RESUMO

Resumen Introducción: en pacientes con cardiopatía isquémica crónica, ranolazina se ha mostrado eficaz ante casos de angina. Estudios recientes la valoran como fármaco para prevenir la fibrilación auricular poscardioversión eléctrica, posquirúrgica o posinfarto. Objetivos: valorar la presencia a largo plazo de episodios de fibrilación auricular de novo en pacientes con cardiopatía isquémica crónica y nuevo episodio de angina inestable que inician ranolazina 350 o 500 mg/12 h, en comparación con el tratamiento habitual. Métodos: estudio observacional retrospectivo que compara la incidencia de fibrilación auricular de novo en 77 pacientes consecutivos, con diagnóstico de cardiopatía isquémica no revascularizable y nuevo ingreso por síndrome coronario agudo durante el año 2013, en comparación con los que iniciaron ranolazina frente a tratamiento convencional, en los 12 meses siguientes al evento. La detección de fibrilación auricular se basó en su presencia en un primer registro electrocardiográfico. Resultados: de 77 pacientes, 38 iniciaron ranolazina, sin diferencias en cuanto a las características basales de las dos poblaciones, con similares tasas de factores de riesgo cardiovascular clásicos, datos ecocardiográficos como tamaño auricular, o tratamiento previo empleado. Se observó una tasa de fibrilación auricular de novo del 5,3% en los pacientes tratados con ranolazina, frente al 23,1% en el grupo sin ranolazina (p<0,001). Al analizar el subgrupo de pacientes que presentó fibrilación auricular en su seguimiento, únicamente es significativa la no toma de ranolazina (p<0,001). Conclusión: el uso de ranolazina en pacientes con cardiopatía isquémica crónica no revascularizable podría suponer un efecto protector para el desarrollo de fibrilación auricular durante un seguimiento de al menos doce meses.


Abstract Introduction: Ranolazine has shown to be effective in cases of angina in patients with chronic ischaemic heart disease. Recent studies have evaluated it as a drug to prevent electrical post-cardioversion, post-surgical or post-infarction atrial fibrillation. Objectives: To perform a long-term evaluation of de novo atrial fibrillation episodes in patients with chronic ischaemic heart disease and a new episode of unstable angina that are taking 350 or 500 mg/12 h of ranolazine, in comparison with usual treatment. Methods: An observational, retrospective study was performed to compare the incidence of de novo atrial fibrillation in 77 consecutive patients with a diagnosis of non-revascularisable ischaemic heart disease and a new hospital admission due to acute coronary syndrome during the year 2013. These were compared with those that started with ranolazine and those on conventional treatment in the 12 months following the event. The detection of atrial fibrillation was based on its presence in a first electrocardiographic register. Results: Of the 77 patients, 38 were started on ranolazine, with no differences as regards the baseline characteristics of the two populations. They had similar rates of classic cardiovascular risk factors, echocardiographic data, such as atrial size, or previous treatment employed. A de novo atrial fibrillation rate of 5.3% was observed in the patients treated with ranolazine, compared to 23.1% in the non-ranolazine group (P<.001). On analysing the sub-group of patients that had an atrial fibrillation in their follow-up, only not taking of ranolazine was significant (P<.001). Conclusion: The use of ranolazine in patients with non-revascularisable ischaemic heart disease could have a protective effect against the development of atrial fibrillation during a 12 months follow-up.
