Journal Title: Sultan Qaboos University Medical Journal - Year 2013, Vol 13, Issue 1
Abstract
Objectives: This study aimed to evaluate the epidemiology and coronary risk factors of acute coronary syndrome (ACS) in Oman. Methods: Data were collected through a prospective, multinational, multicentre survey of consecutive patients, hospitalised over a 5-month period in 2007 with a diagnosis of ACS, in Yemen and fve Arabian Gulf countries (Oman, Bahrain, Kuwait, Qatar, United Arab Emirates). Here we present data of Omani patients aged ≥20 years who received a provisional diagnosis of ACS and were consequently admitted to 14 different hospitals. Results: Tere where 1,340 confrmed ACS episodes in 748 men and 592 women (median age 61 years). Te overall crude incidence rate of ACS was 338.9 per 100,000 person-years (P-Y). Te age-standardised rate (ASR) of ACS was 779 and 674 per 100,000 P-Y for men and women, respectively. Te ASR male-to-female rate ratio was highest in the ST-elevation myocardial infarction (STEMI) group (2.26, 95% confdence interval ([CI], 1.63 to 3.15) followed by the non-STEMI (NSTEMI) group (1.68, 95% CI 1.28 to 2.21) and unstable angina (0.79, 95% CI 0.66 to 0.99). Unstable angina accounted for 55%, STEMI for 26% and NSTEMI for 19% of ACS cases. Among the coronary risk factors, there was a high prevalence of hypertension (68%), diabetes mellitus (DM) (36%), hyperlipidaemia (63%), and overweight/obesity (65%), with a relatively low rate of current tobacco use (11%). Conclusion: Our study confrms a high incidence of ACS in Omanis and supports the notion that the cardiovascular disease epidemic is also sweeping developing countries.
