Heart Attack Patients Benefit as Interventional Cardiologists Increasingly Perform PCI Through Radial Artery Access in Wrist

Las Vegas, Nev.  — Even when treating critically ill heart attack patients, interventional cardiologists are increasingly adopting a safer—though more technically challenging—procedure for threading balloon-tipped catheters and stents into the heart. According to a study reported this week at the SCAI 2014 Scientific Sessions, use of the radial artery in the wrist as the access point for percutaneous coronary intervention (PCI) is growing steadily in heart attack patients and results in significantly fewer bleeding complications and no increase in mortality.

Radial-artery access is an alternative to use of the femoral artery in the groin, the traditional approach. It has been found to reduce bleeding complications, andbe more comfortable for patients and reduce costs; however, it may be more time-consuming and requires additional physician training.

The new study, led by Michael Howe, M.D., of the University of Michigan Cardiovascular Center in Ann Arbor, Mich., analyzed how often radial or femoral access was used during PCI for heart attack in 14,780 patients treated at 44 hospitals in Michigan from January 2010 through June 2013. In early 2010, less than 1 percent of patients treated with PCI had radial artery access, but by mid-2013 that rate had grown to 14.2 percent. Heart attack patients treated with radial artery access had half the rate of bleeding complications when compared to patients treated with femoral artery access (2.42% vs. 5.62%) and less than two-thirds the likelihood of needing a blood transfusion (3.42% vs. 5.3%). There was no significant difference in in-hospital mortality (1.51% vs. 2.34%). Dr. Howe noted that adoption of radial artery access was growing about twice as fast in patients undergoing non-emergency PCI.

In 2013, SCAI published a consensus statement on best practices in transradial procedures.

Dr. Howe reports no potential conflicts of interest.

Dr. Howe will present the study “The Underutilization of Radial Access During PCI for STEMI; Insights from the Blue Cross Blue Shield of Michigan Cardiovascular Consortium (BMC2)” in a poster session on Wednesday, May 28, 2014, 1:00 p.m. to 4:00 p.m. (Pacific Time).
