When exposed to heat, the body may struggle to function normally, potentially resulting in serious cardiovascular issues. To cool down, the body increases blood flow to the skin, leading to higher heart rates and increased cardiac workloads. The resultant increase in strain on the heart can pose a significant risk for vulnerable groups, including older adults and individuals … [Read more...]

Tiny, Daily Bursts of Vigorous Incidental Physical Activity could Almost Halve Cardiovascular Risk in Middle-Aged Women
An average of four minutes of incidental vigorous physical activity a day could almost halve the risk of major cardiovascular events, such as heart attacks, for middle-aged women who do not engage in structured exercise, according to new research from the University of Sydney, published in the British Journal of Sports Medicine. "We found that a minimum of 1.5 minutes to … [Read more...]
Invention Quickly Detects Earliest Sign of Heart Attack
"Heart attacks require immediate medical intervention in order to improve patient outcomes, but while early diagnosis is critical, it can also be very challenging -- and near impossible outside of a clinical setting," said lead author Peng Zheng, an assistant research scientist at Johns Hopkins University. "We were able to invent a new technology that can quickly and accurately … [Read more...]
Study Proposes New Heart Failure Treatment Targeting Abnormal Hormone Activity
In heart failure, which is considered a global pandemic, the heart can no longer pump blood effectively. In HFpEF, the heart can pump normally but its muscles are too stiff to relax to re-fill the chambers with blood properly. It is often seen in older adults and people with multiple risk factors including high blood pressure (hypertension), obesity and diabetes. They … [Read more...]
Like Father, Like Daughter
When they become fathers, men who have an unhealthy, high-cholesterol diet can cause increased risk of cardiovascular disease, or CVD, in their daughters, a University of California, Riverside-led mouse study has found. The research, published in the journal JCI Insight, is the first to demonstrate this result seen only in female offspring. CVD, the leading cause of death … [Read more...]
Short, Intense Bursts of Exercise More Effective After Stroke than Steady, Moderate Exercise
One-minute, short bursts of high-intensity interval training for 19 minutes may be more effective for improving fitness among people six months or more after a stroke than traditional, 20-30 minutes of moderate-intensity exercise sessions, according to research published today in Stroke, the peer-reviewed scientific journal of the American Stroke Association, a division of the … [Read more...]

Reduced Blood Lead Levels Linked to Lower Blood Pressure
Through the Strong Heart Family Study, National Institutes of Health-supported researchers found that small declines in blood lead levelswere associated with long-term cardiovascular health improvements in American Indian adults. Participants who had the greatest reductions in blood lead levels saw their systolic blood pressure fall by about 7 mm Hg, an amount comparable to the … [Read more...]
Elevated Pregnancy Blood Pressure may Leave Lasting Marks on the Heart
New research from the Smidt Heart Institute at Cedars-Sinai found that women who developed signs of elevated blood pressure during pregnancy were more likely to have residual evidence of abnormal heart structure and function up to a decade after the pregnancy. "This study helps to clarify that, for some women, pregnancy is not just a 'stress test' that unmasks underlying … [Read more...]
Benefits of Adolescent Fitness to Future Cardiovascular Health Possibly Overestimated
There is a well-known relationship between good physical fitness at a young age and a lower risk of cardiovascular disease later in life. However, when researchers adjusted for familial factors by means of sibling analysis, they found a weaker association, although the link between high body mass index (BMI) and cardiovascular disease remained strong. The study, which was … [Read more...]
Measuring Long-Term Heart Stress Dynamics with Smartwatch Data
Biomedical engineers at Duke University have developed a method using data from wearable devices such as smartwatches to digitally mimic an entire week's worth of an individual's heartbeats. The previous record covered only a few minutes. Called the Longitudinal Hemodynamic Mapping Framework (LHMF), the approach creates "digital twins" of a specific patient's blood flow to … [Read more...]
Not Getting Enough Sleep? Your Vascular Cells are Drowning in Oxidants
Does this sound like you? You wake up at the same time each morning, get the kids out the door, and rush to catch the subway to work. But at night, maybe you stay up until midnight doing laundry or 1 a.m. to catch up on the bills. Lots of Americans -- about one-third of us -- are in the same situation and habitually get only five to six hours of sleep instead of the … [Read more...]
Increasing Steps by 3,000 Per Day can Lower Blood Pressure in Older Adults
A new study including Linda Pescatello, distinguished professor of kinesiology in UConn's College of Agriculture, Health and Natural Resources, found that adding a relatively minimal amount of movement, about 3,000 steps per day, can significantly reduce high blood pressure in older adults. Pescatello worked with Elizabeth Lefferts, the lead author of the paper, Duck-chun … [Read more...]
Cold Weather may Pose Challenges to Treating High Blood Pressure
According to the American Heart Association's 2023 Statistical Update, nearly half of adults in the U.S. have high blood pressure. Previous research found that blood pressure varies with the seasons of the year. Most of this variation is in systolic blood pressure -- the top number in a blood pressure reading that gauges the pressure in/against blood vessels during heartbeats. … [Read more...]

How The Flu Virus Hacks Our Cells
Influenza viruses represent a major risk to human and animal health. Their potential for mutation makes them particularly elusive. ''We already knew that the influenza A virus binds to sugar structures on the cell surface, then rolls along the cell surface until it finds a suitable entry point into the host cell. However, we did not know which proteins on the host cell surface … [Read more...]
Women Twice as Likely to Be Re-hospitalized After Heart Attack
Women under 55 are twice as likely as men to be hospitalized again within a year after a heart attack, the National Institutes of Health reported this week. The NIH said in a news release that the disparity is likely the result of higher rates of obesity, heart failure, depression and other risk factors among women. The study was paid for by the National Heart, Lung, and … [Read more...]
Non-Biological Factors and Social Determinants of Health Important in Women’s CVD Risk Assessment
"Risk assessment is the first step in preventing heart disease, yet there are many limitations to traditional risk factors and their ability to comprehensively estimate a woman's risk for cardiovascular disease," said Jennifer H. Mieres, M.D., FAHA, vice chair of the scientific statement writing committee and a professor of cardiology at the Zucker School of Medicine at Hofstra … [Read more...]
Does The Risk of Stroke From Common Risk Factors Change as People age?
"High blood pressure and diabetes are two important risk factors for stroke that can be managed by medication, decreasing a person's risk," said study author George Howard, DrPH, of the University of Alabama at Birmingham School of Public Health. "Our findings show that their association with stroke risk may be substantially less at older ages, yet other risk factors do not … [Read more...]
