    The technique, which involves a simple injection, could aid the recovery of hundreds of thousands of heart failure patients - and could even consign heart transplants to history. Researchers hope to increase levels of SERCA2a, a protein in heart muscle cells that plays an important role in heart muscle contraction The technique, which involves a simple injection, could aid the recovery of hundreds of thousands of heart failure patients. Heart transplants could even be consigned to history thanks to a trial by Imperial College, London, which aims to show for the first time that gene therapy could repair failing organs....

    Drugs that are used for treating Alzheimer's disease in its early stages are linked to a reduced risk of heart attacks and death, according to a large study of over 7,000 people with Alzheimer's disease in Sweden.The research, which is published online today (Wednesday) in the European Heart Journal [1], looked at cholinesterase inhibitors (ChEIs), such as donepezil, rivastigmine and galantamine, which are used for treating mild to moderate Alzheimer's disease [2]. Side-effects of ChEIs include a beneficial effect on the vagus nerve, which controls the rate at which the heart beats, and some experimental studies have suggested that ChEIs...

    Comment Now Follow Comments Earlier today I summarized the important new PREDIMED study published in the New England Journal of Medicine showing the cardiovascular benefits of the Mediterranean diet. This study– a rare and much welcome instance of a large randomized controlled study of a diet powered to reach conclusions about important cardiovascular endpoints– has been widely praised and will undoubtedly have a major effect in the field of nutrition and will influence lots of people to adopt some form of a Mediterranean diet. The study’s major potential weakness appears to be that the control group didn’t get a fair...
  • A Shotgun for Blood Clots

    Think of it as Liquid-Plumr for the circulatory system. Researchers have designed a clump of tiny particles that rides the current of the bloodstream, seeks out life-threatening blood clots, and obliterates them. The approach works in mice and could soon move on to human trials. Blood clots are bad news for the brain, heart, and other organs. These masses of blood cells can grow big enough to choke off veins and arteries, preventing oxygen from flowing to critical organs. One of the chief obstacles to dealing with blood clots is finding where they have lodged in the body. Even if...
  • Man Pulled Over for Being Radioactive (Connecticut)

    Man pulled over for being radioactive Last Wednesday, Mike Apatow was getting on to Interstate 84 in Newtown, CT, when police stopped him for no reason he could determine. When the cop told him that his car had set off his radioactivity detectors, it started making sense: Apatow was most certainly radioactive. Earlier in the day, Apatow had had a bit of radioactive material injected into his veins. He wasn't trying to turn himself into a superhero—just trying to keep himself alive. The off-duty firefighter had gone to a cardiology office to have a cardiac stress test, which tracks the...
  • Cardiologist Debunks Salt Myth

    01/06/2012 9:14:54 PM PST · by Pining_4_TX · 52 replies
    Has the tide turned for salt in 2012? Salt faces regular demonization from the media, lawmakers, and food police, with the hyperbolic Center for Science in the Public Interest (CSPI) even calling it the “deadly white powder you already snort.” But as cardiologist-turned-chef Michael S. Fenster points out in The Atlantic, studies have not conclusively shown that a reduction in dietary sodium equates with a reduction in hypertension or its resulting effects. Fenster also notes that while this theory “makes for great slogans, off the cuff advice, and lazy recommendations,” it “also makes for poor publicly mandated policy.” Big Apple...

Secor At the end of Dr. Seuss' How the Grinch Stole Christmas!, the titular villain undergoes a literal change of heart. His blood-pumping organ swells to three times its prior size. The ticker of the Burmese python (Python molurus) similarly balloons, but the cause isn't Christmas cheer—it's a big meal. A new study of recently fed snakes suggests that a precise mixture of fatty acids in the blood drives this cardiac growth, unveiling...

    Enlarge Image Self-healing? After a heart attack like this patient has suffered, cells in the heart might be able to make new muscle, a mouse study suggests. Credit: Fotosearch Heart attacks kill because they strangle heart muscle, destroying cells and preventing the organ from pumping properly. Now, researchers reveal that they have nudged cells within mouse hearts to repair some of the damage, a discovery that might prompt new treatments for heart attacks in humans. Researchers are probing several ways to encourage the heart to fix itself. Last year, for instance, cardiac stem cell biologist Deepak Srivastava of the...

    FARMINGTON— Cardiologists at the University of Connecticut Health Center have identified a protein fragment that when detected in the blood can be a predictor of a heart attack. Their research, led by Dr. Bruce Liang, director of the Pat and Jim Calhoun Cardiology Center, is published in the Jan. 11 issue of the Journal of the American College of Cardiology. Cardiologists found that heart attack patients had elevated levels of the protein fragment known as Caspase-3 p17 in their blood. “We’ve discovered a new biomarker for heart attack, and showed that apoptosis, or a particular kind of cell death, is...
  • Study finds fat hormone's long-sought link to heart protection

    A protein called T-cadherin docks the fat hormone adiponectin to the heart, where it guards against stress-induced damageLA JOLLA, Calif., November 1, 2010 – One of the many advantages of maintaining a normal body weight is having healthy fat, which in turn supports a healthy heart. Fat tissue is increasingly seen as more than just a storage depot – it's also an active secretory organ that normally produces high levels of a cardioprotective hormone called adiponectin. How adiponectin protects the hearts of healthy people has long been a mystery, and now a team led by Barbara Ranscht, Ph.D. and Pilar...

