Body Weight and Heart Health – Tufts

Eat less; move more; live longer remains the mantra of this blog. Following is a super discussion of the relationship between body weight and heart health from Tufts Health & Nutrition Letter.

Human Heart

Excess body weight increases risk for cardiovascular disease (CVD), as well as type 2 diabetes, certain cancers, and many other illnesses. However, not everyone who is overweight or obese develops these illnesses; and simply having a “normal” body weight or body mass index (BMI)-a measure of body weight relative to height-is no guarantee of low risk. “The relationship between BMI and risk for CVD and death is complex,” says Edward Saltzman, MD, academic dean for education at Tufts’ Friedman School of Nutrition Science and Policy. “Elevated BMI does increase CVD risk, but risk is also impacted by things like body-fat percentage, waist circumference, age, duration of obesity, race, ethnicity, gender, and other genetic factors,” as well as lifestyle elements such as smoking and level of physical activity.

Better lifestyle habits help management of atrial fibrillation- AHA

How many times and how many ways do we have to hear that keeping our weight under control and being physically active are good for us? Eat less; move more; live longer.

Weight loss, regular physical activity and other lifestyle changes are effective yet underused strategies that should be added to optimize management of atrial fibrillation (an abnormal heart rhythm), according to “Lifestyle and Risk Factor Modification for Reduction of Atrial Fibrillation,” a new Scientific Statement from the American Heart Association published in the Association’s flagship journal Circulation.

Atrial fibrillation (AF) is an abnormal heart rhythm that affects at least 2.7 million people in the United States and is increasing as the population grows older. In AF, the upper chambers of the heart, called the atria, beat rapidly and erratically, interfering with proper movement of blood through the chambers, which can allow blood clots to form. Parts of these clots can break off and flow to the brain, causing an ischemic stroke. People who have AF have a five-fold greater risk of having a stroke compared to people without the condition.

To reduce stroke risk in their patients, health professionals use medications or procedures to regulate the heart rate, prevent abnormal heart rhythms (AF) and reduce blood clotting. Continue reading

Preventing Heart Disease – Harvard

Heart disease is the leading cause of death for men, women, and people of most racial and ethnic groups in the United States. One person dies every 37 seconds in the United States from cardiovascular disease. About 647,000 Americans die from heart disease each year—that’s 1 in every 4 deaths.

The following is from the T.H. Chan School of Public Health at Harvard.

When heart experts talk about prevention, they usually refer to one of three types: secondary, primary and primordial prevention. [1] All three have similar elements, but different starting times and different effects.

Despite the power of individual behavior change, it must be noted that unfavorable eating patterns are driven by a variety of biological, social, economic, and psychological factors. This is acknowledged in a 2018 review paper, which recommends that “governments should focus on cardiovascular disease as a global threat and enact policies that will reach all levels of society and create a food environment wherein healthy foods are accessible, affordable, and desirable.” [22] The central illustration of the paper (below) highlights several policy strategies that may help boost healthy eating, such as improving nutrition labels, regulating food marketing, and promoting healthy school and work environments.

Resting heart rate matters… Study

I love my Apple Watch and have written several posts about how it helps me to keep fit. Now comes a study from Scripps that makes me feel even better about it. You can read further about the watch on my Page – How my Apple Watch promotes my good health.

If you wear a smart watch or fitness tracker, you’re likely capturing an important but currently underused vital sign—resting heart rate—that soon may serve as a valuable window into your health, according to new study by the Scripps Research Translational Institute.

In a heart study of unprecedented scale, researchers evaluated the resting heart rate of more than 92,000 individuals for over 32 million days using de-identified data from wrist-worn devices. The scientists found that average resting heat rate varied widely between individuals, with norms that differed by up to 70 beats per minute. Less than 10 percent of the variability could be attributed to expected factors such as age, sex, body mass index or daily sleep duration. However, for individuals, resting heart rate was much more consistent over the two-year study period, with infrequent episodes outside of their norms.

Romance can be good for your heart health …

If you find yourself caring about a certain someone, there is a chance that you will care more about your own heart health. So says, the Cleveland Clinic.

As Valentine’s Day approaches, a Cleveland Clinic survey finds that two-thirds of Americans (66%) in a committed relationship are concerned with their partner’s heart health. Moreover, 60% of Americans say they are more motivated to live a heart healthy lifestyle for their partners than for themselves. This is especially true for men – 67% compared to 52% for women.

