The Third Leading Danger to Your Heart

Healthy Living, Heart and Vascular, Lifestyle, Uncategorized ccmh, comanche county memorial hospital, health care, heart, heart and vascular, hospital, lawton, lifestyle, Venous Thromboembolism

If asked what the leading vascular diagnosis was, most people would know heart attack and stroke. However, the third leading cause of danger to your heart is no small matter either. In fact, each year, between 300,000 and 600,000 Americans receive a diagnosis of venous thromboembolism (VTE). 1

VTE has two types: pulmonary embolism (PE) and deep vein thrombosis (DVT). Deep vein thrombosis is a clot deep in the vein. When a DVT clot breaks away from a vein wall, travels to the lungs, and then blocks some or all of the blood supply, a pulmonary embolism occurs.

Pulmonary embolism occurs when the DVT clot breaks away, travels to the lungs and blocks part or all of the blood supply.

Symptoms of venous thromboembolism

Symptoms of deep vein thrombosis often include reddish or bluish skin discoloration, a leg that is warm to touch, leg tenderness or pain and swelling in one leg.

Pulmonary embolism symptoms are sudden shortness of breath, stabbing chest pain that gets worse with each breath, rapid heart rate, and an unexplained cough sometimes accompanied by bloody mucus.

The cause of venous thromboembolism

Venous thromboembolism may be caused by cancer, immobilization surgery, or hospitalization.

Deep vein thrombosis occurs when the flow of blood changes or slows. For women, using hormones like oral contraceptives or estrogen for menopause symptoms can also play a role. Pregnancy may also be a cause of VT.

Who is at risk for venous thromboembolism

Those at risk for clotting and developing VT include:

those who are overweight or obese

the elderly

patients of autoimmune disorders

patients that overproduce blood cells and have thickened blood

cancer patients

How to prevent venous thromboembolism

You can lower your risk of VT by staying active and losing weight if needed. Discuss concerns you may have with your doctor and take “blood thinners” if recommended. Follow self-care techniques prescribed by your doctor if you have conditions such as diabetes or heart failure. Also, consider the risk of taking certain medications such as hormones.

Sugar Substitutes and Stroke Risk

CCMH

Healthy Living, Heart and Vascular, Lifestyle ccmh, comanche, comanche county memorial hospital, health care, heart, heart and vascular, lawton, lifestyle, oklahoma

To decrease the amount of sugar in your diet, you may be tempted to reach for diet soft drinks or juices sweetened with sugar substitutes. Sugar substitutes are a confusing topic for many. For years it seemed that they received nothing but negative publicity. Recently, research reported they may not be as bad as we once thought. This leaves research relatively inconclusive at best. However, concern is once again growing.

Latest research demonstrates concern regarding artificial sweetener consumption

Although they may seem like a good alternative to sugar-filled drinks, recent studies have discovered that there may be a link between artificial sweeteners and health risks including stroke.

Over 81,000 women between the ages of 50 and 79 participated in the study. The conclusion drawn by researchers was that artificially sweetened drinks are associated with an increased risk of heart disease, stroke and even death.

Those who drank two or more diet drinks a day had a 23% increase of stroke risk compared to those who consumed less than one diet drink per week. 1

Sugar consumption alters taste

No matter if you choose real sugar, or an artificial or plant based substitute, the brain wants more sweet substances the more you consume.

Artificial sweeteners even alter our gut bacteria. Sugar, in general, also increases blood sugar and insulin levels.

All of these factors combined lead to excessive weight gain, including fat, and also inflammation.

The danger of consuming artificial sweeteners for many lies in the increase of sweet cravings it causes. Artificial sweeteners are designed to taste sweeter than real sugar. This causes your taste buds to crave and expect more sweet foods.

Decreasing sugar in diet

To determine whether or not you are consuming too much sugar, try eating some fruits such as strawberries and apples. If you notice that these fruits do not taste sweet to you, this could be an indication that you should decrease the amount of sugar in your diet.

With some small changes, you can greatly reduce sugar intake. Begin by removing any added table sugar, honey, syrup or molasses. Natural sugar substitutes such as unsweetened applesauce or spices like cinnamon and allspice are great baking substitutes. Also, cut back on your serving size when you do indulge in sugary treats and check food labels for treats with less added sugar when possible.

Making dietary changes always seems overwhelming at first. However, with practice, anything can become a natural part of your lifestyle. If you have questions about ways to consume a healthier diet, make an appointment with a CCMH provider.

