Cold Weather Increases Heart Failure Risk, Says New Study

Dropping temperatures and changes in atmospheric pressure can lead to an increase in the risk of heart failure for elderly people, according to a large-scale study – and more care needs to be taken to counter the effects.

Previous research has shown that changes in the weather can affect the health of vulnerable people – for example, heat waves and cold spells have been shown to increase disease and even lead to death in people from low-income neighborhoods. The new study, led by researchers at Université Laval and Université de Sherbrooke in Quebec, Canada, reveals the impact of changes in temperature and air pressure on heart failure patients.

“We know that doctors rarely take the weather forecast into account when treating or making recommendations to heart failure patients,” said Prof. Pierre Gosselin, lead author of the study from Universitié Laval in Canada. “So with the extreme differences in temperature due to climate change, we wanted to show how the weather is becoming a more relevant factor. Our study shows that exposure to cold or high-pressure weather could trigger events leading to hospitalization or death in heart failure patients.”

Treating heart failure patients is expensive: according to the Institut Canadien d’Information sur la Santé, people over 65 accounted for 78 percent of patients with the most expensive hospitalization costs per diagnosis between 2011 and 2012 in Canada. Of these, the cost of heart failure ranked third and was estimated at CAN$276 million.

In the new study, the team assessed 112,793 people aged 65 years and older that had been diagnosed with heart failure in Quebec between 2001 and 2011. Patients with heart failure were identified in the Quebec Integrated Chronic Disease Surveillance System (QICDSS) database using the International Classification of Diseases (ICD).

The participants were followed for an average of 635 days. During this time, the researchers measured the mean temperature, relative humidity, atmospheric pressure and air pollutants in the surrounding environment and studied the data to see if there was an association.

The results showed a higher risk of hospitalization or death in the winter period of the year (October to April) compared to the summer period (May to September).

The researchers noticed that the risk to experience hospitalization or death of heart failure cause was increased of 0.7 percent for every 1°C decrease in the mean temperature of the previous seven days. They also found that the risk of heart failure incident increased by 4.5 percent for each increase of 1 kPa in atmospheric pressure.

In other words, a drop of 10°C in the average temperature over seven days, which is common in several countries because of seasonal variations, is associated with an increased risk in being hospitalized or dying of heart failure of about 7 percent in people aged over 65 diagnosed with the disease.

During the follow-up period, 21,157 heart failure events occurred, representing 18.7 percent of the people studied. In total, 18,309 people were hospitalized and 4,297 died. In some cases, hospitalization and death occurred the same day. The researchers calculated this to 0.03 percent of patients experiencing an incident per day, which extends to about 1500 hospitalizations or deaths over a 10-year period, or 150 events per year.

Prof. Gosselin and the team suggest that elderly with heart failure should be given support and access to preventive measures, especially since managing heart failure is expensive for society. He commented:

“Our study suggests that exposure to cold or high-pressure weather could trigger events leading to hospitalization or death in heart failure patients. This means that they should avoid exposure to fog and low cloud weather in winter as they often accompany high pressure systems.”

Study Shows Why It’s Massively Important to Have a Good Attitude

Positive thinking may reduce your risk of this deadly disease

Could a grin on your face be your ticker’s saving grace? 

In a new study at Penn State University, scientists looked at more than 1,000 people with coronary heart disease over a 5-year period. Patients who reported having higher levels of positive emotions like determination, excitement, and enthusiasm were more likely to exercise, sleep better, and avoid smoking.

Not surprisingly, those three measures can all reduce your risk of heart disease, according to previous research.

Although the people in this study already had heart problems—and their positive attitudes helped them maintain better health behaviors—other research pegs happiness as a proven preventative tool. A study in the American Journal of Cardiology found that positive well-being was associated with nearly a one-third reduction of coronary artery disease.

The scientists aren’t exactly sure why people with better attitudes are more likely to engage in healthy behaviors, but they have a few theories.

Happier people may be more motivated to carry out and stick to health routines, adjust health-related goals, or cope with the setbacks of having ticker trouble, says study author Nancy Sin, Ph.D.

