The following table provides data from the East of England strategic health authority (SHA) (which includes West Chelmsford constituency). We are unable to break the data down into individual constituencies. The East of England strategic health authority was formed in 2006-07 by a merger of Norfolk, Suffolk and Cambridgeshire; Essex; and Bedfordshire and Hertfordshire. Figures for 2003-04 to 2005-06 were calculated by summing these three together. It shows the number of males under the age of 35 years old who were admitted to hospital due to a heart attack:

Finished admission episodes
East of England SHA( 1) England
2007-08 47 348
2006-07 40 343
2005-06 48 369
2004-05 43 368
2003-04 37 335
(1) Norfolk, Suffolk and Cambridgeshire; Essex; and Bedfordshire and Hertfordshire prior to 2006-07


Finished admission episodes:

A finished admission episode is the first period of inpatient care under one consultant within one healthcare provider. Finished admission episodes are counted against the year in which the admission episode finishes. Admissions do not represent the number of inpatients, as a person may have more than one admission within the year.

Primary diagnosis:

The primary diagnosis is the first of up to 20 (14 from 2002-03 to 2006-07 and 7 prior to 2002-03) diagnosis fields in the Hospital Episode Statistics (HES) data set and provides the main reason why the patient was admitted to hospital.

The ICD-10 codes used to identify heart attacks are as follows:

I21—acute myocardial infarction

I22—subsequent myocardial infarction

Number of episodes in which the patient had a (named) primary diagnosis:

These figures represent the number of episodes where the diagnosis was recorded in the primary diagnosis field in a HES record.

Data quality:

HES are compiled from data sent by more than 300 national health service trusts and primary care trusts (PCTs) in England. Data are also received from a number of independent sector organisations for activity commissioned by the English NHS. The NHS information centre for health and social care liaises closely with these organisations to encourage submission of complete and valid data and seeks to minimise inaccuracies and the effect of missing and invalid via HES processes. While this brings about improvement over time, some shortcomings remain.
