Study gives nod to drug-eluting stents in heart attack

Although drug-eluting stents have become widely used for the treatment of stable coronary artery disease, many cardiologists choose bare-metal stents for patients with heart attack, or myocardial infarction (MI), citing conflicting data about the safety and effectiveness of drug-eluting stents in this patient group.

Drug-eluting stents outperform bare-metal stents

New evidence from a large randomized study is answering important questions about the best approach to percutaneous coronary intervention (PCI) in patients with a type of heart attack known as ST-segment-elevation myocardial infarction (STEMI).

Special catheter that clears debris from artery helps blood flow in percutaneous coronary intervention

Use of a special catheter that sucks out, or aspirates, bits of plaque and blood clot that break loose during percutaneous coronary intervention (PCI) significantly enhances blood flow deep in the heart muscle in patients who are experiencing a heart attack, according to a recently published study.

Repeated episodes of stent thrombosis common

When a clot develops inside a coronary stent, it can block blood flow to the heart, potentially causing a heart attack or even death.

HDL-associated protein gene linked to heart disease risk

The gene for the HDL-associated protein paraoxonase 1 (PON1) appears to be associated with coronary artery disease and with the risk of developing adverse cardiac events, and variations in both the PON1 gene and its related enzyme activity may increase the risk for cardiovascular disease events, according to a study in the March 19 issue of JAMA , a theme issue on Genetics and Genomics.

New robotic interventional imaging technology holds promise of improved cancer care

New research released at the Society of Interventional Radiology's (SIR) Annual Scientific Meeting in Washington, D.C., this week, holds promise of a new interventional imaging capability using advanced robotics provided by Siemens Healthcare (www.siemens.com/healthcare), to improve the value of chemoembolization in treating cancer.

Study examines computed tomographic pulmonary angiography for diagnosing blood clots in the lung

New research indicates that a diagnostic strategy using computed tomographic pulmonary angiography (CTPA) may be a safe alternative to conventional lungs scans (known as ventilation-perfusion scans) for excluding the diagnosis of pulmonary embolism (blood clots in the lung vessels), although CTPA may detect more clots, according to a study in the current issue of JAMA: The Journal of the American Medical Association.

Study looks at prevalence of "false-positive" catheterization laboratory activation for patients with suspected STEMI

Physicians caring for patients suspected of having a heart attack may trigger "false-positive" activation of the cardiac catheterization laboratory based on test results suggestive of a heart attack, according to a study in the December 19 issue of JAMA: The Journal of the American Medical Association.

Computed tomography angiography accurate in detecting coronary artery disease

Computed tomography (CT) angiography is as accurate as an invasive angiogram in detecting coronary artery disease, according to the findings of the first two prospective multicenter 64-slice scanner trials presented today at the annual meeting of the Radiological Society of North America (RSNA).

Skipping meals to lose weight

Foregoing food for a day each month stood out among other religious practices in members of the Church of Jesus Christ of Latter-Day Saints (LDS or Mormons), who have lower rates of heart disease than other Americans, researchers reported at the American Heart Association's Scientific Sessions 2007.

64-slice CT scans a good test for clogged arteries

A study by an international team of cardiac imaging specialists, led by researchers at Johns Hopkins, concludes that sophisticated computed tomography (CT) scans of the heart and its surrounding arteries are almost as reliable and accurate as more invasive procedures to check for blockages.

Heart disease of the left main coronary artery is often an inherited condition that clusters in families

Moreover, they discovered that initially healthy siblings of a person with the condition were 2.5 times more likely to go on to develop some form of heart disease than were siblings of a patient with heart disease that did not relate to the left main coronary artery.

Coronary artery disease appears to increase prevalence of colorectal tumors

Patients in Hong Kong who were newly diagnosed with coronary artery disease had nearly twice the prevalence of colorectal tumors and cancers, with this association stronger in persons who had smoked or have the metabolic syndrome, according to a study in the Sept. 26 issue of JAMA: The Journal of the American Medical Association.
