Document Summary
Caused by weakened heart muscle; hf is when the ventricles are not able to pump enough blood to meet the body"s metabolic demands. Myocardium is weakened and heart can"t eject blood. Hf can occur in the left, right sides or both. Left side hf (ie. congestive heart failure ) means = excess blood is accumulating in left ventricle - left ventricle wall hypertrophies (thickens) in compensation. Blood can back up into the lungs leading to sob and cough. Right side hf = blood backs up into peripheral veins leading to peripheral edema and organ engorgement. **lo1** - major diseases related with heart failure include: Mitral stenosis - narrowing of mitral valve of heart. Myocardial infarction - heart attack - decreased blood flow to part of heart leading to damaged myocardium. Treatment goals for hf: prevent/remove underlying causes, treat symptoms and improve quality of life. Right side of heart receives blood from venous system, pumps it into lungs where blood.
