The purpose of this study was to determine whether pulmonary hemodynamic abnormalities relate to manifestations of allergic asthma. In 448 patients with congenital heart disease the relationships between asthma and age or pulmonary arterial blood (PA) flow were studied. Asthma (allergic and non‐allergic) was more common in 39 (19%) of 201 patients with high PA flow, compared with the incidence in those with normal PA flow (6/117, 5%; P < 0.001) and reduced PA flow (1/130, 1%; P < 0.05). In the high PA flow group, the frequency of asthma declined significantly ( P < 0.01) with age, from 25–26% in the 6 month‐5 year patient group to 5% in the 6–12 year old patients. The frequency of asthma, including allergic type, was significantly ( P < 0.01) greater in patients with pulmonary hypertension (15/24, 63%) than in those without (10/77, 13%) at the age of 6 months to 1 year. Asthma in the high PA flow group was associated with other allergic diseases in 30 (77%) of 39 patients, including food allergy in nine (23%), atopic dermatitis in 14 (36%), allergic rhinitis in seven (18%) and abnormally high total IgE levels in 14 (36%). These findings suggest that high pulmonary flow or pulmonary hypertension enhances the manifestation of allergic disease, particularly asthma.
