RESUMEN

El objetivo es describir nuestra experiencia, resultados clínicos y angiográficos inmediatos en pacientes con IAM sometidos a angioplastía coronaria transluminal percutánea de rescate (ACTPR). Material y métodos: Tipo de estudio; retrospectivo, observacional, transversal y descriptivo con seguimiento a 30 días. De enero de 2001 a julio de 2004 se realizaron 3,238 procedimientos de ACTP con aplicación de stent a pacientes con diagnóstico de cardiopatía isquémica por aterosclerosis coronaria, se seleccionó a 32 pacientes que representan el 0.98%, con edad de 47 a 79 años promedio de 63, 24 (75%) del sexo masculino, con hipertensión arterial sistémica 29 (90.6%), diabetes mellitus 18 (56.3%), hipercolesterolemia 11 (34.4%), tabaquismo 24 (75%), con antecedentes de angina inestable 9 (28.1%) y con infarto miocardio previo 2 (6.3%). La localización del IAM: anterior extenso 14 (43.8%), anteroseptal en 6 (18.8%), posteroinferior en 5 (15.6%), PI con extensión eléctrica y/o hemodinámica en VD en 4 (12.5%), lateral en 1 (3.1%). Se trombolizaron en un tiempo promedio 3.19 horas (rango 2-7) con estreptoquinasa 19 (59.4%) y con rTPA 13 (40.6%), la CPK-MB pico (U) promedio de 348 ± 240. Con Killip Kimball (KK) 1 en cinco (15.6%), II 16 (50%), III 5 (15.6%) y IV 6 (18.8%) éstos manejados con balón intraaórtico de contrapulsación. Resultados: Llevados a sala de hemodinamia en un tiempo de 6 a 24 h encontrando flujo TIMI 0 en 16 (50%), TIMI 1 en diez (31.2%), TIMI 2 en seis (18.8%), promedio de vasos enfermos de 1.9. Se implantó stent en 27 (84.3%). Éxito angiográfico post ACTP más stent TIMI 3 en 24 (75%). Complicaciones: En 9 (28.1%), en 7 (21.8%) con no reflujo y en 1 (3.1%) disección de la arteria coronaria relacionada con el IAM, 6 (18.7%) que fallecieron, en 4 (12.5%) con choque cardiogénico; 3 (9.3%) la ACTPR fue fallida. Conclusión: La ACTPR es un procedimiento de alto riesgo y pese a ello es una buena alternativa de tratamiento en pacientes con trombólisis fallida.
