The beneficial effect of revascularization on jeopardized myocardium: reverse remodeling and improved long-term prognosis.

Objectives: To evaluate the impact of viability/ischemia before revascularization on improvement in systolic performance, reverse remodeling, symptoms and long-term prognosis post-revascularization.

Methods: Fifty patients underwent thallium-201 imaging before revascularization to assess stress-induced ischemia and viability ('jeopardized myocardium'). Left ventricular (LV) ejection fraction (EF), LV end-systolic volume index (LVESVI) and LV end-diastolic volume index (LVEDVI) were determined before and 3 months post-revascularization.
