cardiac decompensation

a condition of congestive heart failure in which the heart is unable to ensure adequate cellular perfusion in all parts of the body without assistance. Causes may include myocardial infarction, increased workload, infection, toxins, or defective heart valves.


failure of compensation.

cardiac decompensation
inability of the heart to maintain adequate circulation; it is marked by dyspnea, venous engorgement, cyanosis and edema.

Cardiac decompensation during an ischemic event weakens the predictive power of myocardial injury markers.
Once intracardiac injury is detected, early surgical repair is recommended to prevent cardiac decompensation and endocarditis (3, 4).
Early surgical repair has some advantages such as; prevention of cardiac decompensation, decrease of the risk for endocarditis, prevention of excessive adhesions which makes it difficult for reoperations, correction of a simple laceration easily beside repairing a long fistula tract, prevention of outpatient follow-up loss, and prevention of frequent patient follow up for determining the next operation's timing (3, 8).
These events may precipitate late cardiac decompensation.
1,2) These hormones affect the cardiovascular and gastrointestinal systems in particular, with the former being life threatening because cardiac decompensation frequently occurs in longstanding thyrotoxicosis, even without any underlying cardiac disease.
This causes sometimes complications like cardiac decompensation or disturbances of the circular system, which cannot be handled any more by ophthalmologists.
With the Heart Failure Monitor and new Thoracic Impedance Trend Chart, physicians have access to important diagnostic information that may help to prevent emergency hospitalization of heart failure patients by allowing intervention to occur prior to cardiac decompensation.
Chronically treated CHF patients typically need to excrete between 150mEq and 200mEq of sodium per day to prevent water retention weight gain that can eventually lead to cardiac decompensation.
