    (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-5564-2021
    The 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.

    (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; 36189879
    Background 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.

    Pheochromocytoma: An overlooked reversible cause of heart failure with reduced ejection fraction
    (2021) Coner, Ali; Ozyildiz, Ali Gokhan; 0000-0002-5711-8873; 34523598; ABD-7321-2021
    Pheochromocytoma is a rare, benign tumor of adrenal medulla, and its clinical symptoms are related to catecholamine production. Clinical presentation may vary in a broad spectrum. Dilated or hypertrophied cardiomyopathies are the possible clinical outcomes of pheochromocytoma. Pheochromocytoma should be kept in mind in the differential diagnosis where resistant hypertension, palpitations, headache, and sweating accompany cardiomyopathy. Excessive adrenergic stimulation causing catecholamine discharge can trigger hypertension crisis, pulmonary edema, and myocardial necrosis. Here in this report, we aimed to present the case of a patient with pheochromocytoma related cardiomyopathy who was totally recovered after surgical excision of the tumor.

    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-5564-2021
    Objective: 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.

    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; 32120362
    Objective: 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.
