Heart Failure In Older Adults Research Articles

Clustering of Cardiovascular Risk Factors and Heart Failure in Older Adults from the Brazilian Far North.

Given the aging global population, identifying heart failure (HF) phenotypes has become crucial, as distinct disease characteristics can influence treatment and prognosis in older adults. This study aimed to analyze the association between clustering of cardiovascular risk factors and HF in older adults. A cross-sectional epidemiological study was conducted with 1322 older adults (55% women, mean age 70.4) seen in primary health care. Diagnosis of HF was performed by a cardiologist based on diagnostic tests and medical history. Cardiovascular risk factors included hypertension, diabetes, hypercholesterolemia, and smoking. Using logistic regression, potential associations were tested. Individual risk factor analysis showed that older adults with hypertension, diabetes, or hypercholesterolemia had up to 7.6 times higher odds to have HF. The cluster where older adults had only one risk factor instead of none increased the odds of HF by 53.0%. Additionally, the odds of older patients having HF ranged from 3.59 times for the two-risk factor cluster to 20.61 times for the simultaneous presence of all four factors. The analysis of clusters substantially increasing HF risk in older adults revealed the importance of individualizing subgroups with distinct HF pathophysiologies. The clinical significance of these clusters can be beneficial in guiding a more personalized therapeutic approach.

Metabolomic Association and Risk Prediction With Heart Failure in Older Adults.

Older adults have markedly increased risks of heart failure (HF), specifically HF with preserved ejection fraction (HFpEF). Identifying novel biomarkers can help in understanding HF pathogenesis and improve at-risk population identification. This study aimed to identify metabolites associated with incident HF, HFpEF, and HF with reduced ejection fraction and examine risk prediction in older adults. Untargeted metabolomic profiling was performed in Black and White adults from the ARIC study (Atherosclerosis Risk in Communities) visit 5 (n=3719; mean age, 75 years). We applied Cox regressions to identify metabolites associated with incident HF and its subtypes. The metabolite risk score (MRS) was constructed and examined for associations with HF, echocardiographic measures, and HF risk prediction. Independent samples from visit 3 (n=1929; mean age, 58 years) were used for replication. Sixty metabolites (hazard ratios range, 0.79-1.49; false discovery rate, <0.05) were associated with incident HF after adjusting for clinical risk factors, eGFR, and NT-proBNP (N-terminal pro-B-type natriuretic peptide). Mannonate, a hydroxy acid, was replicated (hazard ratio, 1.36 [95% CI, 1.19-1.56]) with full adjustments. MRS was associated with an 80% increased risk of HF per SD increment, and the highest MRS quartile had 8.7× the risk of developing HFpEF than the lowest quartile. High MRS was also associated with unfavorable values of cardiac structure and function. Adding MRS over clinical risk factors and NT-proBNP improved 5-year HF risk prediction C statistics from 0.817 to 0.850 (∆C, 0.033 [95% CI, 0.017-0.047]). The association between MRS and incident HF was replicated after accounting for clinical risk factors (P<0.05). Novel metabolites associated with HF risk were identified, elucidating disease pathways, specifically HFpEF. An MRS was associated with HF risk and improved 5-year risk prediction in older adults, which may assist at at-risk population identification.

Considerations Regarding Management of Heart Failure in Older Adults.

Understanding noncardiovascular comorbidities and geriatric syndromes in elderly patients with heart failure (HF) is important as the average age of the population increases. Healthcare professionals need to consider these complex dynamics when managing older adults with HF, especially those older than 80. A number of small studies have described associations between HF and major geriatric domains. With information on patients' cognitive, functional decline, and ability to adhere to therapy, physicians can plan for individualized treatment goals and recommendations for these patients.

Iron Deficiency and Incident Heart Failure in Older Community-Dwelling Individuals.

