Preventive PCI results in better outcomes than culprit artery PCI alone in ST elevation MI
Heart attack patients with ST elevation who undergo a preventive procedure to unblock additional coronary arteries have significantly better outcomes than those whose treatment is confined to the culprit blockage only, according to the results of the Preventive Angioplasty in Myocardial Infarction Trial.

Study finds mechanical chest compressions are equally as effective as manual CPR
Mechanical chest compressions with defibrillation during ongoing compressions are just as effective, but not superior to manual compressions, for delivering cardiopulmonary resuscitation (CPR) to patients in cardiac arrest, according to the results of the LUCAS in Cardiac Arrest study.

Case study reveals genetic discrimination in life insurance
A case study presented by health and legal experts from the University of Melbourne and University of Tasmania revealed an example of life insurance companies discriminating due to genetic test results for cancer pre-disposition.

Magnetic resonance imaging before ablation for atrial fibrosis helps predict success of treatment
In patients with atrial fibrillation, delayed enhancement magnetic resonance imaging (DE-MRI) performed before ablative treatment can stage the degree of damaged heart tissue (atrial fibrosis) and help predict whether treatment will be successful or not, according to results of Delayed Enhancement - MRI determinant of successful Catheter Ablation of Atrial Fibrillation trial.

Mycobacterium tuberculosis: Our African follower for over 70,000 years!
One of the deadliest infectious diseases of humankind emerged in Africa 70,000 years ago, a new genetic analysis of 259 Tuberculosis bacterial strains has shown.

Pre-treatment with prasugrel -- more risk, no benefit: ACCOAST
In patients with non-ST-elevation acute coronary syndrome, pre-treatment with the P2Y12 antagonist prasugrel prior to catheterization, significantly increases the risk of life-threatening bleeding without reducing the risk of major ischemic events, according to the results of the ACCOAST (A Comparison of Prasugrel at PCI or Time of Diagnosis of Non-ST Elevation Myocardial Infarction) trial.

Anticoagulant does not reduce rate of ischemic events among certain patients undergoing PCI
Use of the novel anticoagulant otamixaban did not reduce ischemic events compared with unfractionated heparin plus eptifibatide but increased bleeding among patients with non-ST-segment elevation acute coronary syndromes undergoing a percutaneous coronary intervention (PCI; procedures such as balloon angioplasty or stent placement used to open narrowed coronary arteries), according to a study published by JAMA.

Increased greenhouse gases and aerosols have similar effects on rainfall
Although greenhouse gases and aerosols have very distinct properties, their effects on spatial patterns of rainfall change are surprisingly similar, according to new research from the University of Hawaii at Manoa's International Pacific Research Center and Scripps Institution of Oceanography.

Stomach bacteria switch off human immune defenses to cause disease
Helicobacter pylori is a bacterium that establishes a life-long stomach infection in humans, which in some cases can lead to duodenal ulcers or stomach cancer.

New research shows that short episodes of brisk physical activity can have as positive an effect on weight as does the current recommendation of 10 or more minutes at a time.

Listening to favorite music improves endothelial function in CAD
Listening to favorite music improves endothelial function in patients with coronary artery disease, according to research presented at ESC Congress 2013 today by professor Marina Deljanin Ilic from Serbia.

Big belly increases death risk in heart attack survivors
Findings from the FAST-MI 2005 registry suggest that lifestyle interventions in heart attack patients should focus on losing abdominal fat.

Cracking bacteria's secrets may lead to new treatments
Scientists have found another chink in bacteria's armour, mapping for the first time the structure of a protein that plays an important role helping infection gain a foothold in the body.

A shorter interruption of anti-thrombotics does not influence peri-operative complications
A shortened pre-surgical interruption of anti-thrombotic therapy, compared to the more traditional one-week interruption, has no influence on perioperative complications in cardiac patients, according to the results of the PRAGUE 14 trial.
