Experience with long-term nifedipine therapy in paediatric cardiological patients.
Clinical experience with long-term nifedipine treatment in 23 patients aged between 1 1/12 and 14 8/12 years is reported. The cardiopulmonary diseases comprised primary pulmonary diseases with pulmonary hypertension (n = 4), congenital heart defects with intracardiac shunts and pulmonary hypertension which either were inoperable as a result of an Eisenmenger reaction (n = 7) or presented a high surgical risk (n = 5), or defects in which pulmonary hypertension did not regress despite corrective (n = 1) or palliative surgery (n = 3), and congenital defects without pulmonary hypertension (n = 3). Subjective improvement with an increase in physical performance was clearly observed in 15 cases. Echocardiography and cardiac catheter examinations showed no progression of the pulmonary arterial diseases, except in 1 patient with severe primary pulmonary hypertension and an 11-year observation period with nifedipine treatment during the last 4 years. No complications occurred during the 4 corrective operations. A patient aged 14 8/12 years with the Down syndrome and atrioventricular septal defect developed easily controllable heart failure during 7-day administration of nifedipine without additional cardiotherapy. 4 children initially suffered from flushed face and scalp, in one case with headache; 2 children reported fatigue. Long-term treatment with nifedipine should begin with strict 7-day supervision in hospital and possibly additional digitalization. Success of the treatment was determined by an improved quality of life in patients with primary pulmonary hypertension and inoperable defects, and by a reduced perioperative risk and postoperative regression of pulmonary hypertension in patients with operable defects.
