IABP can be used to provide support during which procedures?

• A. Coronary angiography, coronary angioplasty, thrombolytic therapy, high-risk interventional procedures
• B. Routine physical therapy
• C. Liver biopsy
• D. Pulmonary function testing

Answer: (A)

IABP provides hemodynamic support by inflating during diastole to boost coronary perfusion and deflating just before systole to reduce afterload, thereby helping maintain cardiac output during stressful or high-risk situations. This is why it’s used to support patients undergoing coronary angiography and coronary angioplasty, during thrombolytic therapy for myocardial infarction, and in high‑risk interventional procedures where the heart may not tolerate the stress. The other options don’t involve procedures that typically compromise hemodynamics in a way that requires circulatory support, so routine physical therapy, liver biopsy, and pulmonary function testing aren’t indications for IABP.
