Trends and Disparities in Heart Failure Mortality Among Hypertensive Older Adults in the United States: A 22-Year Retrospective Study.

Hypertension (HTN) is a significant risk factor for heart failure (HF), and both significantly contribute to cardiovascular mortality. This study aims to examine trends and disparities in HF-related mortality among hypertensive older adults (≥65years) in the United States from 1999 to 2020. Centers for Disease Control and Prevention-Wide-ranging Online Data for Epidemiologic Research (CDC-WONDER) database data were analyzed, focusing on HTN as the underlying cause and HF as the contributing cause of death. Age-adjusted mortality rates (AAMRs) and crude rates were stratified by gender, race/ethnicity, age groups, urban-rural status, and geographic regions. The Joinpoint regression program was used to calculate annual percentage changes (APCs) and average annual percentage changes (AAPCs). A total of 259079 HF-related deaths occurred among hypertensive older adults, with an overall AAMR increase from 11.27 in 1999 to 41.05 in 2020, indicating a clear upward trend (AAPC: 5.51%). Females had higher AAMRs (28.57) than males (25.56); however, males showed a steeper rise in mortality (AAPC: 6.15% vs. 5.23%). Non-Hispanic Blacks had the highest AAMR (43.99), while NH Whites exhibited the most significant increase (AAPC: 5.92%). Mortality rates were highest in the West (AAMR: 34.57) and lowest in the Northeast (21.44). Non-metropolitan areas had a higher AAMR than metropolitan areas (30.69 vs. 26.52). These findings emphasize the necessity for targeted interventions to diminish disparities and tackle increasing mortality rates in vulnerable populations, especially among women, NH Blacks, individuals in the West, and those living in non-metropolitan areas.

Natural History, Phenotype Spectrum, and Clinical Outcomes of Desmin (DES)-Associated Cardiomyopathy.

Pathogenic/likely pathogenic (LP) desmin (DES) variants cause heterogeneous cardiomyopathy and skeletal myopathy phenotypes. Limited data suggest a high incidence of major adverse cardiac events (MACEs), including cardiac conduction disease, sustained ventricular arrhythmias (VA), and heart failure (HF) events (HF hospitalization, left ventricular assist device/cardiac transplant, HF-related death) in patients with pathogenic/LP DES variants. However, pleiotropic presentation and small cohort sizes have limited clinical phenotype and outcome characterization. We aimed to describe the natural history, phenotype spectrum, familial penetrance and outcomes in patients with pathogenic/LP DES variants through a systematic review and individual patient data meta-analysis using published reports. We searched Medline (PubMed) and Embase for studies that evaluated cardiac phenotypes in patients with pathogenic/LP DES variants. Cardiomyopathy diagnosis or occurrence of MACE was considered evidence of cardiac involvement/penetrance. Lifetime event-free survival from cardiac conduction disease, sustained VA, HF events, and composite MACE was assessed. Of the 4212 screened publications, 71 met the inclusion criteria. A total of 230 patients were included (52.6% men, 52.2% probands, median age: 31 years [22.0-42.8] at first evaluation, median follow-up: 3 years [0-11.0]). Overall, 124 (53.9%) patients were diagnosed with cardiomyopathy, predominantly dilated cardiomyopathy (14.8%), followed by restrictive cardiomyopathy (13.5%), whereas other forms were less common: arrhythmogenic cardiomyopathy (7.0%), hypertrophic cardiomyopathy (6.1%), arrhythmogenic right ventricular cardiomyopathy (5.2%), and other forms (7.4%). Overall, 132 (57.4%) patients developed MACE, with 96 (41.7%) having cardiac conduction disease, 36 (15.7%) sustained VA, and 43 (18.7%) HF events. Familial penetrance of cardiac disease was 63.6% among relatives with pathogenic/LP DES variants. Male sex was associated with an increased risk of sustained VA (hazard ratio, 2.28; P=0.02) and HF events (hazard ratio, 2.45; P=0.008). DES cardiomyopathy exhibits heterogeneous phenotypes and a distinct natural history, characterized by high familial penetrance and a substantial MACE burden. Male patients face a higher risk of sustained VA events.

Prognostic Value of Myocardial T1 Mapping for Predicting Adverse Events in Hypertrophic Cardiomyopathy.

