Aims: The hemodynamic study of a coronary stenosis of intermediate severity, by testing fraction flow reserve (FFR) is essential in terms of major cardiovascular events in the short and long term. Currently not published in this context the intracoronary application of levosimendan. Objectives: To determine the hemodynamic effects of intracoronary administration of levosimendan, a vasodilator in the FFR test, compared with intracoronary adenosine. Material and methods: Were evaluated by FFR, 48 intermediate lesions in major epicardial coronary arteries. Results: Of the 48 lesions with FFR assessed, the application of adenosine versus intracoronary levosimendan, the percentage of coronary stenosis was 55.83 (± 11.64), intracoronary adenosine FFR 0.8633 (± 0.1130) and 0.8652 FFR intracoronary levosimendan (± 0.1090) correlation coefficient of 0.9859 and 0.9720 quadratic correlation. Demonstrating that induction of vasodilatation is similar, including revascularization positive cases compared FFR < 0.80. Conclusions: Intracoronary levosimendan in the FFR test showed similarity in the assessment of intermediate coronary stenosis compared with intracoronary adenosine. Levosimendan is an excellent alternative in the induction of coronary hyperemia decisions to regulate physiological revascularization with assistance.
