CADAVID, Leonardo  and  GARCIA, Christian E. Myocardial SPECT results and cardiovascular events in two nuclear medicine departments in Bogota from 2011 to 2012. Rev. Colomb. Cardiol. [online]. 2014, vol.21, n.2, pp.86-94. ISSN 0120-5633.

Objective: This 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 methods: 183 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. Results: 14 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%). Conclusions: A 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.
