Good oral hygiene and regular dental care are the most important ways to reduce risk of a heart infection called infective endocarditis caused by bacteria in the mouth.
There are four categories of heart patients considered to be at highest risk for adverse outcomes from infective endocarditis, and only these patients are recommended to receive preventive antibiotic treatment prior to invasive dental procedures.
American Heart Association (AHA) guidelines issued in 2007 suggested not to use antibiotics before certain dental procedures. These recommendations resulted in a decrease in antibiotic use.
Maintenance of good oral health is more important than use of antibiotics in dental procedures for some heart patients to prevent a heart infection caused by bacteria around the teeth, according to a new American Heart Association (AHA) scientific statement published today in the association’s flagship journal, Circulation.
Infective endocarditis (IE), also called bacterial endocarditis, is a heart infection caused by bacteria that enter the bloodstream and settle in the heart lining, a heart valve or a blood vessel. It is uncommon, but people with heart valve disease or previous valve surgery, congenital heart disease or recurrent infective endocarditis have a greater risk of complications if they develop IE. Intravenous drug use also increases risk for IE. Viridans group streptococcal infective endocarditis (VGS IE) is caused by bacteria that collect in plaque on the tooth surface and cause inflammation and swelling of the gums. There’s been concern that certain dental procedures may increase the risk of developing VGS IE in vulnerable patients.
Psychosocial stress – typically resulting from difficulty coping with challenging environments – may work synergistically to put women at significantly higher risk of developing coronary heart disease, according to a study by researchers at Drexel University’s Dornsife School of Public Health, recently published in the Journal of the American Heart Association.
The study specifically suggests that the effects of job strain and social strain — the negative aspect of social relationships — on women is a powerful one-two punch. Together they are associated with a 21% higher risk of developing coronary heart disease. Job strain occurs when a woman has inadequate power in the workplace to respond to the job’s demands and expectations.
The study also found that high-stress life events, such as a spouse’s death, divorce/separation or physical or verbal abuse, as well as social strain, were each independently linked with a 12% and 9% higher risk of coronary heart disease, respectively.
The Drexel study used data from a nationally representative sample of 80,825 postmenopausal women from the Women’s Health Initiative Observational Study, which tracked participants from 1991 to 2015, to find better methods of preventing cancer, heart disease and osteoporosis in women. In the current follow-up study, Drexel researchers evaluated the effect of psychosocial stress from job strain, stressful life events and social strain (through a survey), and associations among these forms of stress, on coronary heart disease.
It ought to be a no-brainer, so to speak: Research has pinpointed seven ways people can achieve ideal heart and brain health. And – bonus – if Americans did those things, they also could help prevent many other chronic illnesses, According to the American Heart Association News.
But most people don’t, at least not consistently. What’s stopping them?
“Most of these steps require a great deal of self-regulation and self-control,” said Dolores Albarracin, a professor of psychology at the University of Illinois at Urbana-Champaign. “It’s not just getting one thing done, like going to get a vaccine, where you can do it and forget about it for a year.”
Volumes of research point to at least seven behaviors, called Life’s Simple 7, that can dramatically lower the burden of heart disease, stroke and dementia. Not smoking, eating a healthy diet, exercising regularly, maintaining a healthy weight, and keeping blood glucose, blood pressure and cholesterol levels in a healthy range have the potential to collectively wipe out a vast majority of heart disease and stroke and prevent or delay a significant number of dementias.
Increased consumption of flavanols – a group of molecules occurring naturally in fruit and vegetables – could protect people from mental stress-induced cardiovascular events such as stroke, heart disease and thrombosis, according to new research.
Researchers have discovered that blood vessels were able to function better during mental stress when people were given a cocoa drink containing high levels of flavanols than when drinking a non-flavanol enriched drink.
A thin membrane of cells lining the heart and blood vessels, when functioning efficiently the endothelium helps to reduce the risk of peripheral vascular disease, stroke, heart disease, diabetes, kidney failure, tumor growth, thrombosis, and severe viral infectious diseases. We know that mental stress can have a negative effect on blood vessel function.
