This study aims to investigate the prevalence of frailty and its association with six-month clinical outcomes in elderly patients with heart failure and left ventricular ejection fraction greater than 40%. Elderly patients diagnosed with heart failure will be assessed for frailty status and followed up for six months to evaluate outcomes such as hospitalization and mortality. The study is observational and will help improve understanding of the impact of frailty on the prognosis of heart failure patients with ejection fraction \>40%.
