Case Study Scenario
Chief Complaint
A.C., is a 61-year old male with complaints of shortness of breath.
History of Present Illness
A.C. was seen in the emergency room 1 week ago for an acute onset of mid-sternal chest pain. The event was preceded with complaints of fatigue and increasing dyspnea for 3 months, for which he did not seek care. He was evaluated by cardiology and underwent a successful and uneventful angioplasty prior to discharge. Despite the intervention, the shortness of breath has not improved. Since starting cardiac rehabilitation, he feels that his breathlessness is worse. The cardiologist has requested that you, his primary care provider, evaluate him for further work-up. Prior to today, his last visit with your practice was 3 years ago when he was seen for acute bronchitis and smoking cessation counseling.