A UK research team from the University of Birmingham examined the effects of cocoa flavanols on stress-induced changes on vascular function – publishing their findings in Nutrients.
Lead author, Dr. Catarina Rendeiro, of the University of Birmingham’s School of Sport, Exercise and Rehabilitation Sciences, explains: “We found that drinking flavanol-rich cocoa can be an effective dietary strategy to reduce temporary impairments in endothelial function following mental stress and also improve blood flow during stressful episodes”.
“Flavanols are extremely common in a wide range of fruit and vegetables. By utilizing the known cardiovascular benefits of these compounds during periods of acute vascular vulnerability (such as stress) we can offer improved guidance to people about how to make the most of their dietary choices during stressful periods.”
In a randomized study, conducted by postgraduate student Rosalind Baynham, a group of healthy men drank a high-flavanol cocoa beverage 90 minutes before completing an eight-minute mental stress task.
The researchers measured forearm blood flow and cardiovascular activity at rest and during stress and assessed functioning of the blood vessels up to 90 min post stress – discovering that blood vessel function was less impaired when the participants drank high-flavanol cocoa. The researchers also discovered that flavanols improve blood flow during stress.
Stress is highly prevalent in today’s society and has been linked with both psychological and physical health. Mental stress induces immediate increases in heart rate and blood pressure (BP) in healthy adults and also results in temporary impairments in the function of arteries even after the episode of stress has ceased.
Single episodes of stress have been shown to increase the risk of acute cardiovascular events and the impact of stress on the blood vessels has been suggested to contribute to these stress-induced cardiovascular events. Indeed, previous research by Dr Jet Veldhuijzen van Zanten, co-investigator on this study, has shown that people at risk for cardiovascular disease show poorer vascular responses to acute stress.
“Our findings are significant for everyday diet, given that the daily dosage administered could be achieved by consuming a variety of foods rich in flavanols – particularly apples, black grapes, blackberries, cherries, raspberries, pears, pulses, green tea and unprocessed cocoa. This has important implications for measures to protect the blood vessels of those individuals who are more vulnerable to the effects of mental stress,” commented Dr. Rendeiro.
I have to confess that I love the taste of fried food. I don’t eat a lot of it for health reasons, but few foods taste more delicious to me.
Fried-food intake is linked to a heightened risk of major heart disease and stroke, finds a pooled analysis of the available research data, published online in the journal Heart.
And the risk rises with each additional 114 g (4.02 ounces) weekly serving, the analysis indicates.
It’s clear that the Western diet doesn’t promote good cardiovascular health, but it’s not clear exactly what contribution fried food might make to the risks of serious heart disease and stroke, say the researchers.
To shed some light on this, they trawled research databases, looking for relevant studies published up to April 2020, and found 19.
A growing body of research suggests heart attacks, angina and other heart events increase during winter and summer.
Now, a new study could explain why.
Researchers reviewed an international registry of 1,113 people, the majority from Japan, with acute coronary syndrome. Heart attack is a type of acute coronary syndrome, which occurs when the blood supply to the heart muscle is suddenly decreased or blocked.
Using images of the fatty deposits in participants’ coronary arteries, researchers put people into groups: plaque rupture, plaque erosion and calcified plaque. Each plaque scenario can block blood flow and lead to a heart attack or other cardiac event. But a rupture is more immediate and occurs when the calcified plaque breaks off. Erosion can happen over time.
“We looked at those three underlying mechanisms to see whether they were different among the different seasons. As expected, we found a significant difference,” said Dr. Ik-Kyung Jang, lead author of the study published Thursday in the Journal of the American Heart Association. Jang is an interventional cardiologist and director of the Cardiology Laboratory of Integrated Physiology and Imaging at Massachusetts General Hospital in Boston.
The body starts to respond to healthy dietary changes as soon as they are made. This can be advantageous, because a diet can then eventually reduce the risk of obesity, diabetes and heart disease, as well as improve a person’s overall sense of well being.
Control of blood glucose level
Eating carbohydrates increases the blood sugar level, but the extent of this rise depends on a food’s glycemic index. The glycemic index is a ranking system, based on a score of 1 to 100, that determines the effect of a food on blood sugar levels.
