Let’s add Stress Reduction as the 8th step in the American Heart Association’s “Life’s Simple 7”

February is Heart Month!  An entire month dedicated to heart disease awareness in our community.  During this month, we also educate the community on why heart disease is a women’s biggest threat.  After all, heart disease takes more lives than all cancers combined.  Globally, that equates to one woman dying every 80 seconds.  More recently, research has revealed an emerging heart disease epidemic in young women resulting from uncontrolled risk factors such as obesity, blood pressure, elevated cholesterol and diabetes.

The good news is that 80% of heart disease can be prevented through risk factor management – this journey begins with a baseline assessment with a clinician.  Starting this journey early is critical – research has demonstrated that if a woman can reach 50 without developing a major risk factor for heart disease, her lifetime risk for heart disease is only 8%.  By contrast, women who have 2 or more risk factors for heart disease at 50 have a 50% risk of developing heart disease.

Heart month is a great time to start your journey to #knowyournumbers.  The three most important numbers to check are:

  • Blood Pressure
  • Cholesterol
  • Blood Sugar (A1C)

It’s also a great time to review your diet and exercise plan with your physician.

Furthermore, in women, an increasingly important aspect of cardiovascular health is the presence of psychological, psychosocial, and emotional stress.  Well-established epidemiological data has shown that psychological risk factors such as anxiety, depression, work-related exhaustion, or perceived home stress are significantly associated with heart attacks in women (1).  Another large study of young women presenting with heart attacks revealed that women reported higher amounts of perceived stress before their heart attacks symptoms compared with men. Overall, women reported worse baseline physical and mental health before heart attacks compared with men (2).  Therefore, an important assessment of a woman’s current emotional health status is imperative in my initial cardiac workup, particularly for women.

During the initial consultation and subsequent follow-up visits, I focus on learning details about my patients’ lifestyle habits including eating patterns, physical activity/exercise routine, sleep hygiene, and stress levels.  The key is to begin the discussion to open the door to awareness of how one’s lifestyle could be setting them up for the greater cardiovascular risk. The American Heart Association (AHA) has created a campaign for workplace health called “Life’s Simple 7” which defines ideal cardiovascular health in terms of seven risk factors (Life’s Simple 7) that people can improve through lifestyle changes: smoking status, physical activity, weight, diet, blood glucose, cholesterol, and blood pressure.  While I have leaned on AHAs “Life’s Simple 7”, I have added a very important 8th step to reduce cardiovascular risk in my patients: Reduce Stress.

When it comes to my women patients, I have found that they are usually suffering from a compounded impact of accumulated stress from both families, interpersonal relationships, and/or work.   To help improve mental health, I recommend practicing the 4-7-8 breathing technique, prioritizing self-compassion, and focusing on gratitude.  These simple steps help to create the mindfulness that helps mitigate stress and its potential impact on the heart.

The 4-7-8 breathing technique popularized by Dr. Andrew Weil in the West is based on the ancient Indian yogic breathing technique called Pranayama. This technique can slow down the nervous system that controls the “stress response” and in turn enhance the relaxation response in the body and the heart.   It is easily accessible for my “busy” women patients as it can be performed from any location without any equipment.  The goal is to ensure your exhalation is twice as long as your inhalation.

While there are officially 8 total steps to use this technique, I often ask my patients to simply inhale for the count of 4 in the nose, hold for a count of 7, and exhale for a count of 8 through the mouth.

Self-compassion is another effective way to enhance well-being and reduce burnout. Self-compassion is the act of directing compassion towards oneself when dealing with a failure, a personal struggle, or negative thoughts about oneself. Self-compassion leads with kindness and understanding instead of self-criticism and self-judgment in response to personal shortcomings.  Recent studies on self-compassion have revealed a direct relationship between self-compression and feelings of greater well-being.

Gratitude is another way to return kindness to one’s life.  It is the quality of being thankful. The creation of a gratitude practice in one’s life may take many different forms: journaling, meditation, active daily reminders or even prayer. The common theme is opening the emotional heart to recognize and appreciate the simple pleasures in life which may be overlooked during times of stress.  It is about cultivating a sense of thankfulness for what you have rather in your life no matter how small or simple.

Last year prior to a women’s heart disease awareness lecture series I delivered, I created a handout adapted from AHA’s “Life’s Simple 7” and added the additional 8th step: Reduce Stress. [See caption below] The details of how to actually begin that journey of self-awareness of perceived stress as well as important stress reduction techniques can now be found in this blog and hopefully will find their way to our patients.

