Factors influencing supply

-Coronary Blood flow
-Collateral circulation
-Distribution
-Coronary perfusion pressure
-Coronary artery disease

Factors influencing demand

-Heart rate
-LV wall stress (contractile state of the myocardium)
-Pre/After Load

Indications for IABP

-Cardiogenic shock
-Unstable angina
-Post CABG

, -PCI
-High risk patients (Multiple vessel disease, left main occlusion)

Contraindications for IABP

-Irreversible brain damage
-Dissecting thoracic aneurysm
-Aortic Insufficiency

Reasons for LV failure

-Hypertension (CAD, MI, CM)
-Excessive workload (Resistance to systolic ejection, stroke volume- AI, MI, TI, Left to right
shunt, Body demands, Drug abuse (cocaine) )

Late Deflation

-Assisted aortic end diastolic pressure may be equal to the unassisted aortic end diastolic
pressure
-Rate of rise of assisted systole is prolonged
-Diastolic augmentation may be widened

Early Deflation

-Deflation is a sharp drop following diastolic augmentation
-Sub optimal diastolic pressure may be less than or equal to the unassisted aortic end diastolic
pressure
-Assisted systolic pressure may rise

Late Inflation

-Inflation after the diacrotic notch
-Absence of a sharp V
-Sub optimal diastolic augmentation

Early Inflation

-Inflation prior to diacrotic notch
-Diastolic augmentation encroaches onto systole
