Researchers have discovered how high glucose levels -- whether caused by diabetes or other factors -- keep heart cells from maturing normally. Their findings help explain why babies born to women with diabetes are more likely to develop congenital heart disease.
High-intensity exercise three times a week is safe for individuals with early-stage Parkinson’s disease and decreases worsening of motor symptoms, according to a new phase 2, multi-site trial.
The presence of death receptors in the blood can be used to directly measure the risk of developing cardiovascular diseases and type 2 diabetes, scientists have discovered.
A new article outlines how modern non-invasive examinations using state-of-the-art imaging technology can reduce the risk of not-detecting infections of the heart muscle possibly leading to chronic inflammations and sudden death.
Although obesity is a well-known risk factor for getting cardiovascular disease, a controversial body of research suggests that obesity may actually be associated with improved survival among people who have cardiovascular disease. However, a new study finds that the 'obesity paradox' is not present among people with new cases of cardiovascular disease.
A recent study finds that a 45-minute online sexual health program improved the ability of teen girls to communicate effectively about safe sex.
Exposure to air pollution on city streets is enough to counter the beneficial health effects of exercise in older adults, according to new research.
Hot flashes, undoubtedly the most common symptom of menopause, are not just uncomfortable and inconvenient, but numerous studies demonstrate they may increase the risk of serious health problems, including heart disease. A new study suggests that hot flashes (especially when accompanied by night sweats) also may increase the risk of developing diabetes.
Reducing a protein found in the mitochondria of cardiac muscle cells initiates cardiac dysfunction and heart failure, a finding that could provide insight for new treatments for cardiovascular diseases, a study has shown.
Scientists have created zebrafish mutants in four different receptors -- found inside or on the surface of cells -- that respond to estrogens, and they have used the mutants to help unravel a novel mechanism of estrogen action on heart physiology. Broader use of the mutants may have significant implications for studies of estrogenic environmental endocrine disruptors.
Patients with congenital heart disease are up to 85 times more likely to suffer from atrial fibrillation as adults. The researchers behind a study are now advocating more frequent screenings of the most vulnerable groups.
Blood pressure in the elderly begins to decrease about 14 or so years before death, according to a new study. Researchers looked at the electronic medical records of 46,634 British citizens who had died at age 60 or older. Blood pressure declined over the last 14 to 18 years of life in both healthy elders and those with serious health problems.
Physicians have successfully implanted a left ventricular assist device with an internal power cable tunneled through the neck to the head in a patient who was ineligible for a cardiac transplantation, destination therapy (DT) trial.
Higher risk of dying due to heart cell damage without any symptoms occurs during or after non-heart surgery
One in seven patients 65 or older undergoing non-heart surgery experienced heart cell damage during or after surgery, known as perioperative myocardial injury (PMI). Deaths of patients with PMI were six times higher in the 30 days following surgery compared to patients without PMI.
Men who suffer symptoms from varicoceles, enlarged veins in the scrotum, are more likely to develop vascular disease and metabolic disease, such as diabetes, according to a study.
How can damaged cardiac tissue following a heart attack best be treated with replacement muscle cells? A research team is now presenting an innovative method on mice: Muscle replacement cells, which are to take over the function of the damaged tissue, are loaded with magnetic nanoparticles. These cells are then injected into the damaged heart muscle and held in place by a magnet, causing the cells to engraft better onto the existing tissue.
A new targeted treatment could benefit patients with certain pancreatic tumors by preventing spread of the cancer and protecting their heart from damage -- a direct result of the tumor. Higher levels of serotonin among other tumor secretions can cause injury to the valves of the heart over time, leading to cardiac impairment -- a condition referred to as cardiac carcinoid disease -- in these patients.
Male-pattern baldness and premature greying are associated with a more than fivefold risk of heart disease before the age of 40 years, according to new research. Obesity was associated with a fourfold risk of early heart disease.
People with diabetes and high risk of CVD who achieved extremely tight glycemic control showed higher risks of fatal heart attacks, a new study has found. Now scientists have identified two genetic variants associated with a threefold increase in CVD in this group. This discovery could lead to easy identification of individuals at risk and treatment using currently approved medications.
Researchers have used mouse models to demonstrate a new approach to restart cardiomyocyte replication after a heart attack: an injectable gel that slowly releases short gene sequences known as microRNAs into the heart muscle.
