Two new blood tests for vitamin D are inaccurate in at least 40 percent of laboratory specimens analyzed, a new study finds. The results will be presented Monday at The Endocrine Society’s 94th Annual Meeting in Houston.
For the first time, a study has found that intensive cholesterol therapy involving a combination of drugs for 20 years may be more effective over the long run than taking a single statin medication.
The hot flashes and night sweats that most women experience early in menopause are not linked to increased levels of cardiovascular disease risk markers unless the symptoms persist or start many years after menopause begins. These new study results will be presented Saturday at The Endocrine Society’s 94th Annual Meeting in Houston.
An overactive thyroid gland, or hyperthyroidism, may increase the risk of hospitalization for heart and blood-vessel disease even after surgery to remove the gland, according to a new study. The results will be presented Saturday at The Endocrine Society’s 94th Annual Meeting in Houston.
One in eight people who suffer a heart attack or other acute coronary event experience clinically significant symptoms of PTSD, according to a meta-analysis of 24 studies. The study also shows that heart patients who suffer PTSD face twice the risk of having another cardiac event or of dying within one to three years, compared with those without PTSD.
In a study of more than 1,000 adults, researchers at the University of California, San Diego, found that individuals taking cholesterol-lowering statin drugs are more likely than non-users to experience decreased energy, fatigue upon exertion, or both. The researchers suggest that these findings should be taken into account by doctors when weighing risk versus benefit in prescribing statins.
Researchers at McMaster University have discovered that long-term insulin use does not harm people with diabetes or pre-diabetes or put them at risk of heart attacks, strokes or cancer.
Special echocardiograms show promise for early detection of a potentially deadly complication in rheumatoid arthritis: heart disease, Mayo Clinic research shows.
Researchers from Mount Sinai School of Medicine are pioneering new ultrasound techniques that provide the first characterization of multidirectional blood flow in the heart. By focusing on fluid dynamics – specifically, the efficiency with which blood enters and exits the heart’s left ventricle – the researchers believe they can detect heart disease even when traditional measures show no sign of trouble.
A study led by researchers from McGill University provides new insights into the structure of muscle tissue in the heart – a finding that promises to contribute to the study of heart diseases and to the engineering of artificial heart tissue.
Heart disease risk assessment tools commonly used by physicians often underestimate the cardiovascular disease danger faced by rheumatoid arthritis patients, a Mayo Clinic study has found.

Writing the first commentary for a new feature in the Journal of the American Medical Association (JAMA), called Viewpoint, Johns Hopkins cardiologists make the case for why a 55-year-old man with a 10 percent estimated risk of heart attack over the next 10 years should be offered statin medication. They were invited to debate a professor who argues against prescribing statins for “primary” prevention—for those who have not had a cardiovascular event, such as a heart attack—even though they may be considered at “intermediate” risk because of elevated cholesterol or other factors. Readers are then invited to vote on which viewpoint they endorse.
In a study that included elderly men and women without preexisting cardiovascular disease, major and minor electrocardiographic abnormalities were associated with an increased risk of coronary heart disease (CHD) events and improved the prediction of CHD events such as heart attack, beyond traditional cardiovascular risk factors, according to a study in the April 11 issue of JAMA.
Although observational studies have suggested that losartan, a drug used primarily for the treatment of hypertension, may be associated with an increased risk of death among patients with heart failure compared with other medications in the same class of drugs, an analysis that included nearly 6,500 patients found that overall, use of losartan was not associated with increased all-cause death or cardiovascular death compared with use of the ARB candesartan, according to a study in the April 11 issue of JAMA.
In work published in the Journal of Clinical Investigation researchers question the wisdom of blocking the DP1 receptor in patients prone to cardiovascular disease, especially those taking niacin.

A research network led by a Mayo Clinic physician found that stem cells derived from heart failure patients’ own bone marrow and injected into their hearts improved the function of the left ventricle, the heart’s pumping chamber. Researchers also found that certain types of the stem cells were associated with the largest improvement and warrant further study.

Cigarette smoke has long been considered the main risk factor for heart disease. But new research, to be presented at the 56th Annual Meeting of the Biophysical Society, shows that nicotine itself can contribute to the disease process.
During Heart Disease Awareness Month, experts at the U-M Cardiovascular Center are available to discuss new strategies for improving patient care and the quality of patients’ lives. While cutting-edge techniques are transforming treatment of heart disease, there are ways to prevent getting heart disease in the first place.
Heart disease is the leading cause of death for both men and women in the U.S. However, calcium scoring can give you the winning edge. Michael Pressel, MD from the Heart Center at Sinai Hospital of Baltimore explains.
Being proactive about heart health can help men lower their risk and avoid a heart event.
Heart disease kills more women, young and old, than cancer. Yet for most, it’s avoidable with a healthier lifestyle.

Doctors at the Peter Munk Cardiac Centre today performed a minimally invasive surgical procedure to treat high blood pressure, called renal denervation, for the first time in Canada. The procedure can significantly reduce high blood pressure in patients who cannot effectively treat their hypertension through drugs. These patients, numbering approximately 250,000 Canadians, have to endure an especially high risk of heart attacks and stroke, which continues to kill thousands of Canadians every year.
The risk for heart-related death is increasing in young adults ages 35 to 54, and the numbers are even more alarming for younger women. It is the number-one cause of death for both men and women in the United States, yet every year since 1984 more women have died of cardiovascular health problems than men, according to the American Heart Association.
Patients with coronary artery disease -- blockages of the vessels that feed the heart -- can be treated in a number of ways. With their doctor, they decide on the best course of action: surgery, stent placement or medication. Sometimes, a combination of these is the best approach.