Legacy

Dr. Elijah Saunders was born in Baltimore City in 1934. As a young student he received a BS degree from Morgan State College in 1956 and he received his MD degree from the University of Maryland School of Medicine in 1960. During his medical studies, he was one of only four African-Americans in his class of 140 students and was instrumental in helping to desegregate the medical wards. He then went on to become the first African-American resident in internal medicine at the University of Maryland School of medicine and the first African-American cardiologist in the state of Maryland in 1965. 

Following fellowship, Dr. Saunders led a successful private practice for the first 20 years of his career before he returned to the University of Maryland as a professor in Cardiology, where he pursued research on hypertension among African Americans. For many years, he led the Hypertension Division in the Department of Medicine. His critical research illuminated that ethnicity may influence the response to certain types of antihypertensive medications. As a result of his research and lobbying, it is now standard for trials to require African Americans to be included in research. Over his career, he published more than 50 peer-reviewed articles and eight books.

Beyond his many achievements, including increasing African American representation in cardiovascular drug trials, being a founding member of the Association of Black Cardiologists, and co-founder of Heart House of the American College of Cardiology; Dr. Saunders was known for his positive demeanor, caring disposition, and gentle spirit. As a young black man growing up in Maryland with an interest in cardiology, Dr. Saunders was someone who I always admired. During my fourth year of medical school I spent an away rotation at the University of Maryland in hopes of training under Dr. Saunders, but was saddened to hear of his untimely passing prior to my arrival. However, I eagerly listened to his patient’s detailed stories regarding his intellect, compassion, dedication to health equity, and desire to bring healthcare to non-traditional spaces to reach the most at-risk populations. This experience quickly reaffirmed that Dr. Saunders was the type of cardiologist I hoped to emulate: clinically skilled, empathetic, and a leader in healthcare innovation. 

Despite improvements in health distribution inequalities, African-American communities are continuously  plagued with cardiovascular disease at an alarming rate. Some of the main contributors to the high burden of disease are the persistent and increasing degrees of limited access to healthy food, low socioeconomic status, and poor nutritional awareness.  To address this, Dr. Saunders advocated for community screening and outreach in barbershops and churches in order to engage the black community in non-traditional spaces. In 2006, he developed the Hair, Heart and Health program, an innovative program that trained barbers and hairstylists to pre-screen customers for hypertension and then make referrals for medical care.  

I believe as medical professionals we have two profound responsibilities. The first is to be an effective clinician. It is our obligation to treat and heal patients to the best of our abilities, while cultivating and promoting prevention. The second, and perhaps more important, is to go beyond the hospital walls and become an innovator in healthcare. We must identify roadblocks that may impede healthy practices, and provide sustainable solutions for these challenges. I hope that we can all mimic Dr. Saunders’s spirit for innovation and love of patient care.

Start 2021 in a Good Night Sleep

Picture source: (Kuehn 2019)

Should you make new year’s resolutions? Many may think the new year’s resolutions are meaningless. Especially after a year of frustration and uncertainty, New year’s resolutions seem less encouraging. A few small and attainable goals could help to provide a sense of purpose and improve our well-being. The most popular goals for new year’s resolutions include exercise more, eat healthier, and get rid of bad habits.

[1]Sleep deprivation is one of the common bad habits in modern society. According to a study in the Centers for Disease Control and Prevention’s (CDC) Morbidity and Mortality Report, 1 in 3 Americans don’t get enough sleep on a regular basis. To promote optimal health and well-being, the American Academy of Sleep Medicine and the Sleep Research Society recommend at least 7 hours of sleep each night for adults aged 18-60 years old. The adverse effects of sleep deprivation (less than seven hours per day) include obesity(Beccuti and Pannain 2011), diabetes(Shan et al. 2015), high blood pressure(Gangwisch et al. 2006), cardiovascular disease(Nagai, Hoshide, and Kario 2010; Kuehn 2019), stroke, and mental distress(Baglioni et al. 2016). It’s undeniable that having sufficient sleep is essential to our optimal health and well-being. Here are some helpful tips to start your 2021 with a good night’s sleep.

Bedroom: light, noise, and temperature

Research shows artificial light at night can disrupt circadian rhythms and cause adverse effects on sleep(Aulsebrook et al. 2018). A dim bedroom environment can help the body to recognize the time to rest. Electronic devices emit blue lights, many studies show that blocking blue light is beneficial for patients to suffer from insomnia(Janků et al. 2020). Restricting electronic devices before sleep or using blue-light blocking approaches are helpful to maintain a good quality sleep.

Noise can also affect sleep(Basner and McGuire 2018). Try to reduce noise in the bedroom environment could fall asleep faster and minimize disruption during sleep. Both environmental and body temperature impact sleep duration and sleep quality(Troynikov, Watson, and Nawaz 2018). Increased bedroom and body temperature decrease sleep quality. Finding a comfortable temperature for yourself will improve sleep quality. For most people, the desirable bedroom temperature is around 70 ˚F (20 ˚C). Taking a good bath or shower before bed will prepare the body to adjust to a favorable temperature for sleep.

