Pulmonary hypertension
increased pulmonary arterial pressure (pulmonary systolic pressure >30mmg)
diagnosis
most accurate is via direct pressure measures obtained by cardiac catheterisation
estimation by
doppler echocardiography
in patients with pulmonary or tricuspid valvular insufficiency
causes
obstruction of venous drainage
heart disease
increased pulmonary blood flow
congenital heart lesions
increased pulmonary vascular resistance
pulmonary thromboembolism
heart worm
chronic pulmonary parenchymal disease
canine chronic bronchitis
idiopathic pulmonary fibrosis
adaptive response of lung to improve ventilation and perfusion through hypoxic vasoconstriction
primary/idiopathic
genetic cause