In patients with hypertrophic cardiomyopathy, the prognostic value of myocardial T1 and extracellular volume fraction for adverse cardiovascular events has not been well defined. A total of 663 consecutive participants with hypertrophic cardiomyopathy who underwent 3T cardiovascular magnetic resonance were recruited. The follow-up end points included heart failure (HF)-related death, HF hospitalization, and sudden cardiac death or aborted sudden cardiac death. On Cox proportional hazards regression multivariable analyses, global native T1 excluding late gadolinium enhancement areas (hazard ratio [HR], 1.04 [95% CI, 0.99-1.09]; P=0.094) and global extracellular volume fraction excluding late gadolinium enhancement (HR, 1.02 [95% CI, 0.95-1.10]; P=0.565) were not associated with sudden cardiac death. Conversely, global native T1 (HR, 1.08 per 10 ms increase [95% CI, 1.02-1.16], P=0.014; HR, 1.05 per 10 ms increase [95% CI, 1.01-1.09]; P=0.009) and global extracellular volume fraction (HR, 1.23 per 1% increase [95% CI, 1.11-1.36], P<0.001; HR, 1.10 per 1% increase [95% CI, 1.04-1.16]; P<0.001) were independently associated with HF-related death and the composite end point of HF-related death or HF hospitalization in multivariable Cox models, respectively. In this study of patients with hypertrophic cardiomyopathy, we found global native T1 and global extracellular volume fraction (excluding late gadolinium enhancement) to be both independently associated with HF-related events, but not sudden cardiac death in multivariable analysis. These findings are hypothesis-generating and will require external validation in larger cohorts. URL: https://www.chictr.org.cn; Unique identifier: ChiCTR1900024094.

Heart Failure and Sepsis-Related Mortality Trends in the United States, 1999 - 2019: An Analysis of Gender, Race/Ethnicity, and Regional Disparities.

Heart failure (HF) and sepsis are significant causes of disease burden and mortality among the elderly population of the USA. HF causes fluid overload, which complicates the treatment approach when patients develop sepsis necessitating fluid resuscitation. While individual disease states have been studied extensively, the trends in mortality for concurrent sepsis and HF are not well known. Mortality trends due to sepsis and HF in individuals aged 65 and older in the USA from 1999 to 2019 were analyzed using the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research (CDC WONDER) database. Differences in age-adjusted mortality rate (AAMR) and average annual percent change (AAPC) over the past two decades based on gender, race, region, and place of death were examined. Between 1999 and 2019, there were a total of 5,887,799 deaths related to HF, 2,584,523 deaths related to sepsis, and 250,115 deaths related to both HF and sepsis. There was also a decrease in AAMR for HF-related (AAPC -0.80%) and sepsis-related (AAPC -0.28) deaths but an increase in combined HF and sepsis-related AAMR (AAPC 1.06%). Men had consistently higher AAMRs compared to women and a greater increase in mortality (AAPC in men 1.53% vs. women 0.56%). African American patients had a higher AAMR than White patients throughout the study period, though the difference narrowed. African Americans saw a decrease in overall HF and sepsis-related AAMR from 48.90 to 40.56 (AAPC -0.83), whereas AAMR for the White population increased from 27.26 to 33.81 (AAPC 1.37). Regionally, the Northeast had the highest AAMR in 1999 (32.32) but decreased to the lowest AAMR by 2019 (30.77). Totally, 203,368 (81.31%) of all deaths related to HF and sepsis were in medical facilities, 18,430 (7.37%) were in home/hospice facilities, and 24,713 (9.88%) in nursing homes. HF and sepsis-related mortality in the elderly population increased over the past two decades, with men and African Americans at disproportionately higher risk.

Trends and disparities in heart failure-related mortality in the US adult population from 1999 to 2020.

The rising incidence of heart failure (HF) among the U.S. population has become a major concern for healthcare providers. This study aims to assess mortality trends related to HF across different age groups, racial demographics, and geographic locations from 1999 to 2020. This descriptive analysis uses death certificate data from the CDC WONDER database to track mortality trends among HF patients from 1999 to 2020. Log-linear regression models were used to delineate trends. The study used deidentified public data, complying with ethical standards. Over 21 years, 1,426,657 HF-related deaths were recorded in individuals aged 15 and older, with a slight overall increase in mortality (AAPC = 0.11). Mississippi recorded the highest age-adjusted mortality rates (AAMRs) at 58.0 per 100,000. The Midwest showed the highest regional mortality rates, while the oldest individuals (≥ 85) exhibited the highest crude mortality rate (CMR) of 663.9. Males consistently demonstrated higher AAMRs than females, despite females accounting for 57.6% of the deaths. Black ancestry individuals experienced the highest mortality rates, with rising trends, particularly in non-metropolitan areas. After 2012, significant increases in mortality were noted, especially in individuals over 85, with stable rates in younger demographics. Males and Black ancestry individuals are disproportionately affected, demonstrating the need for targeted interventions.

