Question:

Congestion of the lungs is one of the main symptoms in:

Options:

1. Hypotension
2. Coronary artery disease
3. Angina
4. Heart failure

Solution:

Congestion of the lungs is a common symptom in heart failure. In heart failure, the heart is not able to pump blood effectively, causing blood to back up in the veins, which can lead to fluid accumulation in the lungs, causing congestion. Hypotension is low blood pressure, which may cause lightheadedness or dizziness. Coronary artery disease and angina are conditions that involve the blockage or narrowing of the blood vessels that supply the heart with blood and oxygen, which can cause chest pain or discomfort, but they are not typically associated with lung congestion as a primary symptom.
