Wearing a continuous positive airway pressure device helps heart failure patients with obstructive sleep apnea get a good night's rest

Wearing a continuous positive airway pressure (CPAP) device not only helps heart failure patients with obstructive sleep apnea get a good night's rest, it lowers blood pressure and heart rate well into the morning, apparently, by reducing sympathetic nervous system activity, according to a new study (PDF) in the June 21, 2005, issue of the Journal of the American College of Cardiology.

Insulin resistance drug with anti-inflammatory effects reduces risk factors

A drug, which reduces insulin resistance and also may have anti-inflammatory and other effects on blood vessels, lowered cardiovascular risk factors in patients with diabetes more than another diabetes medicine, even though both drugs improved blood sugar control equally, according to a new study (PDF) in the June 21, 2005, issue of the Journal of the American College of Cardiology.

Fish may help prevent heart failure as well as heart attacks

Older people who ate fish once or twice a week had a 20 percent lower risk of developing congestive heart failure during 12 years of follow-up, according to a new study (PDF) in the June 21, 2005, issue of the Journal of the American College of Cardiology.

Pioneering new thyroid treatment

The doctor has developed a revolutionary technique for treating hyperthyroidism, also known as Graves' Disease. And earlier this month, Culham became the first person in North America to undergo the new procedure.

Vascular disease most common cause of male erectile dysfunction

A preeminent cardiologist reports, for the first time in a large prospective study, that certain of his patients with erectile dysfunction (ED) and heart problems can now safely use erection drugs that help up to 80% of men restore function and quality of life.

New study finds many concerns with clinical trials

A new study led by OHRI Scientist and University of Ottawa Professor, Dr. Dean Fergusson, has looked at current practices in justifying the conduct of clinical trials and found many concerns. For starters, the report notes, some researchers don't even look at existing evidence, repeating trials that have already been conducted and scientifically validated.

New Zealand Ministry of Health warns Influenza B can be serious health risk to children and young people

A currently-circulating strain of influenza has not been common in New Zealand since 1987 and means children and young people can be at particular risk of serious illness, the Ministry of Health says.

New research tool replicates extreme environmental conditions to help understand the human body's response to everyday stresses

A new research tool will allow University of Oregon scientists to replicate an extreme range of environmental conditions in their quest to test and understand the human body's response to everyday stresses.

New cardiovascular drug derived from Dan Shen (Saliva miltiorrhiza)

Through a large number of clinical trials over the past 3 years, researchers from the CAS Shanghai Institute of Materia Medica (SIMM) have developed a new cardiovascular drug with a definite effective component extracted from Dan Shen (Saliva miltiorrhiza), a medicinal herb widely used in China.

Researchers use PET/CT for molecular imaging of the heart

For the first time, researchers used positron emission tomography (PET)/computed tomography (CT) for imaging the subcellar function of the heart - from its subcellular function to its morphologic appearance. The results of the study were reported at the Society of Nuclear Medicine's 52nd Annual Meeting June 18–22 in Toronto.

Obesity is associated with an impairment of coronary circulatory function

A team of University of California, Los Angeles researchers found that positron emission tomography (PET) can provide important information on the relationship between heart function and obesity. Their findings were reported at the Society of Nuclear Medicine's 52nd Annual Meeting June 18–22 in Toronto.

Cyr61 gene transfer appears potent in stimulation of myocardial angiogenesis

French scientists, examining the possibility of using nuclear medicine with gene therapy to fight heart diseases, reported their findings at the Society of Nuclear Medicine's 52nd Annual Meeting June 18–22 in Toronto.

Elevated C-reactive protein can foil diet's ability to lower cholesterol

If you have high levels of C-reactive protein (CRP), a marker in blood for inflammation that is strongly associated with heart disease, trying to lower your LDL-cholesterol through modest diet changes alone may not work.

Researchers use novel cocktail of cells to coax muscle tissue to develop its own vascular network

For years, a major obstacle has dashed the hopes of creating "replacement parts" for the human body: the lack of an internal, nourishing blood system in engineered tissues. Without it, thicker tissues can't thrive, which has confined tissue engineering's practical application to thin skin, which can recruit blood vessels from underlying tissue.

Many pitfalls of aging result from either older stem cells or stem cells responding to their older environment

Older people are more prone to infections and have a higher risk of developing leukemia, and now researchers at Stanford University School of Medicine have one hint as to why that may be.

Patients who need PET/CT scans should avoid drinking coffee

Patients who need a positron emission tomography (PET)/computed tomography (CT) procedure to evaluate known or suspected malignancies should lay off the java, according to research by Medhat M. Osman, M.D., Ph.D., assistant professor in the department of internal medicine's division of nuclear medicine and director of PET at Saint Louis University Hospital.

Study finds better long-term outcomes when surgeons place a bypass graft to all the territories of the heart that have significantly blocked arteries

Pointing out that not all coronary artery bypass operations are performed the same way or have equivalent outcomes, cardiothoracic surgeons at Cedars-Sinai Medical Center have found that patients who have blockages of multiple coronary arteries and undergo "complete revascularization" - grafting of arteries to restore blood flow to all affected territories of the heart - have consistently better long-term survival rates than those who have "incomplete revascularization."
