1-year follow-up data shows bivalirudin reduces clinical events in heart attack patients undergoing angioplasty (HORIZONS-AMI study)
Use of the anti-clotting drug bivalirudin results in less complications/clinical events in heart attack patients undergoing angioplasty than does use of the conventional treatment of heparin plus a glycoprotein inhibitor.

High caffeine intake can lead to arrhythmias
Coffee is routinely consumed in countries within the Mediterranean basin.

Heart failure patients may benefit from treatment of anemia with erythropoietin
Heart failure patients may benefit from treatment of anemia similarly to those with chronic kidney disease or cancer.

Otamixaban is promising new treatment for patients with acute coronary syndromes
An article published online first and in an upcoming edition of the Lancet shows that otamixaban is a promising new agent for patients with acute coronary syndromes (heart attacks or sudden worsening of angina).

No evidence for the routine use of aspirin in people with asymptomatic vascular events
The routine use of aspirin for the primary prevention of vascular events in people with asymptomatic disease cannot be supported, according to results from the Aspirin for Asymptomatic Atherosclerosis study.

Failing heart, failing kidney: Double trouble?
Concomitant kidney dysfunction and/or worsening renal function in patients with heart failure is a frequent finding and is associated with a poor prognosis.

World's smallest semiconductor laser heralds new era in optical science
UC Berkeley researchers have reached a new milestone in laser physics by creating the world's smallest semiconductor laser, capable of generating visible light in a space smaller than a single protein molecule.

Researchers identify protein involved in causing gum disease, osteoporosis, arthritis
Investigators at Hospital for Special Surgery, collaborating with researchers from other institutions, have contributed to the discovery that a gene called interferon regulator factor-8 is involved in the development of diseases such as periodontitis, rheumatoid arthritis and osteoporosis.

100 million women in the prime of their lives have endometriosis
The World Endometriosis Research Foundation and the European Society of Human Reproduction and Embryology are proud to announce the first ever prospective study to assess the hidden cost of endometriosis to society and to women with the disease.

Counting duplicated genome segments now possible
A new computational method has proven its usefulness in counting duplicated sequences in human genomes and in initially assessing their content.

Double doses of clopidogrel better than standard doses for heart patients undergoing angioplasty
A landmark international study led by McMaster University researchers found high doses of the blood thinner clopidogrel significantly reduce complications in heart patients undergoing angioplasty to clear blocked arteries.

CABG vs. PCI: Call for multidisciplinary approach to decide in complex CAD cases
Important new evidence about revascularization in patients with severe coronary artery disease can be found in the recently published interim analyses of the SYNTAX Trial of 1,800 patients with left main and/or three vessel coronary artery disease randomized to PCI or CABG.

Otamixaban for the treatment of patients with non-ST-elevation acute coronary syndromes
Data from a Phase II trial of an investigational intravenous drug designed to block the formation of blood clots shows potential to reduce the risk of death, a second heart attack, or other coronary complications compared with the current standard of care in patients presenting with acute coronary syndromes.

Termites eavesdrop on competitors to survive
The drywood termite, Cryptotermes secundus, eavesdrops on its more aggressive subterranean competitor, Coptotermes acinaciformis, to avoid contact with it, according to scientists from CSIRO Entomology and the University of New South Wales at the Australian Defence Force Academy.

Opals set to shine with new grading technology
CSIRO and a consortium of Australian Opal miners have unveiled the world's first automated device to grade opals using image analysis, at the 2009 National Council of Jewelery Valuers forum in Sydney.

Diabetic patients require global care
Diabetes mellitus-associated coronary artery disease is assuming epidemic proportions, especially in western countries.

New oral antiplatelet agent ticagrelor first to show reduction in cardiovascular death
The presentation of the PLATO study showed that ticagrelor reduced the rate of cardiovascular events from 11.7 percent to 9.8 percent compared clopidogrel, without an increase in major bleeding.

Do women who smoke like men die like men?
Smoking still kills more men than women, because men started smoking substantial numbers of cigarettes long before women did.

Caltech neuroscientists find brain region responsible for our sense of personal space
In a finding that sheds new light on the neural mechanisms involved in social behavior, neuroscientists at the California Institute of Technology have pinpointed the brain structure responsible for our sense of personal space.

Get the world on its feet: The role of exercise training
Western societies are struggling to pay for their ever increasing medical budgets.

MSU researchers improve zebrafish cloning methods
A team of Michigan State University researchers has developed a new, more efficient way of cloning zebra fish, a breakthrough that could have implications for human health research.

Think zinc: Molecular sensor could reveal zinc's role in diseases
Scientists have developed a new molecular sensor that can reveal the amount of zinc in cells, which could tell us more about a number of diseases, including type 2 diabetes.

Dabigatran vs. warfarin as long-term anticoagulant therapy in atrial fibrillation
The anticoagulant dabigatran is more effective than warfarin in the prevention of stroke in patients with atrial fibrillation, according to results from the RE-LY study (Randomized Evaluation of Long-term anticoagulant therapY).

No increased risk with drug eluting stents -- but late stent thrombosis remains a concern
A five-year follow-up of all patients treated with drug-eluting compared to bare-metal stents in Sweden shows similar rates of death or myocardial infarction and an important improvement in the rate of restenosis in high-risk patients.

Heart failure: More or less malignant than cancer?
A study of 1.1 million Swedish patients reveals that the population impact of heart failure is as great as the most common forms of cancer.
