It is now well known
that cardiac arrest survivors suffer severe emotional and mental stress. The
survivors also experience some degree of neuropsychological effects as a
consequence of some brain injury.
In order to analyze
the long-term aftermaths of cardiac arrest in survivors, Paul Chan and colleagues assessed the rates of long term survival and readmission among survivors of in-hospital cardiac arrest
and whether demographic
characteristics and neurological status affected these rates.
collected data from the registry of inpatient cardiac arrests with Medicare
files and enrolled 6972 cardiac arrest survivor adults about 65 years of age
and above. They had in-hospital cardiac arrest during 2000-2008. The experts
also examined rate of one-year survival and readmission in the hospital.
It was seen that about
58.5 percent of survivors were alive while 34.4 percent did not require
readmission in the hospital. 'The risk-adjusted rate of 1-year survival was
lower among older patients than among younger patients.'
The rate of one-year
survival was 72.8 percent in patients with mild or no neurological disability
at the time of discharge in contrast to 61.1 percent in patients with moderate
neurological disability and about 42.2 percent in people with severe
neurological disability. While patient who were in vegetative state or coma had
10.2 percent rate of one-year survival.
As far as the rate of
readmission is concerned, the scientists noted that it was high in black
females having some neurologic
disability. The researchers said that the differences in
the rates of survival and readmission lasted at two years and at third year, 'rate
of survival among survivors of in-hospital cardiac arrest was similar to that
of patients who had been hospitalized with heart failure and were discharged
finally concluded that about 60 percent of the elderly cardiac survivors were
alive for one year and the three year survival rate was almost identical to the
survival rate of heart failure. However the rate of readmission and survival
vary in accordance with the demographic condition of the patient as well as the
neurological status at the time of discharge.
The research was
financially aided by the American Heart Association and the National Heart,
Lung, and Blood Institute
and was published in New England Journal of
Long-Term Outcomes in Elderly Survivors of
In-Hospital Cardiac Arrest; Paul Chan et al; N Engl J Med 2013.
