Aims Limited data exist regarding the incidence and aetiology of life-threatening events such as major cardiac events or exertional heat stroke during long-distance races. We aimed to provide an updated incidence, etiology and prognosis of life-threatening events during long-distance races. Methods The prospective RACE PARIS registry recorded all life-threatening events/fatal events occurring during 46 marathons, half-marathons and other long-distance races in the Paris area between 2006 and 2016, comprising 1,073,722 runners. Event characteristics were determined by review of medical records and interviews with survivors. Results The incidence of life-threatening events, exertional heat stroke and major cardiac events was 3.35 per 100,000, 1.02 per 100,000 and 2.33 per 100,000, respectively, including 18 sudden cardiac arrests (1.67 per 100,000). The main aetiology of sudden cardiac arrest was myocardial ischaemia (11/18), due to acute coronary thrombosis (6/11), stable atherosclerotic coronary artery disease (2/11), coronary dissection (1/11), anomalous connection (1/11) or myocardial bridging (1/11). A third of participants with ischaemia-related major cardiac events presented with pre-race clinical symptoms. Major cardiac events were more frequent in the case of a high pollution index (6.78 per 100,000 vs. 2.07 per 100,000, odds ratio 3.27, 95% confidence interval 1.12–9.54). Case fatality was low (0.19 per 100,000). Similarly, we report in a meta-analysis of eight long-distance race registries comprising 16,223,866 runners a low incidence of long-distance race-related sudden cardiac arrest (0.82 per 100,000) and fatality (0.39 per 100,000). Death following sudden cardiac arrest was strongly associated with initial asystole or pulseless rhythm. Conclusion Long-distance race-related life-threatening events remain rare although serious events. Better information for runners on the risk of pre-race clinical symptoms, outside air pollution and temperature may reduce their incidence.

Artery Disease

Background: To disclose coronary artery disease (CAD) in the young is difficult by electrocardiogram screening for school students before their first events. Methods: By reviewing all reports submitted to the Mutual Aid System for Schools between 1989 and 2015, we listed all cases of sudden cardiac arrest which were considered to be caused by CAD. Kawasaki disease sequela was excluded. Epidemiology, type of CAD, symptom before onset, the intensity of the exercise at onset were investigated. Results: Thirty cases were enrolled and 26 resulted in sudden deaths, 4 were resuscitated without unfavorable sequelae. Cardioverter-defibrillator were implanted in 2 cases. Twenty-eight were male. One student was in 6th grader of primary, 11 in junior high, 15 cases in high, and 3 cases in nursing schools. Before onset, 12 cases were diagnosed as normal by ECG screening, 1 case for each was diagnosed as premature ventricular contraction, Wolff-Parkinson-White syndrome, and past history of atrial flutter. Diagnosis of 15 cases was unknown. Types based on hospital or post-mortem records: Left coronary artery (LCA); LCA of two cases were originated from the pulmonary artery, 4 cases from right coronary cuspid (RCC), and 1 from an unknown site. Two cases with LCA malformation without detail description, 3 with left ostium stenosis, and 1 with a myocardial bridge. Right coronary artery (RCA); RCA of a student was from left coronary cuspid (LCC), 1 from unknown site, 4 cases were diagnosed as hypoplastic RCA. Three cases complicated with atherosclerotic stenosis, 2 with hypoplastic CA, a case with single CA, and 4 with vasospastic angina.The school grader at onset: All of 4 cases with LCA from RCC, 2/3 with the LCA ostium stenosis and 3/4 with RCA hypoplasia were junior high school cases. Exercise intensity (level 1 to 5: most strenuous): At the onset, 19 cases were at level 5, 7 at level 4, 1 at level 3, 3 at an unknown level. Exercise at onset; soccer in 6 cases, basketball in 5, long distance running in 4, swimming, baseball, tennis, rugby, kendo, and on the way to school were in 2 for each. Conclusion: Anomalous ostium and origin of CA from the opposite side cusp tend to cause cardiac arrest in younger cases. CA evaluation by CT angiogram, MRI, or myocardial perfusion imaging is desirable.

IntroductionEarly recognition of individuals with increased risk of sudden cardiac arrest (SCA) remains challenging. SCA research so far has used data from cardiologist care, but missed most SCA victims, since they were only in general practitioner (GP) care prior to SCA. Studying individuals with type 2 diabetes (T2D) in GP care may help solve this problem, as they have increased risk for SCA, and rich clinical datasets, since they regularly visit their GP for check-up measurements. This information can be further enriched with extensive genetic and metabolic information.AimTo describe the study protocol of the REcognition of Sudden Cardiac arrest vUlnErability in Diabetes (RESCUED) project, which aims at identifying clinical, genetic and metabolic factors contributing to SCA risk in individuals with T2D, and to develop a prognostic model for the risk of SCA.MethodsThe RESCUED project combines data from dedicated SCA and T2D cohorts, and GP data, from the same region in the Netherlands. Clinical data, genetic data (common and rare variant analysis) and metabolic data (metabolomics) will be analysed (using classical analysis techniques and machine learning methods) and combined into a prognostic model for risk of SCA.ConclusionThe RESCUED project is designed to increase our ability at early recognition of elevated SCA risk through an innovative strategy of focusing on GP data and a multidimensional methodology including clinical, genetic and metabolic analyses.

Abstract Background Patients who suffer a sudden out-of-hospital cardiac arrest (OHCA) may be preceded by warning symptoms and healthcare system contact. Though, is currently difficult early identification of sudden cardiac arrest patients. Purpose We aimed to examine contacts with the healthcare system up to two weeks and one year before OHCA. Methods OHCA patients were identified from the Danish Cardiac Arrest Registry (2001–2014). The pattern of healthcare contacts (with either general practitioner (GP) or hospital) within the year prior to OHCA of OHCA patients was compared with that of 9 sex- and age-matched controls from the background general population. Additionally, we evaluated characteristics of OHCA patients according to the type of healthcare contact (GP/hospital/both/no-contact) and the including characteristics of contacts, within two weeks prior their OHCA event. Results Out of 28,955 OHCA patients (median age of 72 (62–81) years and with 67% male) of presumed cardiac cause, 16,735 (57.8%) contacted the healthcare system (GP and hospital) within two weeks prior to OHCA. From one year before OHCA, the weekly percentages of contacts to GP were relatively constant (26%) until within 2 weeks prior to OHCA where they markedly increased (54%). In comparison, 14% of the general population contacted the GP during the same period (Figure). The weekly percentages of contacts with hospitals gradually increased in OHCA patients from 3.5% to 6.5% within 6 months, peaking at the second week (6.8%), prior to OHCA. In comparison, only 2% of the general population had a hospital contact in that period (Figure). Within 2 weeks of OHCA, patients contacted GP mainly by telephone (71.6%). Hospital diagnoses were heterogenous, where ischemic heart disease (8%) and heart failure (4.5%) were the most frequent. Conclusions There is an increase in healthcare contacts prior to “sudden” OHCA and overall, 54% of OHCA-patients had contacted GP within 2 weeks before the event. This could have implications for developing future strategies for early identification of patients prior to their cardiac arrest. Figure 1. The weekly percentages of contacts to GP (red) and hospital (blue) within one year before OHCA comparing the OHCA cases to the age- and sex-matched control population (N cases = 28,955; N controls = 260,595).
