As regular readers know I pretty much ride my bike every day here in Chicago. I say ‘pretty much’ because several years ago, my doctor told me that I shouldn’t be doing my big rides in high temperatures. I said that I felt I was in great shape and my body could handle it. She answered that she said the same thing to her 40-year-old patients. Extreme heat puts the body under special stress and it is not wise to actively exercise in those conditions.
Here I am riding with my dog in the annual Bike the Drive ride in Chicago down Lake Shore Drive. As a Memorial Day ride, the temps rarely hit high extremes.
Now, it seems that now only high temp extremes, but also large intra-day changes can be damaging, according to a study being presented at the American College of Cardiology’s 67th Annual Scientific Session. It states that large day-to-day swings in temperature were associated with significantly more heart attacks in a study being presented at the American College of Cardiology’s 67th Annual Scientific Session.
Regarding extreme weather events, Hedvig Andersson, MD, a cardiology researcher at the University of Michigan and the study’s lead author, said, “Our study suggests that such fluctuations in outdoor temperature could potentially lead to an increased number of heart attacks and affect global cardiac health in the future.”
There is a large body of evidence showing that outdoor temperature affects the rate of heart attacks, with cold weather bringing the highest risk, but most previous studies have focused on overall daily temperatures. This new study is among the first to examine associations with sudden temperature changes. Continue reading

I am fortunate in that I like nuts in all manner and form. Always have. So, nuts are an integral part of my daily diet.
Many people think of nuts as just another junk food snack. In reality, nuts are excellent sources of healthy fat, protein, and other healthful nutrients.
One surprising finding from nutrition research is that people who regularly eat nuts are less likely to have heart attacks or die from heart disease than those who rarely eat them. Several of the largest cohort studies, including the Adventist Study, the Iowa Women’s Health Study, the Nurses’ Health Study, and the Physicians’ Health Study have shown a consistent 30 percent to 50 percent lower risk of myocardial infarction, sudden cardiac death, or cardiovascular disease associated with eating nuts several times a week. In fact, the FDA now allows some nuts and foods made with them to carry this claim: “Eating a diet that includes one ounce of nuts daily can reduce your risk of heart disease.” Continue reading
I am now in my seventh year of writing this blog on Food, Exercise and Living Longer. Nearly a million people have read posts in that period and the readership grows on a daily basis. So I was very surprised to learn that with all the increased sensitivity to nutrition, yoga, cross fit, exercise of every stripe, it seems, heart attack patients are getting younger and more obese.
Despite increased understanding of heart disease risk factors and the need for preventive lifestyle changes, patients suffering the most severe type of heart attack have become younger, more obese and more likely to have preventable risk factors such as smoking, high blood pressure, diabetes and chronic obstructive pulmonary disease, according to a study scheduled for presentation at the American College of Cardiology’s 65th Annual Scientific Session.
The new study analyzed heart disease risk factors among more than 3,900 patients who were treated for ST-elevation myocardial infarction, or STEMI–the most severe and deadly type of heart attack–at Cleveland Clinic between 1995 and 2014.
“On the whole, the medical community has done an outstanding job of improving treatments for heart disease, but this study shows that we have to do better on the prevention side,” said Samir Kapadia, M.D., professor of medicine and section head for interventional cardiology at Cleveland Clinic and the study’s primary investigator. “When people come for routine checkups, it is critical to stress the importance of reducing risk factors through weight reduction, eating a healthy diet and being physically active.”(My emphasis) Continue reading

Are you concerned about your heart health?
Here are some tips to help you look after your heart.
- Quit smoking now. Twelve months after quitting, your increased risk of dying from heart disease will be half that of a continuing smoker.
- Improve your diet. Include wholegrain cereals, legumes, fruits, vegetables, seeds and nuts in your diet and lower your risk of heart disease.
- Exercise regularly. Walk briskly for 30 minutes a day and reduce your risk of heart attack by one third.
- Maintain your friendships. People with supportive friendship networks are at less risk of heart disease.
- Eat more fish. Oily fish like tuna, sardines or salmon are rich in omega-3 fatty acids and will boost your good cholesterol.
- Switch your chocolate choice. Switch from milk chocolate to dark chocolate. When eaten in moderation, dark chocolate is good for your heart.
- Limit your alcohol. It is recommended you limit yourself…

Commenting on the results, Dr Murray, who worked on all three studies, said: “There have been a great many findings demonstrating a role for nitrate in reducing blood pressure and regulating the body’s metabolism. These studies represent three further ways in which simple changes in the diet can modify people’s risk of type 2 diabetes and obesity as well as potentially alleviating symptoms of existing cardiovascular conditions to achieve an overall healthier life.”

Green veg contains nitrate could improve heart’s efficiency, blood supply to organs and reduce risk of diabetes and obesity
In three independent studies, scientists from the Universities of Southampton and Cambridge have identified how a simple chemical called nitrate, found in leafy green vegetables, can help thin blood ensuring oxygen can be delivered to all corners of the body efficiently. Reducing the thickness of blood may also decrease instances of dangerous clots forming and reduce the risk of stroke and heart attacks.
The same researchers, part-funded by the British Heart Foundation (BHF), also found nitrate can help the diseased heart to function more efficiently, help produce more of a compound that widens and opens blood vessels and help change bad white fat cells into good brown, fat-burning cells, which could combat obesity and reduce risk of type 2 diabetes.
In the first (1) study published this week in the Journal…

It makes sense for people at high risk of heart problems to take aspirin, he concluded.
“For all those people, they should take aspirin for the long haul, because the benefits outweigh the risk,” Gaziano said. “But if you’re very low risk, the benefits of aspirin likely don’t outweigh the risk” of increased bleeding.

