Goes up with age
Numbers are approximate: (all comers)
<1980: 20 % mortality
1990: (with thrombolysis):10-15%
2000: (with pci):5-10%
2010: (with drug eluting stents
the sooner one arrives, the lower the mortality.
Age, lung, kidney and cerebrovascular disease increase mortality. Age is a factor but not as much as the above.
