The difference between men and women is clear even just by looking at an electrocardiogram: females present higher resting heart rate, a shorter QRS complex length and greater corrected QT interval. The development of these differences from pubertal age onward suggests that sexual hormones play a key role, although their effect is far from being completely understood. Different incidences between sexes have been reported for many arrhythmias, both ventricular and supraventricular, and also for sudden cardiac death...

OBJECTIVES: Anomalous aortic origin of a coronary artery is uncommon but potentially clinically significant. Manifestations vary from asymptomatic patients to those who present with angina pectoris, myocardial infarction, heart failure, syncope, arrhythmias, and sudden death. We describe our experience with surgical reimplantation and results at midterm follow-up. METHODS: Between February 2003 and July 2016, a total of 13 patients with anomalous origin of the right coronary artery (RCA) from the left sinus underwent surgical reimplantation...

REVIEW
Antonio B Fernandez, Paul D Thompson
Exercise events and sport participation have increased over recent decades. The average age of sports participants has also increased with a potential parallel increase in the number of exercise participants with both occult and diagnosed cardiovascular disease (CVD). Habitual physical activity and exercise training reduce atherosclerotic CVD (ASCVD) risk in a curvilinear fashion by affecting multiple ASCVD risk factors. Nonetheless, exercise also increases the risk of sudden cardiac death in both young and adult individuals with occult CVD making it important to balance the risks and benefits of exercise and exercise training in these individuals...

There is irrefutable evidence that regular participation in physical activity has substantial health benefits, and as such participation in mass community-based sports events should be supported. However, with the promotion of physical activity comes the potential risk of medical complications during an acute exercise session, with this risk varying according to the risk factor profile of an individual and the nature of the event. The demographics of marathon race entrants changed over the past two to three decades, and currently about 50% of runners are older than 40 yr...

Anomalous aortic origin of coronary arteries is rare. We report 3 cases of surgical treatment for anomalous aortic origin of coronary arteries. Case 1 was a 38-year-old man who was saved by the use of an automated external defibrillator from cardiopulmonary arrest while exercising. The coronary angiogram showed the right coronary artery arising from the left coronary sinus of Valsalva and being located between the aorta and the pulmonary trunk. He underwent coronary artery bypass grafting (CABG) using the right internal thoracic artery with ligation of proximal part of right coronary artery to prevent sudden death...

Aims To perform a systematic literature review and meta-analysis of clinical risk factors for sudden cardiac death (SCD) in childhood hypertrophic cardiomyopathy. Methods Medline and PubMed databases were searched for original articles published in English from 1963 through to December 2015 that included patients under 18 years of age with a primary or secondary end-point of either SCD or SCD-equivalent events (aborted cardiac arrest or appropriate implantable cardioverter-defibrillator discharge) or cardiovascular death (CVD)...

Autonomic dysfunction may account for sudden unexpected death in patients with epilepsy (PWE). On the other hand, low cardiovascular fitness, which may affect autonomic function, is a risk factor for sudden death and all-cause mortality in the general population. Little is known about autonomic variables and cardiovascular response to exercise in PWE. We submitted thirty consecutive PWE with no known cardiovascular diseases to maximal treadmill test, comparing them with matched controls. All individuals were submitted to clinical assessment, 12-lead electrocardiogram (ECG) and echocardiogram to exclude cardiovascular disease...

Renin-angiotensin-aldosterone system (RAAS) inhibition with angiotensin II receptor blockers or angiotensin-converting enzyme inhibitors is beneficial in patients with acquired left ventricular dysfunction. Adult patients with tetralogy of Fallot (TOF) with right ventricular (RV) dysfunction are at high risk for heart failure, arrhythmias, and sudden cardiac death. However, the efficacy of RAAS inhibition has not been established in these patients. METHODS: The REDEFINE is an investigator-initiated, multicenter, prospective, randomized, double-blind, placebo-controlled trial to study the effects of the angiotensin II receptor blocker losartan (target dosage of 150 mg once daily) in adult patients with TOF...

