New meat-eating dinosaur duo from Sahara ate like hyenas, sharks
Two new 110 million-year-old dinosaurs unearthed in the Sahara Desert highlight the unusual meat-eaters that prowled southern continents during the Cretaceous Period. Named Kryptops and Eocarcharia in a paper appearing this month in the scientific journal Acta Palaeontologica Polonica, the fossils were discovered in 2000 on an expedition led by... view more...

Younger women appear to be at increased risk for depression after heart attack
Women age 60 years or younger are more likely than other patients to be depressed during hospitalization for heart attack. view more (2006-04-25)
Many patients with heart disease have poor knowledge of heart attack symptoms
Nearly half of patients with a history of heart disease have poor knowledge about the symptoms of a heart attack and do not perceive themselves to have an elevated cardiovascular risk, according to a report in the May 26 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. view more (2008-05-27)
A possible risk group for statin use
In a patient study of over 1,000 individuals with coronary artery disease (CAD), researchers have found that high levels of an enzyme called PLTP significantly increased the risk of heart attack in the subset of patients taking statins. While follow-up studies will be needed to tease out the exact connection between PLTP and statins, this... view more... (2009-03-24)
Study shows emergency physicians have good first instincts in diagnosing heart attacks
A study out of Wake Forest University Baptist Medical Center demonstrates emergency room doctors are correctly identifying patients who are having a heart attack, even when laboratory tests haven't yet confirmed it. view more (2008-07-24)
Depression after heart attack increases subsequent risk
This was the finding of a study published today, Tuesday 14 September, in the British Journal of Health Psychology by Dr Everard Thornton, of the University of Liverpool, and Claire Hallas, of the University of Staffordshire. view more (1999-09-07)
UF scientists discover evolutionary origin of fins, limbs
Evolutionarily speaking, the genetic instructions used to construct and position our limbs were being perfected more than half a billion years ago in fishes, not along the sides of the body where the fins that preceded human arms and legs sprouted, but at the midline that runs along the backbone and belly. view more (2006-07-27)
Obesity and diabetes double risk of HF -- patients with both conditions 'very difficult' to treat
The twin epidemics of obesity and type 2 diabetes will continue to fuel an explosion in heart failure, already the world's most prevalent chronic cardiovascular disease. view more (2009-06-01)
Number of cardiovascular risk factors could determine safety of intravenous gammaglobulin treatment
New research out of Wake Forest University School of Medicine identifies the presence of cardiovascular risk factors as an indicator of how likely it is that elderly, hospitalized patients who receive intravenous immunoglobulin (IVIg) treatment will have a stroke or heart attack. view more (2009-03-05)
Emergency angioplasty use rises, but some patients still miss out
Compared with their counterparts a decade ago, today's 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 treatment still do not receive it. view more (2007-08-03)
Mathematical model identifies genes which battle hepatitis C
Joint research by Dr. Leonid Brodsky, of the Institute of Evolution of the University of Haifa, and Dr. Milton Taylor, of Indiana University, led to the discovery of a mathematical method which can identify which genes in our bodies conduct the battle against the various viruses that attack us. view more (2007-07-20)
APOLIPOPROTEINS COULD BE BETTER PREDICTOR OF HEART ATTACK THAN CHOLESTEROL (pp 2012, 2026)
Measurement of lipid components called apolipoproteins could be a better indicator of heart-attack risk than conventional cholesterol assessment, conclude authors of a study in this week's issue of THE LANCET. Hypercholesterolaemia, especially high concentrations of LDL-cholesterol, is one of the strongest risk factors for atherosclerotic... view more... (2001-12-12)
Risk of sudden cardiac death appears increased within 30 days of heart attack
The risk of sudden cardiac death following a heart attack has declined significantly in the past 30 years, although patients appear to be at elevated risk for sudden cardiac death for the first month after having a heart attack, after which time their risk decreases unless they develop heart failure, according to a study in the November 5 issue of... view more...

Weekends peak time for heart attacks for young and middle aged men
Weekends are the peak time for heart attacks in young and middle aged men in France, suggests a study in Heart. Mondays have often been cited as the critical day for heart attacks, with the impending stress of the working week sometimes suggested as a precipitating factor. The researchers looked at data on heart attack patterns and death rates... view more... (2001-08-20)
Women fast catching up with men on risks of sudden death after heart attack
Women are fast catching up with men when it comes to risk of sudden death after a heart attack, reveals research in Heart. view more (2002-11-18)
New Combination Therapy Could Reduce Ischaemia After Heart Attack (p 605)
Encouraging results from a fast-track study published in this week's issue of THE LANCET suggest a new therapeutic strategy for reducing ischaemic complications (coronary artery blockage) after heart attack. The treatment of acute heart attack requires combination of several therapies. Fibrinolytic agents given together with aspirin and... view more... (2001-08-22)
Lighting up the heart
A major breakthrough in research could lead to improved recovery of the heart when it is re-started after a heart attack or cardiac surgery. view more (2006-09-22)
Arrythmia associated with heart attacks linked to higher risk of death
Heart attack patients who develop serious arrhythmia in connection with procedures to open blocked arteries face a significantly higher risk of death for several months after the procedure, when compared to similar patients who do not develop such complications, according to new research from Duke University Medical Center. view more (2009-05-06)
ANGIOPLASTY OR MEDICAL THERAPY IMMEDIATELY AFTER HEART ATTACK? (p 814, 825 )
Authors of a study in this week’s issue of THE LANCET suggest that there is no difference in treatment outcome of pre-hospital medical therapy with anti-clotting drugs or emergency angioplasty after severe heart attack. Although the use of anti-clotting drugs before hospital admission (prehospital fibrinolysis) and primary angioplasty... view more... (2002-09-11)
Stem cell therapy successfully treats heart attack in animals
Final results of a study conducted at Johns Hopkins show that stem cell therapy can be used effectively to treat heart attacks, or myocardial infarction, in pigs. view more (2005-07-26)