The most encouraging part of the findings is that the people who had great outlooks weren’t necessarily that way from the start. Patients who increased their positive emotions as the study went on were more likely to keep up healthy behaviors.

Stress and depression tend to hog all the headlines when it comes to factors that influence our health. So we tend to overlook the huge impact that positive thinking can have, says Sin.

But as the study shows, you can always turn your attitude around. “Start with small changes in your life,” says Sin.

Managing Your Emotions Can Save Your Heart

We often think of the heart and brain as being completely separate from each other. After all, your heart and brain are located in different regions of your body, and cardiology and neurology are separate disciplines. Yet these organs are intimately connected, and when your emotions adversely affect your brain, your heart is affected as well.

The negative impact of emotions when your heart is already vulnerable

There are two kinds of stress that impact your brain. Helpful stress (also known as eustress) can assist you with getting things done by helping you focus your attention. Unhelpful stress (distress), on the other hand, can be so severe that it can lead to fatigue and heart disease.

If you have coronary artery disease (CAD), your heart may be deprived of oxygen. This deprivation, called myocardial ischemia, can occur in as many as 30% to 50% of all patients with CAD. It can be further exacerbated by emotional stress. In fact, if you have any type of heart disease, any strong emotion such as anger may also cause severe and fatal irregular heart rhythms. Expressions like “died from fright” and “worried to death” are not just hyperbole — they are physiologic possibilities. Furthermore, when patients with newly diagnosed heart disease become depressed, that depression increases the risk that a harmful heart-related event will occur within that year.

The negative impact of emotions when you have no heart disease

Of course, stress can have a big effect on your heart even if you don’t have heart disease. Here’s just one example: In 1997, cardiologist Lauri Toivonen and colleagues conducted a study of EKG changes in healthy physicians before and during the first 30 seconds of an emergency call. They saw changes that indicated oxygen deprivation and abnormal heart rhythms.

More recent studies have also observed these changes in the setting of with stress, anxiety, and depression — all of which are, of course, brain-based conditions. Even in people with no prior heart disease, major depression doubles the risk of dying from heart-related causes.

Cardiac psychology: Tending to your emotions for your heart’s sake

It is important to control your worry and stress, not just because you will worry less and feel better, but because less worry means less stress for your heart. This applies to the entire range of stressors, from a small episode of acute panic to a larger context such as living through a natural disaster. For all the reasons outlined above, a new emotion-based approach to heart health, called cardiac psychology, is receiving increasing interest.

You really can change your brain and get a healthier heart in the process. Here are some ways to get started:

  • Seek professional help. Don’t ignore stress, anxiety, depression, excessive worry, or bouts of anger that overwhelm your life. Seek professional help. If you meet criteria for a diagnosis, treatment can help reduce symptoms, thereby protecting your brain and your heart.
  • Available treatments in cardiac psychology. Aside from more traditional psychiatric treatment and exercise, psycho-educational programs, educational training, stress management, biofeedback, counseling sessions, and relaxation techniques should all be considered before or after a heart-related event. Newer treatments such as acceptance and commitment therapy and expressive writing can also be helpful.
  • Exercise. Physical exercise can help you have a healthier heart and brain — in the right doses. For example, many recent studies have demonstrated that aerobic exercise can help you be more mentally nimble by helping you think faster and more flexibly. Even frail older adults have improved their thinking and overall psychological well-being from exercising for one hour, three times a week. And people in rehabilitation after being diagnosed with heart failure report clearer thinking when their fitness levels improve.As clinical research scientist Michelle Ploughman commented, “exercise is brain food.” Various types of aerobic exercise, including jogging, swimming, cycling, walking, gardening, and dancing, have all been proven to reduce anxiety and depression and to improve self-esteem. This is thought to be due to an increase in blood circulation in the brain, and the fact that exercise can improve the brain’s ability to react to stress.

 

A starting point for better brain — and heart — health

If you struggle with stress, anger, anxiety, worry, depression, or problems with self-esteem, talk to your primary care physician — or a cardiologist, if you have one. A consultation with a psychiatrist may be very helpful. Together, you can explore which of these potential therapies might best protect your psychological state, your brain, and your heart.

