    The Safety and Tolerability of Nebivolol in Hypertensive Patients with Coronary Artery Disease and Left Ventricular Ejection Fraction >= 40%: A Population-Based Cohort Study (Nebivolol-TR Study)
    (2022) Altin, Cihan; Okyay, Kaan; Kocaba, Umut; Coner, Ali; https://orcid.org/0000-0001-6134-8826; https://orcid.org/0000-0002-5711-8873; 36317659; AAK-7355-2020; ABD-7321-2021
    Background: This study aimed to assess the safety and tolerability of nebivolol in hypertensive patients with coronary artery disease and left ventricular ejection fraction >= 40% in a Turkish cohort. Methods: A total of 1015 hypertensive patients and coronary artery disease with left ventricular ejection fraction >= 40% were analyzed from 29 different centers in Turkey. Primary outcomes were the mean change in blood pressure and heart rate. Secondary outcomes were to assess the rate of reaching targeted blood pressure (<130/80 mmHg) and heart rate (<60 bpm) and the changes in the clinical symptoms (angina and dyspnea). Adverse clinical events and clinical outcomes including cardiovascular mortality, cardiovascular hospital admissions, or acute cardiac event were recorded. Results: The mean age of the study population was 60.3 +/- 11.5 years (male: 54.2%). During a mean follow-up of 6 months, the mean change in blood pressure was -11.2 +/- 23.5/-5.1 +/- 13.5 mmHg, and the resting heart rate was -12.1 +/- 3.5 bpm. Target blood pressure and heart rate were achieved in 76.5% and 37.7% of patients. Angina and functional classifications were improved by at least 1 or more categories in 31% and 23.2% of patients. No serious adverse events related to nebivolol were reported. The most common cardiovascular side effect was symptomatic hypotension (4.2%). The discontinuation rate was 1.7%. Cardiovascular hospital admission rate was 5% and hospitalization due to heart failure was 1.9% during 6 months' follow-up. Cardiovascular mortality rate was 0.1%. Conclusion: Nebivolol was well tolerated and safe for achieving blood pressure and heart rate control in hypertensive patients with coronary artery disease and heart failure with preserved or mildly reduced ejection fraction.

    Demographics of patients with heart failure who were over 80 years old and were admitted to the cardiology clinics in Turkey
    (2019) Okyay, Kaan; 30930455; AAK-7355-2020
    Objective: Heart failure (HF) has a high prevalence and mortality rate in elderly patients; however, there are few studies that have focused on patients older than 80 years. The aim of this study is to describe and compare the age-specific demographics and clinical features of Turkish elderly patients with HF who were admitted to cardiology clinics. Methods: The Epidemiology of Cardiovascular Disease in Elderly Turkish population (ELDER-TURK) study was conducted in 73 centers in Turkey, and it recruited a total of 5694 patients aged 65 years or older. In this study, the clinical profile of the patients who were aged 80 years or older and those between 65 and 79 years with HF were described and compared based on the ejection fraction (EF)-related classification: HFrEF and HFpEF (is considered as EF: >= 50%). Results: A total of 1098 patients (male, 47.5%; mean age, 83.5 +/- 3.1 years) aged 80 years and 4596 patients (male, 50.2 %; mean age, 71.1 +/- 4.31 years) aged 65-79 years were enrolled in this study. The prevalence of HF was 39.8% for patients who were >= 80 years and 27.1% for patients 65-79 years old. For patients aged >= 80 years with HF, the prevalence rate was 67% for hypertension (HT), 25.6% for diabetes mellitus (DM), 54.3% for coronary artery disease (CAD), and 42.3% for atrial fibrilation. Female proportion was lower in the HFrEF group (p=0.019). The prevalence of HT and DM was higher in the HFpEF group (p<0.01), whereas CAD had a higher prevalence in the HFrEF group (p=0.02). Among patients aged 65-79 years, 43.9% (548) had HFpEF, and 56.1% (700) had HFrEF. In this group of patients aged 65-79 years with HFrEF, the prevalence of DM was significantly higher than in patients aged >= 80 years with HFrEF (p<0.01). Conclusion: HF is common in elderly Turkish population, and its frequency increases significantly with age. Females, diabetics, and hypertensives are more likely to have HFpEF, whereas CAD patients are more likely to have HFrEF.
