The Impact of Heart Failure Hospitalizations on Adults with Congenital Heart Disease: A Focus on Mortality, Morbidity and Resource Use

Advertisment

According to a recent study published in the Journal of the American Heart Association, adults with congenital heart disease (ACHD) who are hospitalized for heart failure (HF) face an increased risk of mortality and morbidity. This study provides valuable insights into the outcomes of HF versus non-HF hospitalizations in ACHD, demonstrating the heightened risks associated with ACHDHF hospitalizations. These patients were found to have a higher likelihood of mortality, major adverse cardiac and cerebrovascular events, and increased health resource use.

Key Findings of the Study

The study analyzed data from 26,454 unique ACHD admissions, revealing that 22% of these were hospitalized with HF. Those patients who were hospitalized due to ACHDHF were found to have increased risks in various areas. They faced higher mortality rates, were more likely to experience major adverse cardiac and cerebrovascular events, and showed higher health resource use. This included a higher rate of rehospitalization and an increased use of postacute care services.

Role of Specialist Care

One significant finding from the study was the role specialist care played in reducing mortality rates. Patients who visited a cardiology clinic within 30 days of hospital admission were associated with lower 90-day and one-year mortality rates. Highlighting the importance of specialist care in achieving optimal health outcomes among adults living with CHD, the authors of the study emphasized that such care may be the key to improving patients' health outcomes.

Further Research and Findings

In addition to this study, other research also sheds light on various aspects of heart failure in patients with ACHD. For instance, a study examining the association of echocardiographic derived pulmonary artery wedge pressure (ePAWP) with mortality, heart hospitalizations, and functional capacity in chronic systolic heart failure found that increased ePAWP was significantly associated with cardiovascular death or HF hospitalization and all-cause death or HF hospitalization. The same study also revealed a connection between ePAWP and decreased exercise capacity, as well as shorter 6-minute walk test distance.

A retrospective review aimed at assessing the risks and benefits of cardiac intervention in adults with Down syndrome (DS) found that adults with DS can undergo cardiac operation and percutaneous intervention with low morbidity and mortality risk and good long-term survival.

Rehospitalization and Heart Failure

Heart failure is a complex clinical syndrome resulting from ventricular or extracorporeal dysfunction and is considered one of the most common chronic diseases worldwide. The prevalence of heart failure is expected to increase by 25% in 2030, leading to a high economic burden and mortality rates. The main costs are related to referring and hospitalization, followed by medications and social support.

More than 50% of patients with heart failure return to the hospital within six months of discharge, making it a critical health problem. Factors such as age, duration of disease, body mass index, dyspnea, edema, high blood pressure, diabetes, chronic obstructive pulmonary disease, ischemic heart disease, high creatinine, not using beta blockers, and not taking angiotensin receptor blockers were significantly associated with re-referrals to the emergency.

The findings from these studies underscore the importance of specialist care and ongoing monitoring for patients with ACHD who are hospitalized with HF. There is a clear need for further research and a comprehensive approach to managing these patients to improve their health outcomes and quality of life.