Abstract 4143872: Mode of Death in Heart Failure with Preserved Ejection across the Kidney Function Spectrum: Pooled Individual-Patient Level Analysis of 5 Trials

Introduction: Patients with comorbid heart failure (HF) and chronic kidney disease (CKD) face excess risks of mortality, but limited data are available examining specific modes of death across the spectrum of kidney function. Methods: We leveraged individual patient level data from 5 trials of HF with mildly reduced or preserved ejection (CHARM-Preserved, I Preserve, TOPCAT [Americas region], PARAGON-HF, and DELIVER). Causes of death (sudden, heart failure, other CV, and non-CV) were adjudicated by clinical events committees in each respective trial. Results: Among 17,947 patients across the 5 trials with available eGFR data, mean age was 71.6 ± 9.0 years, 51% were women, median NT-proBNP was 840 [25-75th percentile 424, 1566] pg/ml. Overall, 2084 (12%) had eGFR ≥90 mL/min/1.73m2, 7977 (44%) had eGFR 60 - &lt; 90, 4701 (26%) had eGFR 45-60, 3185 (18%) had eGFR &lt;45. During a mean of 2.9 years of follow-up, 3,140 patients died. All-cause death rate was greater in the lower eGFR groups, driven by greater rates of HF and non-CV death. Rates of CV and non-CV death were 5.7/100 patient years (py) and 4.4/100py in patients with eGFR &lt;45 and 2.7/100py and 1.3/100py in patients with eGFR &gt;90 (Table and Figure). HF-related death rate was markedly greater in participants with eGFR &lt;45 (2.0/100py) compared to patients with eGFR&gt;90 (0.3/100py) Conclusions: Among nearly 18,000 patients across contemporary HFmrEF/HFpEF clinical trials, mortality was markedly higher at lower ranges of kidney function, driven mostly by higher non-CV death and HF-related death.

Abstract 4122048: Disparities in Heart Failure-Related Mortality Among Reproductive-Aged Women in the United States from 1999 to 2019

Introduction: Heart failure (HF) majorly affects the elderly, but can also affect the younger population. This study aims to examine the trends of HF-related deaths among reproductive-aged women in the United States (US). Method: We conducted a retrospective analysis using the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database, extracting data through ICD-10 codes I11, I13.0, I13.2, and I50 to find HF-related deaths among women aged 15-44 from 1999 to 2019. We examined demographic disparities in HF mortality rates over time, considering age, ethnicity, and geographic areas. Results were reported as age-adjusted mortality rate (AAMR) and 95% confidence interval (CI). Joinpoint regression assessed trend changes and annual percentage change (APC). Results: Between 1999 and 2019, a total of 43,683 women aged 15-44 died from HF in the US, with an AAMR of 3.5 per 100,000 (95% CI: 3.5-3.5). The AAMR increased from 2.6 in 1999 to 4.8 in 2019. Non-Hispanic Black women had the highest AAMR at 10.2, while Hispanics had the lowest at 1.8. Geographically, the South was the most affected region with an AAMR of 4.6, contributing to nearly half (48.9%) of all deaths. States including Massachusetts, Oregon, New Hampshire, and Minnesota had the lowest AAMRs. Rural areas showed a higher AAMR compared to urban areas (4.4 Vs. 3.3). The age group (35-44) accounted for the majority of deaths (73.7%). Conclusion: HF-related mortality among reproductive-aged women increased from 1999 to 2019, with the highest burden among non-Hispanic Black women and those in the Southern region. Enhancing access to care, particularly in rural areas, and implementing targeted prevention programs are vital to reducing mortality rates.

Abstract 4122035: The Distinct Natural History, Phenotype Spectrum, Familial Penetrance and Clinical Outcomes in Desmin (DES)-Associated Cardiomyopathy