Among persons with prevalent heart failure (HF), iron deficiency has been linked to HF admissions, and intravenous iron replacement improves HF outcomes. Recent studies in persons with chronic kidney disease (CKD) demonstrate that iron deficiency is associated with incident HF. This study aimed to determine the relationship of iron status with incident HF in community-dwelling older adults irrespective of their kidney function. In this case-cohort study, 1,006 Cardiovascular Health Study participants (785 from the random sub-cohort [including 193 HF cases] and 221 additional HF cases [N=414 total HF cases]) aged ≥ 65years without HF (41% with CKD), we used weighted Cox models to evaluate associations of iron status with incident HF. Participants were categorized based on quartiles of transferrin saturation and ferritin as "iron replete" (27.3%), "functional iron deficiency" (7.7%), "iron deficiency" (11.8%), "mixed iron deficiency" (5.6%), "high iron" (9.3%) and "non-classified" (38.1%), consistent with prior studies. Compared to older persons who were iron replete, those with iron deficiency were at higher risk of incident HF (HR 1.47; 1.02-2.11) in models adjusting for demographics, HF risk factors, and estimated glomerular filtration rate. Other iron categories did not associate with incident HF. The relationship of iron deficiency with incident HF did not differ by CKD status (interaction P value 0.2). Among community-dwelling elders, iron deficiency is independently associated with incident HF, an association that was similar irrespective of CKD status. Our findings support conduct of clinical trials of iron replacement for prevention of HF in older adults with iron deficiency.

The burden of frailty in heart failure: Prevalence, impacts on clinical outcomes and the role of heart failure medications.

Frailty often coexists with heart failure (HF), which significantly aggravates the clinical outcomes of older adults. However, studies investigating the interplay between frailty and HF in older adults are scarce. We aimed to assess the prevalence of frailty using the cumulative deficit approach and evaluate the impacts of frailty on health utilization, use of HF-related medications and adverse clinical outcomes (all-cause mortality, all-cause readmissions and HF readmissions) among older HF patients. A total of 38843 newly admitted HF patients were identified from Taiwan's National Health Insurance Research Database and categorized into three frailty subgroups (fit, mild frailty and severe frailty) based on the multimorbidity frailty index. Cox regression models and Fine and Gray subdistribution hazard models were used to estimate the impacts of frailty on clinical outcomes at 1 and 2years of follow-up. Generalized estimating equation models were further conducted to evaluate the associations between longitudinal and time-varying use of HF-related medications and clinical outcomes among distinct frailty subgroups. Of 38843 older HF patients (mean age 80.4±8.5years, 52.3% females) identified, 68.3% were categorized as frail (47.5% of mild frailty and 20.8% of severe frailty). The median number of readmissions (fit: 1 [inter-quartile range-IQR 2], mild frailty: 1 [IQR 2] and severe frailty: 2 [IQR 3]) increased with the severity of frailty. Only 27.3% of HF patients died of cardiovascular diseases regardless of their frailty status. Compared with the fit group, the severe frailty group was associated with increased risk of all-cause mortality (adjusted hazard ratio 1.16, 95% confidence interval [CI] 1.11-1.21), all-cause readmissions (subdistributional hazard ratio (sHR) 1.21, 95% CI 1.16-1.25) and HF-related readmissions (sHR 1.14, 95% CI 1.09-1.20) at 2years of follow-up. Those who used triple or more HF-related medications were at lower risk for all-cause readmissions (adjusted odds ratio [aOR] 0.49, 95% CI 0.44-0.54) and HF-related readmissions (aOR 0.42, 95% CI 0.37-0.47) at 2years of follow-up even in the severe frailty group. Frailty is highly prevalent and associated with increased risk of all-cause mortality, all-cause readmissions and HF readmissions among older HF patients. Those who were using triple or more HF-related medications were at lower risk of adverse clinical outcomes across distinct frailty subgroups. Further studies are needed to optimize the treatment strategies for older HF patients with distinct frailty status.