Laugh, Cuddle to Unclog Arteries? Why One Cardiologist Swears By Happy Healers

Michael Miller, MD, has seen firsthand how the power of positive emotions can help our hearts get and stay healthy.

By Michael Miller, MD with Catherine Knepper from Heal Your Heart

Also in Reader’s Digest Magazine March 2015

One of my favorite moments as a physician occurs when, with a very somber look, I inform patients that there’s one thing they absolutely must do in order to make a successful recovery after a cardiac event: Go home and laugh until they cry.

You see, we now know that there’s far more to maintaining heart health and reversing heart disease than diet, exercise, and cholesterol levels. The latest research indicates that stress, and an inability to deal with it, is a direct contributor to heart disease. For example, a study involving nearly 250,000 people found that anxiety was associated with a 26 percent increase in coronary heart disease over an 11-year period.

Anger and hostility rank at the top of the list of heart-harmful emotions. Harvard Medical School researchers recently found that 40 percent of patients who suffered a heart attack reported significant anger within the previous year, and roughly 8 percent of that group reported that they felt rage within two hours of heart attack symptoms.

But while studies reveal a great deal about the harm that negative emotions deliver to the heart, they also clearly demonstrate the amazing healing power of positive emotions. In my 25 years as a cardiologist performing clinical trials and treating patients, I’ve seen firsthand how we can harness optimism, confidence, laughter, social connections, and relaxation to help our hearts get and stay healthy.

laughing

Laugh Hysterically

Deep belly laughter triggers the release of endorphins, which activate receptors in our blood vessels’ linings that signal the production of nitric oxide. This powerful chemical causes blood vessel dilation, increases blood flow, reduces vascular inflammation and buildup of cholesterol plaque, and decreases platelet stickiness, which lowers the risk of blood clots.

In an early study, my team saw that people with heart disease were 40 percent less likely to use humor in an uncomfortable situation, such as having a waiter spill a drink on them, than people with healthy hearts. In another study, when we asked people to watch a clip from Saving Private Ryan or There’s Something About Mary, we found that participants’ blood vessels were narrowing by up to 50 percent during the stress-inducing clip, while vessel dilation in people who watched a funny clip increased 22 percent. After just 15 minutes of laughing, volunteers got the same vascular benefit as they would from spending 15 to 30 minutes at the gym or taking a daily statin.

Cue the Music

Medical science is now proving what people have known for hundreds of years: that music is deeply healing. In one study, researchers found that listening to music 25 minutes daily for four weeks resulted in a 12 mm Hg reduction in systolic blood pressure (the top number) and a 5 mm Hg decrease in diastolic blood pressure (the bottom number). Results like these are equivalent to the benefit of taking a strong blood pressure medication.

The calming effect of music is so powerful that listening to relaxing music before cardiac surgery was more effective at reducing stress than a sedative medication. And a group who listened to music after surgery fared better than patients who received the sedative. One theory is that music acts directly on the body’s autonomic nervous system, which is responsible for heart rate and blood pressure.

Cuddle Up

During childhood visits to the doctor, I remember feeling that everything would be fine when my pediatrician would place his hand on my upper shoulder as he listened to my lungs. Early in my training, I did the same thing to my patients. Several studies support the idea that interpersonal touch has important heart-health benefits. In one study, women who received frequent hugs from their partner showed reduced heart rates and blood pressure as well as higher levels of the powerful neurotransmitter oxytocin, which leads to blood vessel dilation.

10 Tips for a Healthier Heart

Are you concerned about your heart health?

e9244-healthy_heart-290x300

Here are some tips to help you look after your heart.

