OBJECTIVES
We analyzed all-cause and coronary mortality as well as incident coronary heart disease (CHD) among the participants of the Turkish Adult Risk Factor Study, who resided essentially in the Marmara and Central Anatolia regions and were surveyed in the summer of 2007.

STUDY DESIGN
Information on the mode of death was obtained from first-degree relatives and/or health personnel of the local heath office. Most of the participants who were alive underwent physical examination and 12-lead electrocardiography. Incident CHD was defined as fatal or nonfatal myocardial infarction that occurred after the previous survey or incident stable angina and/or myocardial ischemia.

RESULTS
Of 1,618 participants to be surveyed, 961 were examined, 501 subjects were assessed based on information obtained, 18 men and 12 women were dead, and 52 subjects were lost to follow-up. The number of newly recruited subjects was 138. Addition of 3,010 person-years of follow-up raised the total follow-up of the survey to 48,500 person-years. Eight deaths were attributed to CHD; new coronary events were identified in 16 subjects. Annual mortality was estimated as 10.0 and coronary mortality as 2.7 per 1,000 adults. Overall mortality which was 11.2 per 1,000 person-years in the original cohort declined to 9.1 and 5.9 in more recently recruited 1997/98 and 2002/03 cohorts, respectively. In the age bracket of 45 to 74 years, all-cause mortality which was 15.2 in 2004 decreased to 10.2 per 1,000 person-years in the past three years (p=0.003), with a corresponding decrease in coronary mortality from 6.0 to 5.1 (p<0.18), indicating that the decreasing trend in overall mortality and coronary deaths observed in this age group in the previous years did not level off.

CONCLUSION
Our data show that the incidences of overall and coronary mortality continue to decline.
