GUTIERREZ, Luis et al. Clinical and hemodynamic characterization of patients who underwent measurement of fractional flow reserve in Abood-Shaio Foundation between 2010-2011. First experience in Colombia. Rev. Colomb. Cardiol. [online]. 2013, vol.20, n.6, pp.355-362. ISSN 0120-5633.

Introduction and objectives: the physiological assessment of coronary lesions through measurement of fractional flow reserve is associated with functional revascularization without increasing mortality and myocardial infarction in follow-up and with reduction of angina. The first objective of the study is to characterize the first population studied by measuring the fractional flow reserve in Colombia, Fundación Abood-Shaio. Methods: In the years 2010-2011 we studied 50 patients and 60 coronary lesions measuring the fractional flow reserve. 68% of these patients were studied by angiography for acute coronary syndromes. The indication of the physiological assessment in 94% of the cases were intermediate lesions, 4% were ostial and 2% were multivessel coronary disease. Mean fractional flow reserve (FFR) was 0.87 (SD ± 0.075); from the total sample 11,6% of patients had a fractional flow reserve of less than 0.80 and underwent angioplasty of the evaluated lesion, being greater than 0.80 in 88,4% of the patients. Conclusion: the physiological assessment of coronary lesions using fractional flow reserve was less than 0.80 in 11,6% of cases, avoiding coronary angioplasty in 88.4% of the lesions evaluated.