Abstract 12424: Left Atrial Strain and Incident Heart Failure in Older Adults

Introduction: The prevalence of heart failure (HF) is rising, particularly in older adults. Left atrial (LA) dysfunction is commonly seen in HF, but it is unclear if it predicts onset or contributes to its development. Hypothesis: LA strain reduction is associated with incident HF in the general elderly population, independent of other risk factors and even in the presence of normal LA volume. Aims: We aimed to investigate the association between reduced LA strain (LAε) and strain rate (LASR) and incident HF in older adults without history of HF or atrial fibrillation (AF), adjusting for HF risk factors and echocardiographic parameters. Methods: We examined 795 participants aged ≥55 from the Cardiovascular Abnormalities and Brain Lesions (CABL) study with no history of HF or AF. LAε pos , LASR pos , LASR early-neg , and LASR late-neg were assessed using speckle-tracking echocardiography for global, reservoir, conduit and pump function, respectively. Incident HF was detected through standardized interviews, in-person visits, active hospital surveillance of admission and discharge ICD-9 codes. LA strain's association with incident HF was assessed using a cause-specific hazards regression model, adjusting for HF risk factors, including incident AF. Results: Mean age was 70.9±9.2 years (297 men, 498 women). During a mean follow-up of 11.4 years, 215 participants (27.0%) developed new-onset HF; incident AF occurred in 98 (12.3%). Left ventricular ejection fraction and global longitudinal strain were not associated with new-onset HF (p=0.06 and p=0.23, respectively). All LA strain measures at baseline were significantly associated with new-onset HF (all p&lt;0.01). In multivariable analysis, only LASR late-neg (adjusted HR per SD decrease 2.31, 95% CI 1.12-4.43) remained independently associated with new-onset HF, after adjusting for LA volumes, left ventricular systolic function, and incident AF. LASR late-neg was especially associated with incident HF in participants with normal LA size (HR 8.64, CI 3.10-24.08). Conclusion: Reduced LA strain during atrial contraction is independently associated with new-onset HF in older adults. LA strain measurement may improve HF risk stratification in older adults, even in the presence of normal LA volume.

Elevated Plasma Levels of Ketone Bodies Are Associated With All-Cause Mortality and Incidence of Heart Failure in Older Adults: The CHS.

Background Chronic disease, such as heart failure, influences cellular metabolism and shapes circulating metabolites. The relationships between key energy metabolites and chronic diseases in aging are not well understood. This study aims to determine the relationship between main components of energy metabolism with all-cause mortality and incident heart failure. Methods and Results We analyzed the association between plasma metabolite levels with all-cause mortality and incident heart failure among US older adults in the CHS (Cardiovascular Health Study). We followed 1758 participants without heart failure at baseline with hazard ratios (HRs) of analyte levels and metabolic profiles characterized by high levels of ketone bodies for all-cause mortality and incident heart failure. Multivariable Cox analyses revealed a dose-response relationship of 50% increase in all-cause mortality between lowest and highest quintiles of ketone body concentrations (HR, 1.5 [95% CI, 1.0-1.9]; P=0.007). Ketone body levels remained associated with incident heart failure after adjusting for cardiovascular disease confounders (HR, 1.2 [95% CI, 1.0-1.3]; P=0.02). Using K-means cluster analysis, we identified a cluster with higher levels of ketone bodies, citrate, interleukin-6, and B-type natriuretic peptide but lower levels of pyruvate, body mass index, and estimated glomerular filtration rate. The cluster with elevated ketone body levels was associated with higher all-cause mortality (HR, 1.7 [95% CI, 1.1-2.7]; P=0.01). Conclusions Higher concentrations of ketone bodies predict incident heart failure and all-cause mortality in an older US population, independent of metabolic and cardiovascular confounders. This association suggests a potentially important relationship between ketone body metabolism and aging.

Prognostic impact of cachexia by multi-assessment in older adults with heart failure: FRAGILE-HF cohort study.

