COPD is known to cause air trapping and stiff alveoli leading to increased pulmonary pressure. When the right side of the heart tries to pump blood against this increased pressure in the lungs, it can result in:
Cor Pulmonale
Flattening of neck veins
Weight loss
Shrunken liver
The Correct Answer is A
A. Cor Pulmonale is right-sided heart failure caused by pulmonary hypertension, which is often a complication of COPD due to increased pressure in the pulmonary arteries.
B. Flattening of neck veins is associated with fluid overload, not with right-sided heart failure.
C. While weight loss can occur in COPD patients due to increased energy expenditure, it is not directly related to the development of cor pulmonale.
D. The liver might actually become enlarged due to congestion from right-sided heart failure.
