Hearing Loss, Hearing Aids, and Functional Status.

Importance: Hearing loss may contribute to poor functional status via cognitive impairment and social isolation. Hearing aids may play a protective role by attenuating these downstream outcomes. However, population-based evidence is lacking. Objective: To examine the association of hearing loss and hearing aids with functional status. Design, Setting, and Participants: This cross-sectional (2016-2017) and longitudinal (2016-2022) analysis of data from the Atherosclerosis Risk in Communities cohort study included older, community-dwelling adults with complete data. Data were analyzed from June to December 2023. Exposures: The better-hearing ear's pure tone average (BPTA) at speech frequencies (0.5-4 kHz) was modeled categorically (no [BPTA ≤25 dB], mild [26-40 dB], and moderate or greater hearing loss [>40 dB]). Hearing aid use was self-reported. Main Outcomes and Measures: Difficulties in activities of daily living (ADLs; eg, dressing and eating), instrumental activities of daily living (IADLS; eg, household chores and meal preparation), and heavier tasks (eg, walking a quarter of a mile) were self-reported at visit 6. The ability to perform usual activities, walk a half mile, walk up and down stairs, and do heavy housework without help were collected in follow-up surveys. Linear and logistic regression models were used that were adjusted for sociodemographic and health covariates. Results: Among 3142 participants (mean [SD] age, 79.3 [4.6] years; 1828 women [58.2%]), 1013 (32.2%) had no hearing loss, 1220 (38.8%) had mild hearing loss, and 909 (29.0%) had moderate or greater hearing loss. Moderate or greater hearing loss was cross-sectionally associated with difficulty in 1 or more ADLs (odds ratio [OR], 1.27; 95% CI, 1.02-1.58), IADLs (OR, 1.34; 95% CI, 1.05-1.71), and heavier tasks (OR, 1.29; 95% CI, 1.04-1.62) compared with no hearing loss. Over time (mean [SD] follow-up, 1.9 [1.8] years), moderate or greater hearing loss was associated with a faster decline in the number of activities participants were able to do (ß = -0.07 per year; 95% CI, -0.09 to -0.06) and greater odds of reporting inability to do 1 or more of the 4 activities (OR, 1.14; 95% CI, 1.05-1.24). Hearing aid users and nonusers did not differ. Conclusions and Relevance: The results of this study suggest that moderate or greater hearing loss was associated with functional difficulties and may contribute to a faster decline in function longitudinally independent of sociodemographic and health covariates. Hearing aids did not change the association among those with hearing loss.

Hearing Loss, Hearing Aids, and Satisfaction With Health Care in the National Health Interview Survey.

OBJECTIVE: Hearing loss may negatively impact satisfaction with health care via patient-provider communication barriers and may be amenable to hearing care treatment. STUDY DESIGN: Cross-sectional. SETTING: National Health Interview Survey, a nationally representative survey of noninstitutionalized US residents, 2013 to 2018 pooled cycles. METHODS: Participants described satisfaction with health care in the past year, categorized as optimal (very satisfied) versus suboptimal (satisfied, dissatisfied, very dissatisfied) satisfaction. Self-report hearing without hearing aids (excellent, good, a little trouble, moderate trouble, a lot of trouble) and hearing aid use (yes, no) were collected. Weighted Poisson regression models adjusted for sociodemographic and health covariates were used to estimate prevalence rate ratios (PRRs) of satisfaction with care by hearing loss and hearing aid use. RESULTS: Among 137,216 participants (mean age 50.9 years, 56% female, 12% black), representing 77.2 million Americans in the weighted model, 19% reported trouble hearing. Those with good (PRR = 1.20, 95% confidence interval [CI]: 1.18-1.23), a little trouble (PRR = 1.27, 95% CI, 1.23-1.31), moderate trouble (PRR = 1.29, 95% CI, 1.24-1.35), and a lot of trouble hearing (PRR = 1.26, 95% CI, 1.18-1.33) had a higher prevalence rate of suboptimal satisfaction with care relative to those with excellent hearing. Among all participants with trouble hearing, hearing aid users had a 17% decrease in the prevalence rate of suboptimal satisfaction with care (PRR = 0.83, 95% CI, 0.78-0.88) compared to nonusers. CONCLUSION: Hearing loss decreases patient satisfaction with health care, which is tied to Medicare hospital reimbursement models. Hearing aid use may improve patient-provider communication and patient satisfaction, although prospective studies are warranted to truly establish their protective effect.