The survey was conducted as part of Cleveland Clinic Heart, Vascular and Thoracic Institute’s “Love your Heart” consumer education campaign in celebration of American Heart Month. It looked at how relationships affect heart health. Continue reading

Link seen between cholesterol levels and risk of heart disease and stroke

The most comprehensive analysis of its kind suggests that there is a strong link between non-HDL cholesterol levels and long-term risk for cardiovascular disease in people aged under 45 years, not just at older ages., according to The Lancet.

  • Study is the most comprehensive analysis of long-term risk for cardiovascular disease related to non-high-density lipoprotein (non-HDL) cholesterol – including almost 400,000 people from 19 countries who were followed for up to 43.5 years (median 13.5 years follow-up) between 1970 to 2013.
  • This longer-term evidence may be particularly important in people aged under 45 years.
  • Depending on cholesterol level and number of cardiovascular risk factors, men and women aged under 45 years have a 12-43% or 6-24% risk (respectively) of having fatal or non-fatal heart disease or stroke by the age of 75 years.
  • If non-HDL cholesterol levels were halved, women and men younger than 45 years with starting levels of non-HDL cholesterol between 3.7-4.8 mmol/liter and who had two additional cardiovascular risk factors could reduce their risk from around 16% to 4%, and from around 29% to 6%, respectively.

The observational and modelling study which used individual-level data from almost 400,000 people, published in The Lancet, extends existing research because it suggests that increasing levels of non-HDL cholesterol may predict long-term cardiovascular risk by the age of 75 years. Past risk estimates of this kind are based on 10-year follow-up data.

Exercise benefits your heart, despite your age …

Eat less; move more; live longer – no matter how old you are. Yes, the mantra of this blog applies to all of us, especially the old and out of shape …

A new study in the Canadian Journal of Cardiology showed that older individuals have the most to gain and may gain the most from rehabilitation programs, but this need is often ignored.

Study finds human hearts evolved for endurance

This blog has evolved  over the nine years I have been writing it.  Starting as a men’s weight-loss helper, it has developed into a general good health and long life messenger. I have also learned along the way about certain physical dangers that are not at once obvious. I think I am most concerned with the dangers of a sedentary lifestyle. It’s possibly that being sedentary does a person more damage than smoking. This seems particularly insidious to me as when folks retire, they think about ‘taking it easy.’ Big mistake. One specific aspect of that is prolonged sitting. Check out my Page – The dangers of too much sitting for more details.

Major physical changes occurred in the human heart as people shifted from hunting and foraging to farming and modern life. As a result, human hearts are now less “ape-like” and better suited to endurance types of activity. But that also means those who lead sedentary lives are at greater risk for heart disease. Those are the main conclusions from a unique study led by Aaron L. Baggish, MD, director of the Massachusetts General Hospital (MGH) Cardiovascular Performance Program. Baggish and his collaborators examined how ape hearts differ from those of humans, why those differences exist and what that means to human health. Continue reading

Gain years keeping heart disease at bay – AHA

Heart disease is the nation’s No. 1 cause of death, killing about 650,000 people every year. Life expectancy is cut short by the disease and the health problems that stem from it. But by how much – and what can people do to take those years back?

Screen Shot 2019-08-11 at 8.55.46 PM.png

For heart attacks alone, more than 16 years of life are lost on average, according to American Heart Association statistics. Researchers estimate people with heart failure lose nearly 10 years of life compared to those without heart failure.

“In the past few years, there have been tremendous gains in reducing cardiovascular disease and increasing life expectancy, but we’ve hit a plateau,” said Paul Muntner, an epidemiologist at the University of Alabama at Birmingham.

Some people are at greater risk than others.

African Americans, for example, are more likely to have high blood pressure, obesity and diabetes, and they live 3.4 years less than their white counterparts. Among the six largest Asian American subgroups, research shows Asian Indian, Filipino and Vietnamese populations lose the most years of life to heart disease – up to 18 years for some – compared with white people.

The risk of early death also is high for people with a history of diabetes, stroke and heart attack. Reporting in the Journal of the American Medical Association in 2015, researchers found people with all three conditions had their life expectancy cut by 15 years compared to those without any of the health problems. Even having just two of the conditions reduced life expectancy by 12 years.

But there is hope. Continue reading

DASH Diet can reduce heart failure risk in people under 75

First of all, just what is the DASH Diet? The healthy DASH diet plan was developed to lower blood pressure without medication in research sponsored by the US National Institutes of Health, Dietary Approaches to Stop Hypertension (DASH).
The DASH diet emphasizes the eating of fruits, vegetables, nuts, whole grains, poultry, fish, and low-fat dairy products while reducing consumption of salt, red meat, sweets and sugar-sweetened beverages. It is similar to the Mediterranean diet but differs in recommending low-fat dairy products and excluding alcoholic beverages.

