Mild Cognitive Impairment and Receipt of Treatments for Acute Myocardial Infarction in Older Adults.

ABSTRACT:

Background

Older adults with mild cognitive impairment (MCI) should receive evidence-based treatments when indicated. Providers and patients may overestimate the risk of dementia in patients with MCI leading to potential under-treatment. However, the association between pre-existing MCI and receipt of evidence-based treatments is uncertain.

Objective

To compare receipt of treatments for acute myocardial infarction (AMI) between older adults with pre-existing MCI and cognitively normal patients.

Design

Prospective study using data from the nationally representative Health and Retirement Study, Medicare, and American Hospital Association.

Participants

Six hundred nine adults aged 65 or older hospitalized for AMI between 2000 and 2011 and followed through 2012 with pre-existing MCI (defined as modified Telephone Interview for Cognitive Status score of 7-11) and normal cognition (score of 12-27).

Main measures

Receipt of cardiac catheterization and coronary revascularization within 30 days and cardiac rehabilitation within 1 year of AMI hospitalization.

Key results

Among the survivors of AMI, 19.2% had pre-existing MCI (55.6% were women and 44.4% were male, with a mean [SD] age of 82.3 [7.5] years), and 80.8% had normal cognition (45.7% were women and 54.3% were male, with a mean age of 77.1 [7.1] years). Survivors of AMI with pre-existing MCI were significantly less likely than those with normal cognition to receive cardiac catheterization (50% vs 77%; P?ConclusionsPre-existing MCI is associated with lower use of cardiac catheterization and coronary revascularization but not cardiac rehabilitation after AMI.

Project description:Background and purposeOlder patients with pre-existing mild cognitive impairment (MCI) receive less evidence-based care after acute myocardial infarction, however, whether they receive less care after acute ischemic stroke (AIS) is unknown. We compared receipt of guideline-concordant procedures after AIS between older adults with pre-existing MCI and normal cognition.MethodsProspective study of 591 adults ≥65 hospitalized for AIS between 2000 and 2014, and followed through 2015 using data from the nationally representative Health and Retirement Study, Medicare and American Hospital Association. We assessed pre-existing MCI (modified Telephone Interview for Cognitive Status score of 7-11) and normal cognition (score of 12-27). Primary outcome was a composite quality measure representing the number of 4 procedures (carotid imaging, cardiac monitoring, echocardiogram, and rehabilitation assessment) received within 30 days after AIS (ordinal scale with values of 0, 1, 2, 3-4).ResultsAmong survivors of AIS, 26.9% had pre-existing MCI (62.9% were women, with a mean [SD] age of 82.4 [7.7] years), and 73.1% had normal cognition (51.4% were women, with a mean age of 78.4 [7.2] years). Patients with pre-existing MCI, compared to cognitively normal patients, had 39% lower cumulative odds of receiving the composite quality measure (unadjusted cumulative odds ratio, OR, 0.61 [95% CI, 0.43-0.87]; P=0.006). However, this association became non-significant after adjusting for patient and hospital factors (adjusted cumulative OR, 0.83 [95% CI, 0.56-1.24]; P=0.37). Lower cumulative odds of receiving the composite quality measure were associated with older patient age (adjusted cumulative OR per 1-year older age, 0.97 [95% CI, 0.95-0.99]; P=0.01) and Southern hospitals (adjusted cumulative OR for South vs North, 0.54 [95% CI, 0.31-0.94]; P=0.03).ConclusionsDifferences in receipt of guideline-concordant procedures after AIS exist between patients with pre-existing MCI and normal cognition. These differences were largely explained by patient and regional factors associated with receiving less AIS care.

Project description:BackgroundRecent evidence from cross-sectional and longitudinal studies supports the hypothesis that sarcopenia is associated with worsening cognitive function. However, primary evidence largely comes from high-income countries, whereas in low- and middle-income countries, this association has been underexplored. This study aimed to estimate the longitudinal association between sarcopenia and mild cognitive impairment in a sample of older Mexican adults.MethodsData come from the three waves of the World Health Organization (WHO) Study on Global AGEing and Adult Health (SAGE) in Mexico (2009, 2014, 2017). Four hundred ninety-six older adults, aged ≥50, were included. Sarcopenia was defined as having low muscle quantity and either/both slow gait speed and weak handgrip strength. Mild cognitive impairment was determined based on the recommendations of the National Institute on Aging-Alzheimer's Association. Cognitive function was evaluated by a composite cognitive score of five different cognitive tests: immediate and delayed recall, forward and backward digit span and semantic verbal fluency. Three-level mixed-effects models (logistic and linear) were used to estimate the longitudinal associations between sarcopenia, mild cognitive impairment and cognitive function.ResultsThe prevalence of mild cognitive impairment (8.9%, 12.9%, 16.0%) and sarcopenia (10.5%, 20.7%, 23.3%) showed a significant temporal increase for Waves 1, 2 and 3 (P-value < 0.01, respectively). The presence of sarcopenia was significantly associated with mild cognitive impairment (OR = 1.74; CI95% 1.02, 2.96; P = 0.04) and worse cognitive function (β = -0.57; CI95% -0.93, -0.21; P < 0.01). We observed significant associations between sarcopenia and immediate verbal recall (β = -0.14; CI95% -0.28, -0.01; P = 0.04), delayed verbal recall (β = -0.12; CI95% -0.23, -0.01; P = 0.03) and semantic verbal fluency (β = -0.17; CI95% -0.28, -0.05; P = 0.01). The prevalence of mild cognitive impairment increased at an annual rate of 0.8% for non-sarcopenic older adults, but nearly 1.5% for sarcopenic adults.ConclusionsSignificant longitudinal associations were observed between sarcopenia, mild cognitive impairment and cognitive function among older Mexican adults. Public health strategies, including policy research and clinical interventions, must be implemented in low- and middle-income countries in order to reduce or delay the onset of sarcopenia and thus improve population-level cognitive health among older adults.
