Lifetime risk of comorbidity in patients with simple congenital heart disease: a Danish nationwide study

Interatrial Wall Abnormality is Associated with Adverse Same-Admission Outcomes Following Total Knee Arthroplasty

Total knee arthroplasty (TKA) is the most common joint arthroplasty procedure and is shown to be a reliable and efficacious way to improve quality of life. Individuals with interatrial wall abnormalities (IAWAs), such as atrial septal defect or patent foramen ovale (PFO), are at increased baseline risk for stroke and overall lifetime morbidity. The purpose of our study was to elucidate the association between IAWAs and perioperative TKA outcomes.We performed a retrospective cohort study utilizing the Healthcare Cost and Utilization Project National Inpatient Sample database. Admissions for TKA between 2010 and 2019 were identified using the international classification of disease (ICD)-9 and ICD-10 procedure codes. Patients with ICD-9-clinical modification (CM) diagnosis code 7455 or ICD-10-CM diagnosis code Q211 were assigned to the IAWA cohort, the primary exposure. Confounding variables included basic demographics, baseline health status, and surgical facility characteristics. The primary outcomes studied were medical complications, implant-related complications, and admission mortality. Univariate and adjusted multivariable regression analyses were used to identify associations.Compared to patients in the non-IAWA cohort, those in the IAWA cohort had significant risks for same-admission medical complications (odds ratio [OR] 5.77, 95% confidence interval [CI] 4.59-7.15; p < 0.001), implant-related complications (OR 1.55, 95% CI 1.09-2.12; p = 0.009), stroke (OR 77.46, 95% CI 58.4-101.2; p < 0.001), venous thromboembolism (VTE; OR 3.78 95% CI 2.47-5.51; p < 0.001), and mortality (OR 8.36, 95% CI 3.54-16.52; p < 0.001) following TKA.Compared to patients without IAWAs, those with IAWAs who undergo TKA have higher risks for same-admission medical and implant-related complications as well as same-admission mortality. Similarly, these patients have higher risks for same-admission stroke and VTE. Further research on perioperative TKA management in patients with IAWAs is needed.Level of Evidence is III: retrospective cohort study.

What does good care look like to people living with congenital heart disease in the 21st century? Qualitative online, asynchronous discussion forums

OBJECTIVES

As part of a wider study, our aim was to elicit perspectives of people with congenital heart disease (CHD) and/or their parents/carers about their experiences of healthcare and what is important to them when receiving care.

DESIGN AND SETTING

A qualitative study involving a series of closed, asynchronous, online discussion forums underpinned by an interpretivist framework and set up and moderated by three patient charities via their Facebook pages.

PARTICIPANTS

People with CHD and parents/carers of people with CHD from the UK.

RESULTS

Five forums were run for 12-24 weeks across the three charities, and 343 participants signed up to the forums. Four linked themes related to processes of care were identified following thematic analysis of the transcripts: relationships and communication; access and coordination; experience of discrete episodes of care and psychological support. These impacted how care was experienced and, for some patients, outcomes of CHD and its treatment as well as broader health outcomes. In addition, context relating to stages of the patient journey was described, together with patient-related factors such as patients' knowledge and expertise in their own condition.

CONCLUSIONS

People with CHD and their parents/carers want individualised, person-centred care delivered within an appropriately resourced, multidisciplinary service. Although examples of excellent care were provided it is evident that, from the perspective of patients and parents/carers, some National Health Service Standards for people with CHD were not being met.

Cardiac rehabilitation and adverse events among adult patients with simple congenital heart disease and heart failure

Aims

Improved care has resulted in prolonged survival of patients with congenital heart disease (ConHD), increasing age-related cardiovascular comorbidities. Although cardiovascular rehabilitation (CR) represents evidence-based care for heart failure (HF), the clinical impact of CR in patients with ConHD who developed HF during adulthood is unclear. We investigated 12-month mortality and morbidity in patients with simple ConHD diagnosed with HF with CR versus without CR.

Methods

A retrospective cohort study was conducted for the time period February 2004 - February 2024. Utilizing TriNetX, a global federated health research network, a real-world dataset of simple ConHD patients was acquired to compare patients with vs. without (controls) prescription for exercise-based CR. Patients were propensity-score matched for age, sex, ethnicity, comorbidities, procedures, and medication. The primary outcome was a composite of all-cause mortality, ischemic stroke, and acute coronary syndrome (major adverse cardiovascular events; MACE) within 12 months.

