Frailty assessment in the cardiovascular care of older adults.

ABSTRACT: Due to the aging and increasingly complex nature of our patients, frailty has become a high-priority theme in cardiovascular medicine. Despite the recognition of frailty as a pivotal element in the evaluation of older adults with cardiovascular disease (CVD), there has yet to be a road map to facilitate its adoption in routine clinical practice. Thus, we sought to synthesize the existing body of evidence and offer a perspective on how to integrate frailty into clinical practice. Frailty is a biological syndrome that reflects a state of decreased physiological reserve and vulnerability to stressors. Upward of 20 frailty assessment tools have been developed, with most tools revolving around the core phenotypic domains of frailty-slow walking speed, weakness, inactivity, exhaustion, and shrinking-as measured by physical performance tests and questionnaires. The prevalence of frailty ranges from 10% to 60%, depending on the CVD burden, as well as the tool and cutoff chosen to define frailty. Epidemiological studies have consistently demonstrated that frailty carries a relative risk of >2 for mortality and morbidity across a spectrum of stable CVD, acute coronary syndromes, heart failure, and surgical and transcatheter interventions. Frailty contributes valuable prognostic insights incremental to existing risk models and assists clinicians in defining optimal care pathways for their patients. Interventions designed to improve outcomes in frail elders with CVD such as multidisciplinary cardiac rehabilitation are being actively tested. Ultimately, frailty should not be viewed as a reason to withhold care but rather as a means of delivering it in a more patient-centered fashion.

Project description:BackgroundThe contribution of cardiovascular dysfunction to frailty in older adults is uncertain. This study aimed to define the relationship between frailty and cardiovascular structure and function, and determine whether these associations are independent of coexisting abnormalities in other organ systems.MethodsWe studied 3,991 older adults (mean age 75.6±5.0 years; 59% female) from the Atherosclerosis Risk in Communities (ARIC) Study in whom the following six organ systems were uniformly assessed: cardiac (by echocardiography), vascular (by ankle-brachial-index and pulse-wave-velocity), pulmonary (by spirometry), renal (by estimated glomerular filtration rate), hematologic (by hemoglobin), and adipose (by body mass index and bioimpedance). Frailty was defined by the presence of ≥3 of the following: low strength, low energy, slowed motor performance, low physical activity, or unintentional weight loss.ResultsTwo hundred eleven (5.3%) participants were frail. In multivariable analyses adjusted for demographics, diabetes, hypertension, and measures of other organ system function, frailty was independently and additively associated with left ventricular hypertrophy (odds ratio [OR] = 1.72; 95% confidence interval [CI] = 1.30-2.40), reduced global longitudinal strain (reflecting systolic function; OR = 1.68; 95% CI = 1.16-2.44), and greater left atrial volume index (reflecting diastolic function; OR = 1.60; 95% CI = 1.13-2.27), which together demonstrated the greatest association with frailty (OR = 2.10; 95% CI = 1.57-2.82) of the systems studied. Lower magnitude associations were observed for vascular and pulmonary abnormalities, anemia, and impaired renal function. Cardiovascular abnormalities remained associated with frailty after excluding participants with prevalent cardiovascular disease.ConclusionsAbnormalities of cardiac structure and function are independently associated with frailty, and together show the greatest association with frailty among the organ systems studied.

Project description:OBJECTIVES:Despite evidence, frailty is not routinely assessed before cardiac surgery. We compared five brief frailty tests for predicting poor outcomes after aortic valve replacement and evaluated a strategy of performing comprehensive geriatric assessment (CGA) in screen-positive patients. DESIGN:Prospective cohort study. SETTING:A single academic center. PARTICIPANTS:Patients undergoing surgical aortic valve replacement (SAVR) (n = 91; mean age = 77.8 y) or transcatheter aortic valve replacement (TAVR) (n = 137; mean age = 84.5 y) from February 2014 to June 2017. MEASUREMENTS:Brief frailty tests (Fatigue, Resistance, Ambulation, Illness, and Loss of weight [FRAIL] scale; Clinical Frailty Scale; grip strength; gait speed; and chair rise) and a deficit-accumulation frailty index based on CGA (CGA-FI) were measured at baseline. A composite of death or functional decline and severe symptoms at 6 months was assessed. RESULTS:The outcome occurred in 8.8% (n = 8) after SAVR and 24.8% (n = 34) after TAVR. The chair rise test showed the highest discrimination in the SAVR (C statistic = .76) and TAVR cohorts (C statistic = .63). When the chair rise test was chosen as a screening test (?17?s for SAVR and??23?s for TAVR), the incidence of outcome for screen-negative patients, screen-positive patients with CGA-FI of .34 or lower, and screen-positive patients with CGA-FI higher than .34 were 1.9% (n = 1/54), 5.3% (n = 1/19), and 33.3% (n = 6/18) after SAVR, respectively, and 15.0% (n = 9/60), 14.3% (n = 3/21), and 38.3% (n = 22/56) after TAVR, respectively. Compared with routinely performing CGA, targeting CGA to screen-positive patients would result in 54 fewer CGAs, without compromising sensitivity (routine vs targeted: .75 vs .75; P = 1.00) and specificity (.84 vs .86; P = 1.00) in the SAVR cohort; and 60 fewer CGAs with lower sensitivity (.82 vs.65; P = .03) and higher specificity (.50 vs .67; P?<?.01) in the TAVR cohort. CONCLUSIONS:The chair rise test with targeted CGA may be a practical strategy to identify older patients at high risk for mortality and poor recovery after SAVR and TAVR in whom individualized care management should be considered.
