"My Doctor Said I Have Cor Pul-Something,which Is a Heart

"My doctor said I have cor pul-something,which is a heart problem," says Mr.Garabedian."I thought I just had these bad lungs that can't be fixed.How can that make my heart go bad?" Which mechanism leads to the development of cor pulmonale,which should serve as the basis for your response to Mr.Garabedian?

A) Left ventricular failure causes pulmonary venous congestion and pulmonary edema.
B) Pneumothorax causes compression atelectasis, decreased alveolar ventilation, and impaired oxygenation.
C) Increased resistance to pulmonary arterial flow leads to compensatory right ventricular hypertrophy.
D) Impaired ventilation causes decreased PaO₂, which precipitates cardiac dysrhythmias.
