ischaemic heart disease (IHD)
Epidemiology:
general points:
also referred to as coronary artery disease (CAD)
incidence of coronary events = rate of occurrence of totality of fatal & non-fatal events
strictly speaking incidence should refer only to 1st event not recurrences but these are often lumped together in which case should be referred to as event rates
mortality from coronary heart disease is usually measured as annual umber deaths per 100,000 pop.
case fatality = risk of death after an event (ie. proportion who die within a set period after an event)
USA:
1 million deaths per year = 50% of all deaths
160,000 deaths occurred in people < 65 yrs old (45% of all AMI's occur in this age group)
2/3rds of sudden deaths ffrom IHD occur outside hospital & usually within 2hrs of onset of symptoms
>50% are women
5 million years of potential life is lost per year due to cardiovascular disease & costs > $US100b/year
there has been a 54% reduction in age-adjusted mortality from IHD from 220/100,000 pop. in 1963 to 101/100,000 pop. in 1990:
25% fall in incidence
25% fall in case fatality rate:
30% mortality pre-CCUs
15% mortality post-CCUs
12.5% mortality post-CCUs with emphasis on decreasing MVO2
5% mortality with introduction of thrombolytic therapy