The Dangers of Energy Drinks

CCMH

Healthy Living, Lifestyle caffeine, ccmh, comanche, comanche county memorial hospital, energy drinks, health care, heart, hospital, lawton, lifestyle, oklahoma, Red Bull, stroke

When life is busy, many of us are tempted to grab an energy drink to put a little extra pep in our step. However, research continues to find concerning effects after consuming these popular beverages. Consuming multiple energy drinks in a short time or consuming energy drinks in combination with other caffeinated or alcoholic beverages, can be especially harmful.

Some lawmakers are even attempting to ban the sale of energy drinks to those under the age of 18. These legislative efforts occurred following tragic events such as the death of a sixteen-year- old boy from South Carolina. Davis Cripe suffered a cardiac episode that led to his death after consuming an energy drink, coffee and Mountain Dew in less than an hour. 1

What are the harmful ingredients in energy drinks?

The main ingredients of most energy drinks are caffeine and sugar. However, many experts believe it isn’t necessarily the caffeine in energy drinks that is harmful. After all, most healthy individuals who do not typically experience adverse effects from caffeine can safely consume 4-5 cups of coffee per day without problem.

The problem lies in the amount of sugar and caffeine. Many energy drinks have as much caffeine as 3-4 cups of coffee and more than the recommended amount of sugar you should consume in one day.

There are additional herbal stimulants found in energy drinks that are not regulated by the FDA. These ingredients in combination with high sugar and caffeine content may be the cause of serious or fatal problems for some consumers. 2

What happens after drinking an energy drink?

Twenty minutes after ingesting an energy drink, you experience a sugar high. This blood sugar spike results in a quick release of the hormone insulin.

Forty minutes later, all the caffeine is absorbed. As a result, blood pressure rises, the liver dumps even more sugar into the bloodstream and pupils dilate.

Forty five minutes later, dopamine production occurs in the body. This hormone gives you a sensation of pleasure. This reaction is similar to how the body responds to heroin.

After 60 minutes, a sugar crash occurs. The caffeine slowly wears off and you can experience mood changes, lethargy, fatigue and mental fogginess.

Why are energy drinks viewed as so unsafe?

It is difficult to predict how energy drinks will affect different individuals, especially with underlying heart issues or in combination with other substances containing alcohol or caffeine.

Oftentimes, individuals do not know they have a cardiac problem until something fatal occurs. For this reason, it is better to be safe than sorry when choosing how to get some extra pep to get through the day.

Despite what we do not know with certainty, the American Academy of Pediatrics has a very clear opinion of energy drink usage in children and teens. Given the observed side effects, including irregular heartbeats and blood pressure changes, the AAP recommends that children and teens should not consume energy drinks at all. 3

How to pep up without excessive caffeine

You can successfully and healthily boost energy levels in many ways that are safer than consuming copious amounts of stimulants.

Exercise regularly and participate in activities to reduce stress.

Be mindful of your diet. Reduce sugar and increase your intake of omega-3 fatty acids found in plants, seeds, fish and nuts.

Rest! Be sure to get 7-8 hours of quality rest each night.

Through safely managing your diet and routine, it is possible to achieve greater energy levels that do not involve risky habits.

Anxiety and Heart Disease

CCMH

Heart and Vascular anxiety, ccmh, comanche county memorial hospital, health care, heart, heart and vascular, heart disease, hospital, lawton, oklahoma

Is anxiety a contributing factor to heart disease? Can it also deter recovering from heart related issues? Many doctors believe so. If you suffer from anxiety, it is important to do all you can to manage your anxiety to prevent other health problems also. However, if you suffer from heart disease, dealing with this condition may cause anxiety as well.

How anxiety affects the heart

When someone experiences anxiety, the body’s reactions may also cause extra strain on the heart. Therefore, anxiety can be especially harmful to those diagnosed with cardiac disease.

The following cardiac risk factors and heart disorders may be caused by anxiety :

Decreased heart rate variability – Heart rate variability is the variation in the time interval between heartbeats. Even if your heart beats 60 beats per minute, that does not necessarily mean it beats every single second. It is normal to have some variation in how often the beats occur. Decreased heart rate variability may increase someone’s risk of death after an acute heart attack.

Tachycardia- This is rapid heart rate. In some serious cases, it interferes with normal heart function, increasing the risk of sudden cardiac arrest.

