How do we define high and low dose intensity of heart failure medications: a scoping review.

BACKGROUND: Older adults with heart failure often experience adverse drug events with high doses of heart failure medications. Recognizing whether a patient is on a high or low dose intensity heart failure medication can be helpful for daily practice, since it could potentially guide the physician on which symptoms to look for, whether from overdosing or underdosing. However, the current guideline does not provide sufficient information about the dose intensity below the target dose. Furthermore, the definition of high or low-intensity heart failure medication is unclear, and there is no consensus. METHODS: To close the knowledge gap, we conducted a scoping review of the current literature to identify the most frequently used definition of high versus low doses of heart failure medications. We searched Pubmed, Embase, CINAHL, and Cochrane Library using comprehensive search terms that can capture the intensity of heart failure medications. RESULTS: We reviewed 464 articles, including 144 articles that had information about beta-blockers (BB), 179 articles about angiotensin-converting enzyme inhibitors (ACEi), 75 articles about angiotensin receptor blockers (ARB), 80 articles about diuretics, 37 articles about mineralocorticoid receptor antagonists (MRA), and 33 articles about angiotensin receptor-neprilysin inhibitor (ARNI). For hydralazine with isosorbide dinitrate or ivabradine, we could not identify any eligible articles. We identified 40 medications with most frequently used definitions of dose intensity. Four medications (nadolol, pindolol, cilazapril, and torsemide) did not reach consensus in definitions. Most of the BBs, ACEis, or ARBs used the definition of low being < 50% of the target dose and high being ≥ 50% of the target dose from the guideline. However, for lisinopril and losartan, the most commonly used definitions of high or low were from pivotal clinical trials with a pre-defined definition of high or low. CONCLUSION: Our comprehensive scoping review studies identified the most frequently used definition of dose intensity for 40 medications but could not identify the definitions for 4 medications. The results of the current scoping review will be helpful for clinicians to have awareness whether the currently prescribed dose is considered high - requiring close monitoring of side effects, or low - requiring more aggressive up-titration.

Prescribing patterns of fall risk-increasing drugs in older adults hospitalized for heart failure.

BACKGROUND: Older adults hospitalized for heart failure (HF) are at risk for falls after discharge. One modifiable contributor to falls is fall risk-increasing drugs (FRIDs). However, the prevalence of FRIDs among older adults hospitalized for HF is unknown. We describe patterns of FRIDs use and examine predictors of a high FRID burden. METHODS: We used the national biracial REasons for Geographic and Racial Differences in Stroke (REGARDS) study, a prospective cohort recruited from 2003-2007. We included REGARDS participants aged ≥ 65 years discharged alive after a HF hospitalization from 2003-2017. We determined FRIDs -cardiovascular (CV) and non-cardiovascular (non-CV) medications - at admission and discharge from chart abstraction of HF hospitalizations. We examined the predictors of a high FRID burden at discharge via modified Poisson regression with robust standard errors. RESULTS: Among 1147 participants (46.5% women, mean age 77.6 years) hospitalized at 676 hospitals, 94% were taking at least 1 FRID at admission and 99% were prescribed at least 1 FRID at discharge. The prevalence of CV FRIDs was 92% at admission and 98% at discharge, and the prevalence of non-CV FRIDs was 32% at admission and discharge. The most common CV FRID at admission (88%) and discharge (93%) were antihypertensives; the most common agents were beta blockers (61% at admission, 75% at discharge), angiotensin-converting enzyme inhibitors (36% vs. 42%), and calcium channel blockers (32% vs. 28%). Loop diuretics had the greatest change in prevalence (53% vs. 72%). More than half of the cohort (54%) had a high FRID burden (Agency for Healthcare Research and Quality (AHRQ) score ≥ 6), indicating high falls risk after discharge. In a multivariable Poisson regression analysis, the factors strongly associated with a high FRID burden at discharge included hypertension (PR: 1.41, 95% CI: 1.20, 1.65), mood disorder (PR: 1.24, 95% CI: 1.10, 1.38), and hyperpolypharmacy (PR: 1.88, 95% CI: 1.64, 2.14). CONCLUSIONS: FRID use was nearly universal among older adults hospitalized for HF; more than half had a high FRID burden at discharge. Further work is needed to guide the management of a common clinical conundrum whereby guideline indications for treating HF may contribute to an increased risk for falls.

