Data Submission stage

Syncope - use 'syncope' code, not 'loss of consciousness'. Leg Pain on Walking - add "(Claudication)" to clarify questionnaire. Use 'claudication' SNOMED CT code. BUT --- do we make any effort to verify a cause at this point? If not, a much more general 'pain on walking' 426899007 might be appropriate. Left or Right sided weakness - 50582007, can't distinguish which side. Slurred speech - 289195008 Other - need mechanism to review the free text entries and consider adding to q'aire and also to ontology retrospectively

Diagnosis STEMI - 401303003 (because it's a disorder code, rather than the more specific 'ECG finding' codes) ACS - 394659003 (with additional code - 444931001 - if troponin positive) * note this is relevant only for as long as the test we use is trop I. There's an alternative UK specific code for 'cardiac troponin positive' - 372851000000101 - in TB's spreadsheet, which might be better. There's also a 'cardiac troponin negative code - 372901000000105. Stent thrombosis - 421327009 - not a clear mechanism for differentiating between acute and chronic, and no mention in q'aire of the 'immediate' phase. Perhaps best to just group all thromboses and leave the differentiation for the study Intermittent claudication - 63491006 Arterial occlusion - 2929001 (very general code) Cardiac arrest - 410429000 Done as far as ruptured aortic aneurysm. Start next meeting at ventricular ectopics.

23.8.2011 Vent ectopics: 17338001 - disorder, rather than finding Atrial ectopics: 406461004 Infective endocarditis is 233850007, need additional codes post-coordinated for specific structure: aortic (34202007 - structure - or 8722008 - disorder), mitral (91134007 or 11851006) or pulmonary (39057004 or 76267008). So, structure or disorder? Viral pericarditis 70189005 Bacterial pericarditis 233883000 post-infarction pericarditis 233885007 - i.e. early post-infarction not Dressler's syndrome other pericarditis 3238004 SVT: 6456007 VT: 25569003 VF: 71908006 Thrombotic Stroke or CVA 230690007 - worth double checking this with Sadat and Muntaser, as it's not a code they proposed. Haemorrhagic stroke 230706003 Restrictive cardiomyopathy 415295002 Ischaemic Cardiomyopathy 194849004 - suggest this to Sadat / Muntaser, see synonyms Dilated Cardiomyopathy 399020009 (congestive cardiomyopathy, but with 'dilated' as a synonym) or 20529002

(secondary dilated cardiomyopathy, a child of the previous code). Which is better? Ask Muntaser and Sadat.