Cachexia substantially impacts the prognosis of patients with heart failure (HF); however, there is no standard method for cachexia diagnosis. This study aimed to investigate the association of Evans's criteria, consisting of multiple assessments, with the prognosis of HF in older adults. This study is a secondary analysis of the data from the FRAGILE-HF study, a prospective multicentre cohort study that enrolled consecutive hospitalized patients aged ≥65years with HF. Patients were divided into two groups: the cachexia and non-cachexia groups. Cachexia was defined according to Evans's criteria by assessing weight loss, muscle weakness, fatigue, anorexia, a decreased fat-free mass index and an abnormal biochemical profile. The primary outcome was all-cause mortality, as assessed in the survival analysis. Cachexia was present in 35.5% of the 1306 enrolled patients (median age [inter-quartile range], 81 [74-86] years; 57.0% male); 59.6%, 73.2%, 15.6%, 71.0%, 44.9% and 64.6% had weight loss, decreased muscle strength, a low fat-free mass index, abnormal biochemistry, anorexia and fatigue, respectively. All-cause mortality occurred in 270 patients (21.0%) over 2years. The cachexia group (hazard ratio [HR], 1.494; 95% confidence interval [CI], 1.173-1.903; P=0.001) had a higher mortality risk than the non-cachexia group after adjusting for the severity of HF. Cardiovascular and non-cardiovascular deaths occurred in 148 (11.3%) and 122 patients (9.3%), respectively. The adjusted HRs for cachexia in cardiovascular mortality and non-cardiovascular mortality were 1.456 (95% CI, 1.048-2.023; P=0.025) and 1.561 (95% CI, 1.086-2.243; P=0.017), respectively. Among the cachexia diagnostic criteria, decreased muscle strength (HR, 1.514; 95% CI, 1.095-2.093; P=0.012) and low fat-free mass index (HR, 1.424; 95% CI, 1.052-1.926; P=0.022) were significantly associated with high all-cause mortality, but there was no significant association between weight loss alone (HR, 1.147; 95% CI, 0.895-1.471; P=0.277) and all-cause mortality. Cachexia evaluated by multi-assessment was present in one third of older adults with HF and was associated with a worse prognosis. A multimodal assessment of cachexia may be helpful for risk stratification in older patients with HF.

Temporal trends in heart failure over 11 years in the aging Korean population: A retrospective study using the national health insurance database.

Understanding national trends of heart failure (HF) is crucial for establishing prevention and treatment strategies. We aimed to investigate the 11-year trends of HF in the South Korean population. Using the Korean National Health Insurance Service database, we identified 3,446,256 patients with HF between 2004 and 2014. The prevalence of HF was 1.42% in 2004, steadily increasing to 1.98% in 2014. However, the age-adjusted prevalence of HF remained stable (1.43% in 2014). The incidence of HF was 6.1/1000 person-years in 2004 and remained at similar levels, reaching 5.4/1000 person-years in 2014. The age-adjusted incidence of HF slowly decreased to 3.94/1000 person-years in 2014. The event rate for hospitalized patients with HF remained stable increasing from 1.40 in 2004 to 1.87/1000 person-years in 2014, and the age-adjusted event rate of hospitalized HF decreased to 1.22 in 2014. In South Korea, between 2004 and 2014, the prevalence of HF increased while the incidence of HF remained stable. Furthermore, the age-adjusted HF prevalence was stable, and the age-adjusted incidence decreased. This indicates that the aging population is the main cause of the increasing national burden associated with HF and that further attention is warranted in the management of HF in older adults.

Global Burden of cardiomyopathy and myocarditis in the older adults from 1990 to 2019.

BackgroundCardiomyopathy and myocarditis (CM-MC) are common chronic diseases causing heart failure in older adults. We aimed to analyze the burden of CM-MC in older adults aged 60–89 years at the global, regional, and national levels in 204 countries from 1990 to 2019.MethodsDetailed data on CM-MC from 1990 to 2019 were analyzed from the Global Burden of Diseases Study 2019, including incidence, mortality, disability-adjusted life years (DALYs) and the proportion of deaths caused by different risks factors. All results are presented as numbers, age-standardized rates per 100,000 person-years and estimated annual percentage change (EAPC) with an uncertainty interval of 95%.ResultsGlobally, there were 475,458 (339,942–638,363) incidence cases from CM-MC in 2019; with an age-standardized incidence rate (ASIR) of 16 (13–19.3) per 100,000 person-years. And there were 185,308 (154,610–200,448) deaths, with the age-standardized mortality rate (ASMR) being 4.4 (3.7–4.8). CM-MC resulted in 3,372,716 (2,931,247–3,693,622) DALYs, with an age-standardized DALYs rate (ASDR) of 114.8 (98.7–126.1). Estimated annual percentage change (EAPCs) for ARIS, ARMS, and ARDS has decreased. At the national level, the United States of America had the highest mortality [21,372 (18,924–24,241)] and disability-adjusted life years [407,712 (370,234–470,165)]. And China had the highest number of incident cases [122, 266 (85,925–166,095)]. Globally, high systolic blood pressure and alcohol consumption were the top two risk factors for the proportion of CM-MC deaths.ConclusionCM-MC is still an important cause of early death and chronic disability in older adults. Based on this study, public health agencies should seek more effective methods to prevent and treat CM-MC.

