Response time to open arteries for most critical patients still too slow
Date:11/16/2011

most of the damage has been done so UTHealth researchers have been concentrating on how to shorten that time to two hours or less.

The only way to lower the current time from symptoms to opening the artery is to treat the patient in the ambulance, McCarthy said. A year ago he presented results of a UTHealth clinical trial called Pre-Hospital Administration of Thrombolytic Therapy with Urgent Culprit Artery Revascularization (PATCAR). That trial showed that the mortality rate of patients arriving via EMS could be lowered to 2.9 percent by giving them a low dose of a clot-busting drug intravenously before they arrived at the hospital. The research was a collaboration of UTHealth, Memorial Hermann Heart & Vascular Institute-Texas Medical Center (HVI) and the Houston Fire Department.

"We know we've optimized the hospital system and integrated that with EMS but for the cohort that calls 911, that's still not enough," he said. "We need to figure out something else." The researchers are seeking additional funding to expand PATCAR to more patients.

The researchers looked at 37,715 patients in the American College of Cardiology's National Cardiovascular Data Registry. The presentation title is "EMS Transport of STEMI Patients Shortens Ischemic Times and is Associated with a Higher Risk Population: Results from the ACTION Registry."