Underutilization of Endovascular Therapy in Black Patients With Ischemic Stroke: An Analysis of State and Nationwide Cohorts.

BACKGROUND AND PURPOSE: Endovascular therapy (EVT) is a very effective treatment but relies on specialized capabilities that are not available in every hospital where acute ischemic stroke is treated. Here, we assess whether access to and utilization of this therapy has extended uniformly across racial and ethnic groups. METHODS: We conducted a retrospective, population-based study using the 2019 Texas Inpatient Public Use Data File. Acute ischemic stroke cases and EVT use were identified using the International Classification of Diseases, Tenth Revision (ICD-10) diagnosis and procedure codes. We examined EVT utilization by race/ethnicity and performed patient- and hospital-level analyses. To validate state-specific findings, we conducted patient-level analyses using the 2017 National Inpatient Sample for national estimates. To assess independent associations between race/ethnicity and EVT, multivariable modified Poisson regressions were fitted and adjusted relative risks were estimated accounting for patient risk factors and socioeconomic characteristics. RESULTS: Among 40 814 acute ischemic stroke cases in Texas in 2019, 54% were White, 17% Black, and 21% Hispanic. Black patients had similar admissions to EVT-performing hospitals and greater admissions to comprehensive stroke centers (CSCs) compared with White patients (EVT 62% versus 62%, P=0.21; CSCs 45% versus 39%, P<0.001) but had lower EVT rates (4.1% versus 5.3%; adjusted relative risk, 0.76 [0.66-0.88]; P<0.001). There were no differences in EVT rates between Hispanic and White patients. Lower rates of EVT among Black patients were consistent in the subgroup of patients who arrived in early time windows and received intravenous recombinant tissue-type plasminogen activator (adjusted relative risk, 0.77 [0.61-0.98]; P=0.032) and the subgroup of those admitted to EVT-performing hospitals in both non-CSC (3.0% versus 5.5, P<0.001) and CSC hospitals (7.9% versus 10.4%, P<0.001) while there were no differences between Whites and Hispanic patients. Nationwide sample data confirmed this finding of lower utilization of EVT among Black patients (adjusted relative risk, 0.87 [0.77-0.98]; P=0.024). CONCLUSIONS: We found no evidence of disparity in presentation to EVT-performing hospitals or CSCs; however, lower rates of EVT were observed in Black patients.

Prescriptions for Potentially Inappropriate Medications from the Beers Criteria Among Older Adults Hospitalized for Heart Failure.

BACKGROUND: We sought to better understand patterns of potentially inappropriate medications (PIMs) from the Beers criteria among older adults hospitalized with heart failure (HF). This observational study of hospitalizations was derived from the geographically diverse REasons for Geographic and Racial Differences in Stroke cohort. METHODS AND RESULTS: We examined participants aged 65 years and older with an expert-adjudicated hospitalization for HF. The Beers criteria medications were abstracted from medical records. The prevalence of PIMs was 61.1% at admission and 64.0% at discharge. Participants were taking a median of 1 PIM (interquartile range [IQR] 0-1 PIM) at hospital admission and a median of 1 PIM (IQR 0-2 PIM) at hospital discharge. Between admission and discharge, 19.1% of patients experienced an increase in the number of PIMs, 15.1% experienced a decrease, and 37% remained on the same number between hospital admission and discharge. The medications with the greatest increase from admission to discharge were proton pump inhibitors (32.6% to 38.6%) and amiodarone (6.2% to 12.2%). The strongest determinant of potentially harmful prescribing patterns was polypharmacy (relative risk 1.34, 95% confidence interval 1.16-1.55, P < .001). CONCLUSIONS: PIMs are common among older adults hospitalized for HF and may be an important target to improve outcomes in this vulnerable population.

Measures of Frailty in Homebound Older Adults.

OBJECTIVES: Frailty, a geriatric syndrome associated with high morbidity and mortality, has rarely been assessed in homebound older adults. As such, we evaluated the prevalence of frailty among older adults enrolled in a home-based primary care program. METHODS: We measured frailty using the Fried Frailty Phenotype criteria of unintentional weight loss, weakness, poor endurance, slowness, and low physical activity. RESULTS: Of 25 homebound patients (average age 73), 14 (56%) were frail, 11 (44%) were prefrail, and none (0%) were robust. Among those who took ≥5 medications, 63% were frail and 37% were prefrail, and among those who had ≥10 comorbidities, 57% were frail and 43% were prefrail. We also observed that frailty in our homebound older adults was mainly driven by slow gait speed. CONCLUSIONS: Frailty is prevalent in homebound older adults and may be related to slower gait speed, polypharmacy, and/or multimorbidity.

