AbstractSince its recognition as a clinical entity in 1992, the Brugada Syndrome (BrS), a hereditary disease characterized by a typical electrocardiogram (ECG) pattern potentially predisposing to sudden cardiac death (SCD), has attracted the attention of many physicians for its circadian pattern of ventricular arrhythmias (VA), mostly occurring at rest. Exercise may potentially worsen the ECG abnormalities in BrS patients, resulting in higher peak J-point amplitudes during the vasovagal reaction of the recovery period, possibly leading to an increased risk of cardiac events. Moreover, the enhanced vagal tone in athletes could be both a BrS risk factor and an exercise effect. Therefore, the true risk of a BrS patient during exercise is still unclear. This review summarizes current knowledge, shortcomings and open questions on BrS and exercise. The paper, in particular, underlines specific considerations including BrS diagnostic criteria and differential diagnosis in athletes, the genetic basis, the autonomic imbalance during exercise practice and the recommendations for athletic participation in this patient group.

Abstract Aims The Brugada syndrome (Brs) is an inherited disorder associated with risk of ventricular fibrillation and sudden cardiac death in a structurally normal heart. The purpose of this case presentation was to spread awareness about this condition, highlight the importance of timely diagnosis and effective treatment of this channelopathy especially in asymptomatic young athletes at high risk of sudden cardiac death. Methods and results In this report, we discuss the case of a 47-year-old male. He was a tennis player who performed a visit to the sports doctor to have issued a certificate for competitive fitness. He had no familiar history of sudden death or syncope. The patient’s electrocardiogram (ECG) revealed J-point elevation and ST-segment elevation in the right precordial leads V1 and V2 positioned in the second, third, or fourth intercostal space, showing classic type II ‘saddleback’ morphology in V2 and BrS was suspected. Hence, the patient underwent Holter ECG monitoring with evidence of spontaneous type 1 Brugada pattern (‘coved’ morphology), as well as frequent ventricular ectopic beats with left branch block morphology. Indeed, a diagnosis of BrS was made. Antiarrhythmic prophylaxis therapy with hydroquinidine was initiated and the patient was suspended from competitive activity with a 3-month follow-up. Conclusions The BrS is a hereditary disease characterized by a typical ECG pattern potentially predisposing active individuals with no patent structural heart disease to ventricular arrhythmias (VA) and sudden cardiac death (SCD). Nowadays, it is difficult to discern the true burden of BrS due to the unknown real prevalence of asymptomatic patients and the dynamic variability of the ECG pattern in individuals. The purpose of this case presentation was to spread awareness about this condition, highlight the importance of timely diagnosis, and effective treatment of this channelopathy especially in asymptomatic young athletes at high risk of SCD. Indeed, exercise may potentially worsen the ECG abnormalities in BrS patients, resulting in higher peak J-point amplitudes during the vasovagal reaction of the recovery period, possibly leading to an increased risk of cardiac events. Moreover, the enhanced vagal tone in athletes could be both a BrS risk factor and an exercise effect. For this reason, athletic pre-participation screening is essential for minimizing the risk for SCD in athletes participating in either competitive or leisure sporting activities.

Interpretation of the athlete’s 12-lead electrocardiogram (ECG) should be based on specific criteria because changes that would be considered abnormal in the untrained population may develop in trained athletes as a physiological and benign consequence of the heart’s adaptation to exercise. ECG abnormalities in athletes are classified into two groups—‘common and training-related’ (Group 1) and ‘uncommon and training-unrelated’ (Group 2)—based on their prevalence, relation to exercise training, association with an increased risk of cardiovascular disease, and need for further investigations. The present chapter reviews the abnormalities that may be found in an athlete ECG and proposes criteria for interpretation of such changes as normal variants or abnormal findings that need further assessment to exclude an underlying cardiac disease.

