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.
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 →
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 →
As a dog owner, I absolutely have a bias on this subject. Also, I want to credit Learning from Dogs, Paul Handover’s fine blog for first publishing this as a part of one of his posts.
Dog owners have better results after a major health event.
The studies found that, overall, dog owners tend to live longer than non-owners. And they often recover better from major health events such as heart attack or stroke, especially if they live alone.
This is my dog, Gabi, sitting in her basket on one of our rides.
As dog lovers have long suspected, owning a canine companion can be good for you. In fact, two recent studies and analyses published in Circulation: Cardiovascular Quality and Outcomes, a scientific journal of the American Heart Association, suggest your four-legged friend may help you do better after a heart attack or stroke and may help you live a longer, healthier life. And that’s great news for dog parents!
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.
Researchers reviewed data from CONSTANCES, a French population-based study group started in 2012, for information on age (18-69), sex, smoking and work hours derived from questionnaires from 143,592 participants. Cardiovascular risk factors and previous stroke occurrences were noted from separate medical interviews. Continue reading →
Living past 100 is no walk in the park, although including one can prove very helpful. The American Heart Association has created this list with the goal of improved health by educating the public on how best to live longer and healthier.
These measures have one unique thing in common: any person can make these changes, the steps are not expensive to take and even modest improvements to your health will make a big difference. Start with one or two. This simple, seven step list has been developed to deliver on the hope we all have–to live a long, productive healthy life.
Manage Blood Pressure
High blood pressure is a major risk factor for heart disease and stroke. When your blood pressure stays within healthy ranges, you reduce the strain on your heart, arteries, and kidneys which keeps you healthier longer. Learn how to manage your blood pressure. Continue reading →
So often the answer to any health question comes back to exercise – physical activity. Eat less; move more; live longer remains the mantra of this blog. From the following, the American Heart Association (AHA) seems to agree.
Improving physical function among older adults with heart disease helps heart health and even the oldest have a better quality of life and greater independence.
Healthcare providers should emphasize cardiac rehabilitation when appropriate and provide individualized guidance on increasing daily physical activities for older patients with heart disease.
Improving physical activity among older adults with heart disease benefits their heart health, independence and quality of life, according to a new American Heart Association scientific statement published in the American Heart Association journal Circulation.
Physical activity helps reduce heart disease symptoms for patients with heart failure, heart attacks and stroke, and it also helps to improve the age-related erosions of strength, balance, and reduces frailty that particularly affect older heart patients. It is important part of care for the growing population of older adults with heart disease.
“Many healthcare providers are focused only on the medical management of diseases, such as heart failure, heart attacks, valvular heart disease and strokes, without directly focusing on helping patients maximize their physical function,” said Daniel E. Forman, M.D., the geriatric cardiologist who chaired the American Heart Association panel that drafted the new statement. Continue reading →
Sugars in your diet can be naturally occurring or added. Naturally occurring sugars are found naturally in foods such as fruit (fructose) and milk (lactose). Added sugars are sugars and syrups put in foods during preparation or processing, or added at the table.
Foods Containing Added Sugars
The major sources of added sugars are regular soft drinks, sugars, candy, cakes, cookies, pies and fruit drinks (fruitades and fruit punch); dairy desserts and milk products (ice cream, sweetened yogurt and sweetened milk); and other grains (cinnamon toast and honey-nut waffles).
According to the American Heart Association (AHA): • Poor sleep – even if you don’t have sleep apnea – may be linked to higher risks of developing an irregular heartbeat. • In addition, getting less rapid-eye movement (REM) sleep may also be linked to higher atrial fibrillation risks.
Disruptions in sleep may be raising your risks of an irregular heartbeat, known as atrial fibrillation (AF), according to preliminary research presented at the American Heart Association’s Scientific Sessions 2016. Continue reading →
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.

Everybody alive knows that medical bills go up every year. But, what to do about it? The American Heart Association has a healthy suggestion – exercise.
Getting recommended levels of exercise weekly may help keep down annual medical costs both for people with and without cardiovascular disease, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.