Results

Following propensity score matching, the total cohort consisted of 6,866 simple ConHD patients with HF. CR was associated with significantly lower odds for MACE (odds ratio (OR) 0.61 [95 % confidence interval (CI): 0.54-0.69]) and its individual components all-cause mortality (OR 0.40 [95 % CI 0.33-0.47]) and ischemic stroke (OR 0.75 [95 % CI 0.64-0.88]), but not acute coronary syndrome (OR 1.24 [95 % CI 0.91-1.69]).

Conclusion

CR was associated with significantly lower 12-month MACE in patients with simple ConHD with concomitant HF compared to usual care.

Study on the trend of congenital heart disease inpatient costs and its influencing factors in economically underdeveloped areas of China, 2015-2020: a case study of Gansu Province

Background

Economic data on congenital heart disease are scarce in economically underdeveloped areas of China. Therefore, this study aimed to shed light on the level and changing trend of congenital heart disease inpatients' economic burden in underdeveloped areas.

Method

This study used a multi-stage stratified cluster sampling method to select 11,055 inpatients with congenital heart disease from 197 medical and health institutions in Gansu Province. Their medical records and expenses were obtained from the Hospital Information System. Univariate analysis was conducted using the rank sum test and Spearman rank correlation. Quantile regression and random forest were used to analyze the influencing factors.

Results

From 2015 to 2020, the average length of stay for congenital heart disease patients in Gansu Province was 10.09 days, with an average inpatient cost of USD 3,274.57. During this period, the average inpatient costs per time increased from USD 3,214.85 to USD 3,403.41, while the average daily inpatient costs increased from USD 330.05 to USD 376.56. The average out-of-pocket costs per time decreased from USD 2,305.96 to USD 754.77. The main factors that affected the inpatient costs included length of stay, cardiac procedure, proportion of medications, age, and hospital level.

Conclusion

Congenital heart disease causes a significant economic burden on both families and society. Therefore, to further reduce the patient's financial burden, the length of stay should be reasonably reduced, and the rational distribution of medical resources should be continuously promoted to ensure equitable access to healthcare services.

Trends in Unplanned Admissions of Patients With Adult Congenital Heart Disease Based on the Japanese Registry of All Cardiac and Vascular Diseases-Diagnosis Procedure Combination Study

BACKGROUND

The prevalence of adult congenital heart disease (ACHD) is increasing rapidly and in particular, patients who underwent complicated surgeries are reaching their youth and middle age. Therefore, the need for ACHD treatment will increase, but the current medical situation is unknown. In this study we assessed trends in unplanned admissions in patients with ACHD in Japan.

METHODS AND RESULTS

From the Japanese Registry of All Cardiac and Vascular Diseases-Diagnosis Procedure Combination, a nationwide claim-based database, we selected patients aged >15 years with CHD defined by the International Classification of Diseases, 10th Revision codes. We identified 39,676 admissions between April 2012 and March 2018; 10,444 (26.3%) were unplanned. Main diagnoses were categorized into 3 degrees of complexity (severe, moderate, and mild) and other. Among unplanned admissions, the proportion of the severe group increased with time. Patients in the mild group were significantly older than those in the moderate and severe groups (median age: 70.0, 39.0, and 32.0 years, respectively). There were 765 deaths during hospitalization (overall mortality rate, 7.3%). The odds ratio of death during admission was significantly higher in patients aged >50 years, especially in the moderate group.

CONCLUSIONS

Patients with moderate or severe ACHD tended to experience unplanned admissions at a younger age. In anticipation of greater numbers of new, severe patients, we need to prepare for their increasing medical demands.

Biological Age in Congenital Heart Disease-Exploring the Ticking Clock

Over the past 50 years, there has been a major shift in age distribution of patients with congenital heart disease (CHD) thanks to significant advancements in medical and surgical treatment. Patients with CHD are, however, never cured and face unique challenges throughout their lives. In this review, we discuss the growing data suggesting accelerated aging in this population. Adults with CHD are more often and at a younger age confronted with age-related cardiovascular complications such as heart failure, arrhythmia, and coronary artery disease. These can be related to the original birth defect, complications of correction, or any residual defects. In addition, and less deductively, more systemic age-related complications are seen earlier, such as renal dysfunction, lung disease, dementia, stroke, and cancer. The occurrence of these complications at a younger age makes it imperative to further map out the aging process in patients across the spectrum of CHD. We review potential feasible markers to determine biological age and provide an overview of the current data. We provide evidence for an unmet need to further examine the aging paradigm as this stresses the higher need for care and follow-up in this unique, newly aging population. We end by exploring potential approaches to improve lifespan care.