Increased blood pressure – Chronic high blood pressure can lead to coronary disease. Coronary disease weakens the heart muscle and may also cause heart failure.

Heart attack and anxiety

Dealing with anxiety after a heart attack can be difficult. It is natural to react to this life-altering event in ways that are similar to post-traumatic stress disorder. However, it is important for patients to visit with their doctor if the anxiety does not improve over time.

Someone who has a heart attack may:

be shocked by this near-death experience and afraid to participate in activities that they once did.
struggle with reliving the event, and also avoid the activity or place where it occurred.
feel negative and uncertain about their future.
have difficulty sleeping.

Furthermore, after a heart attack, many individuals may have a difficult time completing tasks essential to their recovery and a healthy lifestyle due to their anxiety. Some of these problems may include:

not taking prescribed medications
not following prescribed exercise regimens
disconnecting from friends and family
inability to confidently resume their career and family responsibilities
not following a healthy diet

Some anxiety disorders may affect heart health

Obsessive-Compulsive disorder (OCD) – Patients with OCD manage their unreasonable thoughts and worries by performing the same actions over and over. For example, a person obsessed with perceived cardiovascular symptoms may be concerned that their anxiety disorder is really a heart problem. The symptoms do after all mimic a heart condition.

Panic disorder – Panic attacks are sometimes believed to initially be heart attacks. Sufferers will feel terror, agitation, chest pains, stomach discomfort, dizziness, shortness of breath, and also have rapid heart rates.

Post-traumatic stress disorder (PTSD) – PTSD follows a shocking or frightening incident or sudden, life-threatening event. This may include a violent crime, major accident, or heart attack. Those who suffer from PTSD often have trouble dealing with anything associated with the incident that caused their anxiety.

Panic attack or heart attack?

It can be difficult to determine if a patient is suffering from anxiety or heart problems without proper treatment. A patient that suffers from chest pain—even if under the care of a physician for anxiety— should go to the emergency room. Blood tests can indicate heart muscle enzymes present due to a heart attack.

A cardiologist that is sensitive to anxiety issues will know how to sort out panic attack symptoms from heart attack symptoms and can also refer patients as needed if anxiety is the issue.

If you are having difficulty dealing with anxiety, please make an appointment with one of our providers. They would love to help you take charge of your life again. You can find a list of them at https://www.ccmhhealth.com/providers/.

Improve Heart Health in Unique Ways

CCMH

Community Health, Healthy Living, Heart and Vascular, Lifestyle ccmh, comanche, comanche county memorial hospital, fitness, health care, healthy living, heart, heart and vascular, lifestyle, oklahoma

One of the leading causes of death is cardiovascular disease. Although we cannot change certain risk factors such as age and family history, we can help prevent cardiovascular disease and hope to live a long, healthy life. You probably know that exercise and a healthy diet can help keep our hearts strong, but there are other means to improve heart health that you may not know. Here are six unique ways you can keep your heart healthy.

Crank up the music

Several studies have shown that music can have several positive effects on our bodies including lowering stress and even blood pressure. A study at Massachusetts General Hospital also found that heart patients who were confined to bed had slower heart rates, lower blood pressure, and less distress when they listened to music for 30 minutes each day. 1 So, pull out your favorite tunes, sit back and enjoy the improved heart health!

Have a laugh

We have all heard the Old Testament proverb that “laughter is the best medicine” and have experienced positive emotional effects of having a laugh. Science is proving that there are more than just emotional benefits to laughter, however. Consequently, laughter can also helps our hearts pump stronger! As we laugh, our blood vessels enlarge in diameter. This in return increases the blood flow like when we participate in aerobic exercise.

The University of Maryland also conducted a study and discovered that when people laugh at a funny movie scene, they experience improved blood flow. 2 So, head to the movies, turn on your favorite comedian or sitcom, and enjoy some laughs!

Be kind

We know that high stress levels are not good for our hearts. When we are upset, cortisol, our stress hormone, increases and our blood pressure and inflammation rises. When we experience positive emotions though, our oxytocin levels rise, helping to improve heart health, and our cortisol levels drop. Being kind to others makes us feel better emotionally and just might improve heart health.

Consider the Mediterranean Diet

Many studies have had positive heart health conclusions when studying the Mediterranean diet. According to a 2013 study from Spain, a Mediterranean style of eating can reduce heart disease risk by as much as 30%. 3

The Mediterranean diet consists of green vegetables, nuts, avocados, fruits, beans, high-fiber grains, olives and olive oil, and an occasional side of small, wild fish such as salmon. In this diet, individuals seldom consume red meat, poultry, dairy products, eggs, sugary foods and drinks, and refined flours.

