[Value of gated-SPECT in defining the post-revascularization prognosis of @entity1 with XXXX ].

@entity1 @entity296 @entity204 @entity1188
INTRODUCTION AND OBJECTIVES: Gated-SPECT simultaneously evaluates perfusion and ventricular function and could provide important prognostic information in @entity296 . Our aim was to study the value of gated-SPECT performed before revascularization in a cardioischemic population to predict the outcome of revascularization. METHODS: One hundred and ten @entity1 who had undergone percutaneous (n = 100) or surgical revascularization were included. @entity1 underwent sestamibi gated-SPECT before revascularization. After revascularization, they were followed-up for at least 12 months (mean 23.7 months, maximum 44 months). We recorded @entity204 and a combined clinical event of @entity204 , non-fatal @entity1188 , and hospital re-admission for cardiac reasons. We analyzed the prognostic value of clinical, angiographic, and gated-SPECT variables. RESULTS: During follow-up, there were 14 @entity204 (6.4%/ year) and 36 cases of combined events (16.5%/year). Multivariate analysis showed that depressed gated-SPECT ejection fraction (threshold 0.30) was the only variable independently related to @entity204 (OR = 4.8; 95%CI, 1.6-14.6) and combined event (OR = 2.5; 95%CI, 1.2-4.8). Survival analysis showed that @entity1 with ejection fraction < or = 0.30% had a significantly shorter period of time free of @entity204 (33 months [28-38] versus 42 months [40-44]; p = 0.002) and combined events (28 months [23-32] versus 36 months [33-39]; p = 0.007). CONCLUSIONS: Gated-SPECT, due to the information it provides about left ventricular function, predicts the prognosis of @entity1 after coronary revascularization.
