Incidence and survival
Most studies indicate that the incidence of heart attack is falling in the UK – on average by about 2% per year in men and women under the age of 70. In addition, survival after a heart attack is improving: 28-day case fatality for heart attack is falling on average by about 1.5% per year in men and women under about the age of 70 in the UK.
Prevalence
It is often stated that prevalence of a previous heart attack must be increasing because case fatality is falling, i.e. with declining case fatality there must be an increasing number of people who have had a heart attack in the past. However since incidence of heart attack is also falling, it remains possible that the effect of the decline in incidence outweighs the effect of the decline in case fatality and that prevalence is falling too.
Longitudinal data from the General Household Survey show that since 1988 there has been no marked change in the overall rate of self-reported morbidity from a previous heart attack. However, rates of self-reported longstanding cardiovascular disease have increased in older age groups since 1988: by around 35% in those aged 65-74 and 27% in those aged 75 and over.
