Final answer:
Intra-Aortic Balloon Pump (IABP) therapy increases coronary blood flow by assisting the heart's pumping action and reducing the workload on the heart. A balloon catheter is inserted into the aorta, and the balloon is inflated and deflated in sync with the patient's heartbeat.
Step-by-step explanation:
Intra-Aortic Balloon Pump (IABP) therapy aims to increase coronary blood flow by assisting the heart's pumping action and reducing the workload on the heart. It involves inserting a balloon catheter into the aorta, which is the main artery that carries blood away from the heart. The balloon is then inflated and deflated in sync with the patient's heartbeat, which helps to increase blood flow to the coronary arteries.