Delirium Among Hospitalized Older Adults With Acute Heart Failure Exacerbation.

BACKGROUND: Delirium among older adults hospitalized with acute heart failure is associated with increased mortality. However, studies concomitantly assessing the association of delirium with both clinical and economic outcomes in this population, such as mortality, hospital cost, or length of stay, are lacking. METHODS AND RESULTS: We conducted a retrospective observational study using National Inpatient Sample data from 2011 to 2014. Using multivariable logistic regression, we assessed the association of delirium with in-hospital mortality, then estimated the incremental hospital cost and excessive length of stay adjusting for demographic and clinical factors using multivariable generalized linear regression. The association of other medical complications on clinical and economic outcomes was also assessed. A total of 568,565 (weighted N = 2,826,131) hospitalizations of patients 65 years or older with acute heart failure from 2011 to 2014 were included in the final analysis. The reported prevalence of delirium was 4.53%. After multivariable adjustment, delirium was associated with a 2.35-fold increase in the odds of in-hospital mortality (95% confidence interval [CI] 2.23-2.47), which was lower than the odds ratio for sepsis/septicemia (5.36; 95% CI, 5.02-5.72) or respiratory failure (4.53; 95% CI, 4.38-4.69), but similar to that for acute kidney injury (2.39; 95% CI, 2.31-2.48) and higher than for non-ST elevation myocardial infarct (1.57; 95% CI, 1.46-1.68). Delirium increased the total hospital cost by $4,262 (95% CI, $4,002-4,521) and the length of stay by 1.73 days (95% CI, 1.68-1.78), which was slightly lower than, but similar to, acute kidney injury ($4,771; 95% CI, $4,644-4,897) and 1.82 days (95% CI, 1.79-1.84), and higher than non-ST elevation myocardial infarct ($1,907; 95% CI, $1,629-2,185) and 0.31 days (95% CI, 0.25-0.37). CONCLUSIONS: Delirium was associated with increased in-hospital mortality, total hospital cost, and length of stay, and the magnitude of the effect was similar to that for acute kidney injury. Enhanced efforts to prevent delirium are needed to decrease its adverse impact on clinical and economic outcomes for hospitalized older adults with acute heart failure.

Association Between Early Tracheostomy and Delirium in Older Adults in the United States.

OBJECTIVES: Early tracheostomy (fewer than eight days after intubation) is associated with shorter length of stay in the intensive care unit and shorter duration of mechanical ventilation. Studies assessing the association between early tracheostomy and incidence of delirium, however, are lacking. This investigation sought to fill this gap. DESIGN: Retrospective cross-sectional study. SETTING: Multi-institutional acute care facilities in the United States. PARTICIPANTS: Data were derived from the National Inpatient Sample data from 2010 to 2014. Included patients were 65 or older and underwent both intubation and tracheostomy during the hospitalization. The authors excluded patients who underwent multiple intubations or tracheostomy procedures. INTERVENTIONS: Early tracheostomy versus non-early tracheostomy. RESULTS: In total, 23,310 patients were included, of whom 24.8% underwent early tracheostomy. From multivariate logistic regression, early tracheostomy was associated with lower odds of having a delirium diagnosis (odds ratio [OR] 0.77, p < 0.00001) across all admission classifications. Upon subgroup analysis, early tracheostomy was associated significantly with lower odds of having delirium for patients admitted with medical (OR 0.74, p < 0.00001) and nonsurgical injury admissions (OR 0.74, p = 0.00116). CONCLUSIONS: Early tracheostomy was associated significantly with lower odds of delirium among all patients studied. This association held true across medical and nonsurgical subgroups.

Community Characteristics Associated With Seeking Medical Evaluation for Suspected Child Sexual Abuse in Greater Houston.

