Item A New Chest Radiography Clue to Predict Saphenous Vein Graft Failure(2022) Akbay, Ertan; Coner, Ali; Akinci, Sinan; Adar, Adem; Demir, Ali Riza; Uygur, Begum; Saba, Tonguc; Budak, Ali Baran; Muderrisoglu, Ibrahim HaldunObjective: Saphenous vein graft failure (VGF) is a measure of the short-and long-term success of coronary artery bypass graft surgery (CABG). Aortic arch calcification (AAC) is a long-term finding of atherosclerosis in large vessels. The aim of this study was to evaluate the relationship between AAC and VGF.Materials and Methods: Patients who underwent CABG surgery and subsequent coronary angiography in a single hospital between January 2010 and January 2021 were included in the study. The presence and stage of AAC was evaluated using preoperative chest X-rays. VGF was defined as >= 75% stenosis and/or total occlusion in the saphenous vein graft. In addition, the effect of AAC on VGF was evaluated based on the time elapsed since the CABG procedure. Results: Of the 594 patients who underwent CABG during the study period, 91 patients (mean age 63.6 +/- 10.0; 71 [78.0%] male) were included in the study. VGF was observed in 49 (53.8%) patients. AAC was found to be an independent predictor of VGF (odds ratio [OR]: 2.788, 95% confidence interval [CI]: 1.068-7.278). The results indicated no association between AAC and VGF in patients whose coronaries were screened within 1 year (OR: 1.143, 95% CI: 0.279-4.683), while there was a strong association between AAC and VGF in patients who were screened 1 year after the surgery (OR: 5.355, 95% CI: 1.618-17.720).Conclusion: AAC evaluation may be a valuable diagnostic method to predict VGF after CABG, and particularly late VGF.Item The Effect of Coronary Angiography and Femoral Access on Femoral Artery Distensibility and Elasticity(2021) Gunesli, Aylin; Acibuca, Aynur; 33791115Aim of the study: The aim of this study was to evaluate the long-term effects of access to the femoral artery for the purposes of coronary angiography through the measurement of femoral artery distensibility and elasticity on the accessed and non-accessed sides. Material and methods: This cross- sectional study included patients who underwent femoral angiography at least 1 year previously. Those whose femoral artery was accessed once formed Group 1 (n = 59), those who were accessed twice formed Group 2 (n = 57), those accessed 3 times formed Group 3 (n = 55), and those with more than 3 accesses, Group 4 (n = 60). The groups were compared in respect of femoral artery elasticity and distensibility in the accessed and non-accessed sides. Results: No statistically significant difference was determined in respect of femoral distensibility and elasticity in Group 1 (9.40 +/- 0.84 vs 9.48 +/- 0.75, p = 0.107 and 0.23 +/- 0.03 vs 0.23 +/- 0.03, p = 0.433, respectively). However, a significant difference was observed between the two sides in terms of distensibility and elasticity in Group 2 (9.02 +/- 0.81 vs 9.23 +/- 0.75, and 0.21 +/- 0.02 vs 0.22 +/- 0.02), in Group 3 (8.49 +/- 0.77 vs 9.18 +/- 0.9 and 0.19 +/- 0.02 vs 0.21 +/- 0.02), and in Group 4 (8.14 +/- 0.74 vs 9.03 +/- 0.81 and 0.16 +/- 0.01 vs 0.2 +/- 0.02, p <0.001, for all comparisons). Conclusion: While a single access in the femoral artery for coronary angiography does not affect femoral artery elasticity and distensibility, multiple accesses may have adverse effects.Item Prevalence and clinical profile of patients with myocardial infarction with non-obstructive coronary arteries in Turkey (MINOCA-TR): A national multi-center, observational study(2020) Coner, Ali; 32120362Objective: Myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA) is a relatively new term that is characterized by clinical evidence of MI with normal or near-normal coronary arteries on coronary angiography (QCA). To date, there have been no population-based studies on the prevalence of MINOCA in Turkey. The aim of this nationwide study was to document the prevalence and demographics of MINOCA in a Turkish population. Methods: MINOCA-TR is national, multi-center, prospective, all-comer study that was conducted in 32 hospitals. All consecutive patients who were >= 18 years old, diagnosed with MI according to the Third Universal Definition of Myocardial Infarction, and had undergone DCA were included in the study. Patients with stable coronary artery disease, unstable angina pectoris, a history of revascularization, and type 4/5 MI were excluded. Results: A total of 1793 patients who were diagnosed with MI and had undergone QCA were screened between March 2018 and October 2018, of whom 1626 (mean age: 61.5 +/- 12.5 years, 70.7% male) were enrolled from 32 centers. The prevalence of MINOCA was 6.7% (n=109) in the overall study population. Compared with non-MINOCA patients, those with MINOCA were younger, had a higher prevalence of the female gender, and had a history of flu. The percentages of current smokers, ST-segment elevated myocardial infarction patients, and those with a history of hypertension, diabetes mellitus, and hyperlipidemia were significantly lower in MINOCA patients (p<0.05, for all). Also, the median left ventricular ejection fraction as seen on echocardiography and the ratio of Killip Class I status at presentation was significantly higher in MINOCA patients than in non-MINOCA patients (p<0.001). Patients with MINOCA received a preload dose of P2Y12 antagonist before QCA less often than non-MINOCA patients (p<0.001). Conclusion: The prevalence of MINOCA in Turkey is 6.7% in patients who were admitted with MI. Also, as compared to non-MINOCA patients, the MINOCA patients were exposed to fewer traditional risk factors of coronary artery disease.Item Relationship of periodontitis and edentulism to angiographically diagnosed coronary artery disease: A cross-sectional study(2020) Cetin, Mehtap Bilgin; Onder, Canan; Orhan, Kaan; Kumbasar, Deniz; Serdar, Muhittin Abdulkadir; Unsal, Elif; 32648271Objective The objective of the study is to examine the connection between oral status and the extent of coronary artery disease (CAD), which is diagnosed by angiography. Background Periodontitis and tooth loss have been linked to atherosclerosis and CAD in previous studies. However, no distinct connection was revealed due to the diversity of the results and the variety of diagnostic methods. To provide a more consistent data pool and stronger evidence, there is a need for studies with standard measurements and diagnostic criteria. Methods 309 patients, who consulted to Ankara University, Faculty of Medicine, Department of Cardiology and had coronary angiography, were enrolled to this study. Individuals were grouped based on their coronary angiography results, as CAD (+) (n = 233) and CAD (-) (n = 76). Studied parameters included cardiovascular risk factors, plaque index (PI), remaining teeth count, bleeding on probing (BOP), and probing pocket depth (PPD). Periapical radiographs were taken from teeth with >= 4 mm PPD. Oral status was categorized as periodontally healthy subjects/patients with gingivitis (Group 1), patients with periodontitis (Group 2), and edentulous subjects (Group 3). Results PI (P < 0.001), PPD (P = 0.001), BOP (P = 0.004), the number of patients with less than 10 teeth (P = 0.014), and edentulism (P = 0.009) were significantly higher in CAD (+) patients, who were mostly older (P < 0.001) and male (P < 0.001). Multivariate logistic regression analysis revealed that Group 2 (odds ratio = 2.48, 95% confidence interval = 1.24-4.95,P = 0.010) and Group 3 (odds ratio = 2.01, 95% confidence interval = 1.14-5.17,P = 0.040) were highly associated with CAD. Two and three stenosed vessels were significantly higher in Groups 2 and 3 compared to Group 1 (P = 0.003). Conclusions It was found that both edentulism and periodontitis were related to CAD.