Heart Failure in Older Adults: Medical Management and Advanced Therapies.

As the population ages and the prevalence of heart failure increases, cardiologists and geriatricians can expect to see more elderly patients with heart failure in their everyday practice. With the advancement of medical care and technology, the options for heart failure management have expanded, though current guidelines are based on studies of younger populations, and the evidence in older populations is not as robust. Pharmacologic therapy remains the cornerstone of heart failure management and has improved long-term mortality. Prevention of sudden cardiac death with implantable devices is being more readily utilized in older patients. Advanced therapies have provided more options for end-stage heart failure, though its use is still limited in older patients. In this review, we discuss the current guidelines for medical management of heart failure in older adults, as well as the expanding literature on advanced therapies, such as heart transplantation in older patients with end-stage heart failure. We also discuss the importance of a multidisciplinary care approach including consideration of non-medical co-morbidities such as frailty and cognitive decline.

Cardiac Structure and Function and Diabetes-Related Risk of Death or Heart Failure in Older Adults.

BackgroundWhether cardiac structure and function abnormalities associated with dysglycemia are sufficient to explain the increased risk of death or heart failure (HF) remains unclear.Methods and ResultsWe analyzed 6059 participants (mean age, 75±5 years; 58% women; and 22% Black individuals) who attended the ARIC (Atherosclerosis Risk in Communities) study visit 5 examination (2011–2013). Participants were categorized as no diabetes, pre‐diabetes, and diabetes (on the basis of medical history and glycated hemoglobin values). We assessed whether diabetes modified the association between echocardiographic measures of cardiac structure and function and the composite of all‐cause death or HF hospitalization and then estimated the extent to which the increased risk of the composite outcome associated with diabetes was explained by cardiac structure and function. Diabetes was prevalent in 33.5% of the subjects. Death or HF occurred in 1111 (18%) at a rate of 3.6 per 100 person‐years. Both measures of cardiac structure and function and diabetes status were significantly associated with worse prognosis after accounting for clinical confounders. While diabetes was consistently associated with a higher risk of events, it did not significantly modify the association between cardiac abnormalities and the risk of death or HF, except for subjects with higher left atrial volume who showed higher relative risk of events (P for interaction <0.001). Measures of cardiac structure and function accounted for ≈16% of the increased risk of death or HF associated with diabetes. Similar results were observed analyzing subjects without prevalent heart disease.ConclusionsIn a biracial cohort of older adults, the increased risk of events associated with diabetes was partially explained by cardiac structure and function abnormalities.

Body Composition and Incident Heart Failure in Older Adults: Results From 2 Prospective Cohorts.

BackgroundAging is associated with central fat redistribution and skeletal muscle decline, yet the relationships of tissue compartments with heart failure (HF) remain incompletely characterized. We assessed the contribution of body composition to incident HF in elders.Methods and ResultsParticipants from 2 older cohorts who completed dual‐energy X‐ray absorptiometry (DEXA) and, in one cohort, computed tomography were included. We evaluated associations with incident HF for DEXA principal components (PCs) and total lean, appendicular lean, total fat and trunk fat mass; and for computed tomography measures of abdominal visceral and subcutaneous fat, thigh muscle, intermuscular fat area and thigh muscle density. DEXA analysis included 3621, and computed tomography analysis 2332 participants. During median follow‐up of 11.8 years, 927 participants developed HF. DEXA principal components showed no relationship with HF. After adjustment for height, weight, and cardiovascular risk factors, total lean mass was near significantly associated with higher HF (hazard ratio [HR], 1.25 per SD [1.00–1.56]), whereas total fat mass and thigh muscle density were significantly related to lower HF (HR, 0.82 [0.68–0.99] and HR, 0.87 [0.78–0.97], respectively). Patterns were similar for HF subtypes. The relationships with HF for total lean and fat mass were attenuated after adjusting for intercurrent atrial fibrillation or excluding high natriuretic peptide levels.ConclusionsTotal lean mass was positively associated, while total fat mass and thigh muscle density were inversely associated, with incident HF. These findings highlight the limitations of DEXA for assessment of HF risk in elders and support the preeminence of computed tomography–measured skeletal muscle quality over mass as a determinant of HF incidence.

