Cardiac Arrest and Resuscitation

In Brief PURPOSE Physician advice and restrictions to patients following a cardiac event can, in some instances, lead patients to be fearful regarding their activities even to the point of inactivity. The purpose of this study was to test whether lawn mowing, one of the activities most strongly discouraged after coronary artery bypass surgery, could be safely performed in a supervised setting. METHOD Subjects participated in a 6-session simulated lawn-mowing protocol, calibrated to match the push and pull forces of using an outdoor nonpropelled lawn mower. Plain chest radiographs were taken before and after the protocol period. During each session, subjects' sternums were carefully palpated and electrocardiograms, heart rates, and blood pressures were monitored. RESULTS None of the 13 subjects experienced adverse arrhythmia events or detrimental heart rate, blood pressure, or sternal palpation findings that led to study discontinuation. The radiographs taken after protocol completion showed stable sternal wires with no evidence of sternal dehiscence. CONCLUSION Simulated lawn mowing did not negatively affect the sternal incision, electrocardiogram findings, blood pressure, or heart rate in this small sample. Thirteen subjects who had undergone coronary artery bypass surgery participated in a 6-session simulated lawn-mowing protocol and were closely monitored. Performance of simulated lawn mowing did not negatively affect the sternal incision, suggesting that some activity restrictions on patients may not be as necessary as often believed.
