OBJECTIVES
We analyzed the distribution of cumulative all-cause and cardiovascular mortality and incident coronary heart disease (CHD) across the seven geographic regions of Turkey and presented overall and coronary mortality findings of the 2010 survey of the Turkish Adult Risk Factor Study.

STUDY DESIGN
A total of 1406 participants were surveyed. Information on the mode of death was obtained from first-degree relatives and/or health personnel of local heath offices. Information on survivors was obtained from history, physical examination, and 12-lead electrocardiography.

RESULTS
Of the surveyed participants, 686 were examined; information on health status was obtained in 577 subjects, and 32 participants (14 women, 18 men; mean age 72.3±15.6 years) were ascertained to have died. The total duration of follow-up was 2,520 person-years. Nineteen deaths were of coronary (n=16) or cerebrovascular (n=3) origin. Cumulative 20-year assessment of the entire cohort for the age bracket of 45-74 years disclosed a high coronary mortality rate, being 7.4 and 4.1 per 1000 person-years in men and women, respectively, and representing a limited decline after year 2000. Age-adjusted Cox regression analysis comprising 433 deaths and 506 incident CHD cases over a 7.3-year follow-up showed similar mortality rates across the regions, and a significantly high CHD incidence in males of the Black Sea and Marmara regions and in females of the Southeast Anatolia. Currently, 480,000 incident CHD cases are estimated yearly in Turkey.

CONCLUSION
The high age-adjusted overall mortality in Turkey shows nonsignificant differences across geographic regions, whereas the age-adjusted CHD incidence is high in the Black Sea and Marmara regions.
