Percutaneous coronary intervention (PCI) does not really yield advanced outcomes and conversely increases the risk of ischemia, restricted blood flow or arrhythmia, irregular heartbeat, say British researchers.

A new research has shown that there was no improvement in the health of patients who got a pump placed in their heart's aorta before undertaking some procedures to open blocked arteries.

This procedure involves stent placement or balloon angioplasty in which the pump is connected to a balloon-type device that is inserted into the descending aorta to open up the narrowed coronary arteries.

Author Dr. Divaka Perera, of King's College London asserted, "Observational studies have previously reported that elective IABP insertion may improve outcomes following high-risk PCI. To date, this assertion has not been tested in a randomized trial”.

An occurrence of a major adverse cardiac and cardiovascular event (MACCE) was discovered in a study of 301 patients. In this study while some of the patients had opted for IABP insertion, others were against it.

Death, heart attack, cerebrovascular event or further revascularization at hospital discharge for a period of 28 days, is known as MACCE. As much as 15.2% of the elective IABP group and 16% of the no-planned IABP group notably reached the primary endpoint of MACCE.
