein cholesterol (LDL-C) (4.5%), waist circumference (17.4%) and body mass index (15.4%). Only 31% of very high CVD risk patients and 52% of high-risk patients used statins. Blood pressure target was achieved by 115 (57.2%) patients. Only 21.7% of patients at very high actual CVD risk and 27% patients at high risk correctly estimated their risk. Of patients at moderate actual CVD risk, 37.5% patients accurately self-assessed the risk. About 60%–80% of patients reported efforts to reduce the intake of sugar, salt or alcohol; more than 70% of patients were current nonsmokers. Only a third of patients reported weight reduction efforts (33.3%) or regular physical activity (27.4%). Conclusions: The control of cardiovascular risk factors in a selected group of primary prevention patients was unsatisfactory, especially in terms of LDL-C level and body weight parameters. Many patients did not accurately perceive their own risk of developing CVD.

Domain I

Antiphospholipid syndrome (APS) is diagnosed in the presence of vascular thrombosis or pregnancy morbidity occurring in patients with circulating antiphospholipid antibodies (lupus anticoagulant [LA] and/or IgG/IgM anticardiolipin [aCL] and/or IgG/IgM anti-β2glycoprotein I [aβ2GPI] antibodies). Each test may identify different autoantibodies; a single test makes the diagnosis possible when positive on two or more occasions at least 12 weeks apart. However, single test positivity may be unrelated to pathogenic antibodies, which are now considered to be a subclass of aβ2GPI antibodies directed against the domain I of this protein. Conversely, all three positive tests identify a single class of aβ2GPI antibodies, thus identifying high-risk patients with APS.

Abstract Sickle cell disease (SCD) patients are at a four- to 100-fold increased risk for thrombosis compared with the general population, although the mechanisms and risk factors are not clear. We investigated the incidence and predictors for thrombosis in a retrospective, longitudinal cohort of 1193 pediatric and adult SCD patients treated at our institution between January 2008 and December 2017. SCD diagnosis and thrombotic complications were identified using International Classification of Diseases coding and verified through medical chart review. Clinical and laboratory data were extracted from the medical records. With a median follow-up of 6.4 years, 208 (17.4%) SCD patients experienced 352 thrombotic events (64 strokes, 288 venous thromboembolisms [VTE]). Risk factors for stroke included older age and HbSS/Sβ0-genotype and a lower hemoglobin (Hb) F% in the subset of HbSS/Sβ0-genotype patients (P < .05). VTE risk was independently associated with lower estimated glomerular filtration rate, hydroxyurea (HU) use, HbSS/Sβ0 genotype, and higher white blood cell (WBC) counts and Hb (P ≤ .03). Two thrombomodulin gene variants previously associated with thrombosis in the general African American population, THBD rs2567617 (minor allele frequency [MAF] 0.25; odds ratio [OR], 1.5; P = .049) and THBD rs1998081 (MAF, 0.24; OR, 1.5; P = .059), were associated with thrombosis in this cohort. In summary, thrombotic complications are common, and several traditional and SCD-specific risk factors are associated with thrombotic risk. Future studies integrating clinical, laboratory, and genetic risk factors may improve our understanding of thrombosis and guide intervention practices in SCD.
