The mortality rate for myocardial infarctions is what?

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):2-5% 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.