Athlete's Heart

The electrocardiogram (ECG) of trained athletes may show changes that represent the consequence of the heart’s adaptation to physical exercise (‘athlete’s heart’) such as enlarged cardiac chamber size and increased vagal tone. Physiological ECG changes must be differentiated from the ECG abnormalities secondary to an underlying cardiovascular disease that may be responsible for sudden cardiac death during exercise. The ECG changes of athletes are classified according to their prevalence, relation to exercise training, association with an increased risk of cardiovascular disease, and the need for further investigations: common ECG changes should be considered as a benign sign of physiological adaptation to exercise and do not require additional evaluation; on the other hand, in case of uncommon and training-unrelated abnormalities, which may be associated with an underlying cardiovascular disease, further work-up should be performed. This chapter reviews the abnormalities that may be found in an athlete’s ECG and proposes criteria for interpretation of such changes as normal or abnormal findings.

Brugada syndrome (BrS) is a rare, autosomal dominant genetic disorder with mutation in the SCN5A gene. It is associated with an increased risk of arrhythmias and sudden cardiac death. BrS can be diagnosed by characteristic electrocardiogram (ECG) findings and significant events, such as syncope, palpitations, nocturnal respiratory agonia, and family history of sudden cardiac death below the age of 45 years. Special investigations, such as electrophysiology study, ajmaline provocation test, and genetic testing, play an important role in its diagnosis. This case report describes a patient who presented with chest pain and dizziness along with a positive family history of sudden cardiac deaths below the age of 45 years. He was discovered to have type 2 Brugada pattern on ECG, and by ajmaline provocation test, the type 1 pattern was unmasked, which established a definitive diagnosis of BrS. The patient was then advised for an implantable cardioverter-defibrillator. This case highlights the need for physicians to be competent in identifying patients with BrS in order to provide the necessary management and prevent fatal outcomes.

Ruminating about a prior anger provoking event is found to elevate blood pressure (BP) and delay BP recovery. Delayed BP recovery may be associated with increased risk of hypertension. Interventions that improve BP recovery may be beneficial for cardiovascular health. The purposes of this study were to evaluate the influence of rumination and anger on BP reactivity and recovery, to compare the effect of an exercise intervention or distraction intervention on BP recovery and to explore if exercise improved BP recovery by distracting participants from stressor-related rumination and anger. Healthy, normotensive participants (n = 79, mean age 22.2 ± 4.0 years) underwent an anger-recall interview stressor task, 3 min of exercise (walking), distraction (reading) or no-intervention (quiet sitting) and a 15 min recovery period. State anger reactivity was associated with Δ diastolic (D) BP reactivity and approached significance with Δ systolic (S) BP reactivity. Trait rumination was associated with greater SBP during recovery. Δ SBP recovery did not differ between the exercise, distraction and no-intervention groups. Although there were no differences in Δ DBP recovery between the exercise and no-intervention groups, distraction improved Δ DBP recovery compared to the exercise intervention but not the no-intervention. The proportion of anger-related thoughts (state rumination) in the exercise group did not differ from the distraction or no-intervention groups. However, a smaller proportion of participants in the distraction intervention reported an anger-related thought during recovery compared to the no-intervention group with 76% of their thoughts relating to the provided distraction. Overall, post-stressor exercise was not found to improve BP recovery while reading was effective at distracting individuals from angry thoughts (state rumination) but had no effect on BP compared to no-intervention.

