| dc.description.abstract | [Abstract] Introduction and objectives: Severe primary graft dysfunction (PGD) is the leading cause of early mortality following heart transplant (HT). This study analyzed the temporal trends and mortality associated with severe PGD, identified risk factors, and developed a predictive model based on a contemporary cohort. Methods: A total of 2029 HT performed between 2010 and 2020 in 14 Spanish centers were retrospectively analyzed. Patients with and without severe PGD were compared. Logistic regression was used to identify predictors of severe PGD and to generate a risk score. Model performance was assessed in terms of calibration and discrimination. Results: The incidence of severe PGD was 10%, with an increase observed over the last 5 years (8% vs 11%). However, 30-day and 1-year mortality declined significantly (59.1% vs 38.8% and 69.7% vs 58.8%, respectively). Independent predictors of severe PGD included extracorporeal membrane oxygenation (OR, 2.79), pretransplant ventricular assist devices (OR, 2.11), donor-to-recipient weight ratio <0.8 (OR, 2.11), and congenital heart disease (OR, 2.11). A risk score was created, showing good calibration but limited discriminative ability. Conclusions: Despite a rising incidence of severe PGD, mortality showed a marked decrease. Predictors of severe PGD included congenital heart disease, a donor-to-recipient weight ratio <0.8, and the use of extracorporeal membrane oxygenation or pretransplant ventricular assist devices. The predictive model showed good calibration but only moderate discriminative performance. | |
| dc.description.abstract | [Resumen] Introducción y objetivos. El fracaso primario del injerto (FPI) grave es la principal causa de muerte tras el trasplante cardiaco (TxC). Este estudio analizó la evolución temporal y la mortalidad del FPI grave, identificó factores de riesgo y desarrolló un modelo predictivo en una cohorte contemporánea. Métodos. Se analizaron retrospectivamente 2.029 TxC realizados entre 2010-2020 en 14 centros españoles. Se compararon pacientes con y sin FPI grave. Se realizó un análisis de regresión logística para identificar predictores de FPI grave y generar una puntuación de riesgo. Se evaluó el comportamiento del modelo (calibración, discriminación). Resultados. La incidencia de FPI grave fue del 10%, y aumentó en los últimos 5 años (8 vs 11%). La mortalidad a 30 días y 1 año disminuyó significativamente (59,1 vs 38,8% y 69,7 vs 58,8%, respectivamente). Los predictores de FPI grave incluyeron oxigenador extracorpóreo de membrana (ECMO) (OR = 2,79), dispositivos de asistencia ventricular (DAV) pretrasplante (OR = 2,11), relación de peso donante/receptor (D/R) < 0,8 (OR = 2,11) y cardiopatía congénita (OR = 2,11). Se creó una puntuación de riesgo que mostró buena calibración pero una capacidad discriminatoria pobre. Conclusiones. Aunque la incidencia de FPI grave aumentó, la mortalidad disminuyó notablemente. Los predictores de FPI grave incluyeron cardiopatía congénita, relación de peso D/R < 0,8 y uso de ECMO o DAV pretrasplante. El modelo predictivo mostró buena calibración, pero capacidad discriminatoria moderada. | |
