Exercise trumps genetics when it comes to heart disease

This is a case of the more the merrier as far as I am concerned. Eat less; move more; live longer is the mantra of this blog. And here, we have fresh research extolling the virtues of exercise in preventing heart disease.

Exercise, especially cardio fitness, could outweigh genetics when it comes to heart disease, according to new research.

The study, published in the journal Circulation, showed strength and cardiorespiratory fitness lowered the risk for heart disease across the board – whether people were categorized with low, intermediate or high genetic risk.

“Genes don’t have to determine destiny,” said Dr. Erik Ingelsson, lead study author and professor of medicine at Stanford University. “You can impact your risk by being more fit.”

I can’t say it enough times – take responsibility for your health. Don’t be blaming problems on your genes.

The study examined 482,702 people in England, Scotland and Wales who participated in the UK Biobank, an international research project that recruited participants between ages 40 and 69 years old from 2006 to 2010. Researchers followed those who didn’t have any signs of heart disease for about a decade. They tracked activity and exercise through questionnaires, grip strength measurements and other tests.

“It’s was a very consistent pattern for all of these different measures,” according to Ingelsson, who said he believes it is the largest such study. “All were associated with lower risk of disease in the future.”

Researchers specifically investigated the genetic profiles for those at highest risk for coronary heart disease and a heart rhythm disorder called atrial fibrillation, or AFib. Those at the highest risk who also had the highest levels of cardiorespiratory fitness – conducted through oxygen and effort measurements on a stationary bicycle – cut their coronary heart disease risk by 49 percent and their AFib risk by 60 percent.

The research is important – and timely, said Dr. Russell Pate, a professor in the University of South Carolina’s Department of Exercise Science in the Arnold School of Public Health.

“They’ve demonstrated that physical activity and fitness were associated with a reduced risk of cardiovascular disease outcomes across a continuum of persons,” Pate said. “For the public, that’s an important message. You can’t eliminate genetic risk, but you can absolutely attenuate the effects.”

Pate just finished a term on a committee that writes the federal Physical Activity Guidelines. The group’s advisory report was released last month and will be the foundation for the U.S. Department of Health and Human Services’ policy recommendations on how physical activity can promote health and reduce the risk of disease. The advisory group’s recommendations have a chapter emphasizing the importance of exercise with people who have chronic conditions.

The latest research is “added ammunition in making the case that promotion of physical activity deserves a prominent place in public health,” Pate said.

Heart disease is the leading cause of death in the world, though there are proven ways to lower risk. People often hear about risk factors such as smoking, high cholesterol, high blood pressure and excess weight. Now, the expanding field of genetics can provide more information, Pate said.

“We’re in a new era in terms of people being able to know their risk status,” he said. “We can now provide information at a new and higher level.”

Ingelsson and the study authors suggested it could lead to individualized strength-training and aerobic programs to help people counteract their genetic risk for heart disease.

But one important question to answer, and a potential future area of study, Ingelsson said, is whether that knowledge truly is power. If we know that lifestyle choices like exercise could offset our genetic risk for disease, how likely are we to start that healthier lifestyle?

Exercise can reverse damage from heart aging – Study

Eat less; move more; live longer. Simple acts with profound effects. And, according to the latest study, don’t wait till you are old to start.

Exercise can reverse damage to sedentary, aging hearts and help prevent risk of future heart failure – if it’s enough exercise, and if it’s begun in time, according to a new study by cardiologists at UT Southwestern and Texas Health Resources.

To reap the most benefit, the exercise regimen should begin by late middle age (before age 65), when the heart apparently retains some plasticity and ability to remodel itself, according to the findings by researchers at the Institute for Exercise and Environmental Medicine (IEEM), which is a collaboration between UT Southwestern Medical Center and Texas Health Presbyterian Hospital Dallas.

And the exercise needs to be performed four to five times a week. Two to three times a week was not enough, the researchers found in an earlier study. Continue reading

Harvard says, ‘Nuts to you’ – for heart health

I am fortunate in that I like nuts in all manner and form. Always have. So, nuts are an integral part of my daily diet.