ABSTRACT Background: The electrocardiogram (ECG) can aid in identification of chronic kidney disease (CKD) patients at high risk for cardiovascular diseases. Cohort studies describe ECG abnormalities in patients on hemodialysis (HD), but we did not find data comparing ECG abnormalities among patients with normal kidney function or peritoneal dialysis (PD) to those on hemodialysis. We hypothesized that ECG conduction abnormalities would be more common, and cardiac conduction interval times longer, among patients on hemodialysis vs. those on peritoneal dialysis and CKD 1 or 2. Methods: Retrospective review of adult inpatients’ charts, comparing those with billing codes for “Hemodialysis” vs. inpatients without those charges, and an outpatient peritoneal dialysis cohort. Patients with CKD 3 or 4 were excluded. Results: One hundred and sixty-seven charts were reviewed. ECG conduction intervals were consistently and statistically longer among hemodialysis patients (n=88) vs. peritoneal dialysis (n=22) and CKD stage 1 and 2 (n=57): PR (175±35 vs 160±44 vs 157±22 msec) (p=0.009), QRS (115±32 vs. 111±31 vs 91±18 msec) (p=0.001), QT (411±71 vs. 403±46 vs 374±55 msec) (p=0.006), QTc (487±49 vs. 464±38 vs 452±52 msec) (p=0.0001). The only significantly different conduction abnormality was prevalence of left bundle branch block: 13.6% among HD patients, 5% in PD, and 2% in CKD 1 and 2 (p=0.03). Conclusion: To our knowledge, this is the first study to report that ECG conduction intervals are significantly longer as one progresses from CKD Stage 1 and 2, to PD, to HD. These and other data support the need for future research to utilize ECG conduction times to identify dialysis patients who could potentially benefit from proactive cardiac evaluations and risk reduction.

Artery Disease

Background: Peripheral artery disease is a common manifestation of systemic atherosclerosis which strongly correlates to cardiovascular morbidity and mortality. In addition, the progression of peripheral artery disease leads to an increased risk of limb loss. In order to reduce these events, the benchmark of treatment and research over the last years has been the antiplatelet therapy which aims at inhibition of platelet aggregation. Over the last years, new studies combining antiplatelet agents in different therapeutic schemes have been proven efficacious. Unfortunately, patients remain still at high risk of CV events. Novel Oral Anticoagulants have been introduced as alternatives to warfarin, in the prevention and treatment of venous thromboembolism. The rationale of using medication which acts on platelet activation and the coagulation pathway of thrombosis has led investigators to examine the role of Noac's in preventing CV events in patients with peripheral artery disease, stable or unstable. Methods: The aim of this study is to review the current evidence with respect to recently published studies concerning the use of Novel anticoagulants in peripheral artery disease. Results: The Compass trial has shown that a combination of rivaroxaban with traditional therapy may produce promising results in reducing amputation rates, stroke, cardiac events, and mortality, however, there are still safety issues with bleeding requiring acute care. The ePAD study has provided us with insight concerning safety and efficacy after peripheral angioplasty or stenting and actually the need for further research. The Voyager Pad study, following the steps of Compass, is studying the effect and safety of the addition of rivaroxaban to traditional therapy in the highest risk population aka patients undergoing peripheral revascularization. The evidence concerning patients with concomitant atrial fibrillation appears to be insufficient, however, recent guidelines propose the use of novel oral anticoagulants. Conclusion: For the time being, novel oral anticoagulants in combination with aspirin may provide an alternative treatment in PAD, however, it is deemed necessary to identify patient subgroups who will benefit the most.

Number Of Individuals

Individuals with Down syndrome (DS) have an increased risk for epilepsy during the whole lifespan, but especially after age 40 years. The increase in the number of individuals with DS living into late middle age due to improved health care is resulting in an increase in epilepsy prevalence in this population. However, these epileptic seizures are probably underdiagnosed and inadequately treated. This late onset epilepsy is linked to the development of symptomatic Alzheimer’s disease (AD), which is the main comorbidity in adults with DS with a cumulative incidence of more than 90% of adults by the seventh decade. More than 50% of patients with DS and AD dementia will most likely develop epilepsy, which in this context has a specific clinical presentation in the form of generalized myoclonic epilepsy. This epilepsy, named late onset myoclonic epilepsy (LOMEDS) affects the quality of life, might be associated with worse cognitive and functional outcomes in patients with AD dementia and has an impact on mortality. This review aims to summarize the current knowledge about the clinical and electrophysiological characteristics, diagnosis and treatment of epileptic seizures in the DS population, with a special emphasis on LOMEDS. Raised awareness and a better understanding of epilepsy in DS from families, caregivers and clinicians could enable earlier diagnoses and better treatments for individuals with DS.