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.  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.”  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.Continue reading →
In the nearly 10 years I have been writing this blog, I have written numerous posts on stress. I even have a Page – How to deal with stress with a number of them listed if you want to read further on it. What follows here is from the American Heart Association.
Sometimes stress can be useful. But constant stress can affect overall well-being and may even impact heart health.
When stress is short-lived, it can help with performance in meeting a major deadline, interviewing for a new job or achieving another goal. Stress and its impact on the body can also be lifesaving in the face of danger. Continue reading →
Most people realize getting medical help quickly is crucial in response to a heart attack or stroke. But you need to know the signs so you can act, according to the American Heart Association.
“It is an emergency. People need to call 911,” said Dr. Erin Michos, associate director of preventive cardiology at the Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease in Baltimore.
Emergency medical responders can begin evaluating a potential heart attack or stroke, and start treatment before arriving at a hospital, she said.
Heart disease is the nation’s leading killer, and every 40 seconds someone has a heart attack. Continue reading →
A new study finds that heart disease may increase your chances of kidney failure.
• In adults followed for a median of 17.5 years, cardiovascular diseases—including heart failure, atrial fibrillation, coronary heart disease, and stroke—were each linked with a higher risk of developing kidney failure.
• Heart failure was associated with the highest risk: adults hospitalized with heart failure had an 11.4-times higher risk of developing kidney failure than individuals without cardiovascular disease
New research indicates that cardiovascular diseases—including heart failure, atrial fibrillation, coronary heart disease, and stroke—are each linked with a higher risk of developing kidney failure. The findings, which appear in an upcoming issue of the Journal of the American Society of Nephrology, highlight the importance of protecting the kidney health of individuals diagnosed with cardiovascular disease.
The heart and the kidneys have a bi-directional relationship, whereby dysfunction in either may compromise the function of the other. Many studies have investigated the risks of kidney disease on heart health, but few have examined the reciprocal relationship.
To investigate, a team led by Kunihiro Matsushita, MD, PhDand Junichi Ishigami, MD, PhD(Johns Hopkins Bloomberg School of Public Health)examined information on 9,047US adults who did not have signs ofheart disease when they enrolled in a community-based study.
“Many physicians probably recognize that patients with cardiovascular disease are at risk of kidney disease progression, but to my knowledge, this is the first study quantifying the contribution of different cardiovascular diseases to the development of kidney failure, said Dr. Matsushita.
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.
I have to admit that I have been seeing items and ads about CoQ10 for years and never paid it much attention. I stumbled across this rundown in Medical News Today and was amazed at its functionality. I thought it would interest you.
CoQ10 is an antioxidant that exists in almost every cell of the human body. CoQ10 deficiency is associated with various medical conditions, such as heart disease, cancer, and Alzheimer’s disease.
Although the body naturally produces CoQ10, some people may benefit from taking supplements. Overall, CoQ10 supplements appear relatively safe and cause few side effects. Supplements are not regulated by the Food and Drug Administration (FDA) for purity or verified for labeling accuracy, so purchase only those products that have been tested by an independent lab.
People who are interested in trying CoQ10 supplements may want to consult a healthcare professional first. Experts do not recommend CoQ10 for people taking blood-thinning medications, insulin, or certain chemotherapy drugs.Continue reading →
Ear less; move more; live longer. Works like a charm
Generally, exercise is considered good for you. However, physicians and medical doctors previously prescribed bed rest to people with heart failure, fearing exercise could potentially lead to additional health problems.
Now, research from the University of Missouri has found exercise can improve the health of blood vessels in the heart for people with heart failure. The finding is based on a study looking at swine, which have very similar blood vessels and heart muscles – both structurally and functionally – as humans.Continue reading →
Regular exercise is highly beneficial for all patients with cardiovascular disease regardless of age, report investigators in the Canadian Journal of Cardiology, published by Elsevier. Their results showed that the patients who benefited most from cardiac rehabilitation were those who started out with the greatest physical impairment. Continue reading →
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?
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.
