Insights
Adults with congenital heart defects face increased cardiovascular risks, including coronary artery disease. Lifestyle factors and specific defect types heighten this risk, necessitating a focus on long-term prevention and management.
Area of Science:
- Cardiology
- Adult Congenital Heart Disease
Background:
- Improved survival rates for congenital heart defects lead to a growing adult population.
- Adults with congenital heart defects (ACHD) experience increased cardiovascular morbidity.
- Conventional coronary artery disease (CAD) risk factors are prevalent or elevated in ACHD patients.
Purpose of the Study:
- To highlight the rising incidence of cardiovascular disease in adults with congenital heart defects.
- To emphasize the importance of addressing long-term morbidity and cardiovascular disease prevention in ACHD care.
Main Methods:
- Review of existing literature on cardiovascular risk factors in ACHD.
- Analysis of the prevalence of coronary artery disease in various congenital heart defect populations.
- Comparison of risk factors and outcomes between ACHD patients and the general population.
Main Results:
- Coronary artery disease is a significant cause of mortality in ACHD patients.
- Obesity and sedentary lifestyles are more common in ACHD patients.
- Specific conditions like coarctation of the aorta and post-operative states increase CAD risk.
Conclusions:
- A paradigm shift is needed from focusing on operative mortality to long-term morbidity and prevention.
- Cardiovascular disease prevention strategies must be integrated into routine follow-up care for ACHD patients.
- Proactive management of cardiovascular risk factors is crucial for improving long-term outcomes in ACHD.
Abstract:
The prognosis of patients with congenital heart defects has improved significantly: more and more patients reach adulthood and old age. At the same time, the possibility of cardiovascular morbidity increases. The conventional risk factors for coronary artery disease are at least as high or even higher in patients than in the general population. Obesity and sedentary life style are more common in adults with congenital heart defect (ACHD) than in general population. In some patients, for example those with coarctation of the aorta or patients with operated coronary arteries in the infancy, the incidence of coronary artery disease (CAD) is clearly increased. In some patients with cyanotic heart defects (e.g. Fontan), the incidence of CAD might be lower, but it usually returns to the average level or higher after correction of the defect. Coronary artery disease is one of the most important reasons for mortality also in ACHD patients, and the consequences of a coronary event might be more fateful in a patient with a corrected congenital heart defect than in her/his peer. There should be a paradigm shift from operative mortality and short-term outcome to long-term morbidity and prevention of cardiovascular disease - a task that often has been forgotten during follow-up visits.
