Abstract
This study aimed to evaluate the epidemiology and coronary risk factors of acute coronary syndrome (ACS) in Oman. 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 five 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. There where 1,340 confirmed ACS episodes in 748 men and 592 women (median age 61 years). The overall crude incidence rate of ACS was 338.9 per 100,000 person-years (P-Y). The age-standardised rate (ASR) of ACS was 779 and 674 per 100,000 P-Y for men and women, respectively. The ASR male-to-female rate ratio was highest in the ST-elevation myocardial infarction (STEMI) group (2.26, 95% confidence 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%). Our study confirms a high incidence of ACS in Omanis and supports the notion that the cardiovascular disease epidemic is also sweeping developing countries.Keywords