CONTEXT: Sudden cardiac death (SCD) in a young athlete is a tragic event and is the leading medical cause of death in this population. The precise incidence of SCD in young athletes has been subject of debate, with studies reporting drastically different rates (1:917,000 athlete-years (AYs) to 1:3000 AYs) depending on the methodological design of the investigation or the targeted population. EVIDENCE ACQUISITION: A literature search was performed in PubMed using the terms: incidence, sudden cardiac death, sudden death, sudden cardiac arrest, etiology, pathology, registry, athlete, young, children, and adolescents...

BACKGROUND: The features of the hypertrophic cardiomyopathy (HCM) ECG make it a challenge for subcutaneous implantable cardioverter-defibrillator (S-ICD) screening. We aimed to investigate the causes of screening failure at rest and on exercise to inform optimal S-ICD ECG vector development. METHODS AND RESULTS: One hundred and thirty-one HCM patients (age, 50±16 years; 92 males and 39 females) with ≥1 HCM risk factor for sudden death underwent S-ICD ECG screening at rest and on exercise...

Postmortem lesions and cause of death were evaluated retrospectively for 963 horses examined as part of the Ontario Racing Commission Death Registry over a 13-y period. The Death Registry was established in 2003 to identify factors leading to death or euthanasia of racehorses in this Canadian province. Postmortem examination was carried out on 56% of horses reported to the Death Registry and included Standardbred, Thoroughbred, and American Quarter Horses. Musculoskeletal injury was the most common reason for death associated with racing or training among all racehorses and involved 68% of horses...

The fluctuating course of tidal volume (VT), breathing frequency (DF) and minute ventilation (VE) during the cardio-pulmonary exercise test using a ramp incremental protocol occurs not only in patients, but relatively frequently also in healthy individuals. It can account for a number of irregularities in the course of the curves VO2, VCO2 and in particular of those of ventilatory equivalents for O2 and CO2 (EQO2, EQCO2) as well as curves of partial pressure of end-tidal oxygen and partial pressure of end-tidal carbon dioxide (PETO2, PETCO2), which are also used, inter alia, to establish ventilatory thresholds...

Understanding the functional limitation in hypertrophic cardiomyopathy, the most common inherited heart disease, is challenging. Beside the occurrence of disease-related complications, several factors are potential determinants of exercise limitation, including left ventricular hypertrophy, myocardial fiber disarray, left ventricular outflow tract obstruction, microvascular ischemia, and interstitial fibrosis. Furthermore, drugs commonly used in the daily management of these patients may interfere with exercise capacity, especially those with a negative chronotropic effect...

With increased interest in fitness and health care, jogging has become more popular as an exercise to promote health. However, sudden cardiac death during sports or exercise has also been reported. Some apparently healthy elderly individuals take up sports for both recreation and health improvement based only on completion of a questionnaire, without undergoing medical evaluation. We report the case of a 66-year-old Japanese man who suddenly died of acute ischemic heart disease during first-time jogging. He collapsed an hour after starting...

BACKGROUND: Jervell and Lange-Nielsen syndrome (Online Mendelian Inheritance in Man 220400) is a rare autosomal recessive cardioauditory ion channel disorder that affects 1/200,000 to 1/1,000,000 children. It is characterized by congenital profound bilateral sensorineural hearing loss, a long QT interval, ventricular tachyarrhythmias, and episodes of torsade de pointes on an electrocardiogram. Cardiac symptoms arise mostly in early childhood and consist of syncopal episodes during periods of stress, exercise, or fright and are associated with a high risk of sudden cardiac death...

BACKGROUND: In Switzerland, ECG screening was first recommended for national squad athletes in 1998. Since 2001 it has become mandatory in selected high-risk professional sports. Its impact on the rates of sports-related sudden cardiac death (SCD) is unknown. OBJECTIVE: We aimed to study the incidence, causes and time trends of sports-related SCD in comparison to SCD unrelated to exercise in Switzerland. METHODS: We reviewed all forensic reports of SCDs of the German-speaking region of Switzerland in the age group of 10 to 39 years, occurring between 1999 and 2010...

INTRODUCTION: Risk stratification of asymptomatic patients with a Brugada type 1 ECG pattern remains an unresolved clinical conundrum. In contrast to provocative pharmacological testing in Brugada syndrome, there is limited data on the role of exercise stress testing as a risk stratification modality. The objective of this study was to evaluate the utility of exercise testing in asymptomatic patients with type 1 Brugada pattern to prognosticate major arrhythmic events (MAE) during follow-up...
