Epidemiology of Acute Coronary Syndrome in Kermanshah

Introduction: Coronary artery disease is one of the most dangerous health problems in developed and undeveloped countries. Annually one million patients admitted in coronary care units in U.S.A due to AMI and about 59 million people suffered from Atherosclerosis. In Europe 54% of C.C.U admissions is due to non Q wave MI and 46% due to Q wave MI. Unfortunately there is no distinct statistic al results concerning the incidence of acute coronary syndrome in Iran.

Materials and Methods: This study was carried out to determine prevalence and incidence of acute coronary syndrome during 2002 –5 in Imam Ali Hospital of Kermanshah. Calculated sample size was 621 patients, of whom, all clinical and demographic data were collected. λ² and T-Test were used to analyse the data.

Results: 843 patients profiles were studied, 607 males and 236 females aged between 25 to78 years old. . The study showed; 312 patients with unstable angina, 453 patients with Q wave myocardial infarction and 78 patients with non-Q wave myocardial infarction.  Incidence and prevalence of acute coronary syndrome were U.A 37%, non-Q wave MI 9.2% and Q wave MI 53.7% respectively.

Conclusion: More different incidence and frequency of A.C.S was observed than those reported by developed countries (e.g. 9.2% non Q wave MI vs. 54%). Further studies needed to be done to find different prevalence of ACS in Kermanshah.