Child sexual abuse (CSA) affects over 62,000 children annually in the United States. A primary obstacle to the success of a public health prevention strategy is the lack of knowledge around community level risk factors for CSA. We evaluated community level characteristics for children seeking care for suspected CSA in the Greater Houston area for 2009. There was a total incidence rate of medical evaluations for suspected CSA of 5.9/1000 children. We abstracted the medical charts of 1982 (86 %) children who sought a medical evaluation for suspected CSA at three main medical systems in the Greater Houston area for 2009. We evaluated 18 community level variables from the American Community Survey for the 396 zip codes these children lived in. The mean number of cases per Greater Houston zip code was 2.77 (range 0-27), with 62 % of zip codes not having a case at any of the three sites surveyed. Zip codes with a higher than Houston average rate of vacant houses, never married females and unemployed labor force with high family poverty rate, were associated with an increased rate of children seeking care for suspected CSA. We demonstrated zip codes level characteristics which were associated with an increased rate of children seeking care for suspected CSA. Our modelling process and our data have implications for community based strategies aimed at improved surveillance or prevention of CSA. The process of identifying locally specific community level factors suggests target areas which have particular socioeconomic characteristics which are associated with increased rate of seeking CSA evaluations.

Definition of Polypharmacy in Heart Failure: A Scoping Review of the Literature.

Patients with heart failure (HF) have a high prevalence of polypharmacy, which can lead to drug interactions, cognitive impairment, and medication non-compliance. However, the definition of polypharmacy in these patients is still inconsistent. The aim of this scoping review was to find the most common definition of polypharmacy in HF patients. We conducted a scoping review searching Medline, Embase, CINAHL, and Cochrane using terms including polypharmacy, HF and deprescribing, which resulted in 7,949 articles. Articles without a definition of polypharmacy in HF patients and articles which included patients < 18 years of age were excluded; only 59 articles were included. Of the 59 articles, 49% (n = 29) were retrospective, 20% (n = 12) were prospective, 10% (n = 6) were cross-sectional, and 27% (n = 16) were review articles. Twenty percent (n = 12) of the articles focused on HF with reduced ejection fraction, 10% (n = 6) focused on HF with preserved ejection fraction and 69% (n = 41) articles either focused on both diagnoses or did not clarify the specific type of HF. The most common cutoff for polypharmacy in HF was five medications (59%, n = 35). There was no consensus regarding the inclusion or exclusion of over-the-counter medications, supplements, or vitamins. Some newer studies used a cutoff of 10 medications (14%, n = 8), and this may be a more practical and meaningful definition for HF patients.

Impact of Frailty and Delirium Among Older Adults Admitted With Acute Decompensated Heart Failure.

Background: The presence of frailty or delirium among patients hospitalized for acute decompensated heart failure (ADHF) is associated with increased mortality and prolonged hospital stay. Objectives: The purpose of this study was to assess the combined effect of frailty and delirium on in-hospital mortality and disposition at discharge among older adults hospitalized with ADHF. Methods: We conducted a retrospective observational study using Nationwide Inpatient Sample data from the Agency for Healthcare Research and Quality from 2016 to 2018. Patients aged 65 years or older with a diagnosis of ADHF (both with preserved and reduced left ventricular ejection fraction) were included. For analysis, we conducted a multivariable logistic regression analysis to determine OR for in-hospital mortality or nonhome discharge from delirium and frailty. Results: A total of 3,577,433 weighted number of hospitalizations with ADHF were included. Delirium, moderate frailty risk, and high frailty risk increased the OR for in-hospital mortality (3.74; 95% CI: 3.70-3.78, 4.02; 95% CI: 3.96-4.09, and 8.63; 95% CI: 8.47-8.78, respectively) and nonhome discharge (4.21; 95% CI: 4.18-4.25, 2.95; 95% CI: 2.94-2.97, and 8.86; 95% CI: 8.78-8.94, respectively). When the combination of delirium and frailty was assessed, compared to those without delirium and with low frailty risk, the OR of mortality among those with delirium and high frailty risk was the highest at 12.18 (95% CI: 11.89-12.48). For nonhome discharge, the OR was the highest among those with delirium and high frailty risk at 14.01 (95% CI: 13.77-14.26). Conclusions: Frailty and delirium, independently and in combination, led to higher odds of in-hospital mortality and nonhome disposition at discharge among patients hospitalized with ADHF.

Palliative Pharmacotherapy for Cardiovascular Disease: A Scientific Statement From the American Heart Association.