Multimorbidity is associated with lower total 24-hour movement activity among US adults.

Objective: Having chronic conditions may result in reduced physical and cognitive function but less is known about multimorbidity with daily movement. We examined the association of multimorbidity and device-measured total daily movement in a nationally representative sample of US adults aged ≥ 30 years from the 2011-2014 National Health and Nutrition Examination Surveys. Methods: Any multimorbidity (≥2 conditions) and complex multimorbidity (≥3 conditions across ≥ 3 body systems) were quantified using 16 chronic conditions via self-report and/or clinical thresholds. Total movement over 24-hours (Monitor-Independent Movement Summary units [MIMS-units]) was measured using a wrist-worn device (ActiGraph GT3X). Multivariable linear regression examined the association of 1) each chronic condition, 2) number of conditions, 3) any multimorbidity, and 4) complex multimorbidity with total movement. Covariates included age, gender, race/ethnicity, educational attainment, and smoking status. Results: Among US adults (N = 7304, mean age: 53.2 ± 0.34 years, 53.2% female, 69.4% Non-Hispanic White), 62.2% had any multimorbidity with 34.2% having complex multimorbidity. After adjustment, a higher number of chronic conditions was associated with incrementally lower total movement (ß MIMS-units [95% CI] compared to those with no chronic conditions; one: -419 [-772, -66], two: -605 [-933, -278], three: -1201 [-1506, -895], four: -1908 [-2351, -1465], 5+: -2972 [-3384, -2560]). Complex multimorbidity presence was associated with -1709 (95% CI: -2062, -1357) and -1269 (-1620, -918) lower total movement compared to those without multimorbidity and multimorbidity but not complex, respectively. Conclusions: Multimorbidity was associated with lower 24-h movement among US adults and may be helpful for identifying adults at risk for low movement.

Prediction of adverse cardiac outcomes in high-risk Mexican patients with chest pain in the emergency department / Desenlaces adversos cardiovasculares en pacientes mexicanos de alto riesgo con dolor torácico en el servicio de urgencias

Abstract Objective: The aim of the study was to compare the discriminative power and accuracy for prediction of MACE of five commonly used scoring tools in Mexican patients with chest pain who present to the ED. Methods: A single-center, prospective, observational, and comparative study of patients admitted to the ED with chest pain as the chief complaint. Five chest pain scoring systems were calculated. The primary endpoint was the composite of cardiovascular death, myocardial infarction, coronary intervention, coronary artery bypass grafting, or readmission for cardiovascular causes within 30 days. Results: A total of 168 patients were studied. The score which provided the highest area under the curve of 0.76 (95% CI: 0.70-0.85) was history, ECG, age, risk factors, and troponin (HEART) score. In addition, the integrated discrimination index for the HEART score was 6% higher when compared to the other four scores. Conclusions: The HEART score provided the best classification tool for identifying those patients at highest risk for MACE, either alone or by adding their results to other classification scores, even in a comorbid population.

Resumen Objetivo: Comparar el poder discriminativo y precisión diagnóstica de Eventos Cardiovasculares Mayores (ECVM) de cinco escalas de clasificación de dolor torácico de uso común en pacientes mexicanos con dolor torácico que acuden al servicio de urgencias. Métodos: Estudio prospectivo, observacional y comparativo que incluyó a pacientes ingresados en urgencias que presentaban dolor torácico como síntoma cardinal. Se calcularon cinco escalas de puntuación de dolor torácico. El desenlance principal fue el compuesto de muerte cardiovascular, infarto de miocardio, intervención coronaria, injerto de derivación de arteria coronaria o reingreso por causas cardiovasculares dentro de los 30 días. Resultados: Se estudió un total de 168 pacientes. La escala de puntuación que proporcionó el área bajo la curva más alta de 0.76 (IC de 95%: 0.70-0.85) fue la escala de historia clínica, ECG, edad, factores de riesgo y troponina (HEART, por sus siglas en inglés). Además, el indice de discriminación efectiva para la puntuación HEART fue un 6% más alto en comparación con las otras cuatro escalas de puntuación. Conclusiones: La escala de HEART proporcionó la mejor herramienta de clasificación para idenfiticar a los pacientes con mayor riesgo de ECVM, ya sea solo a agregando sus resultados a otros puntajes de clasificación, incluso en una población comórbida.

