ClinConnect Summary

The INTeGRATE trial is studying how well a heart pump called Impella 5.5® can help patients with a specific type of heart failure known as reduced ejection fraction heart failure (HFrEF), particularly when they are experiencing a serious condition called cardiogenic shock. This trial aims to find out if using the Impella pump can help start and improve the medical treatments that are recommended for heart failure while patients are in the hospital and after they go home.

To participate in this trial, you need to be between 18 and 75 years old and have a history of heart failure for less than five years. You also need to have a weakened heart function, indicated by a left ventricular ejection fraction (LVEF) of 40% or less. Additionally, you should be admitted to the hospital with worsening heart failure and meet specific criteria related to blood pressure or other heart issues. If you qualify, you can expect to receive the Impella pump during your hospital stay, and the study will monitor how well it helps you with your heart treatments. It's important to know that there are several health conditions that may prevent someone from being eligible for this study, so speaking with your doctor can help determine if this trial is right for you.
