Key result
New noninstrumental test proposed to assess diaphragmatic contractile dysfunction via neurophysiological mechanisms.
Why the study?
Cardiac surgery with median sternotomy and myocardial infarction cause diaphragmatic dysfunction that requires evaluation for therapeutic management.
This review discusses the neurophysiological relationships of the diaphragm and proposes a scientific basis for a new noninstrumental diaphragmatic test in patients recovering from cardiac events.
Diaphragm assessment merits consideration after cardiac surgery or MI; leaves open whether targeted interventions improve recovery in prospective trials.
Cardiac surgery with median sternotomy causes iatrogenic damage to the function of the diaphragm muscle that is both temporary and permanent. Myocardial infarction itself causes diaphragmatic genetic alterations, which lead the muscle to nonphysiological adaptation. The respiratory muscle area plays several roles in maintaining both physical and mental health, as well as in maximizing recovery after a cardiac event. The evaluation of the diaphragm is a fundamental step in the therapeutic process, including the use of instruments such as ultrasound, magnetic resonance imaging (MRI), and computed axial tomography (CT). This article reviews the neurophysiological relationships of the diaphragm muscle and the symptoms of diaphragmatic contractile dysfunction. The authors discuss a scientific basis for the use of a new noninstrumental diaphragmatic test in the hope of stimulating research.

Bordoni et al. (2021) conducted a review in Diaphragmatic contractile dysfunction. Noninstrumental diaphragmatic test was evaluated. This review discusses the neurophysiological relationships of the diaphragm muscle and proposes a scientific basis for a new noninstrumental diaphragmatic test to evaluate contractile dysfunction.
