Accuracy of patient recall of pre-operative symptom severity (angina and breathlessness) at one year following coronary artery bypass grafting

The accuracy with which patients recall their cardiac symptoms prior to aorta-coronary artery bypass grafting is assessed approximately one year after surgery together with patient-related factors potentially influencing accuracy of recall. This is a novel investigation of patient’s rating of preoperative symptom severity before and approximately one year following aorta-coronary artery bypass grafting.
