Acute myocardial infarction (MI) is one of the common causes of morbidity and mortality all over
the world. The mortality of (MI) started to decrease during the last 10 years, because of changing
life style, reduction of coronary risk factors, improvement of medical care and effective treatment.
To compare the mortality rate of acute MI in 1989, 1990 (before sanction), 1999, 2000 (after
sanction, but before availability of thrombolytic therapy), 2001 and 2002 (after availability of
thrombolytic therapy).The study showed that the incidence of acute myocardial infarction
increased, but the mortality rate significantly decreased in 2001 and 2002 (P<0.0% and P<0.01
respectively). In this study the incidence of acute (MI) was significantly higher in men (P<0.05),
but there was no significant difference in the mortality between men and women.The mortality rate
of acute (MI) was significantly higher in older age groups, 61-70 and >70 years old (P<0.05 and
P<0.01 respectively). Diabetic and hypertensive patients had higher mortality rate from acute MI.
The study showed that acute MI was more common during winter, but the mortality rate was
significantly higher during summer (P<0.05). The incidence of acute MI increased in 2001 and
2002, but its mortality rate significantly reduced. Acute MI is more common in men, but the
mortality is slightly higher in women. Mortality rate of acute MI is higher in older ages, diabetic
and hypertensive patients. The incidence of acute MI is higher during winter, but the mortality rate
is higher during summer. |