A diet proven to have beneficial effects on high blood pressure also may reduce the risk of heart failure in people under age 75, according to a study led by researchers at Wake Forest School of Medicine, part of Wake Forest Baptist Health.

 

The observational study of more than 4,500 people showed that those individuals under 75 who most closely adhered to the DASH Diet had a significantly lower risk of developing heart failure than those whose eating habits were least in keeping with the diet.

The research is published in the current online issue of the American Journal of Preventive Medicine. Continue reading

Push-ups and heart health – Harvard

Active, middle-aged men able to complete more than 40 push-ups had a significantly lower risk of cardiovascular disease (CVD) outcomes—including diagnoses of coronary artery disease and major events such as heart failure—during 10 years of follow-up compared with those who were able to do less than 10 push-ups during the baseline exam.

“Our findings provide evidence that push-up capacity could be an easy, no-cost method to help assess cardiovascular disease risk in almost any setting. Surprisingly, push-up capacity was more strongly associated with cardiovascular disease risk than the results of submaximal treadmill tests,” said first author Justin Yang, occupational medicine resident in the Department of Environmental Health at Harvard T.H. Chan School of Public Health.

The study was published February 15, 2019 in JAMA Network Open.

Objective assessments of physical fitness are considered strong predictors of health status; however, most current tools such as treadmill tests are too expensive and time-consuming to use during routine exams. This is the first known study to report an association between push-up capacity and subsequent cardiovascular disease outcomes.

The researchers analyzed health data from 1,104 active male firefighters collected from 2000 to 2010. Their mean age was 39.6 and mean body mass index (BMI) was 28.7. Participants’ push-up capacity and submaximal treadmill exercise tolerance were measured at the start of the study, and each man subsequently completed annual physical examinations and health and medical questionnaires.

During the 10-year study period, 37 CVD-related outcomes were reported. All but one occurred in men who completed 40 or fewer pushups during the baseline exam. The researchers calculated that men able to do more than 40 push-ups had a 96% reduced risk of CVD events compared with those who were able to do less than 10 push-ups. Push-up capacity was more strongly associated with lower incidence of cardiovascular disease events than was aerobic capacity as estimated by a submaximal treadmill exercise test.

Because the study population consisted of middle-aged, occupationally active men, the results may not be generalizable to women or to men of other ages or who are less active, note the authors.

“This study emphasizes the importance of physical fitness on health, and why clinicians should assess fitness during clinical encounters,” said senior author Stefanos Kales, professor in the Department of Environmental Health at Harvard Chan School and chief of occupational medicine at Cambridge Health Alliance.

Heart structure and function may change for overweight young adults – AHA

Eat less’ move more; live longer – and, we might add, the sooner the better, according to the latest information from the American Heart Associaton.

Being overweight may cause higher blood pressure and changes to the heart’s structure, even in young adults.

Even as a young adult, being overweight may cause higher blood pressure and thicken heart muscle, setting the stage for heart disease later in life, according to new research in the American Heart Association’s journal Circulation.

The study is the first to explore if higher body mass index (BMI) – a weight-for-height index – results in adverse effects on the cardiovascular system in young adults.

While observational studies can suggest associations between risk factors or lifestyle behaviors and heart disease, they cannot prove cause-and-effect. Here, investigators triangulated findings from three different types of genetic analysis to uncover evidence that BMI causes specific differences in cardiovascular measurements. Continue reading

Music and heart health – Harvard

As a lifetime music lover, I was pleased to read this item on it value in the Harvard Health Blog by Julie Corliss, Executive Editor, Harvard Health Letter. One of my happiest discoveries in the past few years was a blue tooth speaker on a water bottle. I have my choice of over 1000 tunes on my iPhone to accompany me on the bike. Riding to music beats my previous soundless rides.

What’s your “cheer up” song? That question popped up on a recent text thread among a few of my longtime friends. It spurred a list of songs from the ‘70s and ‘80s, back when we were in high school and college. But did you know that music may actually help boost your health as well as your mood?

pexels-photo-534283.jpeg

Music engages not only your auditory system but many other parts of your brain as well, including areas responsible for movement, language, attention, memory, and emotion. “There is no other stimulus on earth that simultaneously engages our brains as widely as music does,” says Brian Harris, certified neurologic music therapist at Harvard-affiliated Spaulding Rehabilitation Hospital. This global activation happens whether you listen to music, play an instrument, or sing — even informally in the car or the shower, he says. Continue reading
