Overview
Natural history, complications and prognosis
- Commotio cordis has a poor prognosis with only a small number of these victims surviving after immediate resuscitation. A continuous rise of survival rates due to commotio cordis is evident, shifting from 10%–15% before the year 2000 to more than 50% in 2012 l[1].
- There is a 10 percent decline in survival rate in the first minute following the loss of consciousness. Five percent decline in survival rate in each following minute following the loss of consciousness[1].
- Generally, it is assumed that if commotio cordis is successfully treated and recovered, no further heart complications will develop.
- A study demonstrated that out of the total cases of commotio cordis, 71% experienced a full physical recovery, while the remaining 29% exhibited mild to moderate residual neurological disability or cardiac impairment (noted through a decrease in left ventricular ejection fraction) during the follow-up period spanning from 1 to 20 years.
