Emergency angioplasty use rises

Compared with their counterparts a decade ago, todays heart attack patients are receiving emergency angioplasty or clot-busting drugs to re-open clogged arteries at a far greater rate, but 10 percent of patients who could benefit from this life-saving therapy still do not receive it, as per a research studypublished in The American Journal of Medicine by Yale and University of Michigan researchers.

The results also showed that the chance of missing out on lifesaving emergency therapy was highest among patients without typical symptoms like chest pain, patients who did not arrive at the hospital until six or more hours after the heart attack began, female patients, those over age 75 and non-whites.

The 10-year study was based on data from 238,291 heart attack patients between 1994 and 2003 who were listed in the National Registry of Myocardial Infarction. The patients had a particular kind of heart attack called ST-elevated myocardial infarction (STEMI). It is the most current and comprehensive look at the use of emergency reperfusion, a therapy that can restore blood flow to the heart muscle. To track the changes in emergency reperfusion treatment over time, the scientists divided the study data into three time periods: June 1994 through May 1997, June 1997 through May 2000, and June 2000 through May 2003.

This study has good and bad news, said senior author Harlan M. Krumholz, M.D., the Harold H. Hines, Jr. Professor of Medicine at Yale School of Medicine. We have definitely made progress in treating appropriate patients, but our findings indicate that we need to improve further to be sure that no patient who could benefit from therapy is missed.

We may never be able to get to 100 percent, but 10 percent of eligible patients going untreated is still too a number of, said first author Brahmajee Nallamothu, M.D., assistant professor of cardiovascular medicine at the University of Michigan Medical School. We hope our study highlights the opportunities to improve care and especially some of the at risk subgroups still less likely to receive reperfusion treatment despite eligibility, so that we can focus our clinical efforts on them.

Hospitals around the nation, including Yale-New Haven and University of Michigan, are taking part in a national campaign to reduce door-to-balloon timesthe time from when a STEMI patient enters hospital doors to the time blood flow is restored to the heart by opening a blockage with angioplasty.
