Objective: The goal of this study was to define clinical practice patterns for assessing stroke and bleeding risks and thromboprophylaxis in nonvalvular atrial fibrillation (NVAF) and to evaluate treatment outcomes and patient quality of life. Methods: A clinical surveillance study was conducted in 10 tertiary healthcare centers across Turkey. Therapeutic approaches and persistence with initial treatment were recorded at baseline, the 6th month, and the 12th month in NVAF patients. Results: Of 210 patients (57.1% male; mean age: 64.86 +/- 12.87 years), follow-up data were collected for 146 patients through phone interviews at the 6th month and 140 patients at the 12th month. At baseline, most patients had high CHADS(2) score (>= 2: 48.3%) and CHA(2)DS(2)-VASc (>= 2: 78.7%) risk scores but a low HAS-BLED (0-2: 83.1%) score. Approximately two-thirds of the patients surveyed were using oral anticoagulants as an antithrombotic and one-third were using antiplatelet agents. The rate of persistence with initial treatment was approximately 86%. Bleeding was reported by 22.6% and 25.0% of patients at the 6th and 12th month, respectively. The proportion of patients with an INR of 2.0-3.0 was 41.8% at baseline, 65.7% at the 6th month, and 65.9% at the 12th month. The time in therapeutic range was 61.0% during 1 year of follow-up. The median EuroQol 5-dimensional health questionnaire (EQ-5D) score of the patients at baseline and the 12th month was 0.827 and 0.778, respectively (p<0.001). The results indicated that patient quality of life declined over time. Conclusion: In atrial fibrillation, despite a high rate of persistence with initial treatment, the outcomes of stroke prevention and patient quality of life are not at the desired level. National health policies should be developed and implemented to better integrate international guidelines for the management of NVAF into clinical practice.

(2017) Akinci, Sinan; Balcioglu, Akif Serhat; Tacoy, Gulten; Tavil, Yusuf; Guslbahar, Ozlem; Ozdemir, Murat; https://orcid.org/0000-0001-5250-5404; 28597800; AAD-5564-2021
Objective Heart fatty acid binding protein (HFABP) is a low-molecular-weight free protein that is abundant in the intracytoplasmic space of myocytes. Due to its unique features, serum HFABP levels may increase in myocardial ischaemia. The aim of this study was to evaluate the effect of myocardial ischaemia induced by dobutamine stress echocardiography (DSE) on serum HFABP levels. Methods and results A total of 30 consecutive patients with suspected myocardial ischaemia underwent DSE examination. HFABP levels were measured immediately before and 1 hour after DSE. HFABP rose significantly in individuals in the DSE positive group (1.66 +/- 1.18 ng/ml vs 2.65 +/- 1.34 ng/ml, P = 0.004), but remained unchanged in the DSE negative group (1.61 +/- 0.77 ng/ml vs 1.85 +/- 0.76 ng/ml, P = 0.066). Conclusion Serum HFABP levels increased significantly at 1 hour in the presence of ischaemia induced by DSE in patients with stable clinical coronary syndromes. No such increase was evident in the absence of ischaemia.

Natriuretic peptides have long been introduced into clinical practice. These biomarkers have certainly been shown to provide useful information in the diagnosis, prognosis and risk stratification in heart failure and also may have a role in the guidance of heart failure therapy. Although, there are some limitations in using of these markers such as lack of specificity, aging, renal dysfunction or obesity, among the huge number of candidates for heart failure biomarkers, only natriuretic peptides are currently widely used in daily clinical practice in heart failure. Recent heart failure guidelines recognize natriuretic peptides as an essential tool in the new diagnostic and therapeutic algorithms. Furthermore, natriuretic peptides are not only used in the diagnosis or prognosis of heart failure, but also these biomarkers are referred to have some potential role in primary prevention, cardio-oncology, advanced heart failure, assessment of response to cardiac resynchronization therapy, pulmonary arterial hypertension, acute coronary syndromes, atrial fibrillation and valvular heart disease. In this article, natriuretic peptides have been reviewed for their updated information and new recommendations in heart failure and also potential role of these biomarkers in the management of various clinical conditions have been addressed in the form of expert opinion based on the available data in the literature.