The influence of heart failure on clinical and economic outcomes among older adults ≥75 years of age with acute myocardial infarction

We aimed to evaluate the influence of heart failure (HF) on clinical and economic outcomes among older adults ≥75 years of age during their acute myocardial infarction (AMI) admission in large population-based study from the United States. We also evaluated the clinical characteristics associated with the presence of HF and the predictors of mortality, healthcare utilization, and cost among older adults with AMI. From January 1, 2000, to December 31, 2016, AMI admission was identified using the primary diagnosis and concomitant HF was identified using any non-primary diagnoses in the Premier Healthcare Database. Of the 468,654 patients examined, 42,946 (9%) had concomitant HF during their AMI admission. These patients were older, more often female, and were more likely to be White. Patients with concomitant HF were more likely to be frail than non-HF patients (59% vs 15%, P < .001). The mean (SD) Elixhauser comorbidity index was 2.6 (2.5) vs 0.4 (1.1), P< .001 in the AMI with HF vs AMI only group. The use of percutaneous coronary intervention in those with AMI and HF was lower than those with AMI only (15% vs 31%, P< .001). The overall mortality rate for those with HF was 12%, the median [IQR] hospital length of stay was 5 [3,9] days, and only 25% of patients were discharged home. A higher proportion of patients were discharged to rehabilitation or hospice if they had AMI and HF (Rehabilitation: 33% vs 20%, P< .001; Hospice: 5% vs 3%, P< .001). The mean unadjusted cost of an AMI hospitalization in patients with concomitant HF was lower ($12,411 ± $14,860) than in those without HF ($15,828 ± $19,330). After adjusting for age, gender, race, hypertension, frailty, revascularization strategy, and death, the average cost of hospitalization attributed to concomitant HF was +$1,075 (95% CI +876 to $1,274) when compared to AMI patients without HF. In patients ≥75 years of age, AMI with concomitant HF carries higher risk of death, but at ages ≥85 years, the risk difference diminishes due to other competing risks. HF was also associated with longer hospital length of stay and higher likelihood of referral to hospice and rehabilitation facilities when compared to older patients without HF. Care for these older adults is associated with increased hospitalization costs. Measures to identify HF in older adults during their AMI admission are necessary to optimize health outcomes, care delivery, and costs.

Effect of Family-Centered Empowerment Model on the Care Burden of the Caregivers of Older Adults with Heart Failure

Background: Developing a chronic disease, like heart failure in older adults disrupts the foundations of the family and imposes a heavy burden on family members. The aim of this study was to determine the effect of the Family-Centered Empowerment Model (FCEM) on the care burden of family caregivers of older adults with heart failure. Methods: It was a quasi-experimental study with a controlled before and after design, which was conducted on 80 primary caregivers of older adults with heart failure referring to health centers affiliated with Kashan University of Medical Sciences, Kashan, Iran. The subjects were non-randomly assigned to either the control (n=40) or intervention (n=40) groups. The program was implemented based on the concepts of the model (perceived threat, self-efficacy, self-esteem, and evaluation) in eight 2-hour sessions, twice a week for four consecutive weeks. Both groups answered the Zarit Burden Interview (ZBI) in the beginning, in the end, and one month after the study. The data were analyzed by Chi-square, t-test, and the repeated measures ANOVA using SPSS v. 16 software. Results: There was no significant difference between the two groups regarding the pretest mean score of care burden (P&gt;0.05). However, the groups’ mean score of care burden was significantly different immediately after the intervention (P&lt;0.05) and one month after the study (P&lt;0.05). The repeated measures ANOVA illustrated a significant difference between the mean scores of care burden in the three measurement time points (P&lt;0.0001). Conclusion: Implementation of the FCEM model reduces the burden of care in caregivers of older adults with heart failure. It is suggested that this model be used in training programs for older adults with heart failure and their caregivers.