    Harry Kalas, the Phillies' Hall of Fame announcer, died at 1:20 p.m. today, the Phillies announced. Mr. Kalas collapsed in the press box at Nationals Stadium in Washington at about 12:30 p.m. and was rushed to George Washington University Medial Center. The cause of the death was not announced. Today's game against the Nationals will be played, but the team will not visit the White House tomorrow. Kalas, who was found unconsious, missed most of spring training after undergoing undisclosed surgery in Feburary. That surgery was unrelated to the detached retina that sidelined him for part of last season. Kalas,...

    It's humbling to see medical dogma overturned, but that is exactly what happened when, contrary to deeply embedded thought, scientists led by Jonas Frisen from the Karolinska Institute in Stockholm reported in Science today that the heart can grow new muscle cells, and does so regularly, albeit slowly, in the course of a lifetime. To cardiologists, this is a blockbuster discovery, since the heart has been pegged as a disadvantaged organ in terms of injury, healing, and repair. Susceptible to coronary blockages that can cut off blood and destroy major hunks of heart muscle at one time in a heart...

The amount of carbon-14 in the atmosphere has gradually diminished since 1963, when above-ground tests were banned, as it gets incorporated into plants and animals or diffuses into the oceans. In the body, carbon-14 in the diet gets into the DNA of new cells and stays unchanged...

    It's been a dream for a decade: a single daily pill combining aspirin, cholesterol medicine and blood pressure drugs — everything people need to prevent heart attacks and strokes in a cheap, generic form. Skeptics said five medicines rolled into a single pill would mean five times more side effects. Some people would get drugs they don't need, while others would get too little. One-size-fits-all would turn out to fit very few, they warned. Now the first big test of the "polypill" has proved them wrong. The experimental combo pill was as effective as nearly all of its components taken...

    Cardiologists have opened another front in the rancorous debate over expensive medical technologies, questioning the conclusions of a new study finding that high-resolution computer scans of the heart are almost as effective as conventional angiograms. The debate reveals a deep rift among heart specialists over the use of 64-slice or CT angiography, which produces mesmerizing 3-D images of the heart and blood vessels. CT scans are faster and less invasive than conventional angiograms, the gold standard for diagnosis and identification of blockages, but they expose patients to higher doses of radiation, which may increase the risk of cancer. Angiograms, on...

    July 22, 2008 — A new fissure is creeping through the cardiology community, dividing those in favor of risk-factor screening and prevention on one side from those who advocate early screening for the disease itself. The debate is playing out online July 29, 2008 in the Journal of the American College of Cardiology, with Drs Jay Cohn and Daniel Duprez (University of Minnesota Medical School, Minneapolis) arguing in favor of early identification of disease through simple screening tests, and Drs Philip Greenland and Donald Lloyd-Jones (Northwestern University, Chicago, IL) urging clinicians to focus on risk factors and steer clear of...

    Apart from its sadness, Tim Russert’s death this month at 58 was deeply unsettling to many people who, like him, had been earnestly following their doctors’ advice on drugs, diet and exercise in hopes of avoiding a heart attack. Mr. Russert, the moderator of “Meet the Press” on NBC News, took blood pressure and cholesterol pills and aspirin, rode an exercise bike, had yearly stress tests and other exams and was dutifully trying to lose weight. But he died of a heart attack anyway. An article in The New York Times last week about his medical care led to e-mail...

    Given the great strides that have been made in preventing and treating heart disease, what explains Tim Russert’s sudden death last week at 58 from a heart attack? The answer, at least in part, is that although doctors knew that Mr. Russert, the longtime moderator of “Meet the Press” on NBC, had coronary artery disease and were treating him for it, they did not realize how severe the disease was because he did not have chest pain or other telltale symptoms that would have justified the kind of invasive tests needed to make a definitive diagnosis. In that sense, his...

    The tiny stent sparked a lucrative industry--and made Dr. Samin Sharma a star. Then questions arose about the device's safety and efficacy. On a sweltering summer morning, Dr. Samin K. Sharma marches into the cardiology wing of Mount Sinai Hospital in New York, prepared for a 16-hour day in which he will clear and repair the arteries of 18 patients. Sharma specializes in installing stents, tiny metal devices that hold open blocked blood vessels. As he'll be the first to note, he does more stent procedures than anyone else in doctor-rich New York and possibly in the entire country. An...
