RESUMO

INTRODUCTION AND OBJECTIVES: The optimum treatment for patients with ST-segment elevation acute myocardial infraction (AMI) is primary percutaneous coronary intervention (PCI), provided that the door-to-balloon time is less than 90 min. The aims of this study were to determine actual treatment times in our patients, to investigate the effect of different factors in reducing those times, and to evaluate the impact of any delay on prognosis. METHODS: The study involved patients who underwent primary or rescue PCI at our center between January 2005 and October 2007. Treatment times, clinical and angiographic characteristics, and follow-up findings at 1 and 12 months were recorded prospectively. RESULTS: Overall, 389 PCIs were performed: 361 primary and 28 rescue interventions. The median total duration of ischemia was 235 [interquartile range, 170-335] min. The median door-to-balloon time was 79 [53-104] min. The door-to-balloon time was shorter when the ambulance service was able to notify the on-duty cardiologist, who alerted the interventional cardiology team. The difference was 30 [60-90] min (P< .01). Patients who arrived at the emergency department by their own means had the longest door-to-balloon time (100 min vs. 74 min; P< .01). A door-to-balloon time >120 min was associated with higher mortality at 30 days; multivariate analysis showed a clearly increasing trend. CONCLUSIONS: The door-to-balloon time at our center was in line with current recommendations, with the time being markedly shorter for patients for whom the ambulance service was able to give advanced warning. A shorter time was associated with a trend towards lower 30-day mortality.

RESUMO

The acute coronary syndromes (i.e., ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, and unstable angina) share a common pathophysiology: the rupture or breakdown of atheromatous plaque superimposed on intracoronary thrombosis (i.e., atherothrombosis). The aim of this review article was to summarize developments occurring during the last year in antithrombotic therapy for non-ST-segment elevation acute coronary syndromes. Four specific issues are considered: pretreatment with clopidogrel before percutaneous coronary intervention, antiplatelet resistance, indications for glycoprotein IIb/IIIa inhibitors in patients pretreated with clopidogrel, and the role of bivalirudine and fondaparinux in the treatment of these patients.

RESUMO

Introducción y objetivos. El mejor tratamiento para el IAM con elevación del ST es la ICPP siempre que el tiempo puerta-balón sea < 90 min. Presentamos nuestros tiempos reales y valoramos la influencia de determinados factores en su reducción, y la evolución en relación con el tiempo de demora. Métodos. Hemos recogido de manera prospectiva los tiempos, los datos clínicos y angiográficos y el seguimiento a 1 y 12 meses de los pacientes a los que se realizó una ICPP o de rescate en nuestro centro de enero de 2005 a octubre de 2007. Resultados. Se realizaron 389 angioplastias, 361 primarias y 28 de rescate. La mediana del tiempo de isquemia fue 235 [percentiles 25-75, 170-335] min. La mediana del TPG fue 79 [53-104] min. El TPG fue menor cuando el servicio de transporte urgente avisó al cardiólogo de guardia, quien puso en marcha la alerta de hemodinámica, con una diferencia de 30 [90-60] min (p < 0,01). Los pacientes que llegaron a la urgencia por sus propios medios presentaron el mayor tiempo puerta-guía (100 frente a 74 min; p < 0,01). El tiempo puerta-guía > 120 min se asoció a mayor mortalidad a 30 días y a una clara tendencia a aumentarla en el análisis multivariable. Conclusiones. El tiempo puerta-guía en nuestro medio se ajusta a las recomendaciones vigentes, con una clara reducción cuando el servicio de transporte urgente avisa con antelación. Su reducción se relaciona con una tendencia a una menor mortalidad a 30 días (AU)

RESUMO

Los síndromes coronarios agudos (infarto agudo de miocardio [IAM] con elevación del segmento ST, IAM sin elevación del ST y angina inestable) comparten una fisiopatología común: la rotura o erosión de una placa de ateroma con trombosis intracoronaria superpuesta (aterotrombosis). El objetivo de esta revisión es analizar los avances que se han producido durante el año previo en la terapia antitrombótica de los síndromes coronarios agudos sin elevación del ST (SCASEST) en 4 aspectos concretos: el pretratamiento con clopidogrel antes de la intervención coronaria percutánea, la resistencia a los antiplaquetarios, la indicación de los inhibidores de la glucoproteían IIb/IIIa en los pacientes pretratados con clopidogrel y el papel de la bivalirudina y del fondaparinux en el tratamiento de estos pacientes (AU)

RESUMO

El tratamiento hormonal sustitutivo es una de las cuestiones más difíciles a las que se enfrentan las mujeres y sus médicos. Los estudios epidemiológicos demuestran de manera consistente que las mujeres que toman tratamiento hormonal sustitutivo tienen un riesgo de padecer enfermedad coronaria sustancialmente inferior. Los datos observacionales se sustentan en hallazgos que demuestran que el tratamiento hormonal sustitutivo mejora varios factores de riesgo coronario, en especial los cambios en el perfil lipídico. Sin embargo, no se ha demostrado de forma absoluta que las hormonas ayuden a la prevención de la enfermedad cardiovascular. En mujeres sin enfermedad coronaria, el beneficio del tratamiento hormonal sustitutivo no está claro. Lo que sí han demostrado estudios clínicos recientes es que no se debe recomendar este tratamiento a mujeres con enfermedad coronaria establecida con el objetivo de obtener un beneficio cardiovascular (AU)
