Article Exploring Hypertension Awareness in Physicians: A Cross-Sectional Study From Turkey(Termedia Publishing House Ltd, 2025) Taskin, Ugur; Fici, Francesco; Altin, Cihan; Dogdus, Mustafa; Mammadov, Ganbar; Topaloglu, Caner; Tengiz, IstemihanIntroduction: Hypertension is a significant public health concern and a contributor to cardiovascular conditions. Although physicians are essential in preventing and managing hypertension, limited research has been conducted on their own awareness of the condition. Aim: We aimed to examine the prevalence and awareness of hypertension among doctors in Turkey and identify relevant demographic and behavioral risk factors. Material and methods: A cross-sectional study was carried out with 178 physicians aged 25 to 64, randomly chosen from 35 healthcare institutions in 24 cities across Turkey. Data collection involved a structured questionnaire that examined hypertension awareness, sociodemographic details, and cardiovascular risk factors, complemented by standardized blood pressure assessments and body measurements. Hypertension was identified based on a systolic blood pressure of >= 140 mm Hg and/or a diastolic pressure of >= 90 mm Hg, self-reported diagnosis, or the use of antihypertensive drugs. Results: The overall prevalence of hypertension was 15.7%, with a significantly higher rate among males (20.2%) than females (7.8%) (p = 0.03). Age was a strong predictor, as individuals over 40 years had a markedly higher hypertension prevalence (27.9%) compared to those under 40 (4.3%) (p < 0.001). Body mass index (BMI), smoking, and physical inactivity were also significantly associated with hypertension. Among hypertensive doctors, awareness was 78.5%, though it did not show significant differences based on gender, BMI, or comorbidities. Conclusions: Despite relatively high awareness levels, hypertension remains prevalent among medical professionals, particularly in older and male doctors. Targeted strategies, such as routine screenings and lifestyle intervention programs, are essential to improve hypertension prevention and management in this population.Article Effects of Different Forms of Statins on Lipid Profile in Hyperlipidemic Patients(Asian Network Scientific Information-Ansinet, 2023) Arıcan Tarım, Bahar; Topaloğlu, Caner; Elif, Ari; Tengiz, İstemihan; Nicolas, Robles Roberto; Gökhan, Faikoğlu; Saygısever-Faikoğlu, KübraBackground and Objective: Statins are the cornerstone of dyslipidemia treatment. This class of drugs decreases all lipids, particularly LDL-C and non-HDL-C and consequently the risk of cardiovascular events. Different trials have, frequently, compared the effect of two statins, while very few studies have directly compared three statins in the same study. The aim of this trial was to evaluate the lipid-slowering effect of atorvastatin, rosuvastatin and pitavastatin, at moderate doses, in a head-to-head comparison, in patients with dyslipidemia. Materials and Methods: The current study was a prospective, randomized, open-label, parallel-group study with blinded endpoints (PROBE design) involving 221 patients. After clinical examination, patients were randomized to atorvastatin (20 mg dLG1), rosuvastatin (10 mg dLG1) or pitavastatin (2 mg dLG1) and followed for 6 months. The primary endpoint of this trial was the change of lipids from baseline. Secondary endpoints included: The rate of subjects with LDL-C reduction >30% and 50% and the lowering effect on non-HDL-C. Results: At the end of this study atorvastatin, rosuvastatin and pitavastatin significantly (p<0.001) decreased plasma levels of lipids, compared with baseline values: (TC -30.1, - 39.1 and -26.8%), LDL-C (-39.1, -40.7 and -38.2%), TG (- 20.5, -17.6 and -13.4%), non-HDL-C (-36.4, -37.1 and -33.4%). No statistically significant difference was obtained between statins at the end of treatment. Differently from atorvastatin and rosuvastatin, pitavastatin increased the level of HDL (1.9%). Conclusion: The lipid-lowering efficacy of atorvastatin, rosuvastatin and pitavastatin is not statistically different, except for the HDL-C.Article Citation - Scopus: 1Ablation of Atrioventricular Nodal Reentrant Tachycardia With Focal Cryoablation, Compared With Radiofrequency Ablation: Single-Center Experience(2024) Topaloğlu, C.; Fici, F.; Borne, P.V.; Taşkin, U.; Dogdus, M.; Saygi, S.; Tengiz, I.BACKGROUND: The ablation of atrioventricular nodal reentrant tachycardia (AVNRT) with cryoablation is an alternative to radiofrequency (RF) ablation in patients due to the low risk of total atrioventricular block. An increase in early-late recurrences after cryoablation is reported as an important disadvantage. OBJECTIVES: In this study, we aimed to compare the acute procedural success and the long-term recurrence rates of patients, with AVNRT who underwent methods. METHODS: 73 patients with AVNRT were included in the study: 32 with cryoablation and 41 with RF ablation. There was no statistically significant difference between acute procedural success in methods. The ablation procedure was performed by an operator experienced in arrhythmology. The choice of RF or cryoablation was made in the electrophysiology laboratory based on the material already available during the procedure. After the procedure, the patients were evaluated every 3 months for 2 years in polyclinic control. The significance level adopted in the statistical analysis was 5%. RESULTS: The 2 groups of patients were homogeneous.Article Citation - WoS: 1Ablation of Atrioventricular Nodal Reentrant Tachycardia With Focal Cryoablation, Compared With Radiofrequency Ablation: Single-Center Experience(Arquivos Brasileiros Cardiologia, 2024) Topaloğlu, Caner; Fici, Francesco; Van de Borne, Philippe; Taşkın, Uğur; Doğduş, Mustafa; Saygı, Serkan; Tengiz, İstemihanBackground: The ablation of atrioventricular nodal reentrant tachycardia (AVNRT) with cryoablation is an alternative to radiofrequency (RF) ablation in patients due to the low risk of total atrioventricular block.

After the procedure, the patients were evaluated every 3 months for 2 years in polyclinic control. The significance level adopted in the statistical analysis was 5%. Results: The 2 groups of patients were homogeneous. The fluoroscopy time (p<0.001) was shorter, but atrium-his (p=0.004) and his-ventricular (p=0.015) times were longer in the cryoablation group. There was no significant difference, in terms of acute procedural success, post-procedure jump without a single echo, and presence of echo and jump. Conclusions: Cryoablation requires less fluoroscopy time and is a safe non-inferior alternative to RF ablation in patients with AVNRT. The risk of AV block is a significant problem with the use of RF energy, making it less suitable for use in young and physically active patients.
