Implication of different frailty criteria in older people with atrial fibrillation: a prospective cohort study.

ABSTRACT:

Background

the prevalence of physical and multidimensional frailty and their prognostic impact on clinical outcomes in patients with atrial fibrillation (AF) is unclear.

Objective

to evaluated frailty in a cohort of patients with AF according to different criteria, and studied the prevalence and its prognostic impact on clinical outcomes.

Methods

in this multicenter prospective cohort, 197 inpatients ≥ 65 years old with AF were recruited from September 2018 to April 2019.We used Fried Frailty phenotype (Fried) to assess physical frailty, and comprehensive geriatric assessment-frailty index (CGA-FI) to assess multidimensional frailty. The primary outcome was a composite of all-cause mortality or rehospitalization.

Results

the prevalence of frailty was determined as 34.5% by Fried, 42.6% by CGA-FI. Malnutrition and ≥ 7 medications were independently associated with frailty. Kaplan-Meier survival curve showed that the presence of frailty by CGA-FI had significantly lower all-cause mortality or rehospitalization survival rate (log-rank P = 0.04) within 1 year. Multivariate Cox regression adjusted for age and sex showed that the frailty by CGA-FI was significantly associated with the risk of all-cause mortality or rehospitalization within 1 year (HR 1.79, 95% CI 1.10-2.90). However, those associations were absent with the physical frailty. After broader multivariate adjustment, those associations were no longer statistically significant for both types of frailty.

Conclusions

in older people with AF, Multidimensional frailty is more significantly associated with a composite of all-cause mortality or rehospitalization within 1 year than physical frailty, but these association are attenuated after multivariate adjustment.

Project description:Background/objectivesOral anticoagulation (OAC) is challenging in older patients with nonvalvular atrial fibrillation (NVAF) who are often frail and have cognitive impairment. We examined the characteristics of older NVAF patients associated with higher odds of physical and cognitive impairments. We also examined if these high-risk patients have different OAC prescribing patterns and their satisfaction with treatment because it may impact optimal management of their NVAF.MethodsThe patients in the Systematic Assessment of Geriatric Elements in Atrial Fibrillation (SAGE-AF study cohort 2016-2018) had NVAF, were aged 65 and older, and eligible for the receipt of OAC. Measures included frailty (Fried Frailty scale), cognitive impairment (Montreal Cognitive Assessment Battery), OAC prescribing and type (direct oral anticoagulant [DOAC] or vitamin K antagonist [VKA]), depressive symptoms (Patient Health Questionnaire-9), bleeding, stroke risk, and treatment benefit (Anti-Clot Treatment Scale).ResultsPatients (n = 1,244) were 49% female, aged 76 (standard deviation = 7) years. A total of 14% were frail, and 42% had cognitive impairment. Frailty and cognitive impairment co-occurred in 9%. Odds of having both impairments versus none were higher with depression (odds ratio [OR] = 4.62; 95% confidence interval [CI] = 2.59-8.26), older age (OR = 1.56; 95% CI = 1.29-1.88), lower education (OR = 3.81; 95%CI = 2.13-6.81), race/ethnicity other than non-Hispanic White (OR = 7.94; 95% CI = 4.34-14.55), bleeding risk (OR = 1.43; 95% CI = 1.12-1.81), and stroke risk (OR = 1.35; 95% CI = 1.13-1.62). OAC prescribing was not associated with CI and frailty status. Among patients taking OACs (85%), those with both impairments were more likely to take DOAC than VKA (OR = 1.69; 95% CI = 1.01-2.80). Having both impairments (OR = 1.87; 95% CI = 1.08-3.27) or cognitive impairment (OR = 1.56; 95% CI = 1.09-2.24) was associated with higher odds of reporting lower treatment benefit.ConclusionIn a large cohort of older NVAF patients, half were frail or cognitively impaired, and 9% had both impairments. We highlight the characteristics of patients who may benefit from cognitive and physical function screenings to maximize treatment and enhance prognosis. Finally, the co-occurrence of impairment was associated with low perceived benefit of treatment that may impede optimal management.

Project description:BackgroundThe role of differing levels of frailty in the choice of oral anticoagulants for older adults with atrial fibrillation (AF) is unclear.ObjectiveTo examine the outcomes of direct oral anticoagulants (DOACs) versus warfarin by frailty levels.Design1:1 propensity score-matched analysis of Medicare data, 2010 to 2017.SettingCommunity.PatientsMedicare beneficiaries with AF who initiated use of dabigatran, rivaroxaban, apixaban, or warfarin.MeasurementsComposite end point of death, ischemic stroke, or major bleeding by frailty levels, defined by a claims-based frailty index.ResultsIn the dabigatran-warfarin cohort (n = 158 730; median follow-up, 72 days), the event rate per 1000 person-years was 63.5 for dabigatran initiators and 65.6 for warfarin initiators (hazard ratio [HR], 0.98 [95% CI, 0.92 to 1.05]; rate difference [RD], -2.2 [CI, -6.5 to 2.1]). For nonfrail, prefrail, and frail persons, HRs were 0.81 (CI, 0.68 to 0.97), 0.98 (CI, 0.90 to 1.08), and 1.09 (CI, 0.96 to 1.23), respectively. In the rivaroxaban-warfarin cohort (n = 275 944; median follow-up, 82 days), the event rate per 1000 person-years was 77.8 for rivaroxaban initiators and 83.7 for warfarin initiators (HR, 0.98 [CI, 0.94 to 1.02]; RD, -5.9 [CI, -9.4 to -2.4]). For nonfrail, prefrail, and frail persons, HRs were 0.88 (CI, 0.77 to 0.99), 1.04 (CI, 0.98 to 1.10), and 0.96 (CI, 0.89 to 1.04), respectively. In the apixaban-warfarin cohort (n = 218 738; median follow-up, 84 days), the event rate per 1000 person-years was 60.1 for apixaban initiators and 92.3 for warfarin initiators (HR, 0.68 [CI, 0.65 to 0.72]; RD, -32.2 [CI, -36.1 to -28.3]). For nonfrail, prefrail, and frail persons, HRs were 0.61 (CI, 0.52 to 0.71), 0.66 (CI, 0.61 to 0.70), and 0.73 (CI, 0.67 to 0.80), respectively.LimitationsResidual confounding and lack of clinical frailty assessment.ConclusionFor older adults with AF, apixaban was associated with lower rates of adverse events across all frailty levels. Dabigatran and rivaroxaban were associated with lower event rates only among nonfrail patients.Primary funding sourceNational Institute on Aging.

