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.
