Key result
A 4-week intensive exercise training program increased mean exercise capacity from 46.7 to 69.5 kJ (P=0.0001), with five clinical variables including infarct size predicting the training effect.

Population
105 patients, 68 years old or younger, starting 5 weeks after qualifying myocardial infarction

Do simple clinical variables predict the effect of intensive exercise training in patients early after myocardial infarction?
Absolute Event Rate: 69.5% vs 46.7%
p-value: p=0.0001
Five simple clinical variables, including infarct size, age, gender, baseline exercise capacity, and beta-blocker use, can help predict which patients will derive the most benefit from intensive exercise training early after myocardial infarction.
Heldal et al. (1996) conducted an observational in myocardial infarction (n=105). Intensive exercise training was evaluated on absolute increase in cumulative work at bicycle ergometry (p=0.0001). A 4-week intensive exercise training program increased mean exercise capacity from 46.7 to 69.5 kJ (P=0.0001), with five clinical variables including infarct size predicting the training effect.
