Analizar los factores asociados al rechazo de ofertas de donantes card\u00edacos dirigidas a la Cl\u00ednica Guayaquil y compararlos con datos nacionales del Instituto Nacional de Donaci\u00f3n y Trasplante de \u00d3rganos, Tejidos y C\u00e9lulas, para identificar tendencias que influyen en la aceptaci\u00f3n de \u00f3rganos. Materiales y m\u00e9todos. Estudio observacional y retrospectivo de ofertas card\u00edacas recibidas entre septiembre de 2021 y julio de 2025. Se recopilaron variables demogr\u00e1ficas, cl\u00ednicas, antropom\u00e9tricas y log\u00edsticas de la base institucional y del Sistema Inform\u00e1tico Nacional de Donaci\u00f3n y Trasplante (SINIDOT). Las causas de rechazo se clasificaron en ocho categor\u00edas. Se aplicaron an\u00e1lisis univariados y multivariados para identificar asociaciones. Resultados. Se recibieron 196 ofertas; el 75% fueron rechazadas. Los donantes aceptados fueron m\u00e1s j\u00f3venes, mayoritariamente masculinos y con mayor masa card\u00edaca predicha (PHM, por sus siglas en ingl\u00e9s, Predicted Heart Mass). El traumatismo craneoencef\u00e1lico fue la principal causa de muerte (49.5%). Las razones m\u00e1s frecuentes de rechazo fueron \u00abdonante de riesgo no est\u00e1ndar\u00bb (39,5%), problemas log\u00edsticos (30,6%) e incompatibilidad sangu\u00ednea (15,6%). En el an\u00e1lisis multivariado, la edad avanzada y la procedencia fuera de Guayaquil se asociaron con un mayor rechazo; el sexo masculino y un PHM elevado, con un menor rechazo. Los problemas log\u00edsticos aumentaron del 0% en 2021 a m\u00e1s del 40% en 2024\u20132025, principalmente por falta de transporte a\u00e9reo. Conclusiones. La alta tasa de rechazo refleja una subutilizaci\u00f3n de \u00f3rganos potencialmente viables. Optimizar la log\u00edstica de transporte y ampliar criterios de aceptaci\u00f3n podr\u00eda aumentar la utilizaci\u00f3n de \u00f3rganos, reducir la mortalidad en la lista de espera y mejorar la eficiencia de los programas de trasplante card\u00edaco a nivel nacional.<\/jats:p>","DOI":"10.47487\/apcyccv.v6i4.530","type":"journal-article","created":{"date-parts":[[2025,12,19]],"date-time":"2025-12-19T05:00:25Z","timestamp":1766120425000},"page":"197-206","source":"Crossref","is-referenced-by-count":0,"title":["Brecha entre disponibilidad y utilizaci\u00f3n de donantes card\u00edacos: an\u00e1lisis de factores determinantes en Ecuador","Gap between availability and utilization of cardiac donors: analysis of determining factors in Ecuador"],"prefix":"10.47487","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-6691-5020","authenticated-orcid":false,"given":"Guillermo","family":"Sol\u00f3rzano Su\u00e1rez","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4354-3139","authenticated-orcid":false,"given":"Paola","family":"Morej\u00f3n Barrag\u00e1n","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8405-5882","authenticated-orcid":false,"given":"Jos\u00e9 Miguel","family":"J\u00e1uregui Sol\u00f3rzano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5861-0237","authenticated-orcid":false,"given":"M\u00f3nica","family":"Gilbert Or\u00fas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"26947","published-online":{"date-parts":[[2025,12,18]]},"container-title":["Archivos Peruanos de Cardiolog\u00eda y Cirug\u00eda Cardiovascular"],"original-title":[],"link":[{"URL":"https:\/\/apcyccv.org.pe\/index.php\/apccc\/article\/download\/530\/713","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/apcyccv.org.pe\/index.php\/apccc\/article\/download\/530\/709","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,31]],"date-time":"2025-12-31T05:00:23Z","timestamp":1767157223000},"score":1,"resource":{"primary":{"URL":"https:\/\/apcyccv.org.pe\/index.php\/apccc\/article\/view\/530"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,12,18]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2025,12,29]]}},"URL":"https:\/\/doi.org\/10.47487\/apcyccv.v6i4.530","relation":{},"ISSN":["2708-7212"],"issn-type":[{"type":"electronic","value":"2708-7212"}],"subject":[],"published":{"date-parts":[[2025,12,18]]}}}