Project description:BackgroundPeople with HIV (PWH) have increased frailty risk at younger ages compared with the general population. Multimorbidity is associated with frailty, yet effects of specific comorbidities on transition to frailty in PWH are unknown.SettingProspective study of 219 PWH age 45 years or older in the National NeuroAIDS Tissue Consortium.MethodsFrailty status was categorized using Fried frailty phenotype criteria. Comorbidities [bone disease, cardiovascular disease, cerebrovascular disease, liver disease, renal disease, diabetes, chronic obstructive pulmonary disease (COPD), hypertension, obesity, cancers, neuropsychiatric conditions] were assessed from longitudinal data. Associations between baseline comorbidities and transition to frailty within 30 months were analyzed using Kaplan-Meier and Cox regression models. Grip strength was assessed using mixed-effects models.ResultsAt baseline, the median age was 61 years, 73% were male 98% were on antiretroviral therapy, 29% had ≥3 comorbidities, 27% were robust, and 73% were pre-frail. Cerebrovascular disease, diabetes, and COPD were independent predictors of transition to frailty within 30 months in models adjusted for age, sex, and multimorbidity (≥3 additional comorbidities) [hazard ratios (95% confidence intervals) 2.52 (1.29 to 4.93), 2.31 (1.12 to 4.76), and 1.82 (0.95 to 3.48), respectively]. Furthermore, cerebrovascular disease, diabetes, COPD, or liver disease co-occurring with multimorbidity was associated with substantially increased frailty hazards compared with multimorbidity alone (hazard ratios 4.75-7.46). Cerebrovascular disease was associated with decreased baseline grip strength (P = 0.0001), whereas multimorbidity, diabetes, and COPD were associated with declining grip strength (P < 0.10).ConclusionsIn older PWH, cerebrovascular disease, diabetes, COPD, or liver disease co-occurring with multimorbidity is associated with substantially increased risk of becoming frail within 30 months. Interventions targeting these comorbidities may ameliorate frailty and age-related functional decline in PWH.

Project description:BackgroundAtrial myopathy-characterized by changes in left atrial function and size-may precede and promote atrial fibrillation (AF) and cardiac thromboembolism. In people without prior AF or stroke, whether analysis of left atrial function and size can improve ischemic stroke prediction is unknown.ObjectiveTo evaluate the association of echocardiographic left atrial function (reservoir, conduit, and contractile strain) and left atrial size (left atrial volume index) with ischemic stroke and determine whether these measures can improve the stroke prediction achieved by CHA2DS2-VASc score variables.DesignProspective cohort study.SettingARIC (Atherosclerosis Risk in Communities) study.Participants4917 ARIC participants without prevalent stroke or AF.MeasurementsIschemic stroke events (2011 to 2019) were adjudicated by physicians. Left atrial strain was measured using speckle-tracking echocardiography.ResultsOver 5 years, the cumulative incidences of ischemic stroke in the lowest quintiles of left atrial reservoir, conduit, and contractile strain were 2.99% (95% CI, 1.89% to 4.09%), 3.18% (CI, 2.14% to 4.22%), and 2.15% (CI, 1.09% to 3.21%), respectively, and that of severe left atrial enlargement was 1.99% (CI, 0.23% to 3.75%). On the basis of the Akaike information criterion, left atrial reservoir strain plus CHA2DS2-VASc variables was the best predictive model. With the addition of left atrial reservoir strain to CHA2DS2-VASc variables, 11.6% of the 112 participants with stroke after 5 years were reclassified to higher risk categories and 1.8% to lower risk categories. Among the 4805 participants who did not develop stroke, 12.2% were reclassified to lower and 12.7% to higher risk categories. Decision curve analysis showed a predicted net benefit of 1.34 per 1000 people at a 5-year risk threshold of 5%.LimitationUnderascertainment of subclinical AF.ConclusionIn people without prior AF or stroke, when added to CHA2DS2-VASc variables, left atrial reservoir strain improves stroke prediction and yields a predicted net benefit, as shown by decision curve analysis.Primary funding sourceNational Heart, Lung, and Blood Institute of the National Institutes of Health.
