Challenging traditional activity limits after coronary artery bypass graft surgery: a simulated lawn-mowing activity

Area of Science:

• Cardiology
• Cardiac Rehabilitation
• Post-Surgical Recovery

Background:

• Cardiac events and surgeries often lead to patient fear and inactivity.
• Physician-recommended restrictions can be overly cautious, impacting quality of life.
• Lawn mowing is frequently discouraged after coronary artery bypass surgery (CABS).

Purpose of the Study:

• To evaluate the safety of simulated lawn mowing in patients post-cardiac surgery.
• To determine if lawn mowing affects sternal incision integrity and cardiovascular parameters.
• To assess the feasibility of resuming this common activity in a supervised setting.

Main Methods:

• A 6-session simulated lawn mowing protocol was used.
• Forces mimicked those of a non-propelled outdoor mower.
• Monitoring included chest X-rays, sternal palpation, ECG, heart rate, and blood pressure.

Main Results:

• No subjects experienced adverse cardiac events or arrhythmias.
• No detrimental changes in heart rate or blood pressure were observed.
• Sternal wires remained stable, with no signs of dehiscence on radiographs.

Conclusions:

• Simulated lawn mowing is safe for patients recovering from cardiac surgery.
• The activity did not negatively impact sternal incision, ECG, blood pressure, or heart rate.
• This suggests a potential for supervised return to such activities.