Background: Pathogenic/likely pathogenic variants (P/LP) in the desmin (DES) gene cause heterogeneous cardiomyopathy and skeletal myopathy phenotypes. Research Questions: Limited data suggest that patients with P/LP DES variants have a high incidence of major adverse cardiac events (MACEs), including cardiac conduction disease requiring pacemaker implantation (CCD-PM), sustained ventricular arrhythmias (VA), and heart failure (HF) events (HF hospitalization, heart transplant, HF-related death). However, small cohort sizes have limited full clinical characterization. Aims: We aimed to describe the natural history, phenotype spectrum, familial penetrance and MACE in patients with P/LP DES variants identified via clinical genetic testing. Methods: We conducted a systematic review and individual patient data meta-analysis of cardiac and skeletal myopathy phenotypes and MACE (CCD-PM, VA and HF events) in patients with P/LP DES variants by retrieving publications from Medline (PubMed) and Embase. Diagnosis of cardiomyopathy or MACE were both considered evidence of cardiac involvement. Results: Out of 4,212 screened records, 72 met inclusion criteria. In total, 230 patients were included (52.6% male, 52.2% probands, median age: 31 years at first evaluation [22.0; 42.8]). Eighty-five (37.0%) patients showed isolated cardiac involvement, 89 (38.7%) cardiac and skeletal muscle involvement, 39 (17.0%) only skeletal muscle involvement, and 17 (7.4%) had neither phenotype. Overall, 130 (56.5%) patients were diagnosed with a cardiomyopathy and 134 (57.4%) patients developed MACE (96 [41.7%] had CCD-PM, 36 [15.7%] sustained VA, and 43 [18.7%] HF events). Familial cardiac disease penetrance was 69.1% (76/110) in relatives with P/LP DES variants. Out of 40 patients who presented with isolated CCD-PM phenotype, 18 (45.0%) were diagnosed with a cardiomyopathy after 6 [2.0; 16.0] years of follow-up. In multivariable analysis, male sex and non-missense variants were associated with higher risk of sustained VA (HR 2.71, p=0.008, and HR 4.62, p&lt;0.001, respectively) and HF events (HR 2.63, p=0.005, and HR 2.79, p=0.015). Conclusions: DES cardiomyopathy demonstrates a distinct natural history, characterized by high familial penetrance and a high MACE burden. Male patients and those carrying non-missense variants are at higher risk for sustained VA events and may benefit from primary preventive ICD implantation even in the absence of severe LV systolic dysfunction.

Abstract 4139875: Trends in Comorbid Diabetes Mellitus and Heart Failure-Related Mortality Among Older Adults: Demographic and Regional Analysis from CDC WONDER - 1999 to 2019

Background and Purpose: Older adults in the United States face worsening trends in the incidence and prevalence of comorbid diabetes mellitus (DM) and heart failure (HF). This study aimed to examine the trends in DM and HF-related mortality among adults ≥65 years in the United States. Methods: The Multiple Cause-of-Death data using CDC WONDER (Centers for Disease Control and Prevention Wide-Ranging OnLine Data for Epidemiologic Research) were analyzed for DM and HF-related deaths from 1999 to 2019 in adults ≥65 years. Age-adjusted mortality rates (AAMRs) per 100,000 population were determined and stratified by year, sex, race/ethnicity, and geographic region. Joinpoint regression was used to analyze trends in AAMRs using annual percent change (APC). Results: A total of 842,785 deaths occurred among older adults in the United States related to comorbid HF and DM. The overall AAMR for deaths due to comorbid DM and HF in older adults was 97.4. The AAMRs remained stable between 1999 and 2005. From 2005 to 2009, AAMRs steadily declined at an APC of -3.41 (95% CI: -4.75 to -0.52). Following a period of stability from 2009 to 2014, AAMRs increased at an APC of 2.80 (95% CI: 1.97 to 4.68) till 2019. Men (116.2) had consistently higher AAMRs than older women (84.8) throughout the study period. Upon stratification by race and ethnicity, AAMRs were observed to be highest in non-Hispanic (NH) American Indian or Alaska Native (144.1), followed by NH Black or African American (124.4), Hispanic or Latino (100.5), NH White (95.3), and NH Asian or Pacific Islander (62.0) populations. Non-metropolitan areas had higher AAMRs for comorbid HF and DM than metropolitan areas, with overall AAMRs of 126.9 and 90.9, respectively. States that fell into the top 90th percentile included Kentucky, Mississippi, Oklahoma, Oregon, Vermont, and West Virginia, which had twice the AAMRs than states that fell into the bottom 10th percentile, including Arizona, Florida, Hawaii, Massachusetts, Nevada, and New York. Conclusion: Our analysis revealed a concerning rise in mortality related to comorbid DM and HF in U.S. adults ≥ 65 years old since 2014. Men, NH American Indian and Alaska Native populations, and residents of non-metropolitan areas displayed the highest AAMRs. Future efforts focusing on improved risk assessment and the adoption of therapeutic therapies are needed for the effective management of patients with comorbid DM and HF to help alleviate the mortality burden.

