Öğe Can Diastolic Dysfunction Develop as a Result of Premature Ventricular Complex?(Kare Publ, 2023) Koseoglu, Cemal; Oncel, Can Ramazan[Abstract Not Available]Öğe Clinical Importance of P Wave Dispersion in Mitral Valve Prolapse(Erciyes Univ Sch Medicine, 2024) Oncel, Can Ramazan; Koseoglu, Cemal; Coner, AliObjective: Mitral valve prolapse (MVP) is a widespread valvulopathy present in 2-6% of the population, affecting more than 170 million people globally. The objective of this study was to assess P wave dispersion (PWD) in patients with MVP to identify the presence of cardiovascular autonomic dysfunction and the potential risk of developing atrial arrhythmias in these patients. Materials and Methods: The study included 40 healthy control participants (Group 1), 41 patients with non-classic MVP (Group 2), and 36 patients with classic MVP (Group 3). Demographic and clinical characteristics were documented upon admission. An electrocardiographic assessment was conducted to quantify PWD values for both patients and the control group. Results: The minimum P wave duration was lower in classic MVP patients than in controls and non-classic MVP patients (63 +/- 3.6 vs. 70 +/- 2.0, p<0.001; 63 +/- 3.6 vs. 63 +/- 3.6, p<0.001, respectively). P wave dispersion was higher in classic MVP patients than in non-classic MVP patients (47.3 +/- 3.2 vs. 39.0 +/- 2.3, p=0.001). A significant positive correlation was detected between PWD and maximum P wave duration (Pmax), minimum P wave duration (Pmin), maximal leaflet displacement, maximal leaflet thickness, and left atrial diameter (LAD) (r=0.723, p<0.001; r=-0.771, p<0.001; r=0.557, p<0.001; r=0.770, p<0.001; r=0.517, p<0.001, respectively). Maximum leaflet thickness and maximum leaflet displacement were independent predictors of increased PWD in linear regression analysis (beta=1.456, p<0.001, beta=-0.851, p<0.001). Conclusion: Patients with classic MVP exhibited prolonged PWD values compared with non-classic MVP patients and normal controls.Öğe Determining ECG Parameters for Electrical Risk Score in Patients with Non-ST Elevation Myocardial Infarction(Kare Publ, 2025) Oncel, Can Ramazan; Coner, Ali; Koseoglu, Cemal[Abstract Not Available]Öğe Dual Antiplatelet Therapy Duration May Affect the Clinical Outcomes in Older Patients with Acute Coronary Syndrome(Taiwan Soc Cardiology, 2025) Oncel, Can Ramazan; Koseoglu, Cemal; Coner, Ali[Abstract Not Available]Öğe Factors Affecting QT Interval in Patients with Type 2 Diabetes Mellitus and the Effect of Sodium-Glucose Cotransporter 2 Inhibitors(Kare Publ, 2025) Coner, Ali; Oncel, Can Ramazan; Koseoglu, Cemal[Abstract Not Available]Öğe Management of Ventricular Pseudoaneurysms(Kare Publ, 2024) Koseoglu, Cemal; Oncel, Can Ramazan[Abstract Not Available]Öğe Mitral annular plane systolic excursion (MAPSE) as a predictor of atrial fibrillation development after coronary artery bypass surgery(Aepress Sro, 2024) Koseoglu, Cemal; Oncel, Can Ramazan; Dagasan, Goksel; Coner, Ali; Akkaya, Ozgur; Keykubat, Alanya AlaaddinOBJECTIVE: To predict the possibility of postoperative atrial fibrillation (AF) with mitral annular plane systolic excursion (MAPSE) measurement, which is a cheap, reproducible echocardiographic method and to monitor these patients more closely and to evaluate them more effectively postoperatively. MATERIAL AND METHODS: 247 patients scheduled for coronary artery bypass surgery were evaluated and 200 patients were included in the study. The enrolled patients were classified into the two groups according to the occurrence of postoperative AF or maintained sinus rhythm after coronary artery bypass surgery (normal sinus rhythm [NSR] group vs. AF group).The clinical and demographic data of all the patients were recorded on admission. Two-dimensional transthoracic echocardiography (TTE) was performed prior to elective surgery. RESULTS: Postoperative new onset AF occurred in 37 (18.5%) patients. In the multivariate logistic regression analysis carried out after the formation of the model based on the parameters related to AF development, the relationships with white blood cell count, LAd and MAPSE were observed to be prevalent. When MAPSE, which is a parameter used to predict the development of postoperative atrial fibrillation, was compared in the ROC analysis, the area under the curve was found to be 0.831, 95% CI lower-95% CI upper (0.761-0.901) (p<0.001). The distinguishing MAPSE value in predicting postoperative atrial fibrillation development was found to be 11.6 (sensitivity: 90%, specificity: 81%). CONCLUSIONS: We showed that MAPSE could play a role in determining postoperative atrial fibrillation development after coronary artery bypass surgery (Tab. 2, Fig. 2, Ref. 28).

The ability to accurately identify patients at risk through previous risk scores is limited. This study aimed to evaluate the new HARMS(2)-AF risk score to predict POAF after coronary artery bypass grafting (CABG) surgery. Methods In this retrospective cohort study, we included 265 patients undergoing CABG surgery from 2022-2023. Data were obtained from the medical files of the patients and hospital records. Each patient was assigned a HARMS(2)-AF risk score. A univariate and multivariate regression analyses were done to analyze independent predictors of POAF. Results Of 265 patients, 49 had postoperative atrial fibrillation. HARMS(2)-AF score was significantly higher in patients with POAF. Age, sleep apnea, left atrial diameter (LAd), and HARMS(2)-AF score were independently associated with POAF. A HARMS(2)-AF score >= 4.5 predicted POAF with 91% sensitivity and 64% specificity (AUC = 0.787, 95% CI = 0.731-0.842, P < .001). Conclusion The HARMS(2)-AF score is a strong predictor of atrial fibrillation (AF) development after isolated CABG surgery. It can be used as a novel stratification tool to estimate AF after cardiac surgery.Öğe Re: Factors associated with favorable outcomes in cardiac arrest and target temperature management by Kimura et al.(Mary Ann Liebert, Inc, 2024) Coner, Ali; Koseoglu, Cemal; Oncel, Can Ramazan; Dagasan, Goksel[Abstract Not Available]Öğe Resting Blood Pressure is an Essential Determinant of Blood Pressure Response to Exercise(Wolters Kluwer Medknow Publications, 2024) Coner, Ali; Oncel, Can Ramazan; Koseoglu, Cemal; Dagasan, Goksel[Abstract Not Available]Öğe Should Ticagrelor Be Used with Caution in Patients with Low FEV1/FVC?(Taiwan Soc Cardiology, 2023) Oncel, Can Ramazan; Koseoglu, Cemal[Abstract Not Available]Öğe The possible role of disrupted circadian blood pressure rhythm and excess early morning blood pressure surge in the prediction of future hypertension and hypertension-related target organ damage in patients with a high normal blood pressure profile(Lippincott Williams & Wilkins, 2025) Koseoglu, Cemal; Oncel, Can Ramazan; Coner, Ali[Abstract Not Available]Öğe The protective role of dapagliflozin on the noreflow phenomenon in type 2 diabetic patients with acute coronary syndrome undergoing percutaneous coronary intervention(Taylor & Francis Ltd, 2025) Koseoglu, Cemal; Coner, Ali; Oncel, Can Ramazan[Abstract Not Available]