Love a Pet

Could your favorite canine or feline improve heart health? According to the American Heart Association (AHA), they can! Studies show that having a pet can relieve stress, help increase fitness levels, lower blood pressure and cholesterol levels, and increase happiness and wellbeing. 4

Studies on dog owners show that they tend to live longer, have lower risks for heart disease, better cholesterol profiles, less hypertension and are less vulnerable to stress. The reason for these positive results is not entirely clear, but it could be due to the fact that dog owners are generally more active than non-owners. Either way, owning a pet who loves you unconditionally has plentiful emotional benefits.

If you’re not in a position to own a dog, local shelters often need volunteers to play with dogs. Consider playing with a friends dog or taking up dog walking and earn some extra cash too!

Offer a Hug

Oxytocin levels rise and cortisol level drop when we give and receive hugs. In a study by the University of North Carolina, Chapel Hill, participants who hugged their partners had a slower heart rate up to 10 beats per minute than those who did not hug their partners.5

So, grab someone around you who needs a hug, and enjoy the improved heart health!

Good health is often about incorporating small changes in our routine. We hope this article encourages you to add some of these activities to your routine and improve your heart health today!

Activities To Improve Heart Health

CCMH

Healthy Living, Heart and Vascular, Lifestyle ccmh, comanche, comanche county memorial hospital, exercise, fitness, health care, heart, heart and vascular, oklahoma

February is the month we dedicate as American Heart Month. Throughout February, we would like to encourage you to participate in activities to improve the health of your heart.

The heart is so important because it contains some of the body’s most valuable muscles. These muscles and the valves of the heart keep our blood moving and sustains our lives 24/7. As with all other muscles, we can improve the functionality of the heart with exercise.

Many of us are not fond of exercise, but it is very good for our bodies. Not only does regular exercise just help you live healthier and feel better, but it also helps protect you from the #1 killer in America, heart disease, and it can even add years to your life!

How should you exercise to help the heart?

If you are someone with a medical condition including a heart condition or diabetes, make an appointment to discuss what exercise routine is best in your situation.

If you are new to exercising regularly, start slow. We stick better to routines that are not too vigorous and overwhelmingly challenging. Aim for participating in 30 minutes of exercise each day.

Remember, any movement is good for you. You may be exercising and not even really realize it. As you participate in exercise, the large muscles of your body cause your heart to beat faster which strengthens them.

Don’t participate in an aerobic activity that you do not enjoy. This increases the chances of you abandoning the routine. To impact your heart, find time for moderate aerobic activity most days of the week for a total of around 2.5 hours. If you have a busy schedule, try breaking it into a few 10 to 15 minute sessions.

How does the heart benefit from exercise?

Exercise often leads to weight loss. If you’re overweight, losing even just a few pounds may significantly impact heart health and reduce the risk of heart disease.

Exercise also reduces stress. Stress can contribute to other conditions which are factors in heart disease.

Lower blood pressure is also a positive result of exercise. 30-60 minutes of aerobic activity is recommended to help bring high blood pressure into healthy range.

Lower cholesterol is also a positive benefit of exercise.

What are some heart friendly forms of moderate exercise?

Dancing

Skiing

Yard work

Hiking

Softball

Tennis (doubles)

Swimming

Golfing without a golf cart

Bicycling

Moderate walking (around 3.5 mph)

What are some more vigorous forms of heart healthy exercise?

If you participate in all vigorous activities, aim for 75 minutes of exercise each week to benefit your heart.

Vigorous activities include:

Soccer

Basketball

Tennis (singles)

Cross-country skiing

Brisk walking (about 4.5 mph)

Jogging

Heavy yard work

Stair climbing

Hiking uphill

Bicycling over 10 mph

Jumping rope

How Do I Know If I’m Helping My Heart?

To ensure you are benefitting from aerobic activity and increasing your heart health, track your heart rate. First, determine your resting heart rate. You can do so by counting your heart beats for 10 seconds and multiply that number by six.

Normal resting heart rate for adults is from 60 to 100 beats per minute. A lower resting heart rate is usually the result of more efficient heart function and cardiovascular fitness. A well-trained athlete might have a normal resting heart rate closer to 40 beats per minute for example.