Abstract 4131228: Where Adults with Advanced Heart Failure Die: Insights from the CDC-WONDER Database

Background: Adults with heart failure (HF) are becoming more and more prevalent. The location of death and related disparities in these patients are poorly understood. Aim: The purpose of the study was to look at the locations of adult deaths from HF and identify any age, race, or ethnicity-related variations over a 25-year period. Methods: The Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research Database provided death certificate data and the National Center for Health Statistics provided individual-level mortality data for the trend-level analysis of adults aged (20-64 and 65+ years) conducted from 1999-2023. Hospital, home, hospice and nursing home/long-term care were the categories for the places of death. Results: Between 1999 and 2023, a total of 7,644,759 adult deaths from HF were recorded (87.9% White, 53.4% female). HF-related deaths decreased from 1999 (3.60% and 143.6 AAMR) to 2010 (3.47% and 123.1 AAMR). From 2010 onwards, a gradual rise is seen, with the rate of HF deaths reaching 5.18% and 168.1 AAMR in 2023. Notably, deaths at home increased from 18.41% (50,648 of 275,132) in 1999 to 33.47% (132,470 of 395,826) in 2023 and deaths in hospice/nursing homes increased from 30.95% (85,144 of 275,132) in 1999 to 34.71% (116,634 of 336,014) in 2017 and then sudden fall was observed until 2023 to 29.54% (116,931 of 395,826). Older adults (65+) were more likely to die in inpatient facilities. Gender, ethnicity, and urbanization influenced the place of death, with males, whites, and those residing in large metropolitan areas more likely to die in medical facilities. Conclusion: Prioritize end-of-life planning for HF patients with poor prognosis, regardless of age, to improve quality of life and death.

Paracetamol and adverse cardiovascular outcomes in patients with heart failure

Abstract Background Paracetamol is the most widely used pain killer worldwide, yet its potential influence on cardiovascular events among patients with heart failure (HF) remains unclear. Thus, this study aims to investigate both the short-term and long-term effects of paracetamol use on all-cause mortality and cardiovascular events in HF patients. Methods Using the previously validated territory-wide clinical information registry, paracetamol use was identified among all eligible patients with HF (N = 211,409) from 2000 to 2020. A case-crossover design was used to investigate the associations between short-term use of paracetamols and all-cause mortality and cardiovascular outcomes. Defined daily dose (DDD) was used to evaluate the dose-response relationship. Additionally, the marginal structural design was applied to model paracetamol use as a time-varying exposure and evaluate its long-term effects during the follow-up period. Results Of all eligible subjects, the mean age was 73.2±12.3 years, and 43.6% was male. Over a median follow-up of 10.5 years (interquartile range: 5.7-15.8), 113,258 (53.6%) patients were re-hospitalised for HF, HF-related death occurred in 11,892 (5.6%) patients, incident myocardial infarction (MI) in 28223 (13.3%) patients, incident stroke in 26458 (12.5%) patients, cardiovascular death (CVD) in 72,175 (34.1%) patients and all-cause death in 123,505 (58.4%) patients. Associating HF rehospitalisation to previous paracetamol exposure using the case-crossover design displayed an elevated risk (OR 3.62, 95% CI 3.53-3.71). Associations were similar for MI (OR 5.77, 95% CI 5.50-6.05), stroke (OR 2.37, 95% CI 2.25-2.49), HF-related death (OR 1.86, 95% CI 1.75-1.98), CVD (OR 3.64, 95% CI 3.55-3.73), and all-cause mortality (OR 3.32, 95% CI 3.26-3.39). Moreover, compared with paracetamol users taking the reference dose, users of low, medium and high doses of paracetamol had 16%, 17% and 52% higher risk of HF rehospitalisation. During the long-term follow-up, the average weighted hazard ratio (HR) for HF rehospitalisation in paracetamol users was 2.48 (95% CI 2.46–2.50) as compared with paracetamol non-users after accounting for all-cause mortality as a competing risk. Similarly, the average weighted HR for incident MI or stroke was 2.71 (2.62-2.81) and 3.45 (3.34-3.57), respectively. However, neutral results were shown for HF-related death, CVD and all-cause mortality. Conclusion The use of paracetamol among patients with HF is common. Paracetamol was associated with adverse cardiovascular outcomes both in short-term and long-term follow-up with a dose-response relationship, while its impact on long-term mortality remained neutral. Future randomized controlled trials or experimental studies are warranted to gain a comprehensive understanding of the underlying mechanisms driving such associations between paracetamol and adverse cardiovascular outcomes.