Cardiovascular disease exacts a heavy toll on health and quality of life and is the leading cause of death among people ≥65 years of age. Although medical, surgical, and device therapies can certainly prolong a life span, disease progression from chronic to advanced to end stage is temporally unpredictable, uncertain, and marked by worsening symptoms that result in recurrent hospitalizations and excessive health care use. Compared with other serious illnesses, medication management that incorporates a palliative approach is underused among individuals with cardiovascular disease. This scientific statement describes palliative pharmacotherapy inclusive of cardiovascular drugs and essential palliative medicines that work synergistically to control symptoms and enhance quality of life. We also summarize and clarify available evidence on the utility of guideline-directed and evidence-based medical therapies in individuals with end-stage heart failure, pulmonary arterial hypertension, coronary heart disease, and other cardiomyopathies while providing clinical considerations for de-escalating or deprescribing. Shared decision-making and goal-oriented care are emphasized and considered quintessential to the iterative process of patient-centered medication management across the spectrum of cardiovascular disease.

Optimizing delirium care in the era of Age-Friendly Health System.

Delirium is a significant geriatric condition associated with adverse clinical and economic outcomes. The cause of delirium is usually multifactorial, and person-centered multicomponent approaches for proper delirium management are required. In 2017, the John A. Hartford Foundation and the Institute for Healthcare Improvement (IHI) launched a national initiative, Age-Friendly Health System (AFHS), promoting the use of a framework called 4Ms (what matters, medication, mentation, and mobility). The 4Ms framework's primary goal is to provide comprehensive and practical person-centered care for older adults and it aligns with the core concepts of optimal delirium management. In this special article, we demonstrate how a traditional delirium prevention and management model can be assessed from the perspective of AFHS. An example is the crosswalk with the Hospital Elder Life Program (HELP) Core Interventions and the 4MS, which demonstrates alignment in delirium management. We also introduce useful tools to create an AFHS environment in delirium management. Although much has been written about delirium management, there is a need to identify the critical steps in advancing the overall delirium care in the context of the AFHS. In this article, we suggest future directions, including the need for more prospective and comprehensive research to assess the impact of AFHS on delirium care, the need for more innovative and sustainable education platforms, fundamental changes in the healthcare payment system for proper adoption of AFHS in any healthcare setting, and application of AFHS in the community for continuity of care for older adults with delirium.

TAVR in Older Adults: Moving Toward a Comprehensive Geriatric Assessment and Away From Chronological Age: JACC Family Series.

Calcific aortic stenosis can be considered a model for geriatric cardiovascular conditions due to a confluence of factors. The remarkable technological development of transcatheter aortic valve replacement was studied initially on older adult populations with prohibitive or high-risk for surgical valve replacement. Through these trials, the cardiovascular community has recognized that stratification of these chronologically older adults can be improved incrementally by invoking the concept of frailty and other geriatric risks. Given the complexity of the aging process, stratification by chronological age should only be the initial step but is no longer sufficient to optimally quantify cardiovascular and noncardiovascular risk. In this review, we employ a geriatric cardiology lens to focus on the diagnosis and the comprehensive management of aortic stenosis in older adults to enhance shared decision-making with patients and their families and optimize patient-centered outcomes. Finally, we highlight knowledge gaps that are critical for future areas of study.

Real-world safety of neurohormonal antagonist initiation among older adults following a heart failure hospitalization.

AIMS: To optimize guideline-directed medical therapy for heart failure, patients may require the initiation of multiple neurohormonal antagonists (NHAs) during and following hospitalization. The safety of this approach for older adults is not well established. METHODS AND RESULTS: We conducted an observational cohort study of 207 223 Medicare beneficiaries discharged home following a hospitalization for heart failure with reduced ejection fraction (HFrEF) (2008-2015). We performed Cox proportional hazards regression to examine the association between the count of NHAs initiated within 90 days of hospital discharge (as a time-varying exposure) and all-cause mortality, all-cause rehospitalization, and fall-related adverse events over the 90 day period following hospitalization. We calculated inverse probability-weighted hazard ratios (IPW-HRs) with 95% confidence intervals (CIs) comparing initiation of 1, 2, or 3 NHAs vs. 0. The IPW-HRs for mortality were 0.80 [95% CI (0.78-0.83)] for 1 NHA, 0.70 [95% CI (0.66-0.75)] for 2, and 0.94 [95% CI (0.83-1.06)] for 3. The IPW-HRs for readmission were 0.95 [95% CI (0.93-0.96)] for 1 NHA, 0.89 [95% CI (0.86-0.91)] for 2, and 0.96 [95% CI (0.90-1.02)] for 3. The IPW-HRs for fall-related adverse events were 1.13 [95% CI (1.10-1.15)] for 1 NHA, 1.25 [95% CI (1.21-1.30)] for 2, and 1.64 [95% CI (1.54-1.76)] for 3. CONCLUSIONS: Initiating 1-2 NHAs among older adults within 90 days of HFrEF hospitalization was associated with lower mortality and lower readmission. However, initiating 3 NHAs was not associated with reduced mortality or readmission and was associated with a significant risk for fall-related adverse events.