MW-AU956_smnuts_20121002175526_MG.jpg

Many people think of nuts as just another junk food snack. In reality, nuts are excellent sources of healthy fat, protein, and other healthful nutrients.

One surprising finding from nutrition research is that people who regularly eat nuts are less likely to have heart attacks or die from heart disease than those who rarely eat them. Several of the largest cohort studies, including the Adventist Study, the Iowa Women’s Health Study, the Nurses’ Health Study, and the Physicians’ Health Study have shown a consistent 30 percent to 50 percent lower risk of myocardial infarction, sudden cardiac death, or cardiovascular disease associated with eating nuts several times a week. In fact, the FDA now allows some nuts and foods made with them to carry this claim: “Eating a diet that includes one ounce of nuts daily can reduce your risk of heart disease.” Continue reading

Heart function linked to brain’s memory center – Study

This is fascinating and seems to bolster my thought that exercising the body benefits the brain a great deal. The concept of use it or lose it is widely known and accepted regarding physical development. It seems it also applies to mental makeup.  As above, so below.

Research by a team of Vanderbilt University Medical Center (VUMC) scientists suggests that older people whose hearts pump less blood have blood flow reductions in the temporal lobe regions of the brain, where Alzheimer’s pathology begins.

The brain, which accounts for only 2 percent of total body weight, typically receives 12 percent of blood flow from the heart — a level maintained by complex, automatic processes, which maintain consistent blood flow to the brain at all times.

Angela Jefferson, Ph.D., director of the Vanderbilt Memory and Alzheimer’s Center, and colleagues investigated whether lower cardiac index (the amount of blood flowing out of the heart adjusted for body size) correlated with lower blood flow to the brain.

The purpose of the study was to better understand whether reductions in brain blood flow might explain clinical observations in prior research that have linked heart function to cognitive impairment, Alzheimer’s disease and dementia.

“We currently know a lot about how to prevent and medically manage many forms of heart disease, but we do not yet know how to prevent or treat Alzheimer’s disease,” Jefferson said. Continue reading

Good heart health in middle age improves/extends golden years – AHA

Eat less; move more; live longer remains the mantra of this blog. Now, according to the American Heart Association, the sooner you start, the better.

People with no major heart disease risk factors in middle age live longer and stay healthy far longer than others, according to a 40-year study reported in the American Heart Association’s journal Circulation.

“Good cardiovascular health in middle age delays the onset of many types of disease so that people live longer and spend a much smaller proportion of their lives with chronic illness,” said Norrina Allen, Ph.D., M.P.H., assistant professor of preventive medicine at Northwestern University Feinberg School of Medicine in Chicago.

In the first study to analyze the impact of cardiovascular health in middle age on the duration of illness later in life, researchers examined data from the Chicago Health Association study, which did initial health assessments in the late 1960s/early 1970s and has followed participants on an ongoing basis using Medicare health records. Researchers determined how many participants had favorable factors: non-smokers, free of diabetes and normal weight, blood pressure, and cholesterol levels; versus those with elevated risk factors or high risk factors.

20 Health benefits of the banana – Infographic

The banana is one of the most amazing fruits there is. I was driving in my car one day listening to public radio. There was a fellow being interviewed who had just written a book on the history of the banana. I laughed. What kind of history could it have? Well, it turned out to be so fascinating that I ended up buying the book.

A Healthy Heart = A Healthy Brain

I remember the old cliche when it rains, it pours referring to bad news, but, in fact, the past few days, it seems to have been raining stories on brain development. I think that is great news. This latest one is from the American Heart Association.

A healthy heart may have major benefits for preventing the decline in brain function that sometimes accompanies aging, according to new research in the Journal of the American Heart Association.

8 Reasons to Eat More Mushrooms

“Mushrooms are miniature pharmaceutical factories, and of the thousands of mushroom species in nature, our ancestors and modern scientists have identified several dozen that have a unique combination of talents that improve our health,” says leading mushroom research, Paul Stamets, who has written six books about mushrooms.

