Pronóstico de la enfermedad coronaria crónica mediante gated-SPECT de perfusión miocárdica

A wide range of scientific evidence supports the use of nuclear cardiology techniques in making vital therapeutic decisions, even, in certain situations, when coronary angiography findings are not available. However, not all clinicians make use of these techniques. The data provided by gated SPECT are particularly useful, especially in intermediaterisk patients, and their clinical value in therapeutic decisionmaking has been clearly demonstrated. In Spain, however, some cardiology departments still do not include gated SPECT in the routine assessment of patients with chronic coronary artery disease. This review discusses the current literature on the use of myocardial perfusion gated SPECT in determining prognosis in chronic coronary artery disease and summarizes, in tabular form, the most important objective qualitative and quantitative parameters used for classifying patients as high, intermediate or low risk.