Many factors influence heart rate, and there is a wide range of normal. Nevertheless, an unusually high or low heart rate can indicate a problem. Consult your doctor if your resting heart rate is above 100 beats a minute consistently or if your resting heart rate is below 60 beats a minute and you’re not a trained athlete.

During exercise, your heart rate should increase to about 50 to 85% of your maximum heart rate based on your age. For moderate intensity exercise, your target heart rate should increase to 50 to 70% of your maximum heart rate. For vigorous exercise, your target heart rate should be 70 to 85% of your maximum heart rate.

You can determine what your maximum heart rate should be for your age by viewing this article by the American Heart Association.

When you first start exercising, aim for the lower number for your age range. As your fitness improves, you can gradually aim for the higher number. No matter your age, it’s never too late to make heart health a goal.

The Toll of Stress: Shocking Effects on the Body

CCMH

Healthy Living, Lifestyle alzheimer's, ccmh, diabetes, fertility, heart, hospital, lawton, oklahoma, stress

From money, to work issues to family problems, all of us experience stress. In fact, nearly 8 in 10 Americans report feeling significant stress daily. 1 Unless you are feeling especially overwhelmed, you probably don’t think much about it. Stress is something we should be more aware of though. Negative emotions may have many negative, physical effects on the body.

How does stress affect the body?

It may surprise you to know that a little stress can boost the immune system. Although, dealing with chronic stress lowers the immune system allowing illnesses to creep in. 2 Rarely is stress the root cause of diseases, but how it interacts with our genetics and health can accelerate the spread of disease.

Which diseases are caused by stress?

The short answer is, well, all of them! Stress can lead us to bad choices to try to cope. From overindulging in comfort foods to alcohol to smoking- stress is often the root cause of negative behaviors. Hormones increased by stress also lead to various conditions.

How does stress affect heart health?

All of the above mentioned bad coping devices, overindulging in alcohol or food and smoking, can lead to obesity and high blood pressure. These are known factors leading to heart problems including heart attack and stroke. Stress also reduces blood flow to the heart which is a cause of coronary heart disease. 3

How does stress affect the brain?

A staggering 5.5 million Americans struggle with Alzheimer’s disease everyday. It is the 6th leading cause of death in the United States. 4 Studies show that links between Alzheimer’s and increased stress hormones such as cortisol may exist. High blood pressure may also lead to Alzheimer’s. In Sweden, researchers found high levels of stress hormones in the brains of mice created bigger amounts of beta-amyloid plaques, the proteins believed to cause Alzheimer’s. 5

How does stress affect fertility?

With approximately 1 in 8 couples struggling with infertility, we can’t help but wonder what role stress plays. Research in 2014 stated that high levels of stress may reduce semen and sperm quality. 6 Another study from 2014 found that women with high levels of a alpha-amylase, a stress-related enzyme in the saliva, were 29% less likely to become pregnant. They were also twice as likely to be infertile than women with low levels of the enzyme. 7

Stress plays a role in diabetes?

Most surprising of all is that scientist now believe a link exists between stress and type 2 diabetes. A study published by JAMA found women with post traumatic stress disorder in particular had almost double the risk of developing the disease than women who had not experienced trauma. 8 A possible explanation to this could be because stress increases the production of the hormone cortisol. Cortisol may raise glucose levels.

How do I tackle stress?

To tackle stress, seek support from others and engage in exercise daily. Exercise increases the production of “feel-good” neurotransmitters in the brain known as endorphins. We also posted an article: Managing Mental Health: There’s an App for That which has several apps that contain mood boosting exercises. If you feel unable to cope with stress, are having suicidal thoughts, or using drugs or alcohol to cope, make an appointment with one of our providers today. You can find a list of them at https://www.ccmhhealth.com/providers/.

NEW Absorbable Stent Technology

CCMH

Heart and Vascular absorbable stent, cardiology, ccmh, Coronary Artery Disease, health care, heart, heart and vascular, heart disease, hospital, lawton, oklahoma

Comanche County Memorial Hospital is the first hospital in the state of Oklahoma to perform a fully dissolvable stent procedure outside of a clinical trial.

The Absorb dissolving heart stent is the first and only device of its kind – a drug eluting coronary stent that dissolves, completely and naturally, in the body over time. Absorb treats coronary artery disease like a standard metallic stent, propping the diseased vessel open to restore blood flow, but then disappears after the artery is healed, leaving no metal behind to restrict natural vessel motion.
