Rapid decreases in resting heart rate from childhood to adulthood may indicate heart trouble ahead

While a slow resting heart rate is generally considered a good thing, investigators have some of the first evidence that if that rate decreases rapidly as children move into young adulthood, it’s an indicator that cardiovascular disease may be in their future.

Medical College of Georgia investigators report a significant association between a faster decrease in resting heart rate from childhood to adulthood and a larger left ventricle, the heart’s major pumping chamber, over a 21-year period in hundreds of individuals who were healthy at the start.

The faster decrease in heart rate also was associated with a higher level of pressure inside the blood vessels of the body, which the heart has to pump against to get blood and oxygen out, they write in the journal Acta Cardiologica. The associations were generally stronger in Blacks.

“An unexplained drop over time is not a good thing,” says Dr. Gaston Kapuku, cardiovascular researcher at MCG’s Georgia Prevention Institute and the study’s corresponding author.

Looking at the resting heart rate at one moment in time, as opposed to how it trends from childhood to adulthood, is not a good thing either, Kapuku says.

What is a Healthy Resting Heart Rate?

One of the most important measurements we can know about ourselves is our resting heart rate. Yet most people don’t know it. They can give you their cholesterol count (usually the total, not the breakdown of HDL and LDL see  post – How to Improve your cholesterol numbers), but unless the person has recently visited his doctor he will be stumped when it comes to his resting heart rate, or its relevance to his overall health..hwkb17_071

WebMD reported, “For most people, a normal resting heart rate is between 60 and 90 beats a minute,” according to Edward F. Coyle, PhD. The professor of kinesiology and health education at the University of Texas at Austin and director of the university’s Human Performance Laboratory, says. “Athletic training can lower that rate by 10 to 20 beats per minute.heart-rate-carotid

“Regular aerobic exercise makes your heart stronger and more efficient, meaning that your heart pumps more blood each time it contracts, needing fewer beats per minute to do its job.”

Edward R. Laskowski, M.D., Mayo Clinic physical medicine and rehabilitation specialist puts the normal resting heart rate between 60 and 100 beats per minute. “Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats a minute.”

The upper end of the range is relevant. Gordon F. Tomaselli, MD, professor of medicine at Johns Hopkins University School of Medicine in Baltimore, told WebMD, “A number of studies have shown that, even within the normal range, a high resting heart rate is associated with an increased risk for ischemic heart disease, stroke, and sudden cardiac death.”

Test Your Fast Food Smarts – Web MD Quiz

I really enjoy the information available from WebMD. They offer articles, studies and quizzes on healthy subjects.

I want to tell you about this recent one – Test Your Fast Food Smarts.
fastfood1
I have been writing this blog for the best part of four years. As a result of this project, I have taken off 15 pounds from what I had thought was my ideal weight 165 pounds. In addition I have a resting heart rate below 50 beats per minute and my body fat remains under 17 per cent. Before I took the quiz I thought I had a really good fix on fast food even though I don’t eat very much of it. However, of the 16 questions in the quiz I got less than half of them right.

Here are a couple of examples of questions in the quiz. I hope they will whet your appetite for more info on the subject.

How many Americans eat fast food every day?

How many of us guzzle sugary drinks daily?

To burn off an order of medium fries, a 155 pound adult needs to? Ride a stationary bike hard for 30 minutes or do high impact aerobics for 30 minutes or strength train for 60 minutes?

On average a teen will grab a fast food meal that has how many calories? 500 to 800; 800 to 1100; 1100 to 1500 calories?

No, I am not going to spoil your fun by giving you any of the answers. I hope you will take the test and derive the full benefit from it. At the risk of using a cliche – You’ll thank me for it.