Acquired cardiovascular disease in adults with congenital heart disease

Rates of successful surgical repair and life expectancy for patients with congenital heart disease have increased dramatically in recent decades. Thanks to advances in diagnosis, treatment, and follow-up care, an ever-increasing number of individuals with congenital heart disease are reaching advanced age. The exposure to cardiovascular risk factors during their lifetime is modifying the outlook and late clinical trajectory of adult congenital heart disease (ACHD). Their disease burden is shifting from congenital to acquired, primarily atherosclerotic cardiovascular disease (ASCVD) with worrisome consequences. In addition, the complex background of ACHD often curbs appropriate preventive strategies by general practitioners or adult cardiologists. Comprehensive guidance for the prevention and management of acquired heart disease in ACHD patients is currently not available, as this topic has not been covered by the European Society of Cardiology (ESC) guidelines on cardiovascular disease prevention or the ESC guidelines for the management of ACHD. In this document, a state-of-the-art overview of acquired heart disease in ACHD patients and guidance on ASCVD prevention for both ACHD specialists and non-ACHD cardiologists are provided. The aim is to provide a clinical consensus statement to foster the development of a sustainable strategy for the prevention of ASCVD in a practical and simple-to-follow way in this ever-growing cardiovascular cohort, thus reducing their cardiovascular burden.

Psychiatric co-morbidity in children and adolescents with CHDs: a systematic review

The population of long-term survivors with CHDs is increasing due to better diagnostics and treatment. This has revealed many co-morbidities including different neurocognitive difficulties. However, the prevalence of psychiatric disorders among children and adolescents and the specific types of disorders they may experience are unclear. We systematically reviewed the existing literature, where psychiatric diagnoses or psychiatric symptoms were investigated in children and adolescents (age: 2-18 aged) with CHDs and compared them with a heart-healthy control group or normative data. The searches were done in the three databases PubMed, psychINFO, and Embase. We included 20 articles reporting on 8035 unique patients with CHDs. Fourteen articles repoted on psychological symptoms, four reported on psychiatric diagnoses, and two reported on both symptoms and diagnoses. We found that children and adolescents with a CHD had a higher prevalence of attention deficit hyperactivity disorder (ranging between 1.4 and 9 times higher) and autism (ranging between 1.8 and 5 times higher) than controls, but inconsistent results regarding depression and anxiety.

Outcomes of out-of-hospital cardiac arrest in adult congenital heart disease: a Danish nationwide study

AIMS

The risk, characteristics, and outcome of out-of-hospital cardiac arrest (OHCA) in patients with congenital heart disease (CHD) remain scarcely investigated.

METHODS AND RESULTS

An epidemiological registry-based study was conducted. Using time-dependent Cox regression models fitted with a nested case-control design, hazard ratios (HRs) with 95% confidence intervals of OHCA of presumed cardiac cause (2001-19) associated with simple, moderate, and severe CHD were calculated. Moreover, using multiple logistic regression, we investigated the association between pre-hospital OHCA characteristics and 30-day survival and compared 30-day survival in OHCA patients with and without CHD. Overall, 43 967 cases (105 with simple, 144 with moderate, and 53 with severe CHD) and 219 772 controls (median age 72 years, 68.2% male) were identified. Any type of CHD was found to be associated with higher rates of OHCA compared with the background population [simple CHD: HR 1.37 (1.08-1.70); moderate CHD: HR 1.64 (1.36-1.99); and severe CHD: HR 4.36 (3.01-6.30)]. Pre-hospital cardiopulmonary resuscitation and defibrillation were both associated with improved 30-day survival in patients with CHD, regardless of CHD severity. Among patients with OHCA, simple, moderate, and severe CHD had a similar likelihood of 30-day survival compared with no CHD [odds ratio 0.95 (0.53-1.69), 0.70 (0.43-1.14), and 0.68 (0.33-1.57), respectively].