Demographic description and outcomes of a metropolitan network for myocardial infarction treatment / Descripción demográfica y desenlaces de una red metropolitana de atención para el infarto agudo de miocardio

Abstract Objective: The objective of the study was to describe the myocardial infarction treatment network and compare in-hospital mortality in patients undergoing either primary angioplasty or pharmacoinvasive strategy in Mexico City and a broad metropolitan area. Methods: Cohort study including patients with ST-elevation myocardial infarction. We recorded demographic and clinical data, laboratory tests and in-hospital mortality in patients that underwent primary angioplasty and pharmacoinvasive strategy. Kaplan-Meier analysis was used to assess mortality and Cox-regression assessed mortality risk factors. Results: Three hundred forty patients from a network of 60 hospitals and 9 states were analyzed. Of the total population, 166 were treated with pharmacoinvasive strategy and 174 with primary angioplasty. Door to thrombolytic time was 54 min and door to wire crossing time was 72.5 min; no differences in total ischemia time were demonstrated. No differences for in-hospital mortality (6.3% vs. 5.4%, p = 0.49) were found when comparing pharmacoinvasive and primary angioplasty groups. The main predictors for in-hospital mortality were: glucose > 180 mg/dl (HR 3.73), total ischemia time > 420 min (HR 3.18), heart rate > 90 bpm (HR 5.46), Killip and Kimball > II (HR 11.03), and left ventricle ejection fraction < 40% (HR 3.21). Conclusions: This myocardial infarction network covers a large area and constitutes one of the biggest in the world. There were no differences regarding in-hospital mortality between pharmacoinvasive strategy and primary angioplasty. Pharmacoinvasive strategy is an effective and safe option for prompt reperfusion in Mexico.

Métodos: Estudio de cohorte que incluyó pacientes con infarto agudo de miocardio con elevación del segmento ST. Se recabaron datos demográficos y clínicos, así como estudios de laboratorio y mortalidad intrahospitalaria en los pacientes que fueron tratados con angioplastía coronaria o estrategia farmacoinvasiva. Se realizó un análisis de Kaplan-Meier para describir la mortalidad y un modelo de regresión de Cox para evaluar los factores asociados a mortalidad. Resultados: Se analizaron 340 pacientes provenientes de una red compuesta por 60 hospitales. Del total de la población, 166 fueron tratados con estrategia farmacoinvasiva y 174 con angioplastía primaria. El tiempo puerta-aguja fue 54 min. y el tiempo puerta-dispositivo de 72.5 min.; no se encontraron diferencias en el tiempo total de isquemia. Además, no existieron diferencias en la mortalidad intrahospitalaria (6.3% vs. 5.4%, p = 0.49) al comparar la estrategia farmacoinvasiva y la angioplastía primaria. Los principales predictores de mortalidad intrahospitalaria fueron: glucosa > 180 mg/dl (HR 3.73), tiempo total de isquemia > 420 min. (HR 3.18), frecuencia cardiaca > 90 lpm (HR 5.46), Killip and Kimball > II (HR 11.03) y fracción de eyección < 40% (HR 3.21). Conclusiones: En esta red de atención al infarto agudo de miocardio no se encontraron diferencias en la mortalidad intrahospitalaria entre la estrategia farmacoinvasiva y la angioplastia primaria. La estrategia farmacoinvasiva puede ser una alternativa efectiva y segura para lograr reperfusión adecuada en México.

The Upcoming Epidemic of Heart Failure in South Asia.

