The objective here was to investigate the SIndex and its modified form (MSIndex) to (1) report frequency of abnormal results in a population being investigated for PTE and (2) assess potential benefits in avoiding adverse outcome.<br \/>\nMethod(s): Retrospective analysis of 1505 CT pulmonary angiograms undertaken over a 12 month period. Abnormal SIndex was taken as outside limits 0.5-0.9. MSindex was calculated conventionally as heart rate divided by (2xdiastolic blood pressure+systolic blood pressure)\/3 and considered abnormal if &lt;0.7 or &gt;1.3. Analysis was on Excel.<br \/>\nResult(s): Mean age for the population was 67.7 (range 17-101) years. 337\/1505 (22.4%) scans showed PTE and of this population 19 patients had adverse outcome either died within 3 months (7 had malignancy) or requiring Intensive Care during the admission. For patients without PTE (n=1168), the SIndex was abnormal in 334(28.6%) and the MSindex in 293 (25.1%). For patients with PTE (n=337), respectively these figures were 89 (26.4%) and 68 (20.2%). Of those with adverse outcomes, 13\/19 Sindex and 17\/19 MSIndex values were not abnormal.<br \/>\nConclusion(s): Neither the SIndex not the MSIndex are discriminatory in helping distinguish the at risk groups with PTE and therefore cannot be used as an isolated criteria.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Type of publication: Conference abstract Author(s): *Abdulsamad S.P.; *Crawford E.; *Makan A.; *Ahmad N.; *Srinivasan K.; *Moudgil H.
