Mr. Aldredge, a 46-year-old building contractor, entered the hospital?s walk-in clinic with arm pain. He told the nurse on duty that lifting had always been part of his line of work. Although he was a supervisor in his job, he often helped with lifting heavy objects and would sometimes work alongside his crew to help meet a project deadline. For the last day on the job his left arm hurt intensely, and that is why he decided to come to the clinic to ?set it right.?
The nurse noticed Mr. Aldredge was substantially overweight and would sometimes pause for breath while describing his problem. The pain radiated all the way from his wrist up to his chest. Mr. Aldredge said he had never felt anything like it before. He said he had never had any heart problems?felt so healthy, in fact, that he hadn?t been to a doctor in years. He had even recently quit smoking.
The nurse cut Mr. Aldredge?s examination short to have him transported to the emergency room for prompt evaluation and treatment of a probable myocardial infarction.