  1. Quit smoking now. Twelve months after quitting, your increased risk of dying from heart disease will be half that of a continuing smoker.
  2. Improve your diet. Include wholegrain cereals, legumes, fruits, vegetables, seeds and nuts in your diet and lower your risk of heart disease.
  3. Exercise regularly. Walk briskly for 30 minutes a day and reduce your risk of heart attack by one third.
  4. Maintain your friendships. People with supportive friendship networks are at less risk of heart disease.
  5. Eat more fish. Oily fish like tuna, sardines or salmon are rich in omega-3 fatty acids and will boost your good cholesterol.
  6. Switch your chocolate choice. Switch from milk chocolate to dark chocolate. When eaten in moderation, dark chocolate is good for your heart.
  7. Limit your alcohol. It is recommended you limit yourself to no more than two standard glasses of alcohol a day if you are a man, or one glass a day if you are a woman.
  8. Avoid salty and high sodium foods. Don’t add salt when preparing or eating your meals.
  9. Have a diabetes test. Uncontrolled diabetes can damage your artery walls and contribute to heart disease.
  10. Make fitness fun. Choose activities that combine exercise and socialising like pilates, water aerobics, dancing, cycling or yoga.

Don’t Fall Victim to the Holiday Heart Attack

Heart and Stroke Foundation    December 4, 2013

It’s a sobering reality amid the holiday cheer: More people die from a heart attack or stroke in the winter months than during warmer weather, with mortality rates averaging 10 per cent higher. For older Canadians, the danger is even greater. Plus, cold weather is associated with increased blood pressure, which in turn raises your risk of heart disease and stroke.

 Maintaining healthy habits will help reduce your risk through the festive season

You can reduce your risk of heart disease and stroke by making healthy choices any time of the year – eating well, being physically active, managing your stress, limiting alcohol and being smoke free. But of course that can be especially difficult this season, with its whirl of social demands, temptations – and stress.

“Maintaining healthy habits through the holidays is a challenge, but it’s so important,” says Heart and Stroke Foundation registered dietitian Carol Dombrow. “With a little planning and mindfulness, you can find a healthy balance and still enjoy the season.”

These tips will help you have a healthier holiday.

Eat for balance

Sugary, high fat and high calorie temptations are everywhere. To keep up your energy and get all the nutrients you need, limit treats and choose foods from all four food groups. Follow Canada’s Food Guide and ensure that half your plate is vegetables, one quarter meat or alternatives such as beans, lentils or tofu, and one quarter grains such as rice or pasta. Add in a glass of milk or some yogurt and fruit.

Snack before parties

Eating a protein-rich snack before a holiday party will help you stay fuller and say no to salty and sugary bites.

Keep indulgences small

With all the sweet treats offered over the holidays, you can still enjoy your favorites by keeping portions small. Or try these better-for-you swaps to satisfy your sweet tooth.  

Stay active

Regular physical activity boosts feel-good endorphins that help you manage stress. Winter sports like skating, tobogganing and skiing are a great way to make the most of the season. Prefer to stay warm? Consider indoor swimming or melt stress away with a yoga class.

Hit the snooze button

Shortchanging yourself on sleep can you leave you feeling cranky, raise blood pressure levels and even lead to overeating. Stay refreshed during the holidays by logging eight hours a night.

Shop smart

Head off stress by making a plan before you hit the stores. It will help you limit spending and avoid unnecessary backtracking. Skip the wrapping chaos by dropping off presents at a gift-wrapping station that donates proceeds to charity.

Sip smart

Whether you’re drinking a glass of wine or a cup of frothy eggnog, it’s easy to over-consume alcohol during the holidays. “Heavy drinking is a risk factor for high blood pressure and stroke,” says Dombrow. For men, limit alcohol intake to three drinks per day, to a weekly maximum of 15. Women should limit themselves to two drinks per day, to a weekly maximum of 10. One drink equals 12 ounces of beer, five ounces of wine, or 1.5 ounces of spirits. And remember that alcohol is also high in calories. 

Ask for help 

If you feel lonely or isolated during the holidays, seek out support from your friends, community, or place of worship. Take time to recognize and share your feelings with others. 

Keep it real

Without a big budget movie crew, it’s almost impossible to create a picture-perfect holiday dinner. Give yourself a break. Perfect may be unreachable but enjoyable is well within your grasp if you set realistic goals for the season.
