Basic life support, including CPR and AED use, should be a requirement for all those involved in sports, including athletes. An emergency action plan is important in order to render advanced cardiac life support and arrange for transport to medical centres.","PeriodicalId":143273,"journal":{"name":"The ESC Textbook of Sports Cardiology","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121249316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Physical examination, ECG, and echocardiography are the primary diagnostic tools, whereas serology has a low sensitivity and is not generally recommended. Cardiac magnetic resonance should be performed in all athletes with suspected myocarditis, which typically reveals late gadolinium enhancement (LGE) with a patchy pattern. Patients without LGE and with ejection function >60% have a good prognosis. Endomyocardial biopsy should only be performed if there is severe impairment of myocardial function. A detailed clinical work-up should be performed for re-evaluation after 3 and 6 months.

Differentiating adaptive changes from pathological cardiac conditions is of great clinical importance because some cardiomyopathies are leading causes of sudden cardiac death in athletes. In addition, there is increasing evidence that excessive endurance training may induce intermittent atrial arrhythmias, which can be hard to detect by resting ECG.

Endurance exercise improves endothelium-dependent flow-mediated vasodilation and leads to increases in conduit artery lumen diameter after regular exercise, typically in the trained limb. These changes result in a reduced vascular stiffnes. On the contrary strength training (e.g. for weight-lifting) produces increased vascular stiffness and enlarged central vessels (e.g. aortic root diameters), while the diameters of peripheral vessels are unchanged. In the skeletal muscle, endurance training increases capillary density and improves oxygen exchange, thus adding further functional reserves to the aerobic exercise capacity. Aerobic exercise leads to a large increase in cardiac functional reserves, hence myocardial perfusion is increased in line with metabolic demands. In addition to improved endothelium-dependent vasodilation, coronary arterioles also exhibit an increased myogenic tone.","PeriodicalId":143273,"journal":{"name":"The ESC Textbook of Sports Cardiology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114667320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An exception is AF, with a two- to eightfold higher prevalence in athletes, probably due to exercise-induced atrial remodelling. Symptoms of SVTs include palpitations, dizziness, weakness, and rarely syncope, and may impair athletic performance. Except for AF in the presence of an accessory pathway, SVTs are rarely life-threatening. For treatment of AT, AVNRT, AVRT, and AFL catheter ablation is generally preferred over lifelong anti-arrhythmic drug (AAD) therapy because of high rates of resolution. Reduction of training volume and AAD therapy should be attempted in athletes with AF. However, catheter ablation of AF may be the first-line therapy in athletes with severe symptoms.

However, published estimates of SCD incidence vary widely, and are strongly influenced by the methodology used for case identification (numerator) and calculations of the population at risk (denominator). Studies searching only media reports or catastrophic insurance claims tend to underestimate SCD risk. Few studies with mandatory reporting of SCD are available, leaving significant knowledge gaps in our understanding of SCD in competitive athletes.
