What is one of the primary goals of IABP therapy regarding coronary artery perfusion?

One of the primary goals of Intra-Aortic Balloon Pump (IABP) therapy is to increase diastolic pressure in the aorta. By inflating the balloon during diastole, IABP therapy enhances aortic diastolic pressure, which subsequently improves coronary perfusion. This is particularly important in patients experiencing acute coronary syndrome or other forms of cardiac dysfunction, as it allows for better oxygen delivery to the myocardial tissue when the heart is in its resting phase between contractions.

The increase in diastolic pressure can help sustain adequate blood flow through the coronary arteries, especially in scenarios of compromised heart function. Enhancing diastolic pressure can lead to improved myocardial oxygen supply and reduced ischemia. This therapeutic effect is crucial for stabilizing patients and potentially recovering myocardial tissue that may be under stress due to inadequate perfusion.