The prognostic and incremental value of T1 mapping for predicting adverse events in hypertrophic cardiomyopathy

Abstract Background In patients with hypertrophic cardiomyopathy (HCM), the prognostic value of native T1 and extracellular volume fraction (ECV) for adverse cardiovascular events has not been well defined. Methods Consecutive 663 participants with HCM who underwent cardiovascular magnetic resonance (CMR) were recruited. The follow-up endpoints included heart failure (HF)-related death and sudden cardiac death (SCD) or aborted SCD. Results During the median follow-up time of 44 months (interquartile range [IQR]: 23 to 66.0 months), 56 (8.4%) participants reached composite endpoints including 38 (5.7%) with SCD or aborted SCD, 16 (2.4%) with HF-related death and 2 (0.3%) with heart transplantation. On multivariable Cox proportional hazards regression analyses, native T1 including late gadolinium enhancement (LGE) from three short axes were significantly associated with cardiac death (basal native T1: hazard ratio [HR], 1.06 per 10 ms increase; 95% confidence interval [CI], 1.02 to 1.09; middle native T1: HR, 1.05 per 10 ms increase; 95% CI, 1.01 to 1.09; apical native T1: HR, 1.04 per 10 ms increase; 95% CI, 1.02 to 1.07; all P &amp;lt; 0.05) after adjustment for non-sustained ventricular tachycardia, history of syncope, the extent of LGE, left atrial size, and NYHA class. Conversely, only basal ECV was associated with cardiac death (basal ECV including LGE area: HR, 1.08 per 1% increase, 95%CI, 1.03 to 1.13, P = 0.001; basal ECV excluding LGE: HR, 1.1 per 1% increase; 95%CI, 1.04 to 1.16; P &amp;lt; 0.001) In addition, participants with increased mean native T1 (≥1349.4 ms) or basal ECV(≥ 29.4%) were more likely to suffer from cardiac death in the entire study cohort or the subgroup with low LGE extent (&amp;lt;15%) or low ESC risk score (&amp;lt;6%) (all P &amp;lt; 0.05). Furthermore, the addition of mean LV native T1 (≥1349.4 ms) or basal ECV (≥ 29.4%) to current risk factors in the guidelines could further improve prediction for the composite endpoint (C-index increased to 0.719 from 0.521 for the AHA/ACC risk model, P &amp;lt; 0.001; C index increased to 0.709 from 0.514 for the ESC risk model; P &amp;lt; 0.001). Conclusions In this study of patients with HCM, mean native T1 of three short axes and basal ECV were independently associated with cardiac death and added incremental value to conventional clinical predictors for patients with HCM.Figure 1.Demonstrative images.Figure 2 Incremental Value of T1 mapping

Time taken for cardiology care and one-year results for primary care physicians' referrals for cardiology consultation in heart failure patients: clinical implications for heart failure management

Abstract Background and Purpose The clinical trajectory of patients with heart failure (HF) is characterised by frequent episodes of decompensation requiring urgent medical assistance, hospitalisations, and an increased risk of mortality. HF clinical guidelines recommend early visits by health professionals after hospital discharge, yet little evidence exists regarding the associations between delayed medical attention and outcomes in HF patients. To assess the clinical impact of the time taken to receive cardiology care for referrals from primary care physicians (PCPs) to a cardiology department in HF patients, we selected 6,859 HF patients who visited the cardiology service at least once between 2010 and 2021. Methods Using an interrupted time series regression model, we analysed the impact of integrating e-consultations into the healthcare model (implemented in 2013) and evaluated the time taken to receive cardiology care, as well as all-cause, cardiovascular (CV), and HF-related hospital admissions and mortality. The primary objective of this analysis was to examine the associations between delays in cardiology care following a PCP referral and 1-year outcomes (HF-related, cardiovascular, and total hospitalisations; and HF-related, cardiovascular, and total mortality). Results Almost 50% were women, and the mean age was 77.8 years. Arterial hypertension (79.6%), diabetes (34%), atrial fibrillation (51.4%), ischemic heart disease (20.4%), and cerebrovascular disease were the most prevalent comorbidities. The mean time from PCP referral to cardiology consultation in the overall population was 22.3 days: &amp;lt;8 days in 53.9%, 8-14 days in 17.1%, 15-30 days in 15.9%, and &amp;gt;30 days in 13.0% of patients, respectively. One year after cardiology consultation, 68.6% of patients required assistance in an Emergency Department; 22.5% were hospitalised for any cause, 14.9% for cardiovascular reasons, and 9.2% for HF-related issues. Moreover, total mortality at 1-year was 8.6%, comprising 4.3% cardiovascular mortality and 1.3% HF-related deaths. Multivariate analysis of the relationship between the time taken to receive cardiology care and 1-year outcomes revealed a significant increased risk associated with a longer delay in cardiology assistance, particularly evident in the subgroup of patients with previous hospital admissions due to worsening HF (see Table). Conclusions Throughout the follow-up period, a reduced time taken to receive care was independently associated with better 1-year outcomes. We believe that our experience can contribute to the development of a more efficient ambulatory care pathway for HF patients, especially those at high risk, such as those with a history of hospitalisation due to worsening events. Our findings further support the clinical guideline recommendation for early contact by health professionals following hospital discharge, extending it to include PCP referrals for cardiology consultations.

