Objective. To determine the relationship between number of viable segments, subsequent therapeutic intervention and patient's outcome. To verify the prognostic of myocardial viability imaging in patients with post ischemic heart submitted to different therapeutic strategies.
Methods. From January 2006 through December 2007, 68 patients with post ischemic heart failure who underwent myocardial viability imaging were studied. Patient were divided into group with
Results. Seventeen hard events (cardiac death, non-fatal MI were registered during follow up. All deaths were form cardiac causes. Using Kaplan-Meier analysis, group with at least 8 viable segments had better survival advantage. Analysis by Cox proportional hazard model revealed three independent factors for cardiac event free survival: presence of at least 8 viable segments, preoperative LVEF and patient age.
Conclusion. Revascularization for post ischemic heart failure can be associated with good survival, which is critically dependent upon the amount of viable myocardium.
