#HeartMonth and Healthy choices

See what’s on Netflix or go for a run? We’re more than half-way through #HeartMonth and I’m still picking the next episode of Netflix nine times out of ten. That said, with the Heart Month hashtags flooding my twitter feed I have been inspired to start “prescribing” exercise to patients who are having trouble making healthy exercise choices. Thanks to #cardiotwitter I also have a couple of interesting studies to show patients on the benefits of running.

One observational study at the London Marathon found an approximately 4-year reduction in vascular age associated with training for and completing the race among first-time runners. Most of these people ran 6 to 13 miles per week for the 4-5 months leading up to the race. [1] A separate, outcomes-focused meta-analysis published in 2019 analyzed data from 14 studies and found a 27% risk reduction of all-cause mortality associated with running. The authors concluded that mortality risk reduction was seen with running even just once per week. [2]

Heart disease is the nation’s leading cause of death, but it doesn’t have to be. February is American #HeartMonth to reminds us that we can fight back by making healthy choices: being active, eating healthier, and going for that occasional run.

“Run, Forrest, Run!” – Effects of Cardiovascular Exercising on Mental Health

running

If life gave me a box of chocolates, I am pretty sure I would eat them all. As a basic science researcher, I am all too familiar with burn-outs and stress, and more recently to the effects of stress-induced anxiety. So, I started running. I ran when my worries got too overwhelming, I ran when I had a bad day in the lab. Next thing I knew, I was running for pleasure. And this is something I did not see coming, especially because I hated running before!

Long before medications were available or even prescribed for mental or emotional disorders, exercising remained the only prescription for tacking problems of mental health by doctors.1 The AHA recommends 150 minutes of moderate-high intensity aerobic exercising a week for adults. Researchers have found this to improve balance of neurotransmitters and show effects as early as the first thirty minutes.

Here are some evidence-based effects of exercising on mental health –

  1. Stress and anxiety – Chronic stress can shrivel parts of the brain. Exercises have found to reverse this effect and even induce growth of neurons and improve synaptic plasticity in the brain.1,2
  2. Depression – Regular aerobic exercising can improve blood circulation to the brain and it is known to positively influence hypothalamus-pituitary-adrenal axis of the brain. All of this bounce back the balance of neurotransmitters, elevate mood, attenuate stress and fight back fear.3
  3. Addiction – While dealing with addiction, exercising has been shown to give a sense of control. Individuals with a tendency to be obsessive, need to fill a void quickly and exercising has shown to be effective in this regard.
  4. Hormonal fluctuations in women – Hormones estrogen and progesterone play an important role for neurotransmitter in the brain, by providing receptors for them to bind. In some women, this complex pathway can behave in a way that increases aggressive behavior which is found to be dramatically reduced by exercise. Exercising is certainly known to increase levels of tryptophan, the precursor to the happy chemical serotonin. This helps in dealing with the constant fluctuations of hormones during a cycle.1
  5. Attention deficits – Aerobic exercising has been successful with disorders of distractions, improving focus, concentration and memory of a task.

As with any given task, starting it – is always a challenge. If you are someone like me who is a novice at running, or the thought of running itself induces fear and anxiety – then start with small steps. Take a walk, slowly increase that to brisk walking and when you feel comfortable start jogging. It doesn’t necessarily even need to be running – jumping rope, biking, throwing ball – any activity that spikes your heart rate are good.

So, will you run away from your problems?

A New Year, A New Story: Tips for a Healthy Lifestyle in 2019

A new year presents a new opportunity for improvement. Each year, thousands of advertisements beckon us to join or buy the most recent fitness and wellness craze – wearable technologies, personal coaching, pea protein and oat milk. However, if trends are not your thing, you may find it reassuring that “traditional” fitness and wellness strategies (e.g., training for a 5K walk/run, taking the stairs instead of the elevator, and reducing your sugar intake) can also be re-imagined and integrated into your daily routine leading to a healthier, and likely happier you.

Perhaps contrary to the many images trying to sell wellness products, adopting fitness and wellness strategies are equally if not more important for those who are living with a chronic disease. In November 2018 at the American Heart Association Scientific Sessions, the Physical Activity Guidelines were updated and, for the first time, specified that physical activity can help to manage chronic conditions including decreasing pain, reducing the rate of progression for high blood pressure and diabetes, reducing anxiety and depression, and improving cognition in those with chronic comorbidities. These critical health outcomes symptoms are particularly important for adults living with HIV, who tend to experience worse symptoms than many living with other chronic illnesses – and consequently, they may stand to benefit the most from increased and improved physical activity.

However, in addition to physical activity, nutritional intake is a critical part of improving health and wellness among adults living with HIV. A recent practice paper of the Academy of Nutrition and Dietetics found that nutritional status affects the overall health and longevity of this population. They suggest that improved diet can lead to reduced blood pressure, obesity, and diabetes, which will result in improved cardiovascular health. Lead author of the report, Amanda Willig, RD, PhD, from the University of Alabama at Birmingham, suggests that when anyone (especially someone with a chronic disease such as HIV) is starting to adopt a new diet to “Remember, the enemy of good is perfect. A perfect diet is not needed to see big changes in your health.”

