USMLE Step 1 cases | Cardiology: Case 14
A 65-year-old woman with a 60-pack-year smoking history comes to her primary care physician after 3 months of shortness of breath and dry cough. Until recently, she was able to walk the four blocks to her local grocery store without shortness of breath; however, now she is able to walk only one block before having to stop and rest. She has been waking from sleep with difficulty breathing and feels uncomfortable lying flat in bed. Her physical examination is notable for crackles at the lung bases. There is no evidence of hepatosplenomegaly or jugular venous distention.
