Slower care for heart attack patients treated off hours and weekends

17.08.2005


Heart attack patients treated with primary percutaneous intervention (PCI) at hospitals after hours and on weekends wait longer to receive clot busters and other treatments and have a higher risk of death than those treated during regular hospital hours, researchers at Yale School of Medicine report in the August 17 issue of Journal of the American Medical Association (JAMA).



The researchers found that while 67.9 percent of heart attack patients were treated during off-hours (weekdays 5 p.m. to 7 p.m. and on weekends), the time from hospital arrival to receiving clot dissolving medications varied from only one minute longer wait for clot busting medications to 21 minutes longer wait for (PCI) therapy.

"The findings suggest that the delayed treatment associated with PCI treatment is associated with a greater mortality risk," said Harlan M. Krumholz, M.D., professor of medicine and public health at Yale School of Medicine. Krumholz is also director of the Robert Wood Johnson Clinical Scholars Program at Yale.


He added, "Many patients at night and on weekends have very long delays. This study highlights the need to focus on improving our systems of care during these times for patients who are referred for procedures to treat heart attacks."

Heart attack patients generally receive reperfusion therapy, which consists of either clot busting drugs to restore blood flow to an organ or tissue, or PCI treatments such as angioplasty where a catheter-guided balloon is used to open a narrowed coronary artery. Reperfusion therapy reduces the risk of death for eligible ST-segment elevation myocardial infarction (STEMI), which is detected on an electrocardiogram after a heart attack. The shorter the time from symptom onset to treatment, the greater the survival benefit with either therapy. Krumholz said all things being equal, PCI produces a better outcome, but delays will undermine that advantage.

The study also indicates that even during the day, many patients are not receiving rapid enough therapy. During the day, fewer than half of the patients undergoing PCI received treatment with the time frame recommended by the national guidelines.

Krumholz and collaborators point out that delays to PCI during off-hours are common to all types of hospitals, including high-volume PCE centers. The authors write that because delays to PCI can result in lower survival rates for STEMI patients, hospitals should commit to providing PCI care in a timely manner. Krumholz and his co-authors suggest hat this can be achieved by providing onsite, round-the-clock staffing of the cardiac catheterization laboratory. But the clinical benefits of providing this service must be weighed against the added cost.

Krumholz said other possible solutions include cross-training non-cardiac catheterization laboratory staff to assist with PCI during off-hours and transporting off-hour patients to institutions with continuous cardiac catheterization laboratory staffing.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
