1.  Design and Rationale of Gulf locals with Acute Coronary Syndrome Events (Gulf Coast) Registry 
To describe the risk profile, management and one-year outcomes of patients hospitalized with acute coronary syndrome (ACS) in the Gulf region of the Middle East.
Subjects and Methods:
The Gulf locals with acute coronary syndrome events (Gulf COAST) registry is a prospective, multinational, longitudinal, observational, cohort-based registry of consecutive citizens, from the Gulf region of the Middle East, admitted from January 2012 to January 2013 to 29 hospitals with a diagnosis of ACS. Data entered online included patient demographics, cardiovascular risk profiles, past medical history, physical findings on admission, in-hospital diagnostic tests and therapeutic management, as well as one year outcomes.
3188 patients were recruited. The mean age was 60.4 ┬▒ 12.6years (range: 22-112), 2104 (66%) were males and 1084 (34%) females. The discharge diagnosis was ST-segment elevation myocardial infarction (STEMI) in 741 (23.2%), new-onset left bundle branch block myocardial infarction (LBBBMI) in 30 (0.9%), non-ST-segment elevation myocardial infarction (NSTEMI) in 1486 (46.6%) and unstable angina in 931 (29.2%). At hospital presentation, 2105 (66%), 1779 (55.8%), 1703 (53.4%) and 740 (23.2%) had history of hypertension, dyslipidemia, diabetes mellitus and active smoking, respectively.
Patients with ACS in our region are young with very high risk profile. The Gulf COAST registry is an example of successful regional collaboration and will provide information on contemporary management of ACS in the region.

2.  Clinical Characteristics and Outcomes of Patients with Acute Coronary Syndrome and Prior Coronary Artery Bypass Grafting in a Large Middle Eastern Cohort 
Acute Coronary Syndrome (ACS) can occur in patients with prior coronary artery bypass grafting (CABG). In the Gulf Registry of acute coronary events (Gulf RACE), we identified the clinical characteristics and in-hospital outcomes of these patients.
Clinical characteristics and in-hospital outcomes for 461 ACS patients with prior CABG are compared to 7715 ACS patients without prior CABG enrolled from 64 hospitals in 6 Gulf countries over a 6-month period.
The overall incidence of ACS with prior CABG was 5.6% out of 8176 patients. The ACS with prior CABG were older (63 vs 55 years, P<0.0001), had more history of diabetes (62.3 vs 37.6%, P <0.0001), dyslipidemia (70.3 vs 29.5%, P<0.0001), and hypertension (75.7 vs 47.8%, P<0.0001) compared with the non-CABG group. They presented more frequently with dyspnea (14.8 vs 9.5%, P<0.0005), non-ST segment elevation myocardial infarction (41.4 vs 31.6%, P<0.0001) and echocardiographic evidence of left ventricular dysfunction (49.4 vs 29.8%, P<0.0001) than ACS without prior CABG. They had a complicated in-hospital course with more recurrent ischemia (13.9 vs 9.3%, P=0.0011), heart failure (24.1 vs 15.7%), and stroke (2.2 vs 0.6%) compared with those without CABG. The in-hospital mortality rate was 5.6% in the CABG group compared with 3.5% in the ACS without prior CABG group. After adjusting for confounders, prior CABG was independently associated with recurrent ischemia and shock, more in patients presenting with ST elevation than non-ST elevation ACS.
Patients with ACS and prior CABG are a high-risk group with poor outcomes irrespective of their older age and comorbidities. They should be identified and treated differently to improve their outcomes.
