NEW ORLEANS — Patients who presented to the hospital after experiencing an out-of-hospital cardiac arrest and who then underwent coronary angiography had an increased survival rate regardless of whether percutaneous coronary intervention was performed, according to study results presented at the American Heart Association Scientific Sessions.

Tyler F. Vadeboncoeur, MD, from the Mayo Clinic in Jacksonville, Florida, and colleagues conducted a prospective observational study of 1,881 adult patients who were admitted to one of Arizona’s 40 recognized cardiac receiving centers from January 2010 to December 2014 after experiencing an out-of-hospital cardiac arrest to assess the association between coronary angiography alone and coronary angiography plus PCI after out-of-hospital cardiac arrest in patients who did not experience STEMI.

Fifty-four percent of the 1,881 patients who survived to hospitalization underwent coronary angiography, and 48% of those patients underwent PCI after coronary angiography. Twenty percent of the patient population underwent STEMI. Ninety percent of those patients received coronary angiography and 70% of those patients underwent PCI. Of the 1,230 patients who did not present to the hospital with STEMI, 43% received coronary angiography and 30% of those patients underwent PCI.

In the non-STEMI patient population, coronary angiography was associated with an increased survival benefit regardless if a patient did (adjusted OR = 2.03; 95% CI, 1.33-3.12) or did not (a OR = 2.62; 95% CI, 1.92-3.56) undergo PCI.

Vadeboncoeur acknowledged that the results suggest selection bias, particularly in the group that received coronary angiography but did not undergo PCI.

“But maybe there are other benefits of going to coronary angiography earlier,” he said during the presentation. “Getting cardiology involved earlier, getting a central line, getting a balloon pump –  more intensive care,” could be a possible benefit other than revascularization, he said.  – by Ryan McDonald
