Coronary Heart Disease
Incidence
The incidence rate for coronary heart disease (CHD) is the number of new cases of CHD per 100,000 population. New cases are defined to be hospital admissions or deaths, with no prior hospital admission for CHD in the previous 10-year period.
Key points:
-
Incidence (new cases) of CHD has also been decreasing over the past decade. The number of acute myocardial infarctions (heart attacks) has decreased from 14,003 per year in 1999/00 to 10,415 in 2007/08 but increased to 11,294 in 2008/09. The recent increase is due to the change in the clinical definition of AMI, based on more sensitive tests - i.e. troponin. (see Table IC1 ).
-
Between 2007/08 and 2008/09 the incidence rate for CHD (total number of people diagnosed with CHD per 100,000 population, standardised by age and sex) decreased by 5.6%. (from 310.9 cases per 100,000 population for 2007/08 to 293.5 cases per 100,000 population in 2008/09 (see Table IC1 ).
-
Incidence is related to age - the rate for under 75s in 2008/09 is 218.0 per 100,000 and for over 75s for the same period 2107.2 per 100,000 (see Table IC1 ).
-
Coronary heart disease incidence rates are consistently higher for males than females across all age groups (see Table IC1 ).
