Abstract 245: Secular trends of Cardiovascular Comorbidities and Associated Mortality among Patients With In-hospital Cardiac Arrest: a 20-year Experience From Qatar (1991-2010)
Objectives: Little is known about the trends of in-hospital cardiac arrest (IHCA) mortality and associated cardiovascular comorbidities in the developing countries. This was examined in this study of a 20-year prospectively collected registry of all patients hospitalized with acute cardiac events in a Middle-Eastern Country.
Methods: Retrospective analysis of all patients that developed IHCA in Qatar from 1991 through 2010 was made. Rates and trends of cardiac comorbidities and in-hospital mortality were examined.
Results: During the 20-years period 41,436 patients were hospitalized with acute cardiac disease in Qatar From 1991 to end of 2010. Of these 1684 patients (4.06%) developed IHCA. In the latter years of the study there was a significant increase in the prevalence of diabetes mellitus and hypertension when compared to patients hospitalized in the earlier years. Associated ischemic heart disease and heart failure were also significantly trending higher. The study demonstrated an increasing rate of in-hospital mortality of patients with IHCA over the 20-year period that peaked in the period (1999-2002).
Conclusions: Our study demonstrated that the poor survival after IHCA was associated with an increase in the prevalence of cardiovascular comorbidities in our patients. Tailored strategies for the prevention and treatment of these conditions are warranted to reduce the burden of cardiovascular disease and its related mortality in our region.
