Baseline characteristics, management practices, and long-term outcomes of middle eastern patients in the second gulf registry of acute coronary events [Gulf RACE-2]

Limited data are available on patients with acute coronary syndromes [ACS] and their long-term outcomes in the Arabian Gulf countries. We evaluated the clinical features, management, in-hospital, and long-term outcomes of in such a population. A 9-month prospective, multicenter study conducted in 65 hospitals from 6 countries that also included 30 day and 1-year mortality follow-up. ACS patients included those with ST-elevation myocardial infarction [STEMI] and non-ST-elevation acute coronary syndrome [NSTEACS], including non-STEMI and unstable angina. The registry collected the data prospectively. Between October 2008 and June 2009, 7930 patients were enrolled. The mean age [standard deviation], 56 [17] years; 78.8% men; 71.2% Gulf citizens; 50.1% with central obesity; and 45.6% with STEMI. A history of diabetes mellitus was present in 39.5%, hypertension in 47.2%, and hyperlipidemia in 32.7%, and 35.7% were current smokers. The median time from symptom onset to hospital arrival for STEMI patients was 178 minutes [interquartile range, 210 minutes]; 22.3% had primary percutaneous coronary intervention [PCI] and 65.7% thrombolytic therapy, with 34% receiving therapy within 30 minutes of arrival. Evidence-based medication rates upon hospital discharge were 68% to 95%. The in-hospital PCI was done in 21% and the coronary artery bypass graft surgery in 2.9%. The in-hospital mortality was 4.6%, at 30 days the mortality was 7.2%, and at 1 year after hospital discharge the mortality was 9.4%; 1-year mortality was higher in STEMI [11.5%] than in NSTEACS patients [7.7%; P<.001].Compared to developed countries, ACS patients in Arabian Gulf countries present at a relatively young age and have higher rates of metabolic syndrome features. STEMI patients present late, and their acute management is poor. In-hospital evidence-based medication rates are high, but coronary revascularization procedures are low. Long-term mortality rates increased severalfold compared with in-hospital mortality

Regional variability in hospital mortality in patients hospitalized with st-segment elevation myocardial infarction: findings from the gulf registry of acute coronary events

To study the short-term mortality from ST-segment elevation myocardial infarction [STEMI] in the Arabian Gulf region of the Middle East, and to examine whether these geographically and culturally related countries had similar or different outcomes. The Gulf Registry of Acute Coronary Events recruited consecutive acute coronary syndrome patients from six Middle Eastern countries over a 5-month period. Of 6,706 patients recruited, 2,626 [39%] had STEMI, and a total of 165 patients died in hospital, with a crude mortality rate of 6.3%. However, mortality rates varied geographically between 10% in Yemen, 9.6% in Oman and 3.3% in the other countries. The unadjusted odds ratio of mortality for Yemen was 3.2 [95% CI: 2.2-4.7], and 3.1 [95% CI: 1.9-4.8] for Oman, compared to other Gulf countries. Even after adjusting for age and gender, the mortality remained significantly higher, almost double, in Oman and Yemen compared to other countries. This could be understood in the light of significant differences in a number of practice pattern variables such as reperfusion therapy, timely presentation and use of evidence-based medications. We found significant variability in STEMI mortality among Gulf Arab countries and identified areas requiring further efforts to reduce excess mortality in the region
