age-adjusted death rates for chd have steadily
decreased nearly every year since 1980.

in 1989,
after ���ve years, coronary
artery bypass grafting
(cabg) was more effective
than percutaneous
coronary intervention
(pci) at relieving angina
(84% vs. 79%), and
fewer patients required
revascularization (9.8%
vs. 40.1%) post-procedure.
from 249.6 in 1990
to 194.6 in 1999,
patients undergoing pci
have half the risk of stroke
(0.6%) compared with
cabg (1.2%), but the
difference in the 10-year
survival rate is less
than 1%.
and from 186.8

in 2008.
despite the long-term
ef���cacy of cabg, utilization
of this more expensive
procedure has declined
while pci has remained
relatively stable.
