The incidence of SD in young individuals in Cyprus was 2.16 cases per 100\u2009000 people annually. Out of the 74 recorded cases, cardiac causes were identified in 43.24% (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200932) of SD cases, with 28.38% (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200921) attributed to noncardiac factors.