CONCLUSION

A higher risk of OHCA was found throughout the spectrum of CHD. Patients with and without CHD showed the same 30-day survival, which relies on the pre-hospital chain of survival, namely cardiopulmonary resuscitation and defibrillation.

Survival From Birth Until Young Adulthood Among Individuals With Congenital Heart Defects: CH STRONG

BACKGROUND

Limited population-based information is available on long-term survival of US individuals with congenital heart defects (CHDs). Therefore, we assessed patterns in survival from birth until young adulthood (ie, 35 years of age) and associated factors among a population-based sample of US individuals with CHDs.

METHODS

Individuals born between 1980 and 1997 with CHDs identified in 3 US birth defect surveillance systems were linked to death records through 2015 to identify those deceased and the year of their death. Kaplan-Meier survival curves, adjusted risk ratios (aRRs) for infant mortality (ie, death during the first year of life), and Cox proportional hazard ratios for survival after the first year of life (aHRs) were used to estimate the probability of survival and associated factors. Standardized mortality ratios compared infant mortality, >1-year mortality, >10-year mortality, and >20-year mortality among individuals with CHDs with general population estimates.

RESULTS

Among 11 695 individuals with CHDs, the probability of survival to 35 years of age was 81.4% overall, 86.5% among those without co-occurring noncardiac anomalies, and 92.8% among those who survived the first year of life. Characteristics associated with both infant mortality and reduced survival after the first year of life, respectively, included severe CHDs (aRR=4.08; aHR=3.18), genetic syndromes (aRR=1.83; aHR=3.06) or other noncardiac anomalies (aRR=1.54; aHR=2.53), low birth weight (aRR=1.70; aHR=1.29), and Hispanic (aRR=1.27; aHR=1.42) or non-Hispanic Black (aRR=1.43; aHR=1.80) maternal race and ethnicity. Individuals with CHDs had higher infant mortality (standardized mortality ratio=10.17), >1-year mortality (standardized mortality ratio=3.29), and >10-year and >20-year mortality (both standardized mortality ratios ≈1.5) than the general population; however, after excluding those with noncardiac anomalies, >1-year mortality for those with nonsevere CHDs and >10-year and >20-year mortality for those with any CHD were similar to the general population.

CONCLUSIONS

Eight in 10 individuals with CHDs born between1980 and 1997 survived to 35 years of age, with disparities by CHD severity, noncardiac anomalies, birth weight, and maternal race and ethnicity. Among individuals without noncardiac anomalies, those with nonsevere CHDs experienced similar mortality between 1 and 35 years of age as in the general population, and those with any CHD experienced similar mortality between 10 and 35 years of age as in the general population.

Atrial Fibrillation in Adult Congenital Heart Increase Ischemic Stroke Risk Even at Low CHA2DS2-VASc Score

Background

The population of adults with congenital heart diseases (ACHDs) is expanding, and atrial fibrillation (AF) emerges as a crucial risk factor for ischemic stroke. However, the evidence regarding the impact of AF on the incidence of ischemic stroke in ACHDs remains limited. In this study, we aimed to investigate the prevalence and effect of AF among ACHDs and assess the suitability of the traditional CHA₂DS₂-VASc score in this specific population.

Methods

Data of ACHDs from 2000 to 2010 were retrospectively collected from the Taiwan National Health Insurance Research Database. We divided ACHDs into those with and without AF, and ischemic stroke incidence was studied among ACHD subtypes and those who received anticoagulant therapy with warfarin or not according to CHA₂DS₂-VASc score.

Results

36,530 ACHDs were retrieved from the database. ACHDs had a 4.7-15.3 times higher AF risk than did the general population, which varied based on the age group. ACHDs with AF had 1.45 times higher ischemic stroke risk than those without AF (p = 0.009). Ischemic stroke incidence among ACHDs with AF aged < 50 years was 1.46 times higher than those without AF (p = 0.207). Ischemic stroke incidence was over 1.47% even in those with a low CHA₂DS₂-VASc score (0-1) with or without anticoagulant therapy.

Conclusions

During the 12-year follow-up, ACHDs with AF were found to have an increased risk of ischemic stroke. The ischemic stroke incidence was high, even in those with a low CHA₂DS₂-VASc score (0-1).
