Abstract

ResumenObjetivoEl estudio buscó determinar la relación que guardan los resultados obtenidos del SPECT miocárdico con estrés farmacológico con dipiridamol y el desarrollo de eventos cardiovasculares mayores en el seguimiento de los pacientes atendidos en dos servicios de medicina nuclear de Bogotá, Colombia.Materiales y métodosSe incluyeron 183 pacientes a quienes se les realizó SPECT miocárdico con estrés farmacológico con dipiridamol entre noviembre de 2011 y abril 2012 con un seguimiento de doce meses. Se analizó la relación entre el desarrollo de eventos cardiovasculares mayores y los resultados funcionales o de perfusión en el SPECT miocárdico.ResultadosEn 154 pacientes que completaron el seguimiento, se presentaron 14 eventos. Los pacientes con estudios anormales tuvieron mayor cantidad de eventos (13 vs. 1 p = 0,019) respecto a aquellos con estudios normales. Los resultados de perfusión anormal se relacionaron con mayor incidencia de eventos (15,19%).ConclusionesUn estudio SPECT miocárdico normal se asocia con incidencia reducida de eventos cardiovasculares mayores en el seguimiento a un año, aun en pacientes con características clínicas de alto riesgo.

ObjectiveThis study sought to determine the relationship between the results obtained from myocardial SPECT with pharmacologic stress with dipyridamole and the development of major cardiovascular events in the follow-up of patients treated at two nuclear medicine departments in Bogota, Colombia.Materials and methods183 patients undergoing myocardial SPECT with pharmacological stress with dipyridamole between November 2011 and April 2012 with a twelve month follow-up, were included. The relationship between the development of major cardiovascular events and the functional or perfusion results of the myocardial SPECT were analyzed.Results14 patients from the 154 who completed the follow-up, developed cardiovascular events. Patients with abnormal studies had higher number of events (13 vs 1. p = 0.019) compared to those with normal studies. The results of abnormal perfusion were associated with higher incidence of events (15.19%).ConclusionsA normal myocardial SPECT study is related to reduced incidence of major cardiovascular events in a one year follow-up, even in patients with high-risk clinical characteristics.