Currently, South Asia accounts for a quarter of the world population, yet it already claims ≈60% of the global burden of heart disease. Besides the epidemics of type 2 diabetes mellitus and coronary heart disease already faced by South Asian countries, recent studies suggest that South Asians may also be at an increased risk of heart failure (HF), and that it presents at earlier ages than in most other racial/ethnic groups. Although a frequently underrecognized threat, an eventual HF epidemic in the densely populated South Asian nations could have dramatic health, social and economic consequences, and urgent interventions are needed to flatten the curve of HF in South Asia. In this review, we discuss recent studies portraying these trends, and describe the mechanisms that may explain an increased risk of premature HF in South Asians compared with other groups, with a special focus on highly relevant features in South Asian populations including premature coronary heart disease, early type 2 diabetes mellitus, ubiquitous abdominal obesity, exposure to the world's highest levels of air pollution, highly prevalent pretransition forms of HF such as rheumatic heart disease, and underdevelopment of healthcare systems. Other rising lifestyle-related risk factors such as use of tobacco products, hypertension, and general obesity are also discussed. We evaluate the prognosis of HF in South Asian countries and the implications of an anticipated HF epidemic. Finally, we discuss proposed interventions aimed at curbing these adverse trends, management approaches that can improve the prognosis of prevalent HF in South Asian countries, and research gaps in this important field.

Evaluation of pharmacoinvasive strategy versus percutaneous coronary intervention in patients with acute myocardial infarction with ST-segment elevation at the National Institute of Cardiology (PHASE-MX) / Evaluación de la estrategia farmacoinvasiva versus angioplastia coronaria transluminal percutánea primaria en pacientes con infarto agudo de miocardio con elevación del segmento ST en el Instituto Nacional de Cardiología (PHASE-MX)

Abstract Objective: The objective of PHASE-MX registry is to validate the efficacy and safety of the pharmacoinvasive strategy in comparison with percutaneous coronary intervention (PCI) in patients with acute myocardial infarction with ST segment elevation (STEMI) in a metropolitan region of Mexico. The primary outcome will consist of the composite of cardiovascular death, re-infarction, stroke and cardiogenic shock. Methods: The PHASE-MX registry will include a prospective cohort of patients with STEMI who received reperfusion treatment (mechanical of pharmacological) in the first 12 h after the onset of symptoms. The registry is designed to compare the efficacy and safety of primary PCI and pharmacoinvasive strategy. The simple size was calculated in 344 patients divided into two groups, with an estimated loss rate of 10%. Patients included in the PHASE-MX cohort will be followed for up to one year. Conclusion: In Mexico, only 5 out of 10 patients with STEMI have access to reperfusion therapy. Pharmacoinvasive strategy is takes advantage of the accessibility of fibrinolysis and the effectiveness of PCI. The present research protocol aims to provide information that serves as a link between information derived from controlled clinical trials and records derived from real world experience.

Resumen Objetivo: El objetivo del registro PHASE-MX es validar la eficacia y seguridad de la estrategia farmacoinvasiva en comparación con la angioplastia coronaria transluminal percutánea primaria (ACTPp) en pacientes con infarto agudo de miocardio con elevación del segmento ST (IAMCEST) en una región metropolitana de México. El desenlace primario es el compuesto de muerte cardiovascular, reinfarto, accidente vascular cerebral y choque cardiogénico. Métodos: El registro PHASE-MX es una cohorte prospectiva de pacientes con IAMCEST que recibieron tratamiento de reperfusión (mecánico o farmacológico) en las primeras 12 horas desde el inicio de los síntomas, atendidos en el Instituto Nacional de Cardiología Ignacio Chávez. El análisis estadístico se basa en la no inferioridad de la estrategia farmacoinvasiva en comparación con la ACTPp. Se calcula un tamaño de muestra de 344 pacientes divididos en dos grupos (angioplastia primaria y estrategia farmacoinvasiva), considerada una tasa de pérdidas de 10%. Los pacientes incluidos en la cohorte PHASE-MX se seguirán durante un año. Discusión: En México, sólo 5 de cada 10 pacientes con IAMCEST tienen acceso al tratamiento de reperfusión. La estrategia farmacoinvasiva aprovecha la accesibilidad de la fibrinólisis y la efectividad de la ACTPp, por lo que podría resultar el método de elección en el tratamiento del IAMCEST en la mayoría de los casos. El presente protocolo de investigación pretende aportar información que sirva como enlace entre la información derivada de los estudios clínicos controlados y los registros derivados de la experiencia del mundo real.

