In a major scientific review of research on e-cigarettes, scientists found that industry claims about the devices are unsupported by the evidence to date, including claims that e-cigarettes help smokers quit.
Researchers are evaluating whether vitamin D can slow the development of cardiovascular problems in African Americans with diabetes. They are more likely to die from cardiovascular disease than Caucasians with diabetes.
Harvard scientists have merged stem cell and “organ-on-a-chip” technologies to grow, for the first time, functioning human heart tissue carrying an inherited cardiovascular disease. The research appears to be a big step forward for personalized medicine, because it is working proof that a chunk of tissue containing a patient’s specific genetic disorder can be replicated in the laboratory.
In a world-first, researchers have discovered one of the main reasons behind why cancer spreads throughout the body: the help of "bad" cholesterol. The research found that LDL regulates the machinery that controls cell migration.
An antioxidant that targets specific cell structures—mitochondria—may be able to reverse some of the negative effects of aging on arteries, reducing the risk of heart disease, according to a new study by the University of Colorado Boulder.
A futuristic anti-aging approach, variously described and utilized by three different Harvard and Stanford groups this week, may hit the clinic by year’s end. The research all began with “heterochronic parabiosis.” That is, old mice were hooked up to young mice via their circulatory systems— and experienced tissue rejuvenation.
Stem cell therapy can regenerate heart muscle in primates, according to a new study. The scientists on this and related projects are seeking way to repair hearts weakened by myocardial infarctions.
A type of cell that builds mouse hearts can renew itself, researchers report. They say the discovery, which likely applies to such cells in humans as well, may pave the way to using them to repair hearts damaged by disease— or even grow new heart tissue for transplantation.
Scientists have identified one of the molecular pathways that resveratrol, the component of grapes and red wine associated with health benefits, uses to achieve its beneficial action.
Dangerous overnight blood sugar levels often go undetected and cause prolonged periods of heart rhythm disturbances in older patients with Type 2 diabetes and associated heart problems, new research reveals. The findings could offer clues to the mechanism by which low blood sugar levels could contribute to life-threatening changes in heart rhythm.
Large sections of the genome that were once referred to as “junk” DNA have been linked to human heart failure, according to new research. So-called junk DNA was long thought to have no important role in heredity or disease because it doesn’t code for proteins.
Ten years of U.S. data suggest that calorie and fat intake increased among statin users during the decade, an indication that many patients might be abandoning heart-healthy lifestyles and assuming that drugs alone will do the trick, the study authors said.
520 million years ago, the first known animal heart, the heart of an ancient shrimp, was formed. Now, it, and its vascular system, have been found to be more complex than that of modern shrimp, researchers report.
Fibroblasts could offer an alternative to heart transplants for patients with heart disease. Researchers found that the heart cell fibroblast is a close relative to a cardiomyocyte, the cell responsible for a healthy beating heart.
Researchers have developed an ultrasound device that could help identify arterial plaque that is at high risk of breaking off and causing heart attack or stroke.
Working with mice and rabbits, scientists have found a way to block abnormal cholesterol production, transport and breakdown, successfully preventing the development of atherosclerosis, the main cause of heart attacks and strokes and the number-one cause of death among humans.
Imaging of the coronary arteries with computed tomography angiography provides an accurate assessment of arterial plaque and could have a dramatic impact on the management of diabetic patients who face a high risk of heart attacks and other cardiovascular events, according to a new study.
Using reprogrammed skin cells, researchers have for the first time used stem cell techniques to grow fully functional assemblies of the cells that line airways leading to the lungs.
Be sure to pick up a watermelon—or two—at your local grocery store. It could save your life. A new study found that watermelon could significantly reduce blood pressure in overweight individuals both at rest and while under stress.
Young adults with such cardiac risk factors as high blood pressure and elevated glucose levels have significantly worse cognitive function in middle age, according to a new study by dementia researchers at UC San Francisco. The findings bolster the view that diseases like Alzheimer’s develop over an individual’s lifespan and may be set in motion early in life.
Patients with severe ischemic heart disease and heart failure can benefit from a new treatment in which stem cells found in bone marrow are injected directly into the heart muscle, according to research presented at the American College of Cardiology's 63rd Annual Scientific Session.
New guidelines that ease the recommended blood pressure could result in 5.8 million U.S. adults no longer needing hypertension medication. The findings are the first peer-reviewed analysis to quantify the impact of guidelines announced in February by the Eighth Joint National Committee. In a divisive move, the committee relaxed the blood pressure goal in adults 60 years and older to 150/90, instead of the previous goal of 140/90.
Combating the tissue degrading enzymes that cause lasting damage following a heart attack is tricky. Each patient responds to a heart attack differently and damage can vary from one part of the heart muscle to another, but existing treatments can’t be fine-tuned to deal with this variation. Penn researchers have developed a way to address this problem via a material that can be applied directly to the damaged heart tissue.
Analysis of surveys of more than 3.5 million American men and women, administered at some 20,000 health centers across the country—believed to be the largest analysis of its kind ever performed—found that married people, regardless of age, sex, or even cardiovascular risk factors, had significantly less chances of having any kind of cardiovascular disease than those who were single, divorced or widowed.
There's fresh evidence that a lot of young people could be headed for heart trouble. A large study of preteens in Texas found that about one-third of them had borderline or high cholesterol when tested during routine physical exams. The results seem to support recent guidelines that call for every child to have a cholesterol test between 9 and 11.
