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 New Perspective On Fatigue In Hemodialysis Patients With Preserved Ejection Fraction: Diastolic Dysfunction Fatigue And Diastolic Dysfunction(2022) Akbay, Ertan; Akinci, Sinan; Coner, Ali; Adar, Adem; Genctoy, Gultekin; Demir, Ali Riza; https://orcid.org/0000-0002-9146-0621; https://orcid.org/0000-0001-5250-5404; AAD-5479-2021; AAD-5564-2021The relationship between diastolic dysfunction and fatigue in hemodialysis patients with preserved ejection fraction is unknown. In this context, the objective of this study is to assess fatigue using the relevant scales and to demonstrate its relationship with diastolic dysfunction. The patients who underwent hemodialysis were evaluated prospectively. Patients' fatigue was assessed using the Visual Analogue Scale to Evaluate Fatigue Severity (VAS-F). The echocardiographic works were performed as recommended in the American Society of Echocardiography guidelines. A total of 94 patients [mean age 64.7 +/- 13.5 years, 54 males (57.4%)] were included in the study. The median VAS-F score of these patients was 68.5 (33.25-91.25), and they were divided into two groups according to this value. Peak myocardial velocities during early diastole (e ') and tricuspid annular plane systolic excursion (TAPSE) values were found to be significantly lower in the group with high VAS-F scores, whereas the early diastolic flow velocities (E)/e ' ratio and pulmonary artery peak systolic pressures (PAP) were found to be significantly higher (p < 0.05, for all). E/e ' ratio (r 0.311, p 0.002) and PAP (r 0.281, p 0.006) values were found to be positively correlated with the VAS-F score, as opposed to the TAPSE (r - 0.257, p 0.012) and e ' (r - 0.303, p 0.003) values, which were found to be negatively correlated with the VAS-F score. High fatigue scores in hemodialysis patients may be associated with diastolic dysfunction. In addition, in our study, we determined the correlation of VAS-F score with E/e ' ratio, PAP and TAPSE.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 In-Hospital Cardiac Complications in Legionnaires' disease: A Single Center Experience of 32 Patients(2021) Akinci, Sinan; Coner, Ali; 0000-0001-5250-5404; 0000-0002-5711-8873; AAD-5564-2021; ABD-7321-2021Introduction: Legionella species frequently causes Legionnaires' disease (LD), a community-acquired pneumonia (CAP). Although data on cardiac events during the course of CAP can be found in the literature, there has been little research on the same issue in LD patients specifically. This study aimed to investigate cardiac complications in the course of LD. Materials and Methods: A total of 32 patients hospitalized with CAP and who received a definitive diagnosis of Legionella infection were identified from the hospital database and included in the study population. The patients' electronic and written records were evaluated for possible cardiac complications. Results: Mean age was 65 +/- 13.5 years and 50% of the subjects were males. Seven patients died during hospitalization. Cardiovascular events were detected in 11 patients. New-onset atrial fibrillation was the most frequent event and was detected in 8 patients (25%), while two patients experienced a myocardial infarction, and one patient was diagnosed with myocarditis. The cardiovascular events were significantly related to the pneumonia severity index (PSI) score and need for intensive care unit. Conclusion: Although LD rarely involves the heart, it can often cause cardiac complications, and the frequency increases in parallel with the severity of the disease. This study indicates that patients with LD should be carefully followed for possible cardiac complications.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.