The association of intensive blood pressure treatment and non-fatal cardiovascular or serious adverse events in older adults with mortality: mediation analysis in SPRINT.

AIMS: Randomized clinical trials of hypertension treatment intensity evaluate the effects on incident major adverse cardiovascular events (MACEs) and serious adverse events (SAEs). Occurrences after a non-fatal index event have not been rigorously evaluated. The aim of this study was to evaluate the association of intensive (<120 mmHg) to standard (<140 mmHg) blood pressure (BP) treatment with mortality mediated through a non-fatal MACE or non-fatal SAE in 9361 participants in the Systolic Blood Pressure Intervention Trial. METHODS AND RESULTS: Logistic regression and causal mediation modelling to obtain direct and mediated effects of intensive BP treatment. Primary outcome was all-cause mortality (ACM). Secondary outcomes were cardiovascular (CVM) and non-CV mortality (non-CVM). The direct effect of intensive treatment was a lowering of ACM [odds ratio (OR) 0.75, 95% confidence interval (CI): 0.60-0.94]. The MACE-mediated effect substantially attenuated (OR 0.96, 95% CI: 0.92-0.99) ACM, while the SAE-mediated effect was associated with increased (OR 1.03, 95% CI: 1.01-1.05) ACM. Similar patterns were noted for intensive BP treatment on CVM and non-CVM. We also noted that SAE incidence was 3.9-fold higher than MACE incidence (13.7 vs. 3.5%), and there were a total of 365 (3.9%) ACM cases, with non-CVM being 2.6-fold higher than CVM [2.81% (263/9361) vs. 1.09% (102/9361)]. The SAE to MACE and non-CVM to CVM preponderance was found across all age groups, with the ≥80-year age group having the highest differences. CONCLUSION: The current analytic techniques demonstrated that intensive BP treatment was associated with an attenuated mortality benefit when it was MACE-mediated and possibly harmful when it was SAE-mediated. Current cardiovascular trial reporting of treatment effects does not allow expansion of the lens to focus on important occurrences after the index event.

The benefit of intensive (<120 mmHg) blood pressure (BP) treatment, reduction in all-cause mortality (ACM), was attenuated when mediated through non-fatal major adverse cardiovascular events. This was driven by cardiovascular mortality (CVM). The harm of intensive BP treatment, increase in ACM, was amplified when mediated through serious adverse events. This was driven by non-CVM. Current reporting of treatment effects in cardiovascular trials does not allow for expansion of the lens to focus on important occurrences after the index event.

Life's Essential 8: Optimizing Health in Older Adults.

The population worldwide is getting older as a result of advances in public health, medicine, and technology. Older individuals are living longer with a higher prevalence of subclinical and clinical cardiovascular disease (CVD). In 2010, the American Heart Association introduced a list of key prevention targets, known as "Life's Simple 7" to increase CVD-free survival, longevity, and quality of life. In 2022, sleep health was added to expand the recommendations to "Life's Essential 8" (eat better, be more active, stop smoking, get adequate sleep, manage weight, manage cholesterol, manage blood pressure, and manage diabetes). These prevention targets are intended to apply regardless of chronologic age. During this same time, the understanding of aging biology and goals of care for older adults further enhanced the relevance of prevention across the range of functions. From a biological perspective, aging is a complex cellular process characterized by genomic instability, telomere attrition, loss of proteostasis, inflammation, deregulated nutrient-sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, and altered intercellular communication. These aging hallmarks are triggered by and enhanced by traditional CVD risk factors leading to geriatric syndromes (eg, frailty, sarcopenia, functional limitation, and cognitive impairment) which complicate efforts toward prevention. Therefore, we review Life's Essential 8 through the lens of aging biology, geroscience, and geriatric precepts to guide clinicians taking care of older adults.

Medication Complexity Among Older Adults with HF: How Can We Assess Better?

