With interest in evaluating the long term prognostic in patients with myocardial scintigraphy without isquemia after coronary angioplasty, we evaluated 183 patients, (201 vessels) among January to December 1993. All patients underwent myocardial perfusion image, using Sestamibi Tc-99m, medium period of 4,16 + 3,82 months after procedure. The Left Ventricle Ejection Fraction average was 76,6 + 7,9 performed by echocardiography .Of the analyzed patients, 151 didn't have isquemia in the scintigraphic data. Of these, only 9 (1,6%) needed new angioplasty, surgery or died in a medium period following 31,03 + 12,24 months. Of the 32 patients with isquemia in the scintigraphyc data, 23 (71,8%) needed new angioplasty, surgery or died in the same period of accompaniment (p <0,001). We concluded that those patients without isquemia in the scintigraphic myocardial perfusion after a medium period of four months, have an excellent long term prognostic in relation to need of new angioplasty or surgery and have low probability of cardiovascular death.