Impact of global longitudinal strain and anemia for predicting cardiovascular mortality in patients hospitalized for acute heart failure with atrial fibrillation

Abstract Background Iron deficiency is a prognostic factor in heart failure (HF) with reduced ejection fraction (EF). In patients with atrial fibrillation (AF) and HF, left ventricular EF (LVEF) measurements are imprecise due to irregular tachycardia, but it is unclear whether global longitudinal strain (GLS) and anemia assessment are prognostic. Purpose We examined whether GLS and anemia predict cardiovascular death (CD) in patients with acute HF complicated by AF. Methods We retrospectively enrolled patients aged 18 years or older with acute HF complicated by AF who were consecutively admitted to our hospital from January 2014 to December 2018. Exclusion criteria were acute coronary syndromes, no transthoracic echocardiogram performed within 30 days before or after admission, and missing data. All patients were followed up from admission to CD (due to myocardial infarction, HF, stroke or sudden death), or were censored at the date of last contact or 3 years. Anemia was defined as hemoglobin &amp;lt; 12 g/dL in females and hemoglobin &amp;lt; 13 g/dL in males. Patients were divided into four groups according to median GLS and anemia status. Results A total of 320 patients (mean age 79 ± 12 years, 163 females) were included in the analysis. The median duration of AF was 1.2 years; 11% (36/320) had paroxysmal AF. The median brain natriuretic peptide value was 623 pg/ml, and 52% of the patients (165/320) were in New York Heart Association functional class 4. During a median follow-up of 528 days, 24% (77/320) patients were observed with CDs: 2 myocardial infarctions, 51 HF-related deaths, 6 strokes, and 18 sudden cardiac deaths. At the 3-year follow-up, the survival rate by the Kaplan-Meier curve was 89% (95% confidence interval (CI) 76%-95%) in the no anemia group with high GLS (&amp;lt; -10%) and 40% (95% CI 25%-54%) in the anemia group with low GLS (≥ -10%) (p &amp;lt; 0.001, log-rank test). In multivariate Cox regression analysis, GLS (adjusted hazard ratio (aHR) 1.06, 95% CI 1.01-1.14, p = 0.017) and hemoglobin (aHR 0.85, 95% CI 0.76-0.96, p = 0.009) were independent factors for CD, with a significantly increased risk in the anemia group with low GLS compared to the no anemia group with high GLS (aHR 4.11, 95% CI 1.59-10.6, p = 0.004). The results were consistent with no interaction by gender or LVEF 50%. Conclusions Anemic patients with low GLS with AF and HF may have poor prognosis. Prospective studies are needed to determine whether iron supplementation improves prognosis in such patients.

Natural History, Phenotype Spectrum and Clinical Outcomes of Desmin (DES)-Associated Cardiomyopathy.

Pathogenic/likely pathogenic (P/LP) desmin (DES) variants cause heterogeneous cardiomyopathy and/or skeletal myopathy phenotypes. Limited data suggest a high incidence of major adverse cardiac events (MACE), including cardiac conduction disease (CCD), sustained ventricular arrhythmias (VA), and heart failure (HF) events (HF hospitalization, LVAD/cardiac transplant, HF-related death), in patients with P/LP DES variants. However, pleiotropic presentation and small cohort sizes have limited clinical phenotype and outcome characterization. We aimed to describe the natural history, phenotype spectrum, familial penetrance and outcomes in patients with P/LP DES variants through a systematic review and individual patient data meta-analysis using published reports. We searched Medline (PubMed) and Embase for studies that evaluated cardiac phenotypes in patients with P/LP DES variants. Cardiomyopathy diagnosis or occurrence of MACE were considered evidence of cardiac involvement/penetrance. Lifetime event-free survival from CCD, sustained VA, HF events, and composite MACE was assessed. Out of 4,212 screened publications, 71 met the inclusion criteria. A total of 230 patients were included (52.6% male, 52.2% probands, median age: 31 years [22.0; 42.8] at first evaluation, median follow-up: 3 years [0; 11.0]). Overall, 124 (53.9%) patients were diagnosed with cardiomyopathy, predominantly dilated cardiomyopathy (14.8%), followed by restrictive cardiomyopathy (13.5%), whereas other forms were less common: arrhythmogenic cardiomyopathy (7.0%), hypertrophic cardiomyopathy (6.1%), arrhythmogenic right ventricular cardiomyopathy (5.2%), and other forms (7.4%). Overall, 132 (57.4%) patients developed MACE, with 96 [41.7%] having CCD, 36 [15.7%] sustained VA, and 43 [18.7%] HF events. Familial penetrance of cardiac disease was 63.6% among relatives with P/LP DES variants. Male sex was associated with increased risk of sustained VA (HR 2.28, p=0.02) and HF events (HR 2.45, p=0.008). DES cardiomyopathy exhibits heterogeneous phenotypes and distinct natural history, characterized by high familial penetrance and substantial MACE burden. Male patients face higher risk of sustained VA events.

