Insights
Adults with congenital heart disease (ACHD) have similar atherosclerotic cardiovascular disease (ASCVD) risk factors as the general population. Exceptions include higher diabetes mellitus rates and lower smoking rates in ACHD patients.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Adults with congenital heart disease (ACHD) face risks of atherosclerotic cardiovascular disease (ASCVD) comparable to the general population.
- These risks are primarily influenced by traditional ASCVD risk factors.
Purpose of the Study:
- To determine the prevalence of traditional ASCVD risk factors in ACHD patients.
- To compare the prevalence of these risk factors in ACHD patients with the general population.
Main Methods:
- A systematic literature search identified relevant studies up to May 15, 2024.
- Meta-analyses synthesized prevalence data and compared ACHD patients with control groups where available.
Main Results:
- The study analyzed 62 studies involving 110,469 ACHD patients.
- Prevalence rates were similar between ACHD patients and controls for hypertension, dyslipidemia, obesity, and physical inactivity.
- Notably, ACHD patients showed a higher prevalence of diabetes mellitus and a lower prevalence of smoking compared to controls.
Conclusions:
- Traditional ASCVD risk factor prevalence, excluding diabetes mellitus and smoking, is comparable between ACHD patients and the general population.
- Further research is required to ascertain the efficacy of general population interventions for ASCVD risk reduction in ACHD patients.
Background:
The risk of atherosclerotic cardiovascular disease (ASCVD) in adults with congenital heart disease (ACHD) is comparable to that of the general population and is driven by traditional ASCVD risk factors.
Objectives:
The aim of the study was to estimate the prevalence of traditional ASCVD risk factors (hypertension, dyslipidemia, diabetes mellitus [DM], obesity, smoking, and physical inactivity) in ACHD and compare it with the general population.
Methods:
A systematic literature search was conducted up to May 15, 2024, to identify studies (with or without control group) reporting the prevalence of ASCVD risk factors in ACHD. Meta-analyses were conducted to synthesize the prevalence of risk factors and compare it with that of the general population, where applicable.
Results:
We identified 62 studies (30 controlled) encompassing 110,469 ACHD (mean age 39 years; 52% males, 88% with simple/moderate congenital heart disease complexity). Of these, 54% (45%-63%) reported lack of regular exercise, 33% (26%-40%) had hypertension, 18% (14%-22%) were obese, 17% (11%-25%) had dyslipidemia, 12% (9%-14%) were current smokers, and 7% (5%-9%) had DM. The prevalence of ASCVD risk factors was similar in ACHD and controls, with the exception of DM (higher prevalence in ACHD) and smoking (lower prevalence in ACHD). Significant heterogeneity was observed among the included studies, partially explained by differences in age, congenital heart disease complexity, and the presence of cyanosis.
Conclusions:
Except for DM and smoking, the prevalence of traditional ASCVD risk factors is similar in ACHD compared to the general population. Further research is needed to determine whether interventions applied in the general population are also effective in ACHD.
