Symptoms of cardiovascular problems run the gamut. Some – like chest pain during a heart attack or a droopy face during a stroke – are sudden and severe, while others last years with varying intensity. Factors such as sex, cognitive function and depression can complicate the recognition or diagnosis of symptoms, according to the American Heart Association.
In a new report, experts detail the latest knowledge on cardiovascular disease symptoms with the goal to improve patient care and identify where more research is needed.
“Symptoms are a big part of how we assess a patient when they come to see us in clinic and how we make decisions about what the best treatment is for an individual,” said Megan Streur, a nurse practitioner at the Heart Institute at UW Medical Center in Seattle. “But at the same time, there’s a lot that we still don’t understand about the variability of symptoms in the same condition across different individuals.”
Genes and cardiovascular health each contribute in an additive way to a person’s risk of dementia, U.S. researchers including Sudha Seshadri, MD, and Claudia Satizabal, PhD, of The University of Texas Health Science Center at San Antonio (UT Health San Antonio) reported July 20 in the journal Neurology.
The study was conducted in 1,211 participants in the Framingham Heart Study and involved collaborators from Boston University.
Participants with a high genetic risk score based on common genetic variants, including having an allele called apolipoprotein E (APOE) ε4, were at a 2.6-fold higher risk of developing dementia than subjects who had a low risk score and did not carry the APOE ε4 allele.
Your Body Mass Index (BMI) can be useful in widely spread studies, but you need to be careful about relying too much on it personally. I posted on it previously and you can read Don’t get hung up on your BMI – Body Mass Index for more info.
Young Arnold Schwarzenegger as Conan the Barbarian. Six foot two inches tall, 257 pounds, BMI 33. Not what most of us would call obese.
The following is from the Tufts Health & Nutrition Letter:
Having obesity increases risk for cardiovascular disease and other metabolic conditions such as type 2 diabetes, but a normal BMI also does not guarantee good heart health. Here are tips based on what we know to date about metabolic health and weight: Continue reading →
Researchers have developed a method to estimate cardiorespiratory fitness levels that could be applied to data captured by wearable fitness trackers during activities of daily life. This could facilitate testing for those with low exercise tolerance and may reduce the need for medically supervised fitness testing. The study is published ahead of print in the Journal of Applied Physiology.
Cardiorespiratory fitness is the ability of the cardiovascular and respiratory systems to deliver enough oxygen to the muscles during physical activity. People with low cardiorespiratory fitness may have an increased risk of heart disease, heart attack or stroke. Testing the amount of oxygen the body uses during exercise (VO2max) can assess these risks and may also function as a preventive measure. However, people must typically exercise to exhaustion to measure VO2max, and such testing requires medical supervision and specialized equipment. In addition, it may not be safe for all who need to undergo cardiorespiratory fitness testing to exercise at maximum effort. Methods that use lower intensity exercise (submaximal) do not always provide results as accurate as maximal testing. Continue reading →
A plant-based diet may be key to lowering risk for heart disease. Penn State researchers determined that diets with reduced sulfur amino acids — which occur in protein-rich foods, such as meats, dairy, nuts and soy — were associated with a decreased risk for cardiovascular disease. The team also found that the average American consumes almost two and a half times more sulfur amino acids than the estimated average requirement.
Amino acids are the building blocks of proteins. A subcategory, called sulfur amino acids, including methionine and cysteine, play various roles in metabolism and health.
“For decades it has been understood that diets restricting sulfur amino acids were beneficial for longevity in animals,” said John Richie, a professor of public health sciences at Penn State College of Medicine. “This study provides the first epidemiologic evidence that excessive dietary intake of sulfur amino acids may be related to chronic disease outcomes in humans.” Continue reading →
I have just run across another study that backs up the blog mantra of eat less; move more; live longer and its corollary use it or lose it.
Health experts have warned for years that men and women with excess abdominal fat run a greater risk of developing cardiovascular problems. However, individuals with abdominal or central obesity are not the only ones in danger, according to a new study, reported by Elton Alisson | Agência FAPESP
The study found that physically active men who were not overweight but whose waist-stature ratio (WSR) was close to the risk threshold were also more likely to develop heart disorders than individuals with lower WSRs.Continue reading →
Whether you are pear-shaped or apple shaped depends a lot on your genes it seems.
A recent study from Uppsala University has found that whether you store your fat around the trunk or in other parts of your body is highly influenced by genetic factors and that this effect is present predominantly in women and to a much lower extent in men. In the study, which is published in Nature Communications, the researchers measured how fat was distributed in nearly 360,000 voluntary participants.
“We know that women and men tend to store fat differently — women have the ability to more easily store fat on the hips and legs, while men tend to accumulate fat around the abdomen to a higher extent,” says lead author Mathias Rask-Andersen, Ph.D. and postdoctoral researcher at the department of Immunology, Genetics and Pathology at Uppsala University. “This has been attributed to the effects of sex hormones such as estrogen. But the molecular mechanisms that control this phenomenon are fairly unknown.”
Researchers have discovered evidence that endurance exercise, such as running, swimming, cross-country skiing and cycling, will help you age better than resistance exercise, which involves strength training with weights, as reported in Medical Xpress.
In a study published in the European Heart Journal, researchers in Germany looked at the effects of three types of exercise—endurance training, high intensity interval training and resistance training—on the way cells in the human body age, and they found that endurance and high intensity training both slowed or even reversed cellular aging, but that resistance training did not.

