RESUMEN
Fundamento y

objetivo:

El objetivo de este estudio fue diseñado para investigar si dosis altas de atorvastatina antes de la intervención coronaria percutánea (PCI) pueden reducir la inflamación, la activación plaquetaria y episodios cardíacos adversos mayores (MACE) en pacientes con angina estable que se someten a terapia con estatinas a largo plazo.

Métodos:

En total, 215 pacientes con angina estable crónica fueron asignados aleatoriamente a un tratamiento previo con 80mg de atorvastatina (12h antes de la PCI, n=106) o con 20mg de atorvastatina (12h antes de la PCI, n=109). Todos los pacientes fueron sometidos a PCI. Los niveles séricos de interleucina-6, proteína C reactiva de alta sensibilidad y factor de necrosis tumoral alfa, GMP-140 y P-selectina se midieron 24h antes y después de la PCI. Se determinó la incidencia a 30 días de MACE.

Resultados:

No se observaron diferencias en las características basales entre los grupos. Los niveles de inflamación y activación de las plaquetas fueron significativamente menores a las 24h en el grupo que recibió terapia intensiva con estatinas (p<0,05). Los niveles de inflamación y activación de las plaquetas aumentaron considerablemente 24h después de la PCI en el grupo que recibió la dosis más baja de atorvastatina (p>0,05). En otras palabras, el tratamiento previo con una dosis alta de atorvastatina disminuyó notablemente la incidencia de MACE durante 30 días (p<0,05).

Conclusiones:

El tratamiento previo con una dosis alta de atorvastatina redujo significativamente la inflamación, la activación de las plaquetas y la incidencia de ECV en pacientes con angina estable (AU)
ABSTRACT
Background and

objective:

This study was designed to investigate whether high-dose atorvastatin before percutaneous coronary intervention (PCI) can reduce inflammation, platelet activation, and major adverse cardiac events (MACE) in patients with stable angina who are undergoing long-term statin therapy.

Methods:

In total, 215 patients with chronic stable angina were randomized to pretreatment with 80mg of atorvastatin (12h before PCI; n=106) or with 20mg of atorvastatin (12h before PCI; n=109). All patients underwent PCI. Serum levels of interleukin-6, high-sensitivity C-reactive protein, tumor necrosis factor-Alpha, GMP-140, and p-selectin were measured 24h before and after PCI. The 30-day incidence of MACE was determined.

Results:

No differences in baseline characteristics were observed between the groups. The levels of inflammation and platelet activation were significantly lower after 24h in the group that received intensive statin therapy (P<0.05). The levels of inflammation and platelet activation increased sharply 24h after PCI in the group that received the lower dose of atorvastatin (P>0.05). In other words, pretreatment with a high dose of atorvastatin decreased the incidence of MACE sharply within 30 days (P<0.05).

Conclusions:

Pretreatment with a high dose of atorvastatin significantly reduced inflammation, platelet activation, and the incidence of MACE in patients with stable angina (AU)
