Item Evaluation of the relationship between para-aortic adipose tissue and ascending aortic diameter using a new method(2022) Adar, Adem; Onalan, Orhan; Cakan, Fahri; Keles, Hakan; Akbay, Ertan; Akinci, Sinan; Coner, Ali; Haberal, Cevahir; Muderrisoglu, Haldun; https://orcid.org/0000-0002-9146-0621; https://orcid.org/0000-0001-5250-5404; https://orcid.org/0000-0002-5711-8873; https://orcid.org/0000-0002-6496-5050; 36189879Background Para-aortic adipose tissue (PAT) is the local adipose tissue that externally surrounds the aorta. It contributes significantly to aortic atherosclerosis and enlargement. Studies conducted with computed tomography and magnetic resonance have shown that individuals with aortic aneurysm had more PAT than healthy individuals. In this study, we measured PAT using transthoracic echocardiography (TTE). The aim of this study is to investigate the possible relationship of TTE measured PAT with ascending aortic width. Methods PAT was defined as the hypoechoic space in front of ascending aortic 2 cm above the sinotubular junction at the end of the systole. Patients were divided into 2 groups according to the presence of dilatation in the ascending aorta using Roman's classification (aortic size index, ASI). ASI of less than 21 was considered no aortic dilation and an ASI of 21 mm/m2 or greater was considered to have aortic dilation. Results A total of 321 unselected patients were divided into the ascending aortic dilatation (AAD) group (n = 96) and the normal ascending aorta diameter group (n = 225 patients). PAT was significantly higher in the AAD group compared with the non-ADD group (0.9 (0.48) vs. 0.7 (0.91) mm, p < 0.0001). Univariate and multivariate logistic regression analysis revealed that PAT (OR: 3.005, 95%CI (1.445-6.251)) were significantly associated with AAD. Conclusions This is the first study which evaluated PAT measured by TTE. We found a significant association between PAT measured by TTE and ascending aorta width.Item Admission Tpe interval predicts reperfusion success in STEMI patients treated with fibrinolytic agents(2020) Coner, Ali; Akinci, Sinan; Akkucuk, Mehmet Husamettin; Altin, Cihan; Muderrisoglu, Haldun; 0000-0002-9635-6313; 0000-0003-4569-1143; 0000-0001-5250-5404; 31974326; AAG-8233-2020; AAJ-2828-2021; AAD-5564-2021Objective: Myocardial infarction is a leading cause of morbidity and mortality. Fibrinolytic administration is still a life-saving choice in ST-segment elevated myocardial infarction (STEMI), but the rate of successful reperfusion can be inconsistent. Failed reperfusion adds additional clinical risks to rescue percutaneous coronary intervention for STEMI patients. The interval between the peak of the T wave and the end of the T wave (Tpe) and the ratio of Tpe and a corrected measurement of the time from the start of the Q wave to the end of the T wave (Tpe/QTc ratio) are relatively new electrocardiogram (ECG) indices and have not yet been tested in STEMI patients treated with fibrinolytic agents. Methods: A total of 177 STEMI patients (mean age: 60.5 +/- 11.1 years; 138 men and 39 women) were enrolled in this retrospective study to evaluate ECG parameters. The Tpe interval and the Tpe/QTc ratio at baseline and at the 90th minute following the administration of fibrinolytic therapy were analyzed. The clinical and ECG findings of successful and failed reperfusion groups were compared. Results: Successful reperfusion was achieved in 119 patients (67.2%). The average Tpe interval on the admission ECG was shorter (91.7 vs. 100.9 milliseconds [ms]) (p<0.001) and shortened more in the successful reperfusion group (9.3 vs. 4.5 ms) (p<0.001). A cut-off value of 89.0 ms for the Tpe interval on the admission ECG was found to be related to reperfusion success with a sensitivity of 90.9%. Conclusion: The Tpe interval was a predictor for reperfusion success in STEMI patients treated with fibrinolytic agents.Item Salusin beta, atherosclerosis, and coronary slow flow(2020) Akinci, Sinan; Coner, Ali; 0000-0001-5250-5404; 32011318; AAD-5564-2021Item Cardiac autonomic nervous dysfunction detected by both heart rate variability and heart rate turbulence in prediabetic patients with isolated impaired fasting glucose(2016) Balcioglu, Akif Serhat; Akinci, Sinan; Cicek, Davran; Coner, Ali; Bal, Ugur Abbas; Muderrisoglu, Ibrahim Haldun; 0000-0002-9446-2518; 0000-0002-5711-8873; 0000-0001-5250-5404; 27025199; AAK-4322-2021; ABD-7321-2021; AAD-5564-2021; AAC-8036-2020Objective: Cardiac autonomic nervous dysfunction (CAND), a severe complication of diabetes, has also been shown to affect prediabetic patients. The role of isolated impaired fasting plasma glucose (IFG), a subtype of prediabetes, is not clear in the pathogenesis of CAND. The aim of this study was to examine the relationship between isolated IFG and cardiac autonomic function using heart rate variability (HRV) and heart rate turbulence (HRT) indices derived from 24-h Holter-electrocardiogram recordings. Methods: This observational, prospective, cross-sectional study examined 400 consecutive subjects divided into three groups according to oral glucose tolerance test results: the control group [Group I, fasting plasma glucose (FPG) <100 mg/dL and normal glucose tolerance, n=193], the isolated IFG group (Group II, FPG >= 100 and <126 mg/dL, n=134), and the isolated impaired glucose tolerance (IGT), both IFG and IGT, or newly diagnosed diabetes' group (Group III, n=73). Patients with non-sinus rhythm, known diabetes mellitus, coronary artery disease, heart failure, severe valvular disease, or receiving medical therapy that may affect HRV and HRT indices were excluded. Time domain HRV parameters, turbulence onset (TO), turbulence slope (TS), and HRT category were examined. Chi-square, one-way analysis of variance, Kruskal-Wallis H, and Mann-Whitney U tests were used to compare variables where appropriate. The correlation between Holter data and FPG levels was analyzed using the Spearman's test. Multiple linear regression analysis was performed to identify independent predictors of the HRV and HRT parameters. Results: Median (interquartile range 25-75) FPG levels in Groups I, II, and III were 89 (83/93) mg/dL, 109 (104/116) mg/dL, and 174 (150.5/197) mg/dL, respectively. There were significant differences in HRV and HRT parameters between and among all groups. While HRV parameters and TS decreased from Group I to Group III, TO and HRT category gradually increased. Additionally, FPG level was significantly correlated with SDNN, r=-0.220; SDNN index, r=-0.192; SDANN, r=-0.207; RMSSD, r=-0.228; pNN50, r=-0.226; TO, r=0.354; and TS, r=-0.331 (all p<0.001). Conclusion: CAND, as detected by both HRV and HRT, appear to be present in the isolated IFG subtype of prediabetes.Item Renal artery stenting of chronic kidney disease patient with resistant hypertension(2016) Coner, Ali; Cicek, Davran; Akinci, Sinan; Muderrisoglu, Haldun; 0000-0002-5711-8873; 0000-0002-9635-6313; 0000-0001-5250-5404; 27872437; ABD-7321-2021; AAC-8036-2020; AAG-8233-2020; AAD-5564-2021Item Acquired pseudoaneurysm of the sinus of Valsalva(2017) Coner, Ali; Akinci, Sinan; Cicek, Davran; Saba, Tonguc; Muderrisoglu, Haldun; 0000-0001-5250-5404; 0000-0002-9635-6313; 0000-0002-5711-8873; 28902654; AAD-5564-2021; AAG-8233-2020; ABD-7321-2021; AAC-8036-2020Item Successful treatment of massive pulmonary embolism with reteplase(2018) Coner, Ali; Cicek, Davran; Balcioglu, Serhat; Akinci, Sinan; Müderrisoglu, Haldun; 0000-0002-9635-6313; 0000-0001-5250-5404; 0000-0002-5711-8873; 29512616; AAC-8036-2020; AAG-8233-2020; AAD-5564-2021; ABD-7321-2021Unexpected and unexplained out-of-hospital cardiac arrests have a poor prognosis. Difficulties encountered during the differential diagnosis phase may delay the administration of specific treatment for treatable and reversible causes of cardiac arrest. Massive pulmonary embolism is a reversible cause of cardiac arrest, but without proper management it has a high mortality rate. Presently described is the case of a 53-year-old female patient with a massive pulmonary embolism.Item Mid-term clinical outcomes of new generation drug-eluting stents for treatment of diffuse coronary artery disease(2018) Coner, Ali; Cicek, Davran; Akinci, Sinan; Balcioglu, Serhat; Altin, Cihan; Muderrisoglu, Haldun; 30516523Objective: Diffuse coronary artery disease (CAD) is a challenging issue in clinical cardiology practice. There are limited data about percutaneous revascularization in these patients. Methods: This study was an observational clinical evaluation. The records of patients with diffuse CAD revascularized with new-generation drug-eluting stents (DES) were researched retrospectively. Patients treated with multiple, overlapping new-generation DES (at least 60mm in length per vessel) were included. The incidence of major adverse cardiac events (MACE), defined as cardiac death, stent thrombosis, non-fatal myocardial infarction, and target lesion revascularization (TLR), at the end of the first year following the index procedure was recorded. Results: A total of 71 patients (with 75 coronary vessels) treated with new-generation DES for diffuse CAD were enrolled in the study. Zotarolimus-eluting stents were used in 48 vessels and biolimus A9-eluting stents were used in 27 vessels. The median total stent length per vessel was 75.0 mm (60.0-106.0) and the median number of stents implanted was 3 (2-4) for each vessel. The cumulative incidence of MACE at the end of the first year was 11.2% (8 patients). The presence of diabetes mellitus (DM) and ST-segment elevated myocardial infarction (STEMI) were defined as independent clinical risk factors related to MACE development. Conclusion: Coronary artery revascularization with new-generation drug-eluting stents can be a good choice in the treatment of selected patients with diffuse CAD. DM and STEMI were found to be related to poorer clinical outcomes with this treatment option in our study.
