St. David’s North Austin Medical Center participates in national study on cardiogenic shock

AUSTIN, Texas—St. David’s North Austin Medical Center is among three hospitals in Texas to participate in the National Cardiogenic Shock Initiative (NCSI), a multicenter registry study aimed at increasing survival for cardiogenic shock patients.

While cardiogenic shock is rare, it is becoming more common among Americans. According to the NCSI, the amount of cardiogenic shock cases in the U.S. increased by more than 15,000 between 2009 and 2016. This condition is often caused by a severe heart attack, which stops the heart from pumping enough blood to the body’s vital organs.

“St. David’s North Austin Medical Center has mirrored and will continue to mirror best practices developed in the National Cardiogenic Shock Initiative,” Dr. Robert Wozniak, cardiology medical director at St. David’s North Austin Medical Center, said. “The pilot study of new treatment protocols increased survival rates from 50 percent to 76 percent. This was, and continues to be, the biggest break-through in cardiogenic shock treatment in over 20 years.”

Healthcare systems that have agreed to adopt the NCSI treatment protocol using the Impella heart pump were invited to join the registry to assist in analyzing patient outcomes.

The NCSI treatment protocol for cardiogenic shock requires the insertion of the Impella heart pump as a first step to continue blood flow and enable the heart to rest and potentially recover. After the pump is placed through a catheter, cardiologists insert a stent to unblock narrowed coronary arteries.

Select patients treated at participating NCSI facilities using this protocol will be asked to participate in the NCSI registry.
