How does prostacyclin therapy reduce the pathologic problems of primary pulmonary hypertension?
A. Increasing lung blood flow by dilating pulmonary blood vessels
B. Improving ventilation by increasing the contractility of the diaphragm
C. Increasing gas exchange by changing the elasticity of the alveolar walls
D. Protecting the heart from development of cor pulmonale by increasing cardiac muscle strength
A
Primary pulmonary hypertension is the increased vascular resistance in pulmonary blood vessels, making blood flow through these vessels more difficult. The right side of the heart has to pump harder to move blood through these pulmonary vessels. The extra work of the heart causes right-sided cardiac hypertrophy and eventually failure. Continuous delivery of systemic prosta-cyclin keeps the smooth muscle of pulmonary blood vessels in a more relaxed state, improving blood flow through these vessels with relatively weak right-sided cardiac muscle strength.
