Article Age at Death in the Turkish Adult Risk Factor Study: Temporal Trend and Regional Distribution at 56.700 Person-years' Follow-Up(Turkish Soc Cardiology, 2009) Onat, Altan; Ugur, Murat; Tuncer, Mustafa; Ayhan, Erkan; Kaya, Zekeriya; Kucukdurmaz, Zekeriya; Kaya, HasanObjectives: We analyzed the temporal trend and regional distribution of age at death due to all-causes and the sex-specific and age range defined by coronary mortality in the 18-year follow-up of the Turkish Adult Risk Factor Study. Study Design: The participants of the Turkish Adult Risk Factor Study who have been examined in even years were last surveyed in August 2008. A total of 1,582 individuals were surveyed, which constituted half of the surviving participants of the overall cohort. Information on death was obtained from first-degree relatives and/or health personnel of local health offices. Survivors were evaluated by history, physical examination, and 12-lead electrocardiography. The cumulative follow-up was 56,700 person-years. Results: Of 1582 participants, 868 (431 men, 437 women) were examined, in 604 subjects information was gathered, and 47 participants (26 men, 21 women) were ascertained to have died. Twenty-two deaths were classified as being of coronary origin. Cumulative assessment of the entire cohort in the age range of 45-74 years disclosed coronary mortality to be 7.64 per 1000 person-years in men and 3.84 in women and persisted to be the highest among 30 European countries, whereas overall mortality declined at a greater proportion. Overall mean ages at death were deferred within a 12-year period by 7.4 years in men and 6 years in women, to 71.9 and 74.8 years, respectively. The extension of this mean survival was similar among urban-rural areas and geographic regions. Conclusion: Coronary mortality declined modestly, but life expectancy of Turkish adults rose by a mean of nearly seven years in the 12 years to 2003-08 without showing major differences in sex, urban-rural dwelling or geographic regions.Article External Iliac Artery Pseudo-Stenosis Associated With Catheterization: Report of Two Cases(Termedia Publishing House Ltd, 2012) Karapinar, Hekim; Gul, Ibrahim; Kucukdurmaz, Zekeriya; Gumrukcuoglu, Hasan Ali; Yilmaz, AhmetIn invasive cardiology practices, the most commonly used vascular access site is the femoral artery. Atherosclerotic stenoses on the femoral and iliac arteries create difficulties in these practices. Vasospasm rarely occurs on large arteries like these. This paper reports stenosis encountered during coronary angiography on iliac arteries in 2 patients. The stenoses caused difficulties for guidewire and catheter insertion in catheterization. In the revisualization of these arteries at the next session, the stenoses had disappeared, but the arteries were tortuous. The patients did not have peripheral ischemia signs previously, nor did they appear after the procedure. These transient stenoses might have occurred due to vasospasm and the accordion effects caused by the guidewire and/or catheter.Article Is Atrial Electromechanical Coupling Delayed in Patients With Secundum Atrial Septal Defect(Wiley-blackwell, 2013) Oflaz, Mehmet Burhan; Karapinar, Hekim; Kucukdurmaz, Zekeriya; Guven, Ahmet Sami; Gumrukcuoglu, Hasan Ali; Sarikaya, Savas; Yilmaz, AhmetBackground: There is no available published information about the atrial electromechanical coupling time (AEMCT) in patients with atrial septal defect (ASD). The aim of this study was to investigate the relationship between ASD and AEMCT obtained by tissue Doppler imaging (TDI). Methods: A total of 35 patients with ASD and 22 healthy controls were included in the study. The time intervals from the onset of the P-wave on the surface electrocardiogram to the beginning of the late diastolic A-wave (PA) representing AEMCT were obtained from the lateral mitral annulus, septal mitral annulus, and right ventricular (RV) tricuspid annulus, and named PA-lateral, PA-septal, and PA-tricuspid, respectively. The difference between PA-septal and PA-tricuspid, PA-lateral and PA-septal, and PA-lateral and PA-tricuspid were defined as intra-right AEMCT, intra-left AEMCT, and inter-AEMCT, respectively. Results: PA-tricuspid, PA-septal, and