Universal bone marrow cell spurs growth of vessels and heart muscle
10 Nov 03 | A "universal stem cell clone" found in adult bone marrow regenerated blood vessels and heart muscle. The cells, called human bone marrow-derived multipotent stem cells (hBMSC), were implanted into animal hearts where they formed multiple cell types.
Bone marrow cells improve failing heart function
10 Nov 03 | Bone marrow stem cell therapy holds promise as a novel therapy for heart failure, offering a sustained improvement up to six months. Researchers tested mononuclear bone marrow cell transplant injections in patients with severe ischemic heart failure.
More risk factors for heart disease increase Medicare cost
09 Nov 03 | Preventing heart disease risk factors in younger adults could be a money-saving investment for the federal Medicare program, researchers reported in two studies presented at the American Heart Association's Scientific Sessions 2003.
Heart failure care inconsistent
09 Nov 03 | A third of heart failure patients left hospitals without some of the tried-and-true therapies that could add years to their lives, according to one of the largest studies of its kind, reported at the American Heart Association's Scientific Sessions.
For smokers, air pollution is a drag on the heart
09 Nov 03 | Short-term rises in air pollution might trigger heart attacks – especially among smokers – according to a study presented today. The researchers found that on days with high air pollution, current smokers had a greater risk of heart attack.
Elementary signs of heart disease found in children
09 Nov 03 | About one in eight schoolchildren have three or more risk factors of the metabolic syndrome, a precursor of cardiovascular disease, researchers reported today. The risk was about 1.6 times higher for girls than boys.
Quality improvement program enhances heart care, closes gender gap
09 Nov 03 | Using a low-cost, hospital quality improvement program substantially improved care for heart attack patients and significantly reduced treatment differences for men and women in one year, researchers reported today.
Public access defibrillator use increasing
09 Nov 03 | Use of portable defibrillators by non-emergency responders on victims of cardiac arrest doubled during a four-year period in Seattle and King County, Washington. Survival rates were similar to or better than those of people treated by professionals.
Vital sign device improves resuscitation monitoring
08 Nov 03 | A small device, called "Vital Dust," can give doctors the "big picture" of patients' vital signs, researchers reported today during the Resuscitation Science Symposium at the American Heart Association's Scientific Sessions 2003.
Unusual fatigue may be warning symptom of heart attack in women
04 Nov 03 | In a study of women who had heart attacks, symptoms such as unexplained fatigue or trouble sleeping were experienced as much as a month before the heart attack, indicating the possibility that acting on these advance symptoms could prevent an attack.
ApoB: a better marker for heart disease risk than "bad" cholesterol
28 Oct 03 | A cholesterol component called apolipoprotein B may be more strongly linked to several heart disease risk factors than the LDL cholesterol for which millions of Americans are screened each year, researchers reported today.
New statement says people with kidney disease are at highest risk for heart disease
28 Oct 03 | People with chronic kidney disease (CKD), even those in the early stages of the disorder, are in the highest-risk group for cardiovascular disease, the American Heart Association said in a statement in today's Circulation: Journal of the AHA.
New cookbook touts heart-healthy recipes over fad diets
28 Oct 03 | With U.S. obesity rates on the rise, the abundance of best-selling books on the topic is focused more on taking off the pounds than on being healthy, and consumers can feel bombarded and confused by so many different 'get-thin-now' theories.
Artery wall stem cells can form tissues, including bone
28 Oct 03 | Artery walls contain a type of stem cell that can form bone, smooth muscle, cartilage, or marrow – a discovery that may lead to new forms of cellular transplant and treatments, researchers report in today's rapid access issue of Circulation.
New York City restaurant survey supports smoking ban
22 Oct 03 | The impartial Zagat survey of the impact of New York City's smoking ban confirms what every other credible survey has shown: Smoking bans are popular with the public and pose no economic threat to restaurants, bars or other businesses.
Interleukin-6 may be best marker for heart disease, stroke in elderly
21 Oct 03 | The inflammatory marker interleukin-6 (IL-6) is a stronger predictor of heart attack or stroke in elderly people than C-reactive protein, according to research in today's rapid access issue of Circulation: Journal of the American Heart Association.
New recommendations issued on treating device infections
21 Oct 03 | Coronary artery stents, pacemakers, defibrillators and other devices have greatly enhanced heart disease treatment and extended patients' lives.
While the chance of a device infection is rare, it is important that infections be treated promptly.
Cell infusions boost heart function, revive damaged heart muscle
14 Oct 03 | Infusing a patient's own cells into a heart artery several days after a heart attack speeds the healing process and strengthens the heart's pumping power, researchers report in today's rapid access issue of Circulation: Journal of the AHA.
Air pollution may increase stroke risk
10 Oct 03 | High pollution levels may make people more susceptible to stroke, according to a report in today's rapid access issue of Stroke: Journal of the American Heart Association. Researchers used data on 23,179 hospital stroke admissions.
Nursing home residents, minorities under-treated for recurrent stroke
10 Oct 03 | Only half of elderly Americans in nursing homes are treated to prevent
recurrent strokes, according to a review of nursing home admission records reported in today's rapid access issue of Stroke: Journal of the American Heart Association.
