Prevalence and determinants of frailty in older adult patients with chronic coronary syndrome: a cross-sectional study

Abstract

Background Frailty is an expression of vulnerability and decline of physical, mental, and social activities, more commonly found in older adults. It is also closely related to the occurrence and poor prognosis of coronary artery disease (CAD). Little investigation has been conducted on the prevalence and determinants of frailty in older adult patients with chronic coronary syndrome (CCS). Methods A cross-sectional study was conducted, simple random sampling was used in this study. 218 older adults (age\u2009≥\u200960\u2009years) with CCS with an inpatient admission number ending in 6 were randomly selected who hospitalized in Department of Geriatric\xa0Cardiology, Shandong Provincial Hospital Affiliated to Shandong First Medical University, China, between January and December 2018. For measurement and assessment, we used the 5-item FRAIL scale (fatigue, resistance, ambulation, illnesses, and loss of weight), demographic characteristics, Barthel Index(BI), Mini-Mental State Examination (MMSE), Geriatric Depression Scale (GDS-15), Mini Nutrition Assessment Shor-Form (MNA-SF), Morse Fall Scale (MFS), Caprini risk assessment, polypharmacy, and Numerical Rating Scale (NRS). Multivariate logistic regression analysis was used to confirme determinants. Results The FRAIL scale showed 30.3% of the subjects suffered from frailty. Determinants were aging (OR1.12; 95% CI 1.04\u2009~\u20091.62), out-of-pocket (OR18.93; 95% CI 1.11\u2009~\u2009324.07), hearing dysfunction (OR9.43; 95% CI 1.61\u2009~\u200955.21), MNA-SF score (OR0.71; CI 0.57\u2009~\u20090.89), GDS-15 score (OR1.35; 95% CI 1.11\u2009~\u20091.64), and Caprini score (OR1.34; 95% CI 1.06\u2009~\u20091.70). Conclusions The FRAIL scale confirmed that\xa0the prevalence of frailty in patients with CCS was slightly lower than CAD. Aging, malnutrition, hearing dysfunction, depression, and VTE risk were significantly associated with frail for older adult patients with CCS. A comprehensive assessment of high-risk patients can help identify determinants for frailty progression. In the context of CCS, efforts to identify frailty are needed, as are interventions to limit or reverse frailty status in older CCS patients.