Assessment of venous congestion with venous excess ultrasound score in the prognosis of acute heart failure in the emergency department: a prospective study.

In acute decompensated heart failure (HF), systemic venous congestion contributes to patients' symptoms and hospital admissions. The purpose of our study is to determine if venous congestion, examined using the venous excess ultrasound (VExUS) score, predicts HF-related hospitalization and mortality in patients admitted to the emergency department (ED) with acute decompensated HF. Fifty patients admitted for acute HF in ED underwent ultrasound (US) assessment according to the VExUS score within the first 24 and 72 h. All patients were followed up with a telephone call at 30 and 60 days after hospital discharge. On admission, 56% had a VExUS score of 3. After 72 h, 32% had no more signs of congestion at the Doppler VExUS examination (inferior vena cava < 2 cm, VExUS score of 0); a similar percentage still exhibited a VExUS score of 3 despite therapy. Eighty per cent of patients were hospitalized after admission to the ED, while six (15%) died in-hospital; all exhibited a first-assessment VExUS score of 3. No patient with a VExUS score < 3 died during the study. During short-term follow-up, 18 patients were readmitted to the ED for acute decompensated HF. Ninety-four per cent of the readmitted patients had a VExUS score of 3 at the Doppler assessment at the first ED admission. Severe venous congestion, defined as a VExUS score of 3 at the initial assessment of patients with acute decompensated HF, predicts inpatient mortality, HF-related death, and early readmission.

Demographic trends of cardiorenal and heart failure deaths in the United States, 2011-2020.

Heart failure (HF) and kidney disease frequently co-occur, increasing mortality risk. The cardiorenal syndrome results from damage to either the heart or kidney impacting the other organ. The epidemiology of cardiorenal syndrome among the general population is incompletely characterized and despite shared risk factors with HF, differences in mortality risk across key demographics have not been well described. Thus, the primary goal of this study was to analyze annual trends in cardiorenal-related mortality, evaluate if these trends differed by age, sex, and race or ethnicity, and describe these trends against a backdrop of HF mortality. The Centers for Disease Control and Prevention Wide-ranging ONline Data for Epidemiologic Research database was used to examine cardiorenal- and HF-related mortality in the US between 2011and 2020. International Classification of Diseases, 10 Revision codes were used to classify cardiorenal-related deaths (I13.x) and HF-related deaths (I11.0, I13.0, I13.2, and I50.x), among decedents aged 15 years or older. Decedents were further stratified by age group, sex, race, or ethnicity. Crude and age-adjusted mortality rates (AAMR) per 100,000 persons were calculated. A total of 97,135 cardiorenal-related deaths and 3,453,655 HF-related deaths occurred. Cardiorenal-related mortality (AAMR, 3.26; 95% CI: 3.23-3.28) was significantly lower than HF-related mortality (AAMR, 115.7; 95% CI: 115.6-115.8). The annual percent change (APC) was greater and increased over time for cardiorenal-related mortality (2011-2015: APC, 7.1%; 95% CI: 0.7-13.9%; 2015-2020: APC, 19.7%, 95% CI: 16.3-23.2%), whereas HF-related mortality also increased over that time period, but at a consistently lower rate (2011-2020: APC, 2.4%; 95% CI: 1.7-3.1%). Mortality was highest among older and male decedents for both causes. Cardiorenal-related deaths were more common in non-Hispanic or Latino Blacks compared to Whites, but similar rates were observed for HF-related mortality. A larger proportion of cardiorenal-related deaths, compared to HF-related deaths, listed cardiorenal syndrome as the underlying cause of death (67.0% vs. 1.2%). HF-related deaths substantially outnumber cardiorenal-related deaths; however, cardiorenal-related deaths are increasing at an alarming rate with the highest burden among non-Hispanic or Latino Blacks. Continued surveillance of cardiorenal-related mortality trends is critical and future studies that contain detailed biomarker and social determinants of health information are needed to identify mechanisms underlying differences in mortality trends.
