The right side of the heart would fail first in the case of:
1)severe mitral valve stenosis
2)uncontrolled essential hypertension
3)large infarction in the right ventricle
4)advanced COPD

Question

Quizplus · Accepted Answer

The right side of the heart is responsible for pumping blood to the lungs for oxygenation. Advanced COPD can cause significant damage to the lungs, increasing the resistance in the pulmonary circulation and ultimately causing the right side of the heart to fail. A large infarction in the right ventricle can also lead to right heart failure. Severe mitral valve stenosis and uncontrolled essential hypertension primarily affect the left side of the heart and are unlikely to cause right heart failure as the initial presentation.
