Thirdly, the final diagnosis was exclusively made by the physician responsible for the care process. Although, undoubtedly, this allows a more real approach to daily clinical practice. Fourthly, the analysis technique only allowed the analysis of a group of frequent genes and, therefore, not all the known genetic mutations were covered. Finally, the lack of a control group and subsequent follow-up limits the clinical application of the results.</p><p id="par0075" class="elsevierStylePara elsevierViewall">In conclusion, genetic mutations are frequent in young patients who present syncope during the practice of sports, especially in those with cardiac or unexplained aetiology. If these results are confirmed in future studies, the need for a more complex analysis and close follow-up of those young patients in whom the aetiology of syncope is clearly non-neuromediated seems evident.</p></span><span id="sec0025" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0085">Conflict of interests</span><p id="par0080" class="elsevierStylePara elsevierViewall">The authors declare no conflict of interest.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:10 [ 0 => array:3 [ "identificador" => "xres1099625" "titulo" => "Abstract" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0005" "titulo" => "Background and objectives" ] 1 => array:2 [ "identificador" => "abst0010" "titulo" => "Patients and methods" ] 2 => array:2 [ "identificador" => "abst0015" "titulo" => "Results" ] 3 => array:2 [ "identificador" => "abst0020" "titulo" => "Conclusions" ] ] ] 1 => array:2 [ "identificador" => "xpalclavsec1040814" "titulo" => "Keywords" ] 2 => array:3 [ "identificador" => "xres1099624" "titulo" => "Resumen" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0025" "titulo" => "Fundamento y objetivos" ] 1 => array:2 [ "identificador" => "abst0030" "titulo" => "Pacientes y métodos" ] 2 => array:2 [ "identificador" => "abst0035" "titulo" => "Resultados" ] 3 => array:2 [ "identificador" => "abst0040" "titulo" => "Conclusiones" ] ] ] 3 => array:2 [ "identificador" => "xpalclavsec1040815" "titulo" => "Palabras clave" ] 4 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 5 => array:2 [ "identificador" => "sec0010" "titulo" => "Patients and method" ] 6 => array:2 [ "identificador" => "sec0015" "titulo" => "Results" ] 7 => array:2 [ "identificador" => "sec0020" "titulo" => "Discussion" ] 8 => array:2 [ "identificador" => "sec0025" "titulo" => "Conflict of interests" ] 9 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2017-12-08" "fechaAceptado" => "2018-03-15" "PalabrasClave" => array:2 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec1040814" "palabras" => array:3 [ 0 => "Exertional syncope" 1 => "Sudden cardiac death" 2 => "Genetic" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec1040815" "palabras" => array:3 [ 0 => "Síncope de esfuerzo" 1 => "Muerte súbita" 2 => "Genética" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:3 [ "titulo" => "Abstract" "resumen" => "<span id="abst0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Background and objectives</span><p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">To study the frequency of genetic mutations related to genetic heart disease among young patients admitted for syncope during sport practice.</p></span> <span id="abst0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0015">Patients and methods</span><p id="spar0010" class="elsevierStyleSimplePara elsevierViewall">A case series study that included patients ≤45 years admitted for syncope during sport practice during 2010–2011.
