Medication does not reduce risk of recurrent cardiac events among patients with diabetes
Use of the drug aleglitazar, which has shown the ability to lower glucose levels and have favorable effects on cholesterol, did not reduce the risk of cardiovascular death, heart attack or stroke among patients with type 2 diabetes and recent heart attack or unstable angina, according to a study.

Too many diet drinks may spell heart trouble for older women
It appears healthy postmenopausal women who drink two or more diet drinks a day may be more likely to have a heart attack, stroke or other cardiovascular problems, according to research. In fact, compared to women who never or only rarely consume diet drinks, those who consumed two or more a day were 30 percent more likely to suffer a cardiovascular event and 50 percent more likely to die from related disease.

Do No Harm: Stories of Life, Death and Brain Surgery review
Patients see neurosurgeons as gods, but what is the reality? Henry Marsh has written a memoir of startling candourWe go to doctors for help and healing; we don't expect them to make us worse. Most people know the aphorism taught to medical students, attributed to the ancient Greek Hippocrates but timeless in its quiet sanity: "First, do no harm." But many medical treatments do cause harm: learning how to navigate the risks of drug therapies, as well as the catastrophic consequences of botched or inadvised surgical operations, is a big part of why training doctors takes so long. Even the simplest of therapies carries the ri...

Hip, knee replacements may boost cardiovascular health in osteoarthritis patients
Total joint replacement may reduce the risk for 'cardiac events,' including heart attack and stroke, and boost long-term survival, new research shows. Physical inactivity is a major risk factor for cardiovascular disease. Osteoarthritis ─ a progressive disease of the joints affecting a third of persons over the age of 65 ─ causes pain and limits mobility. The researchers concluded that the results are probably due to the increased capability for moderate physical activity (such as a brisk walk several times a week), which has "direct benefits for hypertension, obesity and diabetes, all of which are risk factors for car...

Early atherosclerotic plaques in vessel wall regress completely when cholesterol levels are lowered
Early but not advanced forms of atherosclerotic plaques in the vessel wall disappear when the levels of 'bad' cholesterol are lowered, according to a study in mice. The findings indicate that preventative cholesterol-lowering treatment could prevent more advanced, clinically relevant plaque to develop. Almost half of all deaths worldwide are caused by strokes and heart attacks. The main underlying cause is atherosclerosis, where fat accumulates in the blood vessel walls in the so-called plaques. Atherosclerosis is a progressive disease where advanced and unstable plaques develop over time. When these plaques burst a blood ...

Seasonal flu vaccine may cut stroke risk
Having the seasonal flu jab could reduce the risk of suffering a stroke by almost a quarter, researchers have found. Academics discovered that patients who had been vaccinated against influenza were 24% less likely to suffer a stroke in the same flu season. In 2010, the same research team showed a similar link between flu vaccination and reduced risk of heart attack. "Further experimental studies would be needed to better understand the relationship between flu vaccination and stroke risk. However, these findings reinforce the value of the U.K.'s national flu vaccination program with reduced risk of stroke appearing to be ...

Nanoparticle pinpoints blood vessel plaques
A team of researchers has developed a multifunctional nanoparticle that enables magnetic resonance imaging to pinpoint blood vessel plaques caused by atherosclerosis. The technology is a step toward creating a non-invasive method of identifying plaques vulnerable to rupture -- the cause of heart attack and stroke -- in time for treatment.

A safe, effective diet pill - the elusive holy grail
Trade in illegal, ineffective drugs flourishes as pharmaceutical industry repeatedly fails to produce successful pillAttempts to invent a safe and effective diet pill have foundered time and again, allowing the internet trade in illegal and ineffective herbal supplements and dangerous drugs, such as DNP, to flourish.A successful diet pill could make billions for the pharmaceutical industry, but efforts to date have ended in disaster, with patients harmed, drugs banned and massive compensation paid out.Fen-phen, an appetite suppressant, was the most spectacular failure. It was withdrawn in the US in 1997 after causing wides...

Cardiologists cast doubt on new statin recommendations
Guidelines released last week don't accurately estimate who's at enough risk of heart attack or stroke to merit the drug therapy, critics say.Some of the nation's most influential cardiologists are challenging new recommendations that would greatly expand the number of Americans taking a statin medication to reduce their chances of a heart attack or stroke.

Girl dies after being attacked by family dog
Animal, believed to be a pet, attacked girl at home in Mountsorrel, Leicestershire. She died in hospitalA four-year-old girl has died after being attacked by a dog in Leicestershire.The girl, named locally as Lexi Hudson, died in hospital.A Leicestershire police spokeswoman said: "We were called to a flat in Mountsorrel at about 12.15pm following a report of a young girl being attacked by a dog, believed to be the family pet. The girl was taken to the Queen's medical centre in Nottingham where she has since died."Lexi is believed to have lived with her mother Jodi Hudson in the flat and was described by neighbours as a fri...

Should I take statins?
Since 80% of cardiovascular disease is caused by lack of exercise, poor diet and smoking, it would be better to address these factors rather than pop a statinShould everyone over 50 be taking statins? asked an editorial in the Lancet last year. No, said an analysis article in last week's BMJ. Statins, in case you've escaped the hype, are drugs that block an enzyme in the liver that's needed to make cholesterol (we make it as well as eat it). Statins reduce levels of low density lipoproteins – the bad cholesterol that furs up arteries and can cause heart disease. But is there any benefit in taking a statin if yo...

Heart attack death rates halve from 2001-12 but cancer mortalities rise
But ONS mortality data for period show circulatory disease as overall top cause of deaths in England and WalesDeaths from heart attacks and stroke halved in England and Wales over the first 11 years of this century, while the numbers dying from cancer rose, according to newly published mortality data from the Office for National Statistics.The 21st century mortality files from the ONS contain a vast amount of data not only about the big killers of modern times but also the more surprising and less likely accidental causes of mortality.Only three people died from snake bites, all men, between 2001 and 2012. One man died of ...

Heparin, grad students, a clinical revolution and giving credit where it's due
The story of a grad student who overcame remarkable odds only to be denied his moment of glory, or a tale of dark deceit and devilish doings? The story of heparin is as complicated as the chemistry itselfBlood is remarkable.A liquid that carries nutrients, waste products and the ever-vigilant cells of the immune system around the body, blood rapidly turns into a solid when it leaves its veins and arteries and becomes exposed to bodily tissues or the air outside. This process of solidification – clotting, or coagulation – is executed and controlled by a complex set of reactions and interactions primarily involving the e...

Stem cells: what happened to the radical breakthroughs?
Much was promised in the late 1990s, but the challenge of advances such as growing whole human organs has been difficult to deliverIt's 1998 and science is taking big strides. The first cloned mammal, Dolly the Sheep, has just had her first lamb; the first robotically assisted heart surgery has been completed; Furbys have hit the shelves. In a bold announcement, biomedical engineer Professor Michael Sefton declared that within 10 years, scientists would have grown an entire heart, fit for transplant. "We're shooting big," he said. "Our vision is that we'll be able to pop out a damaged heart and replace it as easily as you ...
