Frailty Syndrome in cardiovascular disease: clinical significance and research tools.

Frailty Syndrome is one of the key health problems in geriatrics, strongly affecting poor prognosis. There is a growing interest in the relevance of this syndrome in cardiovascular disease. The diagnosis of Frailty Syndrome in the elderly cardiac population is essential for an accurate risk stratification and for making therapeutic decisions. Most risk assessment systems used in cardiology are based on chronological age, which does not always reflect the biological age of a patient, therefore making an inadequate risk estimation. This paper discusses the definitions of Frailty Syndrome and research tools used to identify it. We specifically address the role of Frailty Syndrome in cardiovascular disease and the diagnostic and therapeutic difficulties in patients with Frailty Syndrome, emphasizing the role of the identification of Frailty Syndrome in making therapeutic decisions and the stratification of cardiovascular risk in patients with cardiologic conditions. © The European Society of Cardiology 2015.