Temporal Trends in Post Myocardial Infarction Heart Failure and Outcomes Among Older Adults

BackgroundWe sought to determine national trends and long term outcomes of post myocardial infarction (MI) heart failure. An MI can be complicated by heart failure; there are limited data describing the contemporary patterns and clinical implications of post-MI heart failure. Methods and ResultsWe studied patients with an MI aged 65 years or older from 2000 to 2013 in a Medicare database. New-onset heart failure after an MI was defined as either heart failure during the index MI admission or a hospitalization for heart failure within 1 year of the index MI event. A trend analysis of the incidence of heart failure was performed, and differences were examined by Gray tests. The 5-year mortality rates were evaluated and differences among heart failure cohorts were ascertained by Gray tests. There were a total of 1,531,638 patients with an MI and 565,291 patients had heart failure (36.0%). The rate of heart failure during index admission was 32.3% and the frequency of heart failure hospitalization within 1 year was 10.4%. Patients with heart failure were older (81 years vs 77 years). The temporal trend from 2001 to 2012 suggested a decrease in the incidence of heart failure during index admission (2001: 34.7%, 2012: 31.2%, Ptrend < .01), as well as heart failure hospitalization within 1 year (2001: 11.3%, 2012: 8.7%, Ptrend < .01). The 5-year mortality rate among patients without heart failure was 38.4% and for patients with any heart failure it was 68.7%. ConclusionsPost-MI heart failure in older adults occurs in 1 in 3 patients within 1 year; heart failure portends significantly higher long-term mortality.

Adult height and incidence of atrial fibrillation and heart failure in older men: The British Regional Heart Study.

AimsTaller stature has been associated with increased risk of atrial fibrillation (AF). AF and heart failure (HF) often co-occur but the association between height and risk of HF in older adults has not been well studied. We have examined the association between height and incident AF and incident HF in older adults.MethodsProspective study of 3346 men aged 60–79 years with no diagnosed HF, myocardial infarction or stroke at baseline (1998–2000) followed up for a mean period of 16 years, in whom there were 294 incident HF cases and 456 incident AF. Men were divided into 5 height groups: <168.2, 168.2–172.5, 172.6–176.9, 177.0–183.0 and >183.0 cms based on the 25th, 50th, 75th and 95th centiles distribution of height.ResultsCVD risk factors tended to decrease with increasing height but a positive association was seen between height and electrocardiographic QRS duration and incident AF. Both short stature (<168.2 cm) and tall stature (>183.0 cm) was associated with significantly increased risk of HF in age-adjusted analysis compared to those in the second height quartile [HR (95 %CI) = 1.62 (1.15, 2.26) and 2.04 (1.23, 3.39) respectively]. In short men the increased risk remained after adjustment for adverse CVD risk factors; in tall men the association was largely associated with AF and QRS duration.ConclusionTall stature is associated with significantly increased risk of AF leading to increased risk of HF. Short stature was associated with increased HF risk which was not explained by known adverse CVD risk factors.

Copeptin as a predictive marker of incident heart failure.

