Implication

Supports supervised exercise post-CABG to boost fitness; reinforces cardiac rehab guidelines in men.

Key Points

To assess the functional and cardiovascular effects of a one-year medically supervised exercise training regimen in male patients following coronary artery bypass surgery.
Randomized trial allocating 53 male post-bypass patients to either a medically supervised exercise program (N = 28) or usual community care (N = 25).
Participants were tested at baseline and at one year with electrocardiography, thallium scintigraphy, and maximal oxygen uptake assessments.
The exercise intervention involved three sessions weekly at 80% maximal heart rate, achieving an 82% average attendance rate with five dropouts over 12 months.
Exercising patients, including both those with and without angina, achieved significant increases in measured and estimated oxygen uptake.
Participants in the exercise cohort demonstrated significant reductions in resting and submaximal heart rates compared to baseline.
No major adverse complications occurred during the intervention, and patients with angina showed a trend toward improved thallium myocardial perfusion scans.

Structured PICO

Does a medically supervised exercise program improve oxygen uptake and heart rate in male patients after coronary artery bypass surgery?

Population

53 male volunteers who had undergone coronary artery bypass surgery, approximately one third with signs and/or symptoms of ischemia

Intervention

Medically supervised exercise program (three times a week, training at 80% of maximal heart rate) for one year

Comparator

Usual community care

Outcome

Changes in thallium scintigraphy, maximal oxygen uptake, and electrocardiography at one yearsurrogate

A medically supervised exercise program significantly improves oxygen uptake and lowers resting heart rate in men following coronary artery bypass surgery.
