Abstract
INTRODUCTION The presence of concomitant erectile dysfunction (ED) with heart failure (HF) is not surprising, because endothelial dysfunction is pathophysiologic signature of both ED and HF. ED significantly and adversely affects quality of life in patients with HF. It was demonstrated that ivabradine treatment can improve endothelial function and ED in experimental models. In this study, we aimed to determine the effect of ivabradine treatment on ED in patients with HF via International Index of Erectile Function (IIEF-5) questionaire. MATERIAL AND METHODS Consequently, 29 patients, between 18 and 70 years of age, male with chronic HF known for at least 1 year, New York Heart Association functional class I-II, left ventricule ejection fraction less than 40%, in sinus rhythm with a resting HR of at least 70 beats per minute (b.p.m.), who were intended to be treated with ivabradine according to the decision of their physicians were evaluated to determine ED. We used the Turkish version of the IIEF-5 questionnaire to evaluate ED on the last 6-month period. Twenty-four of 29 patients who scored ≤21 were considered to have ED and included to the study. IIEF-5 scores for each question and domains were calculated for all responders at baseline and at 6-month follow-up visit in order to determine any effect of ivabradine treatment on ED in patients with HF. RESULTS According to the data of survey, Cronbach's alpha coeffient for all of the patients who were included into the study were 0.84 and detected highly reliable. IEFF-5 questionnaire scores increased significantly (p = .003) after the ivabradine treatment, on the contrary, significant decrease in HR was revealed as expected. HR is decreased steadily after ivabradine treatment and mean decrease in HR was 11.5 ± 9.4 in this study population. Likewise, negative correlation was demonstrated between decrease in HR (p < .001) and increase in IEFF-5 scores (p = .003). CONCLUSION Although lack of patients with HF have been evaluated in this study population, initial results seem promising that ivabradine has favorable effects on ED. These findings were postulated to be dependent exclusively on HR reduction. As a sequel, cardiologist should avoid neglecting ED to improve medical compliance as well as quality of life in patients with heart failure. This pilot study provide some data for further randomized controlled studies.

Abstract
OBJECTIVE A wide gap exists between dyslipidemia guidelines and their implementation in the real world, which is primarily attributed to physician and patient compliance. The aim of this study is to determine physician and patient adherence to dyslipidemia guidelines and various influential factors. METHODS The Evaluation of Perceptions, Knowledge, and Compliance with the Guidelines in Real Life Practice: A Survey on the Under-treatment of Hypercholesterolemia (EPHESUS) trial (ClinicalTrials.gov number NCT02608645) will be an observational, multicenter, non-interventional study. The study targets enrollment of 2000 patients from 50 locations across Turkey. All of the data will be collected in a single visit and current clinical practice will be evaluated. A cross-sectional survey of public perception and knowledge of cholesterol treatment among Turkish adults will be performed. All consecutive patients admitted to cardiology clinics who are in the secondary prevention group (coronary heart disease, peripheral artery disease, atherosclerotic cerebrovascular disease) and who are in the high-risk primary prevention group (type 2 diabetes mellitus with no prior known coronary heart disease; patients who had markedly elevated single risk factors, in particular, cholesterol >8 mmol/L [>310 mg/dL], blood pressure ≥180/110 mmHg, a calculated Systematic Coronary Risk Evaluation [SCORE] ≥5%, or <10% 10-year risk of fatal cardiovascular disease) will be included. Demographic, lifestyle, medical, and therapeutic data will be collected with a survey designed for the study. CONCLUSION The EPHESUS registry will be the largest study conducted in Turkey evaluating the adherence to dyslipidemia guidelines both in secondary and high-risk primary prevention patients.

Abstract
OBJECTIVE Sudden cardiac death in athletes is one of the most tragic health events seen both in our country and all over the world. In some of those athletes, there is no obvious structural abnormality. Dynamic changes in intracardiac hemodynamics during exercise may be a cause for sudden death in these athletes, the impact of exercise on intracardiac gradient and cardiac hemodynamic parameters in athletes was compared with healthy controls. METHODS A total of 21 professional male athletes and 21 healthy male controls were included in the study. Transthoracic echocardiography was performed in all participants both at rest and maximal exercise level to assess the intraventricular gradient (IVG) and cardiac systolic and diastolic functions. Abnormal IVG was defined as gradient of >30 mm Hg at peak exercise level. RESULTS Both groups reached the level of predicted maximum exercise. There was no exercise limiting symptom among participants during exercise test. The athletes revealed a higher maximum peak systolic IVG at baseline and after exercise in comparison with the control group. None of the participants showed an abnormal IVG level. CONCLUSION Our results showed that there was no dynamic intraventricular obstruction with aerobic exercise in subjects with a structurally normal heart.

