Problem
"I have been experiencing chest pain for the past couple of weeks, unlike any I've felt before. I am also tired most of the time and have lost my appetite." 62 y/o male patient has a recent history of mild chest pain, shortness of breath, and malaise. No murmur has yet been reported. The patient says he underwent tooth extractions a month ago and had been given antibiotics by the dentist, but since he wasn't feeling ill, he did not take them. Patient reports his father died at 79 y/o due to CHF.
a) What complaints support the diagnosis?
b) Why is the patient history an important part of this diagnosis?
c) What is the meaning of the abbreviation CHF?
