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.

Valve surgery 73544002
TAVI - skip, there is a code for 'valve implantation', and a code for 'transaortic approach'.
PPCI: 414089002
ICD implantation: 395218007
thrombolysis: 426347000
ablation of lesion of heart: 10683007
coronary angiography 33367005

Done to here, just measurements to finish this section.
