[Prognostic value of normal myocardial perfusion scintigraphy with 201Tl in post-acute XXXX ].

@entity1 @entity6 @entity1188 @entity583 @entity204
OBJECTIVE: The purpose of this work has been to determine the prognostic value of normal thallium-201 myocardial perfusion scintigraphy (MPS) in @entity1 who had suffered @entity583 in the three months prior to the examination. MATERIAL AND METHODS: A stress test followed by (201)Tl Gated SPECT was performed. A follow-up was made of 63 @entity1 with normal perfusion scintigraphy. According to the MPS results, the @entity1 were divided into 2 groups. Group I (n=63; 57% males, age 65  12), @entity1 with normal MPS, and group II (n=60; 81% males, age 64  10), @entity1 with abnormal MPS. The appearance of a new @entity1188 or @entity204 occurring during this period (63  3 months) was analyzed. The appearance of events was related with the cardiovascular risk factors, perfusion study and ventricular function. RESULTS: Five events occurred in group I in 4 @entity1 : 3 new @entity1188 and 2 @entity204 . In group II, there were 18 events in 14 @entity1 : 8 new @entity1188 and 10 @entity204 (p<0,0001). The events were related with age, time from MPS, @entity6 , size of perfusion defect and post stress ventricular ejection fraction. Mean survival en group I was 108 months (103-112) and in group II 97 (88-107) (p=0,01). CONCLUSION: @entity1 with normal MPS had fewer major events than @entity1 with abnormal MPS. The size of MPS has been related with the appearance of events. A depressed post-stress left ventricular ejection fraction has a poor prognosis.
