Heart failure its causes

• Definition
• Causes-
• 1. Coronary Artery Disease (CAD)
• 2. Hypertension
• 3. Valvular Heart Disease
• 4. Cardiomyopathy
• In addition to those causes above, the following
  factors also can play a role in determining if
  heart failure will affect you
• 1. family history of heart failure
• 2. diabetes
• 3. marked obesity
• 4. heavy consumption of alcohol, or drug
  abuse
• 5. failure to take medications
• 6. large salt intake in diet
• 7. sustained rapid heart rhythms

• Pump sucks the blood from left ventricle and
  forces it into the aorta.

About the pump

• It is 1.5 pounds,12-mm smooth titanium pump
  cradled between the inlet and outlet elbow
  connectors, lies parallel to the diaphragm has
  only one moving part, the rotor has only one
  moving part, the rotor.
• The motor is contained in the pump housing and
  creates a spinning magnetic field that spins the
  rotor and imports torque to its internal
  cylindrical magnet.
• The LVAD normally pumps at a rate of 60-80 beats
  per minute, but can increase to 120 beats per
  minute with exercise.
