    Characterization of Echocardiographic Measures of Cardiac Structure and Function in Healthy Octogenarians
    (2014) Balcioglu, Akif Serhat; Durakoglugil, Murtaza Emre; Okyay, Kaan; Tavil, Yusuf; Abaci, Adnan; https://orcid.org/0000-0001-6134-8826; https://orcid.org/0000-0001-5268-4262; 24506515; Q-3547-2019; AAK-7355-2020
    Background: Currently, there is not enough echocardiographic information regarding aging-associated changes in the octogenarian population. We aimed to characterize echocardiographic measures of structure and function among a group of healthy octogenarians. Methods: Approximately 350 octogenarians, residing in nursing homes, were screened in Ankara, Turkey. According to inclusion criteria, 40 octogenarians were enrolled. These subjects underwent conventional and tissue Doppler echocardiography according to the guidelines of the American Society of Echocardiography (ASE). The population was also separated into various groups according to gender, body mass index (BMI, <25 vs. 25-29.9), and blood pressure (<80/120 mmHg vs. 80-89/120-139 mmHg). All measurements were indexed by dividing to body surface area (BSA) for standardization. Results: Left ventricular mass (LVM), posterior wall thickness, right ventricular diameter, tricuspid E/A ratio, and septal e'-wave velocity were significantly higher in men, which lost significance after adjusting for BSA. There was no significant difference between groups formed by BMI and blood pressure. Moreover, mild global left and right ventricular dysfunction including a prominent diastolic counterpart, however, with normal ejection fraction was revealed using conventional and tissue Doppler techniques. Finally, we checked our results with the current reference values of the ASE and observed the following differences: ventricular septum, relative wall thickness, LVM, and mass index values were above ASE reference range, posterior wall measurements were close to upper range. On the contrary, left ventricular diameters and volumes were below ASE reference range. Conclusions: We described echocardiographic measures of structure and function in a group of healthy octogenarians.

    Comparison of non-vitamin K antagonist oral anticoagulants and well-controlled warfarin in octogenarians with non-valvular atrial fibrillation: Real-world data from a single tertiary center
    (2021) Akgun, Arzu Neslihan; Karacaglar, Emir; Bal, Uğur Abbas; Ozin, Mehmet Bulent; 34236320
    Objective: Atrial fibrillation (AF) is the most common arrhythmia in clinical practice, and its prevalence increases with age. Nevertheless, data about the use of oral anticoagulants (OACs) among patients with >= 80 years remains limited. This study aimed to evaluate the efficacy and safety of non-vitamin K antagonist oral anticoagulants (NOACs) and warfarin in octogenarians with non-valvular AF (NVAF). Methods: Medical records of 387 patients who were >= 80 years and diagnosed with NVAF in our hospital between January 2017 and December 2019 were evaluated retrospectively. Patients with NVAF were divided into 2 groups (NOACs and warfarin), and the incidence of stroke/systemic embolism and major bleeding were analyzed. Results: A total of 322 patients were included in the study. The median follow-up duration was 10.9 months for the NOACs group and 12.1 months for the warfarin group. The primary efficacy outcome was stroke/systemic embolism, and the primary safety outcome was major bleeding. A total of 220 patients were taking NOACs, and the most preferred NOACs were apixaban (53.6%), rivaroxaban (29.5%), dabigatran (13.2%), and edoxaban (3.6%) in this order. During a mean follow-up of 302.7 patient-years, the incidence of stroke or systemic embolic events was slightly higher among patients with warfarin but the difference was not statistically significant (p=0.862). The incidence rates of major bleeding events were similar between the treatment groups (p=0.824). Conclusion: Our study revealed that the safety and efficacy outcomes are similar between the 2 treatment groups in octogenarians with NVAF.