So what are the good diet changes needed to improve health? Regardless of one’s HIV status, Dr. Willig’s recommendations on healthier eating are the same: “Watch your portion sizes, try to eat vegetables every day / fill ½ of your plate with vegetables at meals, limit the amount of sugar in your diet, and choose water over sugar sweetened beverages like soda, sports drinks or sweet tea.”

However, for those with HIV, there are some special considerations. While the evidence is still emerging, Dr. Willig indicated that those with HIV may need more Vitamin D than they did prior to their HIV infection for their overall health.  And if one’s CD4+ T-cell count is less than 250, they may want to avoid eating raw or undercooked meat and seafood, as they be at higher risk for food poisoning. Additionally, for the growing number of people living with HIV who are over 50, they may need to increase their protein intake from 0.8 grams per kg per day to 1.2 grams per kg per day. This will help with maintaining muscle mass and preventing bone loss.

Yet whether you are decreasing your portion size or increasing your daily protein intake, changing behavior can be hard and as we age, it can seem complicated and sometimes discouraging. In addition to seeking help from registered dietitian or a Physician Nutrition Specialist who can help you decide which lifestyle nutrition plan is best suited to you, Dr. Willig also suggested several tips for adopting a healthy diet in 2019 (see insert).

 

Dr. Willig’s Tips for Adopting a Healthy Diet in 2019

  • Keep a food diary for 3-4 days to learn not just what you are eating but why.
  • Start with the small steps that can produce big changes, such as cutting out sugary drinks or not eating during the night.
  • Regardless of the nutrition plan, portion sizes still matter. One can eat too many of the “right” foods, so learn what a portion of the foods you eat actually looks like.
  • Make sure your nutrition plan fits your lifestyle. If you want to cook, you can to experiment with baking and sautéing instead of frying foods. If you travel often, learn to read nutrition labels and restaurant nutrition information to avoid eating too many calories.

 

Additional strategies can be found on the American Heart Association’s Healthy Living Website.

As you start to navigate how to start the year committed to becoming healthier you, there will undoubtedly be challenges – busy schedules, competing demands, mood, weather and so on. But you can overcome them and take small steps to become a healthier you in 2019. As you start this journey, consider the words of writer Alex Morritt, “New year — a new chapter, new verse, or just the same old story? Ultimately we write it. The choice is ours.” The new year has just begun, and regardless of your age, sex, health status, or neighborhood in 2019 you get to write your own story – one in which you relentlessly pursue a healthier you.

Should Doctors Be Role Models For Their Patients “Showing, Rather Than Just Telling”

Last year, the grand round speaker was a renowned physician in his field. He gave us an excellent presentation related to heart disease prevention and lipid management. However, the audience were surprised with the fact that the speaker was obese, at least 50 lb. overweight. I invoke this anecdote to buttress my argument that physicians need to be role models to inspire confidence in their patients. It is a fact that healthy physicians make better role models for patients. Whether doctors avoid smoking, eat right, exercise, or maintain a proper weight can influence how they talk with patients about making lifestyle choices.

As an interventional cardiology fellow, I advise the importance of maintaining a healthy lifestyle to my patients on daily basis. However, the majority of us fall guilty of neglecting what the American Heart Association recommends of 30 minutes aerobic activity five times a week. One of the biggest reasons for not maintaining a healthy life style is time! Long working hours, interrupted sleep, travel, deadlines, and lack of proper work/life balance, are all obstacles that prevent from leading a healthy lifestyle.

How can we maintain healthy lifestyle with limited hours in a day? We often set unrealistic goals (i.e. losing a certain number of pounds at the end of the year, increase muscle mass to 40%, decrease waist size by 4 inches in 6 months, etc.). Therefore, setting up short-term goals is measurable and more effective. Also, changing a few habits throughout the day can have a remarkable impact on your health and fitness. In general, doing little things on a regular basis is better than nothing.

At work, try to park at the farthest spot in the lot or parking garage to gain few extra steps, use the stairs instead of the escalator, avoid high-carbohydrate diet and snacks, and protein shakes for snack and between meals. The “power of 5-minutes;” if you are in the cath lab or clinic, try to take 5 minutes for lunges, burpees, squats, sit ups, or pushups in an empty patient room or locker room. Don’t leave work at rush hour! Instead, find a place in the hospital to do 30 minutes of exercises until traffic is better then leave to go home.

At home, try not to eat 3 hours before bedtime. Avoid high-carbohydrate snacks between dinner and bedtime. Try to avoid checking your phone or answering emails after 8 pm. Go to bed early, get up 30 minutes earlier than usual and do quick morning exercises. If you have a gym membership and you never had the time to go, early morning before work is the best time.

The majority, if not all, of the cardiologists go to meetings and conferences. I find a lot of downtime during conferences that can be used to exercise. Before starting your day, spend one hour in the gym. This can be done almost at the end of the day if you are not a morning person. Have protein bars, nuts in your bag so you can snack on during the day. Avoid muffins, cakes, and candies that are often served at the exhibit halls. We have seen multiple photos on social media tagged with the hashtag “#EscalatorShame” with escalators packed with cardiologist! Use the stairs not the escalators at the convention center.

Don’t expect immediate results! Do little things when you can, as much as you could, and I guarantee outstanding results. So next time we tell our patients to exercise or lose weight, we can reflect on our personal experience and give them the best advice.
