Abstract 108: Ethnic Differences among Middle Eastern Arab and South Asian Patients Hospitalized With Acute Coronary Syndromes Complicated by In-Hospital Cardiac Arrest: A 20-Year Experience From a Middle-Eastern Country (1991-2010)
Objectives: Data is lacking about ethnic differences in in-hospital cardiac arrest (IHCA) complicating acute coronary syndromes (ACS). The aim of this study was to compare the incidence, clinical characteristics, management and outcome of Middle Eastern Arabs compared to South Asian patients with IHCA complicating ACS hospitalization using a 20-year national registry from a Middle-Eastern Country in which these two ethnicities are prevalent.
Methods: Retrospective analysis of all patients hospitalized with ACS that developed IHCA in Qatar from 1991 through 2010 was made. Patients were compared according to ethnicity. Clinical characteristics, management and outcomes were analyzed.
Results: During the 20-years period 7108 Arab and 7485 South Asian patients were hospitalized with ACS in Qatar from 1991 to end of 2010. Of these 752 patients developed IHCA during hospitalization; 482 Arabs and 270 Asians with an incidence rate of 6.8% and 3.6%, respectively; p= 0.001. Arabs with IHCA were 14 years older and had a significantly higher prevalence of hypertension, diabetes mellitus, chronic renal impairment and prior myocardial infarction while current smoking status was significantly more common in Asians. Arabs with IHCA were significantly less likely to receive thrombolysis but more likely to undergo coronary artery bypass surgery compared to Asians. Arabs had a significantly longer hospital stay compared to Asians but the in-hospital mortality and stroke rates were comparable between the two groups [table].
Conclusions: Our study demonstrates that Arabs in our region have a higher incidence of IHCA complicating ACS hospitalizations compared to Asians. Arabs had a higher prevalence of cardiovascular co-morbidities with the exception of smoking which was more common in Asians. The current study underscores the need to study IHCA and ACS in other ethnicities.
