Öğe Does Cardiologist Lead Enhanced Heart Failure Education and Follow-up Program Affect Cardiovascular Mortality Rate?: Hit-Point(Lippincott Williams & Wilkins, 2013) Cavusoglu, Yuksel; Zoghi, Mehdi; Eren, Mehmet; Bozcali, Evin; Kozdag, Guliz; Senturk, Tuncay; Alicik, Guray[Abstract Not Available]Öğe Finite strain nonlinear longitudinal vibration of nanorods(Techno-Press, 2018) Eren, Mehmet; Aydogdu, MetinThe nonlinear free vibration of a nanorod subjected to finite strain is investigated. The governing equation of motion in material configuration in terms of displacement is determined. By means of Galerkin method, the Fourier series solutions satisfying some typical boundary conditions are determined. The amplitude-ficquency relationship and interaction between the modes are studied. The effects of nonlocal elasticity are shown for different length of nanotubes and nonlocal parameter. The results show that nonlocal effects lead to additional internal modal interaction for nanorod vibrations.Öğe Nano çubukların doğrusal olmayan titreşim analizi(Trakya Üniversitesi Fen Bilimleri Enstitüsü, 2016) Eren, Mehmet; Aydoğdu, MetinNano çubuğun lineer ve sonlu uzamaya maruz kalan lineer olmayan serbest titreşimi incelendi. Malzeme koordinatlarında hareket denklemleri bulundu. Galerkin yöntemi yardımıyla, bazı tipik sınır koşullarını sağlayan Fourier serileri kullanılarak lineer olmayan denklemlerin çözümlerine ulaşıldı. Genlik-frekans ilişkileri ve modlar arası etkileşim üzerinde çalışıldı. Sonuçlar küçük-ölçek etkisini hesaba katmayan çubuğun titreşim sonuçları ile karşılaştırıldı.Öğe Post-discharge heart failure monitoring program in Turkey: Hit-PoinT(Aves, 2017) Cavusoglu, Yuksel; Zoghi, Mehdi; Eren, Mehmet; Bozcali, Evin; Kozdag, Guliz; Senturk, Tunay; Alicik, GurayObjective: The aim of this study was to assess the efficacy and feasibility of an enhanced heart failure (HF) education with a 6-month telephone follow- up program in post-discharge ambulatory HF patients. Methods: The Hit-Point trial was a multicenter, randomized, controlled trial of enhanced HF education with a 6-month telephone follow-up program (EHFP) vs routine care (RC) in patients with HF and reduced ejection fraction. A total of 248 patients from 10 centers in various geographical areas were randomized: 125 to EHFP and 123 to RC. Education included information on adherence to treatment, symptom recognition, diet and fluid intake, weight monitoring, activity and exercise training. Patients were contacted by telephone after 1, 3, and 6 months. The primary study endpoint was cardiovascular death. Results: Although all-cause mortality didn't differ between the EHFP and RC groups (p=NS), the percentage of cardiovascular deaths in the EHFP group was significantly lower than in the RC group at the 6-month follow up (5.6% vs. 8.9%, p=0.04). The median number of emergency room visits was one and the median number of all cause hospitalizations and heart failure hospitalizations were zero. Twenty-tree percent of the EHFP group and 35% of the RC group had more than a median number of emergency room visits (p=0.05). There was no significant difference regarding the median number of all-cause or heart failure hospitalizations. At baseline, 60% of patients in EHFP and 61% in RC were in NYHA Class III or IV, while at the 6-month follow up only 12% in EHFP and 32% in RC were in NYHA Class III or IV (p=0.001). Conclusion: These results demonstrate the potential clinical benefits of an enhanced HF education and follow up program led by a cardiologist in reducing cardiovascular deaths and number of emergency room visits with an improvement in functional capacity at 6 months in post-discharge ambulatory HF patientsÖğe Post-discharge Heart Failure Monitorization Program in Turkey: Hit-PoinT(Elsevier Science Inc, 2013) Cavusoglu, Yuksel; Zoghi, Mehdi; Eren, Mehmet; Bozcali, Evin; Kozdag, Guliz; Senturk, Tuncay; Alicik, Guray[Abstract Not Available]Öğe Snapshot evaluation of heart failure in Turkey: Baseline characteristics of SELFIE-TR(Turkish Soc Cardiology, 2019) Yilmaz, Mehmet Birhan; Celik, Ahmet; Cavusoglu, Yuksel; Bekar, Lutfu; Onrat, Ersel; Eren, Mehmet; Kutlu, MerihObjective: Heart failure (HF) is an important health issue of the 21st century and the prevalence in Turkey has been reported as 2.9%. A national profile, frequency data, characteristics of different phenotypes, and risk factors have not yet been well established. The Snapshot Evaluation of Heart Failure Patients in Turkey (SELFIE-TR) was an analysis of a representative sample of HF patients from Turkey. Methods: A total of 23 centers with at least 2 cardiologists from the 12 NUTS-1 regions of Turkey were invited to participate in the research. The contributing centers shared the data of a consecutive enrollment of HF patients, as confirmed by an investigator, on a pre-selected day of each week for the month of October or November of 2015. Results: The mean age of the entire cohort was 63.3 +/- 13.3 years (male/female ratio: 751/303, 71.3%/28.7%). There were 712 acute HF patients and 342 chronic HF patients. The total number of HF patients with reduced ejection fraction (HFrEF), heart failure with mid-range ejection fraction, and heart failure with preserved ejection fraction was 801 (75%), 176 (16.7%), and 77 (7.3%), respectively. The patients with chronic HF were younger than those with acute HF (61.1 +/- 13.3 years vs 67.9 +/- 12.1 years; p<0.001). Among the whole cohort, hypertension was observed in 46%, diabetes mellitus was present in 27.5%, chronic obstructive pulmonary disease was present in 12.8%, and previous myocardial infarction was noted in 45.2%. In patients with HFrEF, the use of an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, a beta blocker, or a mineralocorticoid receptor antagonist was noted in 74.7%, 89.7%, and 60.9%, respectively. Conclusion: The SELFIE-TR findings provide important insight, since it is the first study to make a snapshot of HF patients in our country. These data may help to create standardized prevention and treatment strategies.
