Owning a pet may help maintain a healthy heart, especially if that pet is a dog, according to a new analysis. The study examines the association of pet ownership -- specifically dog ownership -- with cardiovascular disease risk factors and cardiovascular health.
Heavily polluted areas have a higher rate of angioplasty procedures to treat blocked arteries than areas with clean air, according to new research. Procedures are even more common in winter, the most polluted time of year.
Women who have heart attacks experience the same key symptoms as men, quashing one of the reasons given for women receiving unequal care. The research puts into question a long-held medical myth that women tend to suffer unusual or 'atypical' heart attack symptoms, and emphasizes the need for both sexes to recognize and act on the warning signs.
Type 2 diabetes may affect heart structure and increase complications and death among heart failure patients of Asian ethnicity
The combination of heart failure and Type 2 diabetes can lead to structural changes in the heart, poorer quality of life and increased risk of early death, according to a multi-country study in Asia.
Heavy cigarette smokers with at least a 20 pack-year smoking history can reduce their risk of cardiovascular disease (CVD) by 39% within five years if they quit, according to a new study.
A new finding has changed the understanding of the molecular mechanisms leading to atrial fibrillation.
A Penn study reveals single instance of vaping immediately leads to reduced vascular function.
Researchers have presented a model that explains why memory deteriorates as the body ages. With age, the brain receives an increased load from the heart's beating as the body's large arteries stiffen over the years, causing damage to the smallest blood vessels in the brain.
A researcher has found that blood vessels within bone marrow may progressively convert into bone with advancing age.
Cutting off and then restoring blood supply to a limb following a stroke reduces tissue damage and swelling and improves functional recovery, according to a new study.
Data from more than a million people found that genetic liability to insomnia may increase the risk of coronary artery disease, heart failure and stroke. Among types of ischemic stroke, genetic liability to insomnia was primarily associated with an increased risk of large artery stroke.
Reparative medicine scientists have discovered a new compound that could shield heart tissue before a heart attack, as well as preserve healthy cells when administered after a heart attack.
Four grams per day of prescription omega-3 fatty acid medication effectively lower high triglyceride levels, but identification of secondary causes of high triglycerides, such as hypothyroidism and poorly managed type 2 diabetes as well as lifestyle changes should be addressed before prescribing drugs.
The study found that 'silent' covert strokes are actually more common than overt strokes in people aged 65 or older who have surgery.
In a study that spanned two and a half decades and looked at data from more than 4,700 participants, researchers have added to evidence that abnormal blood pressure in midlife persisting into late life increases the likelihood of developing dementia. Although not designed to show cause and effect, the study suggests that maintaining a healthy blood pressure throughout life may be one way to help decrease one's risk of losing brain function.
Stroke survivors who completed a group-based aerobic exercise program, like cardiac rehabilitation, significantly improved their endurance and walking capacity regardless of time since stroke. Mixed forms of aerobic activity and walking had the most benefit for stroke survivors.
For adults with high blood pressure, greater blood pressure control than what's currently considered standard is associated with fewer adverse changes of the brain, which could mean lower risks of dementia and cognitive impairment.
Thin, flexible fibers made of carbon nanotubes have now proven able to bridge damaged heart tissues and deliver the electrical signals needed to keep those hearts beating.
Consuming flavonoid-rich items such as apples and tea protects against cancer and heart disease, particularly for smokers and heavy drinkers, according to new research.
When we race walk, for example, part of our healthy heart muscle may want a little more blood and oxygen, so our tiniest blood vessels send a message upstream to the larger vessels to send more. Researchers have found that a chemical in our bodies known to help blood vessels dilate also sends that signal to the larger blood vessels that more blood is needed.
