Which of the following is the most likely result of increased pulmonary artery pressure?
A) Increased left ventricular workload and cor pulmonale
B) Increased right ventricular workload and cor pulmonale
C) Decreased right atrial workload and right ventricular hypertrophy
D) Increased left ventricular workload and congestive heart failure

Question

Quizplus · Accepted Answer

Increased pulmonary artery pressure is most likely to lead to an increased right ventricular workload and eventually cause right-sided heart failure, also known as cor pulmonale. This is because the right ventricle pumps blood to the lungs through the pulmonary arteries, and if these vessels are under increased pressure, the right ventricle has to work harder to push blood through them. This can eventually lead to enlargement and weakened function of the right ventricle, causing cor pulmonale.
