Switching to a stronger heart pump after heart attack
Part of Heart & circulation clinical trials.
This trial tests whether switching to a more powerful heart pump (Impella 5.5) within 24 hours of a heart attack helps people whose hearts are still struggling despite a standard pump. It may be an option for patients who had a heart attack, received an Impella CP pump, but still need strong medication to keep blood flowing.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 77 years old.
- You had a heart attack caused by a blocked artery and received a temporary heart pump (Impella CP) during the procedure to open the blockage.
- After the procedure, you still had low blood pressure or needed medicine to support your blood pressure.
- A blood test during the procedure showed a lactate level greater than 2.5, meaning your body was not getting enough oxygen.
- Your heart's main pumping chamber (left ventricle) is pumping less than 45% of normal strength.
- Your doctor decides within 6 hours after the procedure that you need a stronger heart pump (Impella 5.5), and the switch happens within 24 hours.

This study examines detailed data from patients who received an Impella 5.5 heart pump to treat cardiogenic shock—a life-threatening condition where the heart cannot pump enough blood. Researchers use advanced computer analysis to understand what helps patients recover best.
This trial studies whether doctors can safely reduce heart and blood-pressure support sooner in people with severe heart failure “shock.” It may help avoid side effects of strong medicines/devices while keeping the body’s organs well supported.
This study is for people in the intensive care unit who are using a heart pump called Impella. It will collect information about how well the heart pumps blood during treatment to help doctors learn more.
This trial is testing whether using a special heart pump (PulseCath iVAC2L) during complex, high-risk angioplasty can help people with very weak hearts. It's for people who need a procedure for complicated coronary artery blockages.
This study looks at how well the Impella CP heart pump works for people who have a severe heart attack that causes their heart to pump too weakly to keep blood flowing to their body. It's a registry that follows your care to improve best practices.
This trial tests if starting and adjusting heart failure medications with the help of an Impella 5.5 heart pump can improve recovery for people in cardiogenic shock. It focuses on those who are not on enough guideline-directed medications.