Insuficiencia cardíaca con fracción de expulsión preservada: el lado oscuro de una vieja enfermedad / Heart failure with preserved ejection fraction: the dark side of an old disease

Resumen La insuficiencia cardíaca (IC) es un problema de salud pública global con más de 37 millones de individuos afectados en el mundo. La insuficiencia cardíaca con fracción de expulsión preservada (ICFEp) representa una categoría cada vez más frecuente en la práctica clínica, constituye hasta el 60% de los casos y presenta diferencias importantes en el diagnóstico y tratamiento en comparación con la insuficiencia cardíaca y la fracción de expulsión reducida. Esta revisión de ICFEp expone la epidemiología, delimita los principales factores de riesgo y mecanismos fisiopatológicos, identifica las características clínicas/paraclínicas y los criterios diagnósticos, y finaliza con un llamado para realizar investigación en este país.

Abstract Heart failure is a global public health problem, with more than 37 million patients living with heart failure around the world. Heart failure with preserved ejection fraction is an increasingly common category (approximately 60% of the cases) and shows remarkable differences in diagnosis and treatment when compared with heart failure with reduced ejection fraction. The current review covers epidemiology, risk factors, pathophysiologic mechanisms, clinical and paraclinical characteristics and diagnostic criteria of heart failure with preserved ejection fraction and concludes with a plea for original research in our country.

Association Between Adiposity and Perceived Physical Fatigability in Mid- to Late Life.

OBJECTIVE: This study aimed to compare and contrast the associations between measures of adiposity and fat distribution and perceived fatigability among well-functioning individuals in mid- to late life. METHODS: In 1,054 adults (70.4 ± 12.4 years, 52% female), adiposity was measured as BMI, percent fat (dual-energy x-ray absorptiometry), waist and hip circumferences, and waist to height ratio. In a subset of 383 participants, visceral fat was measured. Perceived fatigability was evaluated after a 5-minute treadmill walk (1.5 mph) using the Borg rating of perceived exertion (range, 6-20). Associations between adiposity measures and perceived fatigability were assessed using regression models adjusting for age, sex, race, smoking, and comorbidities. RESULTS: All adiposity measures, except subcutaneous fat, were positively associated with perceived fatigability after adjustment (P < 0.05 for all). Standardized coefficients indicated that BMI, hip circumference, and visceral fat had the strongest associations with fatigability. Associations between BMI and fatigability were present only among those above the threshold for overweight and strongest in those aged ≥ 65 years. Moreover, BMI was associated with fatigability only among participants with higher waist circumference. CONCLUSIONS: Measures of adiposity, particularly central adiposity, are strongly associated with fatigability, suggesting that weight management may be an effective target for curbing fatigability and maintaining quality of life with aging.

Contrasting characteristics of daily physical activity in older adults by cancer history.

BACKGROUND: Using objectively collected physical activity (PA) data from the Baltimore Longitudinal Study of Aging, the authors tested whether patterns of daily activity and sedentary time differed by cancer survivorship in older adults. METHODS: In total, 659 participants (mean age ± standard deviation, 71 ± 10 years; 51% women) who had self-reported information on cancer history were instructed to wear an accelerometer for 7 consecutive days. Accelerometer data were summarized into: 1) PA volume and 2) activity fragmentation (interrupted activity), expressed as both continuous and as dichotomized (low and high) variables. Participants were categorized into 4 groups by cross-classification of dichotomous PA volume and fragmentation. Multiple regression models were used to estimate differences in PA patterns by cancer history. RESULTS: Cancer survivors averaged 0.12 fewer log-transformed activity counts per day (standard error, 0.05; P = .02) than individuals who reported no history of cancer after adjusting for demographics, behavioral factors, and comorbidities. Although fragmentation did not differ by cancer survivorship in the continuous model (P = .13), cancer survivorship was associated with 77% greater odds (odds ratio, 1.77; 95% confidence interval, 1.11-2.82) of having high (vs low) fragmentation and 94% greater odds (odds ratio, 1.94; 95% confidence interval, 1.13-3.33) of having combined low PA/high fragmentation (vs high PA/low fragmentation) relative to those with no cancer history. CONCLUSIONS: The current findings suggest that cancer survivors engage in lower total daily PA and that they perform this activity in a more fragmented manner compared with adults without a history of cancer. These results may reflect the onset and progression of a low-activity phenotype that is more vulnerable to heightened levels of fatigue and functional decline with aging.
