The patient followed the doctor's advice. He started a low fat diet. He also joined a health club and started exercising regularly. He changed his work habits and stopped taking work home. He started meditation and biofeedback therapy. He monitored his lipids every six months.
After one year, his lipid levels were reduced significantly. By the end of second year there was a slight weight loss and there were no abnormal laboratory tests. By the end of third year of regular exercise, low fat diet, and stress reduction techniques, there was no further evidence of chest pain.
In this case the patient's condition was diagnosed by identifying the risk factors by laboratory testing. The clinician could then treat the patient effectively by correcting the biochemical abnormalities identified by laboratory testing. Patient compliance and follow up also play important roles in the successful management of the risk factors and disease prevention.
