Letter from Karen Dunnell, dated November 2008:
As National Statistician, I have been asked to reply to your recent question asking how many deaths in Crosby constituency resulted from heart disease in (a) 1997 and (b) 2008 to date.(236703)
There were (a) 192 deaths in Crosby parliamentary constituency1 where ischaemic heart disease was the underlying cause of death2 in 1997, and (b) 121 deaths in 20073 which is the latest year available.
1 Based on boundaries as of 2008.
2 Cause of death for ischaemic heart disease was defined using the International Classification of Diseases, Ninth Revision (ICD-9) codes 410-414 for 1997 and Tenth Revision (ICD-10) codes 120-125 for 2007. The introduction of ICD-10 in 2001 means that the number of deaths from this cause before 2001 are not completely comparable with later years.
3 Figures are for deaths registered in each calendar year.