Our DNA is organized into chromosomes in all the cells in our bodies. At the end of each chromosome is a repetitive DNA sequence, called a telomere, that caps the chromosome and protects its ends from deteriorating. As we grow older, the telomeres shorten and this is an important molecular mechanism for cell aging, which eventually leads to cell death when the telomere are no longer able to protect the chromosomal DNA. The process of telomere shortening is regulated by several proteins. Among them is the enzyme telomerase that is able to counteract the shortening process and can even add length to the telomeres.

One of my favorite songs as a kid in the 1940’s was “Don’t fence me in.”
Here are some of the lyrics: Oh, give me land, lots of land under starry skies above
Don’t fence me in
Let me ride through the wide open country that I love
Don’t fence me in
It appears I still feel that way, particularly when it comes to exercise. Working out in the health club really turns me off.
A new report reveals that exposure to green space reduces the risk of type II diabetes, cardiovascular disease, premature death, preterm birth, stress, and high blood pressure.
There seems to be a lot of pro-plant based diet info coming out of late. The old ‘meat and potatoes’ diets we grew up on in the ’50’s are being viewed in some doubt. Attitudes change as we learn more about health benefits. While I don’t mean to equate smoking with eating meat, I remember when my first wife was pregnant with our daughter in the 1960’s she said she was going to quit smoking till the baby was born. I thought that seemed really extreme at the time. These days no sane mom-to-be would consider ‘lighting up.’
Vegetarian, especially vegan, diets are associated with better cardiovascular health, according to a new review published in the journal Progress in Cardiovascular Diseases.
Researchers with the Physicians Committee for Responsible Medicine looked at multiple clinical trials and observational studies and found strong and consistent evidence that plant-based dietary patterns can prevent and reverse atherosclerosis and decrease other markers of cardiovascular disease (CVD) risk, including blood pressure, blood lipids, and weight.

With Thanksgiving looming, this is a great time to reaffirm our resolve to exercise regularly. OR, it is the ideal time to resolve to exercise regularly in the coming year and maybe begin to address physical and weight problems that we have neglected.
Regular readers know that I have posted numerous times on the value of exercise not only for our bodies, but also for our brains. On the top of this page is IMPORTANT FACTS ABOUT YOUR BRAIN.
If you click on that link you can find a page full of blog posts on the subject.
Our ancestors engaged in some serious cardio exercise just to get food. No walking down a supermarket aisle for them.
As an enthusiastic bicycle rider and supporter of the exercise, I was really pleased to see the results of the American Heart Association studies. Here is a summary:
• People who bike regularly, either recreationally or as a way to commute, appear to have a lower risk of cardiovascular illness, according to studies conducted in Denmark and Sweden. • Middle-aged and older Danes who took up biking and stuck with it had a 26 percent lower risk of developing coronary artery disease, compared with non-bikers. • In Sweden, those who regularly biked to work were less likely to develop high blood pressure, high cholesterol, pre-diabetes and obesity — key risk factors for cardiovascular illness.
Here I am riding on Chicago’s Northerly Island in my retirement.
People who bike regularly, either for pleasure or as a way to commute, appear to have a lower risk of cardiovascular disease, according to two separate studies published simultaneously in the American Heart Association’s journal Circulation and Journal of the American Heart Association, the AHA/ASA’s Open Access Journal.

Because low fat diets were the rage for a while, people have become confused about the value and necessity of including fats in their diets. I love coconut oil, a saturated fat. I eat it every day and have a Page of information – Coconut Oil – Why you should include it in your diet on it.
Until recently, when you visited the dairy aisle, chances are you headed straight for the blue carton of milk—the skim milk that is. But recent buzz about dairy fat may cause shoppers to pause in front of the oft-shunned red carton of whole milk or other full-fat dairy products, as research suggests that their relationship to heart health is more complex than was once believed. While most studies to date have focused on the association between dairy fat and cardiovascular risk factors, few have examined the relationship to actual onset of cardiovascular disease.
Drinking three to five cups a day linked to lower risk of arterial plaque.
I enjoy coffee and have some every morning. I drink decaf because I don’t like to introduce unhealthy chemicals like caffeine into my system. That’s just me. I am not trying to proselytize here, just get the facts down, because the latest from the Tufts Health Letter interested me as a coffee drinker and blogger who covers health.
“Scientists may now better understand at least one way in which coffee could help to protect against cardiovascular disease. A large new Korean study reports that people drinking three to five cups of coffee daily were 41% less likely to show signs of coronary artery calcium than non-coffee drinkers. This calcification is an early indicator of the artery-clogging plaques (atherosclerosis) that cause coronary artery disease, which afflicts nearly 16 million Americans. Continue reading →
As essential as B-12 is, it can be tricky to get enough in your diet. Foods that contain B-12 include red meat, organ meats like kidneys and liver, eggs, yogurt, and cheese, and seafood — definitely a problem for vegans or vegetarians. Additionally, many people, especially adults over 50, have trouble absorbing B-12. Commonly prescribed drugs can also cause nutritionally deficiencies, including Vitamin B-12, which have been linked to many health conditions.

Vitamin B-12 is one of the more discussed vitamins and for good reason. It is important for your health overall as it helps several organs and systems in your body function properly, including the brain, the nervous and skeletal systems, DNA replication and energy creation processes.
Let’s take a look at a few reasons why it’s important to make sure you’re getting enough Vitamin B-12.
1. Supports Cardiovascular Health
You’ve probably heard that B-12 is good for cardiovascular health. The way that works is this…
Homocysteine is a protein that naturally forms as a byproduct of your body’s processes. When it builds up, it can corrode and inflame arteries and blood vessels, placing strain on the heart and cardiovascular system. Vitamin B-12 helps converts homocysteine to methionine, a protein the body uses…
