title: Cor pulmonale in asthma.
abstract: The development of right ventricular failure due to pulmonary hypertension is a common complication of severe chronic bronchitis and emphysema (Renzetti et al. 1976) but is rare in bronchial asthma (Clark 1977). We report a 20-year-old extrinsic asthmatic with persistent hypoxaemia and carbon dioxide retention, secondary polycythaemia and cor pulmonale and describe his further investigation.