Although it’s well known that regular moderate exercise reduces risk of heart disease, stroke, and chronic conditions such as diabetes and high blood pressure, “our findings also emphasize the favorable impact on how much you pay for healthcare,” said Khurram Nasir, M.D., M.P.H., senior author of the study and director of the Center for Healthcare Advancement & Outcomes and the High Risk Cardiovascular Disease Clinic at Baptist Health South Florida in Coral Gables.

In December 2013 I posted for the first time on the dangers of sitting too long. “I must confess I was amazed to learn that simply sitting for long periods could be as the headline says, “Hazardous to Your Health and Longevity.” So, it’s not enough to exercise regularly, you also need to make sure that you don’t sit immobile for long periods….” That was the first sentence in the post Too much sitting can be hazardous to your health and longevity.
Now comes the American Heart Association saying, “Being sedentary is not just a lack of exercise, it is a potentially independent risk factor for heart disease and stroke.
“Regardless of how much physical activity someone gets, prolonged sedentary time could negatively impact the health of your heart and blood vessels,” said Deborah Rohm Young, Ph.D., director of behavioral research at Kaiser Permanente Southern California in Pasadena and chair of the new scientific statement published in the American Heart Association journal Circulation.
“According to the statement, sedentary behavior may be associated with an increased risk of developing diabetes, cardiovascular disease, impaired insulin sensitivity (linked to diabetes) and an overall higher risk of death from any cause. (my emphasis) Continue reading →
Regular readers know that I am a senior citizen who exercises daily and eats intelligent amounts and kinds of food to remain healthy. I take only a single drug for my prostate. Most of the seniors I know take a number of drugs, prescription and over the counter, to keep them going.
• For the first time, the American Heart Association has issued a statement cautioning that drugs used to treat a variety of conditions can cause or worsen heart failure. • Patients should show each of their healthcare providers a complete list of their medications, including over-the-counter drugs and natural supplements. • Patients with heart failure should consult with a health professional before starting or stopping any medication.
Commonly used medications and nutritional supplements may cause or worsen heart failure, according to the first scientific statement from the American Heart Association to provide guidance on avoiding drug-drug or drug-condition interactions for people with heart failure.
The statement provides comprehensive information about specific drugs and “natural” remedies that may have serious unintended consequences for heart failure patients.
Heart failure patients have, on average five or more separate medical conditions and take seven or more prescription medications daily, often prescribed by different healthcare providers.
“Since many of the drugs heart failure patients are taking are prescribed for conditions such as cancer, neurological conditions, or infections, it is crucial but difficult for healthcare providers to reconcile whether a medication is interacting with heart failure drugs or making heart failure worse,” said Robert L. Page II, Pharm.D., M.S.P.H., chair of the writing committee for the new scientific statement published in the American Heart Association journal Circulation. (my emphasis) Continue reading →
The American Heart Association strongly refutes the findings of a May 20, 2016 article in The Lancet by Mente, et al, that suggest low sodium intake is related to a higher risk of heart disease and death. On the contrary, the link between excessive sodium and high blood pressure – as well as higher risks of heart disease, stroke, heart failure and kidney disease – is indisputable. Lowering sodium is more important than ever.
Consider the following: • One-third of Americans have high blood pressure • 90% of all American adults will develop hypertension over their lifetime • Heart disease and stroke are the world’s two leading causes of death(my emphasis)
“The findings in this study are not valid, and you shouldn’t use it to inform yourself about how you’re going to eat,” said Mark A. Creager, M.D., president of the American Heart Association and director of the Heart and Vascular Center at Dartmouth-Hitchcock Medical Center. “The large body of science clearly shows how excessive amounts of sodium in the American diet can cause high blood pressure, which can lead to heart disease, stroke, and even death.” Continue reading →
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.
Researchers studied a racially diverse group of older adults and found that having more ideal cardiovascular health factors was associated with better brain processing speed at the study’s start and less cognitive decline approximately six years later. Continue reading →