Medical management of heart failure (HF) has evolved and has achieved significant survival benefits, resulting in highly complex medication regimens. Complex medication regimens create challenges for older adults, including nonadherence and increased adverse drug events, especially associated with cognitive impairment, physical limitations, or lack of social support. However, the association between medication complexity and patients' health outcomes among older adults with HF is unclear. The purpose of this review is to address how the complexity of HF medications has been assessed in the literature and what clinical outcomes are associated with medication regimen complexity in HF. Further, we aimed to explore how older adults were represented in those studies. The Medication Regimen Complexity Index was the most commonly used tool for assessment of medication regimen complexity. Rehospitalization was most frequently assessed as the clinical outcome, and other studies used medication adherence, quality of life, healthcare utilization, healthcare cost, or side effect. However, the studies showed inconsistent results in the association between the medication regimen complexity and clinical outcomes. We also identified an extremely small number of studies that focused on older adults. Notably, current medication regimen complexity tools did not consider a complicated clinical condition of an older adult with multimorbidity, therapeutic competition, drug interactions, or altered tolerance to the usual dose strength of the medications. Furthermore, the outcomes that studies assessed were rarely comprehensive or patient centered. More studies are required to fill the knowledge gap identifying more comprehensive and accurate medication regimen complexity tools and more patient-centered outcome assessment.

Geriatric Cardiology: Coming of Age.

Older adults with cardiovascular disease (CVD) contend with deficits across multiple domains of health due to age-related physiological changes and the impact of CVD. Multimorbidity, polypharmacy, cognitive changes, and diminished functional capacity, along with changes in the social environment, result in complexity that makes provision of CVD care to older adults challenging. In this review, we first describe the history of geriatric cardiology, an orientation that acknowledges the unique needs of older adults with CVD. Then, we introduce 5 essential principles for meeting the needs of older adults with CVD: 1) recognize and consider the potential impact of multicomplexity; 2) evaluate and integrate constructs of cognition into decision-making; 3) evaluate and integrate physical function into decision-making; 4) incorporate social environmental factors into management decisions; and 5) elicit patient priorities and health goals and align with care plan. Finally, we review future steps to maximize care provision to this growing population.

Serum Concentrations of Losartan Metabolites Correlate With Improved Physical Function in a Pilot Study of Prefrail Older Adults.

Losartan is an oral antihypertensive agent that is rapidly metabolized to EXP3174 (angiotensin-subtype-1-receptor blocker) and EXP3179 (peroxisome proliferator-activated receptor gamma [PPARγ] agonist), which was shown in animal studies to reduce inflammation, enhance mitochondrial energetics, and improve muscle repair and physical performance. We conducted an exploratory pilot study evaluating losartan treatment in prefrail older adults (age 70-90 years, N = 25). Participants were randomized to control (placebo) or treatment (daily oral losartan beginning at 25 mg per day and increasing every 8 weeks) for a total of 6 months. Fatigue, hyperkalemia, and hypotension were the most observed side effects of losartan treatment. Participants in the losartan group had an estimated 89% lower odds of frailty (95% confidence interval [CI]: 18% to 99% lower odds, p = .03), with a 0.3-point lower frailty score than the placebo group (95% CI: 0.01-0.5 lower odds, p = .04). Frailty score was also negatively associated with serum losartan and EXP3179 concentrations. For every one standard deviation increase in EXP3179 (ie, 0.0011 ng/µL, based on sample values above detection limit) and EXP3174 (ie, 0.27 ng/µL, based on sample values above detection limit), there was a 0.0035 N (95% CI: 0.0019-0.0051, p < .001) and a 0.0027 N (95% CI: 0.00054-0.0043, p = .007) increase in average knee strength, respectively.

Delirium in Frail Older Adults.

Delirium and frailty are prevalent geriatric syndromes and important public health issues among older adults. The prevalence of delirium among hospitalized older adults ranges from 15% to 75%, while that of frailty ranges from 12% to 24%. The exact pathophysiology of these two conditions has not been clearly identified, although several hypotheses have been proposed. However, these conditions are considered to be multifactorial in etiology and are associated with inflammation related to aging, alterations in vascular systems, genetics, and nutritional deficiency. Furthermore, clinically, they are significantly associated with frailty, which increases the risk of delirium by almost two- to three-fold among hospitalized older adults. With their multifactorial etiology and unknown pathophysiology, current evidence supports more practical multicomponent patient-centered approaches to prevent and manage delirium with frailty among hospitalized older adults. These comprehensive and organized bundled approaches can identify high-risk patients with frailty and more effectively manage their delirium.
