Inefficient breathing affects functional movement and influences health and wellness. The purpose was to determine the physical activity and breathing pattern dysfunction in patients following a median sternotomy after the hospital and identify the factors contributing to the dysfunction.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cross\u2010sectional study, using telehealth video consultations, took place from December 2022 to November 2023, 3 months to 1 year after hospital discharge. The presence of breathing pattern dysfunction was determined using the Nijmegen Questionnaire, the Self\u2010Evaluation of Breathing Questionnaire, the Breath Hold Time test, and chest expansion evaluation. The Physical Activity Vital Sign provides information on physical activity.

Most underwent surgery for coronary artery bypass grafting (<jats:italic>n<\/jats:italic>\u2009=\u200927 [51.9%]) and spent 7 (IQR 8) days in hospital. In total, 46 (88.5%) participated in weekly aerobic exercise of a median duration of 140 (IQR 228) minutes. Only 11 (21.15%) reported strength training. Rating of breathing pattern dysfunction was Nijmegen Questionnaire 16.98 (\u00b19.76) versus Self\u2010Evaluation of Breathing Questionnaire 10.00 (IQR 12), and <jats:italic>n<\/jats:italic>\u2009=\u200920 (38.5%) and <jats:italic>n<\/jats:italic>\u2009=\u20098 (15.4%) scored positive for breathing pattern dysfunction, respectively. The mean Breath Hold Time test was 21.60 (\u00b15.94) seconds. Increasing weekly aerobic exercise was associated with the Self\u2010Evaluation of Breathing Questionnaire (<jats:italic>r<\/jats:italic>\u2009=\u2009\u22120.30, <jats:italic>p<\/jats:italic>\u2009=\u20090.03), Breath Hold Time test (<jats:italic>r<\/jats:italic>\u2009=\u20090.29, <jats:italic>p<\/jats:italic>\u2009=\u20090.04), lower chest expansion (<jats:italic>r<\/jats:italic>\u2009=\u20090.39, <jats:italic>p<\/jats:italic>\u2009=\u20090.003), and upper chest expansion (<jats:italic>r<\/jats:italic>\u2009=\u20090.33, <jats:italic>p<\/jats:italic>\u2009=\u20090.02).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Breathing pattern dysfunction is present long\u2010term and weekly participation in aerobic exercise lessens this dysfunction.
