潘生丁—^201Tl心肌灌注显像五年预后意义分析

选用Logistic回归对潘生丁-~(201)Tl心肌显像作了预后分析。在五年随访期间,41例受检者中有13例发生心肌事件,其中心因性死亡5例,心肌梗塞8例。结果提示潘生丁铊显像有明显的预后意义,异常显像将增加随后发生心肌梗塞或心因性死亡的危险性(O.R.=18.54)。暂时性多壁段缺损可进一步增加心脏事件的危险度。

5 years prognostic value of dipyridamole-thallium myocardial imaging

A prognostic study of dipyridamole- thallium myocardiac imaging was conducted with use of logistic regression. Over a 5 years follow- up period, cardiac events occurred in 13 patients within the 41 patients tested, death in 5 and myocardiac infarction in .8. The results of this study indicates that dipyridamole- thallium imaging has significant prognostic utility and that an abnormal scan increased the relative risk for the development of subsequent myocardial infarction or cardiac death (O.R. = 18.54). The presence of transient multiple thallium defects further increased the risk of a cardiac event. In conclusin, intravenous dipyridamole-thallium imaging is a potentially useful diagnostic test to determine the presence and severity of coronary diseases, and this noninvasive method is also beneficial for prognosis.
