Heart Failure 4: Patofisiology

Patofisiologi heart failure can be better understood with attention to two important components that play a role:
a. Abnormalities miokard primary cause of the heart pumps disfungsi power.
b. Congestive heart failed due to a primary disfungsi heart, as a response from a variety of excessive work load (overload). When the overload is caused by hypertension or pressure diastolic that escalate, there will be a hypertrophy cells heart muscle (miosit) that seeks to normal-burden on the muscle cells. This overload can also occur due to the loss of part of network miokard the remaining miokard who live to work excessive. The loss of part miokard this can be segmental (eg, in the heart infark), or focal and diffuse (for example, in some types of cardiomiopati). In the circumstances this can also occur hypertrophy cells miosit (Suryadipraja, 1996).
