ABSTRACT

Fundamento. Se describe la utilización de antagonistas de la glucoproteína IIb/IIIa (AGIIb/IIIa) en una serie de casos, recogidos a partir de los pacientes con síndrome coronario agudo ingresados en la UCI de un hospital sin disponibilidad de cateterismo cardíaco, entre febrero de 1999 y diciembre de 2000.Método. Estudio descriptivo y retrospectivo sobre pacientes con síndrome coronario agudo tratados con AGIIb/IIIa. Se valoró la evolución inicial, a los 6 meses y los efectos secundarios.Resultados. Se estudió a 22 pacientes (20 varones) entre febrero de 1999 y diciembre de 2000. Once pacientes recibieron abciximab (cinco antes del cateterismo cardíaco por síndrome coronario agudo de alto riesgo y seis por isquemia refractaria) y 11 enfermos tirofibán (por isquemia refractaria). Inicialmente, 12 (70,6 por ciento) de los 17 pacientes con ángor refractario quedaron asintomáticos. Se realizó cateterismo cardíaco en otro hospital en todos los pacientes menos uno. En 18 enfermos se instauró tratamiento invasivo percutáneo, 2 pacientes requirieron cirugía cardíaca, un enfermo no presentó lesiones coronarias significativas y en otro enfermo éstas no fueron susceptibles de revascularización. A los 6 meses, 18 pacientes (81,8 por ciento) permanecían asintomáticos aunque cuatro (18,2 por ciento) habían precisado nueva revascularización percutánea. En ningún caso se constató muerte por cualquier causa o infarto de miocardio de nueva aparición.Respecto a efectos secundarios, un enfermo presentó hemorragia gastrointestinal y en otro paciente se evidenció trombocitopenia grave.Conclusión. Los AGIIb/IIIa son una opción terapéutica en los pacientes ingresados por angina inestable refractaria en hospitales sin disponibilidad de cateterismo cardíaco, ya que pueden estabilizar inicialmente el síndrome coronario agudo; no obstante, son fármacos que no están exentos de importantes efectos secundarios (AU)

ABSTRACT

INTRODUCTION: In the elderly with acute myocardial infarction the risks and benefits of thrombolytic therapy are not well defined due mainly to the lack of randomized trials. In the present study we examined the clinical profile of the aged treated with thrombolytic agents and the effects of that therapy on 28 day and 1 year mortality. PATIENTS AND METHODS: We studied 733 patients aged > 75 years (mean: 79.9) admitted to the Coronary Care Unit (CCU) of 24 Spanish hospitals with a confirmed diagnosis of Q-Wave myocardial infarction (MI). On admission, 293 patients were treated with thrombolytics and 440 patients received standard therapy. The difference between the two groups in the clinical profile of MI, treatments administered in CCU, evolutive course and 28 day and 1 year mortality were assessed. RESULTS: The independent predictors related to the use of thrombolytic therapy were age (OR: 0.93; 95% CI: 0.89-0.97), history of arterial hypertension (OR: 0.85; 95% CI: 0.71-1.01), delay time to admission (OR: 0.998; 95% CI: 0.997-0.999), anterior location of infarct (OR: 1.21; 95% CI: 1.01-1.24) and Killip Class III-IV (OR: 0.79; 95% CI: 0.64-0.97). During the evolution thrombolysis therapy was associated with lower rates of Killip III-IV (p < 0.00001), complete AV block (p = 0.037), intraventricular conduction defects (p = 0.046) and a higher incidence of stroke (p < 0.01). The 28-day mortality was also significantly lower in the group receiving thrombolytics (27 vs 31. 3%; p = 0.035). However, this difference disappeared when the analysis was adjusted with other variables such as age, administration of aspirin and Killip Class III-IV (OR: 1.29; 95% IC: 0.87-1.92). CONCLUSIONS: The results of this trial suggest that in the elderly with acute myocardial infarction thrombolysis is associated with a less complicated evolutive course and a lower 28-day mortality. However, these findings could be mediated by other covariables such as age, more frequent use of aspirin and a higher number of patients with Killip Class III-IV excluded from the thrombolytic therapy.