AimsHeart failure (HF) is a common disease with increasing prevalence and poor prognosis. The vasopressin (VP) marker copeptin predicts development of diabetes mellitus, diabetic heart disease, coronary artery disease, and premature mortality. Copeptin is elevated in HF patients and predicts a worse outcome. This study aims to investigate whether copeptin can predict HF development.MethodsCopeptin was analysed in 5297 individuals (69.6% men) without prevalent HF from the Malmö Preventive Project, a population‐based prospective cohort. Cox proportional hazards models were used to analyse risk of incident HF by copeptin levels after adjusting for conventional cardiovascular risk factors.ResultsDuring a median follow‐up time of 11.1 years, 350 subjects (6.6%) were diagnosed with HF. Of these events, 99 were classified as myocardial infarction (MI) related HF and 251 as non‐MI‐related HF. Individuals in the top quartile of copeptin had, after multivariate adjustment for conventional risk factors (age, sex, systolic blood pressure, diabetes mellitus, body mass index, antihypertensive therapy, smoking, low‐density lipoprotein cholesterol, and high‐density lipoprotein cholesterol), a significantly increased risk of developing HF by 1.63 [confidence interval (CI) 1.20–2.21] for HF compared with the reference quartile 1. After adjustment for conventional risk factors, the hazard ratio (HR) per standard deviation increase of log‐transformed copeptin for any HF was 1.30 (95% CI 1.17–1.46), whereas it was 1.39 (CI 1.13–1.71) for MI‐related HF and 1.26 (CI 1.11–1.44) for non‐MI‐related HF. The associations remained after additional adjustment for estimated glomerular filtration rate [HR 1.24 (95% CI: 1.10–1.40)] and for pro atrial natriuretic peptide on top of conventional risk factors [HR 1.14 (95% CI: 1.02–1.28)].ConclusionsElevated copeptin predicts development of HF in older adults. Copeptin is a risk marker of VP‐driven HF susceptibility and a candidate to guide prevention efforts of HF targeting the VP system.

95 Lack of Evidence for Reduced Efficacy of Medical Therapy for Heart Failure in Older Adults

Abstract Introduction There are almost a million people with heart failure (HF) in the UK; the incidence increases sharply with age. Older adults receive less evidence-based therapy with few trials specifically examining therapeutic efficacy in older age groups representative of a contemporary UK HF population. Concern that efficacy is less in older adults may underlie under-prescription. With important recent advances in HF therapy, we reviewed the contemporary evidence base for any signal of different efficacy in older adults. Methods We reviewed recent RCTs of medical therapy for heart failure alongside meta-analyses updated with recent therapies including Angiotensin-Neprilysin inhibitors and SGLT2 inhibitors. For those trials in which effect size was presented for age subgroups we compared the effect size. Results Of 68 randomised controlled trials, 10 presented effect sizes for different age groups. The median average cut-off between younger and older age groups was 66 years (IQR 65 to 72.5 years) and the highest cut-off used was 75 years. The median hazard ratio was 0.77 (IQR 0.67 to 0.80) for the younger age group and 0.76 (IQR 0.73 to 0.88) for the older age group. In 8 of the 10 trials, the effect size in the oldest age group was statistically significant on its own including Sacubitril-Valsartan and Dapagliflozin. Conclusion When considering the medical therapeutic armamentarium for heart failure as a totality, there is no evidence it is any less effective in older adults than younger adults. The recent Zannad et al cross-trial analysis supported this showing significant additional life years in the patients over 80 years on HF therapy. Whilst there may be practical and frailty-related reasons for not prescribing life-prolonging therapy, the proportional survival benefits of these medications is similar in older adults. This should be utilised where practically possible and discussed with patients when making an informed choice.

Association between instrumental activities of daily living with the change in left ventricular function in older patients with cardiovascular disease.

Left ventricular dysfunction is a pathophysiologic characteristic of heart failure. Impaired instrumental activities of daily living are associated with an elevated risk of mortality and heart failure in older adults. Nevertheless, the relationship between these activities and left ventricular function changes remains unclear. We determined whether instrumental activities of daily living are associated with subsequent left ventricular function changes in older cardiovascular disease patients. This retrospective cohort study included 383 outpatients with cardiovascular disease (74.5 ± 5.3years, 273 males). Patients were divided according to the Frenchay activities index tertile and followed for six months after cardiovascular disease diagnosis. The left ventricular ejection fraction and annular early diastolic velocity (e') were measured for left ventricular systolic and diastolic function, respectively, at baseline and after one year. After adjusting for confounders, changes in the left ventricular ejection fraction were not significantly different. However, changes in the e' in the highest tertile group were significantly greater than in other groups. In the general linear model with multiple regression analysis, Frenchay activities index independently predicted the absolute change in the e'. In older cardiovascular disease patients, higher instrumental activities of daily living were associated with preserved left ventricular relaxation.
