RESUMEN

Evaluamos los resultados clínicos, angiográficos y el seguimiento en pacientes que fueron sometidos a angioplastía coronaria transluminal percutánea (ACTP) con colocación de “stents” en la enfermedad del tronco coronario izquierdo (TCI) y los comparamos con los enviados a cirugía de revascularización miocárdica (QX). Material y Métodos: De mayo de 1998 a octubre de 2003 se realizaron 3,680 procedimientos a 2,900 pacientes, se seleccionaron 30 pacientes, grupo GACTP; con colocación de stents en 17 protegidos y TCI no protegido, 13 inapropiados para cirugía por malos lechos y por rechazo del enfermo y grupo GRVM abordaje quirúrgico 30 pacientes, con promedio 3.2 puentes. Edades de 45 a 74 años (65.7 ± 11.5) para los de ACTP y para QX de 49 a 77 años (66.9 ± 7.1). Sexo masculino GACTP 25 (83%), GRVM 23 (76%), hipertensión arterial sistémica grupo 1 y 2: 10 (33%), tabaquismo grupo 1 y 2: 17 (56%), diabetes mellitus GACTP 11 (36%) GRVM tres (10%), hipercolesterolemia GACTP 19 (63%), GRVM 9 (30%), angina inestable según la Sociedad Canadiense de Cardiología (SCC) GACTP 17 (56%) GRVM 16 (53%) con enfermedad multivascular 20 (66%) ambos grupos. El porcentaje promedio de obstrucción fue de 90 ± 6.3%. La FE para el GACTP 30% a 55% 40.3 ± 8.7. GRVM 38% a 67% 48.6 ± 6.1. Resultados: El éxito inmediato para el GACTP 26 (87%) y GRVM 28 (90%). Complicaciones: GACTP 4 (13%) GRVM 20 (66%). IAM perioperatorio GACTP 2 (6%) GRVM 8 (26%). La mortalidad del GACTP cuatro (13%) y GRVM 3 (10%). El seguimiento GACTP de 19.4 meses y GRVM 20 ± 3, fue obtenido en 26 del total del grupo. Sobrevida tardía libre de eventos adversos mayores (MUERTE o IAM) GACTP 25 (83.3%), un paciente con IAM y para GRVM 20 (66.6%) un paciente falleció en el seguimiento. Conclusiones: La colocación de stents en enfermedad de TCI es un procedimiento factible como una alternativa de revascularización miocárdica, con bajo porcentaje de complicaciones, en casos con función ventricular conservada a pesar de su mayor perfil de riesgo.
