Smoking status at the time of acute myocardial infarction and subsequent prognosis.

abstract：BACKGROUND:Physical activity and symptom questionnaires have been used as surrogates for exercise testing to estimate a patient's functional capacity and to individualize an exercise testing protocol in accordance with exercise testing guidelines. To validate these approaches, they must be compared with measured oxygen...
