Öğe Clinical characteristics of atrial fibrillation in nonagenarian population and relationship with mortality(Edizioni Minerva Medica, 2024) Cakan, Fahri; Onalan, Orhan; Adar, Adem; Akbay, Ertan; Colluoglu, Inci T.; Kokturk, Ugur; Akin, YesimBACKGROUND: There is a considerable amount of literature available on well-known risk factors for atrial fibrillation (AF); however, available data specifically focused on the ninth decade are scarce. The main objective of this study was to assess the demographic and clinical characteristics of AF and sinus rhythm in a nonagenarian population. METHODS: All individuals aged >90 years who were admitted to the Cardiology outpatient clinic between April 2018 and January 2019 were enrolled in the study. The demographic and clinical characteristics of all patients were recorded. All deaths that occurred during the two-year follow-up period were recorded. RESULTS: In total, 112 nonagenarian individuals were included in the study. Of these patients, 50 (44.6%) had AF. The groups showed similarities in demographic and clinical characteristics. During a mean follow-up period of 596 +/- 44 days, 39 patients (78%) in the AF group and 35 patients (56.5%) in the sinus group died. Patients with AF showed a lower overall survival distribution than those with sinus rhythm (P=0.005, log-rank test chi 2=7.734). 2 =7.734). AF was associated with an increased risk of mortality (P=0.002, hazard ratio [HR] =2.104, 95% confidence interval [CI] = 1.326-3.339) in multivariate Cox regression analysis, while waist circumference and total cholesterol (P=0.003, HR=0.969, 95% CI=0.949-0.989 and P=0.046, HR=0.993, 95% CI=0.986-1.000, respectively) showed a decreased risk of mortality. CONCLUSIONS: Atrial fibrillation is very common in individuals over the age of 90 years (44.6%). Well-known risk factors do not appear to be effective in this age group, and AF is associated with a 2.1-fold increase in the risk of mortality.Öğe Impact of triglyceride-glucose index on intracoronary thrombus burden in ST-elevation myocardial infarction patients undergoing primary percutaneous coronary intervention(Elsevier Sci Ltd, 2024) Kokturk, Ugur; Onalan, Orhan; Somuncu, Mustafa Umut; Akgul, Ozgur; Uygur, Begum; Pusuroglu, HamdiBackground and aims: We aimed to investigate the relationship between triglyceride glucose (TyG) index and intracoronary thrombus burden in patients with ST-elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI). Methods and results: A total of 468 consecutive patients who were admitted with STEMI and underwent primary PCI were included in the study. TyG index was calculated as ln [fasting triglycerides (mg/dL) x fasting plasma glucose (mg/dL)/2]. According to the angiographic reclassified thrombolysis in myocardial infarction (TIMI) thrombus grade, patients were divided into two groups as small thrombus burden (STB) with TIMI thrombus grade 0-3, and large thrombus burden (LTB) with TIMI thrombus grade 4-5. TyG index was significantly higher in the LTB group than in the STB group (9.11 +/- 0.86 vs 8.89 +/- 0.62; p = 0.002). In multivariate analysis, TyG index was found to be an independent predictor of LTB in STEMI patients who underwent primary PCI [OR (95 % CI): 1.470 (1.090-1.982), p = 0.012]. The area under the curve (AUC) of TyG index predicting LTB was 0.568 (95 % CI 0.506-0.631; p = 0.023), with the best cut-off value of 8.87. In the classification according to TyG index cut-off value, the frequency of LTB was found to be significantly higher in the high TyG index group than in the low TyG index group (33.6 % vs 21.2 %; p = 0.003). Conclusion: TyG index, a valid surrogate marker of insulin resistance, is an independent predictor of LTB in STEMI patients who underwent primary PCI and can be used as an indicator of increased intracoronary thrombus burden.

The relationship between LTB and long-term mortality and major adverse cardiac events (MACE) in STEMI patients undergoing percutaneous coronary intervention (PCI) is unclear. In this study, we aimed to investigate the relationship of LTB with short- and long-term mortality and MACE in STEMI patients undergoing PCI. Methods Thrombus burden (TB) was evaluated in STEMI patients who underwent PCI between December 2010 and April 2012. After infarct-related arterial flow was restored, TB was reclassified. LTB was defined as thrombus with the largest dimension of at least two vessel diameters. Patients were evaluated for 1-month, 1-year, and 10-year follow-ups in terms of MACE and mortality. Results Four hundred ninety-nine patients with clinical information and TB classification were analyzed. Three hundred sixty-six patients (73.3%) were in the small TB (STB) group, and 133 patients (26.7%) were in the LTB group. No-reflow (10.6% vs. 5.2%; P = 0.033) and stent thrombosis (7.5% vs. 3.3%; P = 0.042) were observed at a higher rate in the LTB group compared with the STB group. Thirty-day mortality (9.8% vs. 3.8%; P = 0.009) and MACE (16.5% vs. 9.6%; P = 0.030) were higher in the LTB group than in the STB group. Although 10-year MACE (56.4% vs. 46.2%; P = 0.044) was observed higher in the LTB group, no significant difference was observed between the two groups in terms of 10-year mortality (35.3% vs. 32.8%; P = 0.589). LTB was found to be an independent predictor for 10-year MACE (OR, 1.62; 95% CI, 1.01-2.61; P = 0.045). Conclusion LTB was associated with short- and long-term clinical events in STEMI patients undergoing PCI, but the mortality effect disappeared at the end of 1 year. Nevertheless, hospitalizations due to heart failure became significant in 10-year follow-up.Öğe Relationship between Aortic Arch Calcification, Detected by Chest X-Ray, and Renal Resistive Index in Patients with Hypertension(Karger, 2019) Adar, Adem; Onalan, Orhan; Keles, Hakan; Cakan, Fahri; Kokturk, UgurObjective: Aortic arch calcification (AAC) is a surrogate marker for arterial stiffness and hypertension-related vascular damage. Renal resistive index (RRI), a renal Doppler ultrasonography parameter, is used to assess renal hemodynamics. In this study, we aimed to evaluate the relationship between RRI and AAC in patients with hypertension. Methods: Patients with hypertension underwent a chest X-ray and renal Doppler ultrasonography. They were divided into two groups according to RRI (group 1: RRI >= 0.70; group 2: RRI <0.70). Two examiners, blinded to the findings of RRI, reviewed the AAC in these patients. The kappa value was detected to be 0.781 and a p value <0.001 was considered significant. Results: The study included 289 hypertensive patients (mean age 63.87 +/- 11.38 years). In 53.6% (n = 155) of the study subjects, RRI was observed to be >= 0.70. Patients with RRI = 70 were older and had more prevalent AAC as well as left ventricular hypertrophy. A multiple linear regression analysis was carried out to test whether presence of AAC significantly predicted RRI. The results of the regression analysis indicated that presence of AAC significantly predicted RRI (beta = 0.053; p < 0.001). Conclusions: A strong and independent relationship was found between AAC on chest X-ray and RRI in patients with hypertension. (C) 2018 The Author(s) Published by S. Karger AG, Basel
