Abstract

Early intervention to prevent premature mortality is vital for adults with congenital heart defects (CHD). Anatomic complexity and comorbid conditions are thought to contribute to CHD mortality. Since hypertension (HTN) and heart failure (HF) are the comorbid conditions among the most prevalent causes of death in the United States, and commonly accompany CHD, it is crucial to evaluate whether they are reliable predictors of mortality for adults with CHD (ACHD) independent of anatomic CHD complexity. A retrospective cross-sectional analysis of ACHD, aged 18–64, with concomitant HTN and/or HF and at least one health care encounter during 2008–2010 were assessed. Of 5,397 ACHD patients (18.3% HTN without HF, 4.4% HF without HTN, 8.3% with both), 3.0% died (n = 163) during the study period. Overall, the sample was 45.1% white, 61.4% female, and 29.0% had a complex CHD. Among those who died, 23.3% had HTN without HF, 17.2% had HF without HTN, and 42.3% had both. Crude analyses revealed that older age, male gender, black race, and having public health insurance were associated with increased mortality during the three-year study period compared to ACHD patients who were younger, female gender, white race, and covered by private health insurance. ACHD patients diagnosed with non-complex CHD lesions (i.e., shunts, valves, or shunts + valves) were at greater risk of dying compared to those with severe complex CHDs. When CHD type was assessed separately, those with valve lesions were more likely to die compared to those with complex CHD lesions. After adjustment for age, gender, race, insurance and CHD complexity, ACHD patients with HF, with or without HTN, were equally likely to die during the study period. However, ACHD patients with HF, without or without HTN, who had valve defects were more likely to die during the three-year study period compared to patients with complex CHDs.
