Who is most at risk for cardiac arrest?

Men are more likely than women to have SCA. Some studies show that blacks—particularly those with underlying conditions such as diabetes, high blood pressure, heart failure, and chronic kidney disease or certain cardiac findings on tests such as an electrocardiogram—have a higher risk for SCA.

Can you fully recover from a cardiac arrest?

Cardiac arrest is a devastating event. Despite improving resuscitation practices, mortality for those who suffer an out-of-hospital cardiac arrest (OHCA) is >90% with many survivors being left with severe neurological impairment. However, some do make a good recovery and return home to a meaningful quality of life.

Can you live after cardiac arrest?

Most people who experience cardiac arrest do not survive. Among those who do, there is risk of neurologic dysfunction, brain injury, disorders of consciousness, neurocognitive deficits, changes in quality of life, as well as physical and psychological wellbeing.

How does a cardiac arrest feel?

Usually, the first sign of sudden cardiac arrest (SCA) is loss of consciousness (fainting). At the same time, no heartbeat (or pulse) can be felt. Some people may have a racing heartbeat or feel dizzy or lightheaded just before they faint.

What happens immediately after death?

Decomposition begins several minutes after death with a process called autolysis, or self-digestion. Soon after the heart stops beating, cells become deprived of oxygen, and their acidity increases as the toxic by-products of chemical reactions begin to accumulate inside them.

What is the quality of life after cardiac arrest?

Conclusions: When evaluated with EQ-5D at 6-months after ICU discharge, survivors of cardiac arrest exhibit a HR-QOL similar to other ICU survivors. These results agree with previous reports stating that CPR is frequently unsuccessful but if survival is achieved a fairly good quality of life can be expected.

How long do you stay in the hospital after a cardiac arrest?