Abstract
OBJECTIVE Atrial fibrillation is the most common arrhythmia and is associated with a five- fold increased risk of thromboembolic events. Vitamin K antagonists (VKAs) have been the mainstay of oral anticoagulant prophylaxis and the data on stroke prevention strategies are limited to VKA era. The purpose of this study is to evaluate the use of VKA, non-Vitamin K antagonist oral anticoagulants (NOAC), and antiplatelet agents in patients with non-valvular atrial fibrillation (NVAF). METHODS The ReAl-life Multicenter Survey Evaluating Stroke prevention strategies in Turkey (RAMSES) is an observational, multicenter, prospective study of patients with NVAF. The study targeted enrollment of 7835 patients from 68 sites in Turkey. All the data will be collected at one point in time and current clinical practice will be evaluated. (ClinicalTrials.gov number NCT02344901). RESULTS Baseline characteristics of patients, antithrombotic therapies, transition to NOACs and rate/rhythm control strategies will be evaluated. CONCLUSION The RAMSES registry will be the largest study in Turkish NVAF patients. The study will provide insights into real-world problems and anticoagulant treatment in patients with NVAF.

Abstract
Bodybuilder-type workouts may affect heart rate variability (HRV), which has considerable potential to assess the role of autonomic nervous system (ANS). A scientifically designed approach is necessary for bodybuilders to achieve better results while protecting their health. In this study, we aimed to investigate HRV parameters in bodybuilders compared to healthy control subjects and effects of creatine supplementation. A total of 48 male participants (16 controls, 16 supplement (-), 16 supplement (+)) were evaluated in our study. Bodybuilders who were taking creatine supplementation were enrolled in supplement (+) group. HRV parameters were measured from 24-hour Holter recordings of all participants. When mean heart rates were compared with control group (71.5 ± 12.6 beats/min), statistically significant difference was revealed in supplement (-) group (61.8 ± 6.8 beats/min; P = 0.022) unlike supplement (+) group (69.63 ± 14.1 beats/min; P = 0.650). HRV analyses revealed significant parasympathetic shift in supplement (-) group. No significant difference was demonstrated on HRV parameters, except high frequency (P = 0.029) in supplement (+) group. Conclusively, elevated parasympathetic modulation, which is favorable cardiovascular outcome of exercise, was demonstrated in bodybuilders. However, our study also revealed that creatine supplementation attenuates this favorable effect in ANS by limiting elevation of parasympathetic modulation. Although the sympathetic slight shift is attributed to creatine supplementation, it cannot be discriminated from the effects of over training.

Abstract
Although the presence of brucella endocarditis is encountered rarely, it is the most fetal complication of brucellosis, which is shown to affect the aortic valve primarily and the mitral valve secondarily. Involvement of the tricuspid valve is extremely rare. A 62-year-old female was admitted with complaints of fever, fatigue, difficulty in breathing, and swellings in her legs. A transthoracic echocardiogram was performed since acute right heart failure was considered due to her symptoms. The echocardiogram showed enlarged right heart chambers, serious tricuspid valve insufficiency, and a mass on the tricuspid valve compatible with a vegetation moving in and out of the right ventricle. Although no growths were observed in the blood culture, antibody titration for brucellosis was found to be 1/640 (+) in the serological examination. The patient was diagnosed with brucella endocarditis and placed on doxycycline, rifampicin, and ceftriaxone treatment for eight weeks. At the end of the eight-week treatment, the symptoms of right heart failure receded and the patient recovered from the endocarditis. Tricuspid valve brucella endocarditis should be considered in patients suffering from acute right heart failure accompanied by systemic infection findings since brucellosis is presently endemic in Turkey.