Our Better Health

Diana Herrington   February 10, 2015

If you’re looking for a new food to boost your health and shake up your boring meal routine, mushrooms might be it. With over 100 thousand species of mushroom-forming fungi and huge health benefits, the mushroom is a little-known superstar. We often sprinkle mushrooms on our salads or add them to our casseroles. Next time add a few more handfuls of this ingredient–or, better yet, make it the main entree! Including a little more mushroom to your favorite meal is a tasty and rewarding move.

There are:

  • 140,000 species of mushroom-forming fungi.
  • Close to 100 types of mushrooms being studied for their health benefits.
  • A small number found to be very beneficial for boosting your immune system.

Green Vegetables Could Improve Heart’s Efficiency

Commenting on the results, Dr Murray, who worked on all three studies, said: “There have been a great many findings demonstrating a role for nitrate in reducing blood pressure and regulating the body’s metabolism. These studies represent three further ways in which simple changes in the diet can modify people’s risk of type 2 diabetes and obesity as well as potentially alleviating symptoms of existing cardiovascular conditions to achieve an overall healthier life.”

Green veg contains nitrate could improve heart’s efficiency, blood supply to organs and reduce risk of diabetes and obesity

In three independent studies, scientists from the Universities of Southampton and Cambridge have identified how a simple chemical called nitrate, found in leafy green vegetables, can help thin blood ensuring oxygen can be delivered to all corners of the body efficiently. Reducing the thickness of blood may also decrease instances of dangerous clots forming and reduce the risk of stroke and heart attacks.

The same researchers, part-funded by the British Heart Foundation (BHF), also found nitrate can help the diseased heart to function more efficiently, help produce more of a compound that widens and opens blood vessels and help change bad white fat cells into good brown, fat-burning cells, which could combat obesity and reduce risk of type 2 diabetes.

In the first (1) study published this week in the Journal…

Nothing Fishy about Health Benefits of Plant-based Omega-3 Fatty Acid

“Heart disease is the leading cause of death in the country,” said Fleming. “Learning what you can do to prevent heart disease is important and relevant for everybody.”

Cooking with Kathy Man

Increasing the amount of omega-3s in your diet, whether from fish or flax, will likely decrease your risk of getting heart disease, according to Penn State nutritionists.

A substantial amount of evidence exists supporting the heart-health benefits of eicosapentaenoic acid and docosahexaenoic acid (EPA and DHA), marine-derived omega-3 fatty acids. However, much less evidence exists to demonstrate the positive effects of alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid.

“The benefits reported for EPA and DHA are stronger because supplements of EPA and DHA were tested, and EPA and DHA was the only difference between the treatment and control groups,” said Jennifer Fleming, instructor and clinical research coordinator in nutritional sciences. “In contrast, in the ALA studies, there were diet differences beyond ALA between the treatment and control groups.”

EPA and DHA can be found in seafood and fish oil, and are often consumed in the form of dietary supplements…

Aspirin or No Aspirin?

“We estimate that individuals with significant plaque buildup in the arteries of the heart are much more likely to prevent a heart attack with aspirin use than to suffer a significant bleed” explains Miedema. “On the opposite end of the spectrum, if you don’t have any calcified plaque, our estimations indicate that use of aspirin would result in more harm than good, even if you have risk factors for heart disease such as high cholesterol or a family history of the disease.”

Cardiac Screening Test May Help Determine Who Should Take Aspirin to Prevent Heart Attack

A study involving the Minneapolis Heart Institute Foundation shows that a simple test to measure plaque in the arteries of the heart may help doctors better determine who will and will not benefit from use of aspirin therapy to prevent heart disease.

For over 30 years, aspirin has been known to prevent heart attacks and strokes, but who exactly should take a daily aspirin remains unclear. New research published today in Circulation: Cardiovascular Quality and Outcomes shows that your coronary artery calcium (CAC) score, a measurement of plaque in the arteries that feed the heart, may help determine whether or not you are a good candidate for aspirin.

“Many heart attacks and strokes occur in individuals who do not appear to be at high risk,” states lead author, Michael D Miedema, MD, MPH. “Individuals with known…
