A fifty-year-old man visited his family physician for a routine checkup. He appeared to be healthy.
He complained of experiencing occasional chest pain. He said the chest discomfort was accompanied with feeling of dizziness, shortness of breath and tingling in fingers. It usually occurred during an evening walk, which he took after dinner. The chest ache lasted for a very short time and disappeared if he stopped walking for a short while.
He also mentioned that he had started taking the short evening walks recently on the advice of a friend.
