    Analysis of all-cause mortality and coronary events in the Turkish Adult Risk Factor Survey 2005
    (Turkish Soc Cardiology, 2006) Onat, Altan; Karabulut, Ahmet; Esen, Ali Metin; Uyarel, Huseyin; Ozhan, Hakan; Albayrak, Sinan; Keles, Ibrahim
    Objectives: To analyze all-cause and coronary mortality as well as newly diagnosed coronary heart disease (CHD) in the cohort of the Turkish Adult Risk Factor Study which was surveyed in the summer of 2005 and included individuals residing essentially in the regions of Marmara and Central Anatolia. Study design: Information on the mode of death was obtained from first-degree relatives and/or health personnel of local health offices. Diagnosis of coronary heart disease was based on history, physical examination, and 12-lead electrocardiograms. New coronary events were defined as those that developed after the last survey, including fatal or nonfatal myocardial infarction, stable angina and/or myocardial ischemia. Results: Of 1646 participants, 1078 subjects (mean age 54.8 +/- 11.8 years) were examined; information alone was gathered for 507 subjects; 43 subjects (28 men, 15 women) had died, and 18 subjects were lost to follow-up. Incorporation of 3104 person-years of follow-up raised the total follow-up of the survey to 42,600 personyears. Twenty-three deaths were classified as CHD-related. New coronary events were identified in 37 participants. Annual mortality and coronary mortality rates were 13.9 and 7.4 per 1000 adults, respectively. Overall mortality per 1000 person-years was 16.3 in rural areas and 12.0 in urban areas. The high share of coronary deaths among all deaths persisted. In the age bracket of 45 to 74 years, overall mortality declined to 10.6 (p= 0.09) and coronary mortality to 5.5 per 1000 person-years, thus supporting the presence of a consistently decreasing trend of all-cause mortality and coronary mortality. Estimated fatal and nonfatal new coronary events appeared to be high with 18 per 1000 person-years. Conclusion: A rising trend persists in the incidence of coronary mortality and its share in overall mortality as well as in new coronary events. The occurrence of coronary deaths among women seems to be gradually shifting to older ages.

    Independent prediction of metabolic syndrome by plasma fibrinogen in men, and predictors of elevated levels
    (Elsevier Ireland Ltd, 2009) Onat, Altan; Ozhan, Hakan; Erbilen, Enver; Albayrak, Sinan; Kucukdurmaz, Zekeriya; Can, Guenay; Keles, Ibrahim
    The role of plasma fibrinogen levels in predicting metabolic syndrome (MetS) and assessment of determinants of these levels were investigated. A total of 2234 men and women, aged 49 +/- 12 years, representative of Turkish adults who had plasma fibrinogen determinations, were prospectively evaluated and followed for a mean of 6.6 years. The modified Clauss method was used for assays. MetS was defined by ATPIII criteria modified for male abdominal obesity. MetS cases at baseline were excluded in prospective analyses. Median (interquartile range) fibrinogen values were 2.87 (2.29; 3.56) g/L. Fibrinogen levels predicted significantly newly developing MetS in men (RR 1.40 [95%CI 1.07; 1.83] for a 2-fold increment), after adjustment for age and smoking status, and (RR 1.32 [95%CI 0.95; 1.83] again for doubling), after additional adjustment for all 5 components of MetS. MetS was not significantly predicted by fibrinogen levels in women in either multivariable model. By regression analysis of eight covariates, not waist circumference, but systolic blood pressure, current smoking and C-reactive protein (CRP) in men, and age in women were predictors of elevated (>3.0 g/L) fibrinogen at follow-up (p<0.05 in all). Conclusions: Plasma fibrinogen predicts MetS independently of its components in men, in contradistinction to women, and, hence, is likely one of its components. Hyperfibrinogenemia representing an inflammatory state is postulated as the underlying mechanism. Central obesity is linked to elevation in fibrinogen mainly through the mediation of blood pressure, CRP, and via being affected by cigarette smoking.