Daily low-dose aspirin therapy may not have significant heart-health benefits for older people, new research suggests.
The study, which involved more than 14,000 Japanese people aged 60 to 85, found no major difference in heart-related deaths or non-fatal heart attacks and strokes between people who took aspirin and those who didn’t.
“It indicates that primary prevention with daily low-dose aspirin does not reduce the combined risk in this population,” said study co-author Dr. Kazuyuki Shimada, of the University of Shin-Oyama City Hospital in Tochigi, Japan.
Despite this study’s findings, people should talk with their doctor before they stop taking aspirin to prevent heart attacks and strokes, said Dr. Michael Gaziano, chief of the division of aging at Brigham and Women’s Hospital in Boston and a professor at Harvard Medical School.
“Patients need to discuss this with their doctor, because I think it’s difficult to do that calculation of benefit and…

“We estimate that individuals with significant plaque buildup in the arteries of the heart are much more likely to prevent a heart attack with aspirin use than to suffer a significant bleed” explains Miedema. “On the opposite end of the spectrum, if you don’t have any calcified plaque, our estimations indicate that use of aspirin would result in more harm than good, even if you have risk factors for heart disease such as high cholesterol or a family history of the disease.”

Cardiac Screening Test May Help Determine Who Should Take Aspirin to Prevent Heart Attack
A study involving the Minneapolis Heart Institute Foundation shows that a simple test to measure plaque in the arteries of the heart may help doctors better determine who will and will not benefit from use of aspirin therapy to prevent heart disease.
For over 30 years, aspirin has been known to prevent heart attacks and strokes, but who exactly should take a daily aspirin remains unclear. New research published today in Circulation: Cardiovascular Quality and Outcomes shows that your coronary artery calcium (CAC) score, a measurement of plaque in the arteries that feed the heart, may help determine whether or not you are a good candidate for aspirin.
“Many heart attacks and strokes occur in individuals who do not appear to be at high risk,” states lead author, Michael D Miedema, MD, MPH. “Individuals with known…

How much fibre people ate before they had a heart attack did not affect how long they lived after a heart attack. But people who increased the amount of fibre they ate after a heart attack were less likely to die during the study than people who didn’t increase how much fibre they ate.

After having a heart attack, people who eat foods containing fibre, in particular cereal fibre, may live for longer than people who eat less fibre.
What do we know already?
A heart attack happens when the heart doesn’t get enough oxygen and part of it dies. This usually happens when one of the vessels that take blood and oxygen to the heart is suddenly blocked.
Heart attacks are medical emergencies, which need to be treated in hospital straight away. After a heart attack, making lifestyle changes can help some people to recover and live for longer.
A previous study of people who’d had a heart attack looked at whether those who ate more foods with a lot of fibre (such as beans and lentils, wholegrain cereals, oats, fruits and vegetables) lived for longer than people who ate less fibre. It suggested fibre wasn’t linked to how long people lived after…

“Of all the lifestyle factors, we found that smoking avoidance played the largest role in reducing the risk of coronary heart disease and mortality,” says Roger Blumenthal, M.D., a cardiologist and professor of medicine at the Johns Hopkins University School of Medicine, director of the Ciccarone Center and senior author of the study. “In fact, smokers who adopted two or more of the healthy behaviors still had lower survival rates after 7.6 years than did nonsmokers who were sedentary and obese.”

A large, multi-center study led by Johns Hopkins researchers has found a significant link between lifestyle factors and heart health, adding even more evidence in support of regular exercise, eating a Mediterranean-style diet, keeping a normal weight and, most importantly, not smoking.
The researchers found that adopting those four lifestyle behaviors protected against coronary heart disease as well as the early buildup of calcium deposits in heart arteries, and reduced the chance of death from all causes by 80 percent over an eight-year period. Results of the study, “Low-Risk Lifestyle, Coronary Calcium, Cardiovascular Events, and Mortality: Results from the Multi-Ethnic Study of Atherosclerosis,” are described in an online article by the American Journal of Epidemiology.
“To our knowledge, this is the first study to find a protective association between low-risk lifestyle factors and early signs of vascular disease, coronary heart disease and death, in a single longitudinal evaluation,” says…

Another good reason to cut down/out the red meat.

The risk of hospitalisation or death from heart disease is 32% lower in vegetarians than people who eat meat and fish, according to a new study from the University of Oxford.
Heart disease is the single largest cause of death in developed countries, and is responsible for 65,000 deaths each year in the UK alone. The new findings, published in the American Journal of Clinical Nutrition, suggest that a vegetarian diet could significantly reduce people’s risk of heart disease.
‘Most of the difference in risk is probably caused by effects on cholesterol and blood pressure, and shows the important role of diet in the prevention of heart disease,’ explains Dr Francesca Crowe, lead author of the study at the Cancer Epidemiology Unit, University of Oxford.
This is the largest study ever conducted in the UK comparing rates of heart disease between vegetarians and non-vegetarians.
The analysis looked at almost 45,000…
