Abstract 67: Secular Trends in Cardiovascular Comorbidities and Associated Mortality Among Patients Hospitalized Alive After Out-of-Hospital Cardiac Arrest: A 20-Year Experience from a Middle-Eastern Country (1991-2010)
Objectives: little is known about the trends of the cardiovascular comorbidities associated with cardiac arrest in the developing countries and how they affect mortality. This was examined in this study in patients hospitalized alive after out of hospital cardiac arrest in a real-world population in a Middle-Eastern Country.
Methods: Retrospective analysis of prospective registry of all patients hospitalized alive after out of hospital cardiac arrest 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 801 patients were hospitalized alive after out of hospital cardiac arrest; 577 men and 224 women. In the latter years of the study there was 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 trending higher. The study also demonstrated an increasing trend of in-hospital mortality over the 20-year period [table].
Conclusions: recent improvements in the recognition and management of the cardiovascular comorbid conditions associated with cardiac arrest, especially acute coronary syndromes and heart failure were at least in part, offset by the increase in prevalence of diabetes mellitus and hypertension along with ischemic heart disease in our region. Tailored strategies for the prevention and treatment of these conditions are warranted to reduce the burden of cardiovascular disease and its related mortality.