PA-lateral values were longer in patients with ASD when compared with the controls, but did not reach statistical significance (39.9 +/- 19.1 vs. 37.2 +/- 15.5, P = 0.952; 49.6 +/- 14.0 vs. 45.4 +/- 11.1, P = 0.826 and 60.3 +/- 16.3 vs. 59.7 +/- 12.5, P = 0.437, respectively). There were no significant differences between the ASD and control groups in terms of inter-atrial, intra-right atrial, and intra-left AEMCT (21.3 +/- 2.3 vs. 20.8 +/- 4.6, P = 0.957; 9.7 +/- 3.3 vs. 6.9 +/- 1.3, P = 0.723 and 13.6 +/- 4.7 vs. 10.9 +/- 4.5, P = 0.518, respectively). Furthermore, ASD diameter and total septum length did not correlate with AEMCT. Conclusion: Both intra-and inter-AEMCT were not increased in patients with ASD than control subjects. In addition, we found no association between the ASD diameter and indices of AEMCT in patients with ASD.Article Long Coronary Artery Aneurysm Treated by Two Graft Stents on a Single Bare Metal Stent Scaffold(Termedia Publishing House Ltd, 2012) Karapinar, Hekim; Kucukdurmaz, Zekeriya; Gumrukcuoglu, Hasan Ali; Yilmaz, AhmetWe report a case of a 61-year-old male who presented with symptoms of stable angina The coronary angiography revealed a long aneurysm and significant stenosis after the aneurysmatic segment on the circumflex artery. The length of the aneurysm was 21 mm with the largest diameter 9 mm. We thought that single graft stent placement was not possible due to the angled circumflex artery, length of the aneurysm and inflexible nature of graft stents. Distal stenosis was stented as usual. A bare metal stent was implanted over the aneurysm from normal to normal segments. Two graft stents were implanted sequentially in the aneurysm over the bare metal stent scaffold. Stent grafts covered the aneurysm without any main side branch occlusion. The patient was discharged the next day without any complications. The patient was asymptomatic after two years of follow-up with usual medications.Article Mortality and Coronary Events in the Turkish Adult Risk Factor Survey 2006: Mortality Is Declining in Women Whereas Overall Prevalence of Coronary Heart Disease Is on the Incline(Turkish Soc Cardiology, 2007) Onat, Altan; Albayrak, Sinan; Karabulut, Ahmet; Ayhan, Erkan; Kaya, Zekeriya; Kucukdurmaz, Zekeriya; Tuncer, MustafaObjectives: We analyzed all-cause and coronary mortality, incidence and prevalence of coronary heart disease (CHD) in a cohort of the Turkish Adult Risk Factor Study which was surveyed in the summer of 2006 essentially in geographic regions other than Marmara and Middle Anatolia. Study design: The survey consisted of 1585 participants (776 men, 809 women; mean age 55.3 +/- 11.8 years), accounting for 49% of all living participants of the overall cohort. Information on death was obtained from first-degree relatives and/or health personnel of local health offices. Survivors were evaluated by history, physical examination, and 12-lead electrocardiography. New coronary event was defined as fatal or nonfatal myocardial infarction, new stable angina, and/or myocardial ischemia that had occurred after the former survey. Results: Of the participants, 946 were examined, 599 subjects were evaluated on the basis of information gathered, and 40 deaths ( 27 men, 13 women) were documented. Cumulative follow-up of the survey starting from 1990 increased to 45,490 person-years with the addition of 2,842 person-years. Fifteen deaths were attributed to CHD. Annual overall mortality and coronary mortality rates were 14.1 and 5.1 per 1000 adults, respectively. In the 45 to 74 years age bracket, overall mortality declined to 10.9 (p=0.09) and coronary mortality to 5.6 per thousand. A decreasing trend in mortality was pronounced in women. The mean age at death increased to 67.1 years in men, and to 75.9 years in women. The prevalences of CHD were found to be 3%, 11%, and 27% in age groups of 39-49, 50-59, and >= 60 years, respectively, which corresponded to an estimated population of 2.75 million. Conclusion: In the 45 to 74 years age bracket, overall and coronary deaths show a decreasing trend, particularly in women, which extends the mean age at death. However, the prevalence of CHD specific to age groups continues to rise, as well.
