throughout the world
Epidemiology of IHD
6.3 million suffer on acute MI each year globally
In USA, 800,000 people experience AMI and
213,000 die yearly from CHD.
In UK, 300,000 people have AMI and 150,000 die
from CHD yearly
In Bangladesh, the prevalence of CHD was
estimated as 3.3/1000 in 1976 and 17.2/1000 in
And In 2011 it was 51/ 1000
Stable Angina Pectoris
