pulmonary hypertension: explain how lung disease may lead to pulmonary hypertension and changes in cardiac ventricular morphology
1
Q
effect of pulmonary hypoxic vasoconstriction in COPD
A
reduced alveolar ventilation and air trapping means all lung vessels constrict, leading to pulmonary hypertension, causing backlog in pulmonary arteries, causing right ventricular hypertrophy (cor pulmonale) and congestive heart failure
