Hypertension, heart failure, and frailty in older people: A common but unclear situation.

Hypertension and heart failure are common conditions in older people. Comorbidity, together with aging, is commonly associated with frailty, which is a cause of a worse prognosis, more hospitalizations, increased dependency, and mortality. Despite being increasingly common conditions, data on the prevalence and influence of frailty in hypertensive older patients with HF are lacking. This may be due to the multidimensional aspects of frailty and the differing tools used to evaluate it. Nevertheless, in clinical practice, it is common to see frail hypertensive patients with HF but the specific characteristics of this group of patients, including multimorbidity and frailty, and the lack of data from registries or randomized clinical trials make the diagnosis and management of these patients more difficult than in those of other ages. This review focuses on what is known and on where future investigations should focus in this common but unclear situation.