De-stress: mentally and physically

Most of us have experienced some form of insomnia when we have something in our minds. Integrative approaches to insomnia such as mind-body therapies (mindfulness mediation, yoga, tai chi) have been shown beneficial to de-stress the body as well the mind(Zhou, Gardiner, and Bertisch 2017). Exercise is beneficial for the overall well-being, can improve the quality of sleep(Kelley and Kelley 2017). Various approaches can help relax the body and mind, finding your favorite ones requires a little bit of exploration.

Routine: timing and time

We are creatures of habits. Especially when it comes to sleep. Disruption of the circadian clock adversely affects sleep, which causes cardiovascular diseases(Chellappa et al. 2019). Cultivating a wake-up and night-time routine will have profound impacts on the overall performance. When to go to bed is different for everyone. Anecdotally, it’s best to go to bed earlier and wake up early each day. This may not work for everyone’s schedule. Keeping the recommended amount of sleep is more important than strictly enforcing yourself against your circadian clock.

Food and drink

Investigation of the impact of food choice and consumption on sleep is an emerging field. Early clinical studies investigated the effects of certain macronutrients such as carbohydrate, protein or fat on daytime alertness and nighttime sleep. Some popular sleep–promoting foods, such as milk, fatty fish, cherries, and kiwifruit have been reported(St-Onge, Mikic, and Pietrolungo 2016). Avoid late caffeine consumption(Clark and Landolt 2017) and alcohol(Thakkar, Sharma, and Sahota 2015) are common practices to improve sleep quality.

All of the above are potential strategies for sleep improvement. Making small adjustments in your sleep hygiene routine could have a promising outcome. The key is to start small and stick to it until it incorporates into your day-to-day life.

Building Your Brand: Research Career Planning and Scientific Writing

AHA 20 had a fantastic session titled “Building Your Brand” and it provided excellent insights on how to be a successful researcher in academic medicine. Panel participants Dr. Erin Michos, Dr. Louise McCullough, Dr. Andrew Landstrom, and Dr. Pradeep Natarajan shared their stories on how they got involved in research and the lessons they learned along the way. While the session focused on fellows in training, I will present my viewpoint on how these general principles are applicable to early-career physicians (ECP). Based on this session, I have developed a step by step approach.

When is the right time to get involved in research?

No doubt, it is good to start as early as possible, but it is never too late. Residency is the ideal time to get involved in the research. This head start allows you to explore different areas of research, find what interests you, and at the same time allows ample time to acquire skills needed to conduct research. For ECP, this means if you already started research during your training you are on the right track. If you were not exposed to much research during training, you can always start now.

Step#1: Start now.

How to get started?

The significance of finding the right mentor cannot be over-emphasized. It is important to meet different potential mentors and get to know them. This allows you to assess overlapping areas of interest, learn how research shaped their careers and most importantly get inspiration from their journey. For an ECP, it is important to work with different mentors that can develop you in different areas of research. These mentors can be across different institutions in the country.

Step#2: Find your mentoring team.

What skills are needed and how to acquire them?

“Writing” and “Statistics” are the two most important skills needed for any type of research. There are multiple ways to acquire these skills depending on how much time you want to invest. Most of these skills can be acquired by taking online classes or a degree program. Most academic programs offer classes in scientific writing, epidemiology, biostatistics, clinical trial design, and grant writing. For an ECP, if you think you will be doing research throughout your career, consider getting additional training through a master’s degree in clinical and translational sciences or in some cases a PhD.

Step#3: Acquire scientific writing and statistical skills.

What are the effective strategies for manuscript writing?

Writing the first draft is challenging but it is important to write it quickly and not worry about perfection. Start by writing the methods, followed by results, and leave an introduction and discussion to the end. Feedback from your mentor and collaborators will improve the paper.

Step#4: Write the first draft quickly, following this order: methods, results, introduction, discussion.

Quality or Quantity?

While it is ideal to always conduct high-quality and novel research projects, in-reality all such projects need research funding. Therefore, early in your research career, it is important to be productive and complete some less extensive projects starting from case reports, review articles, and retrospective studies. This allows you to practice the skills you acquired and get some confidence that you carried an idea from start to finish. It will build your research profile and make you a competitive candidate for grant funding in the future.

Step#5: Publish something even if it is a case report or a retrospective study.

How to build a brand?

Once you have found your mentoring team, acquired writing and statistical skills, and published at least one manuscript, it is time to develop a focus. You cannot build a brand without a focus. The first step is to find an area of research that you truly find fascinating and it typically includes ideas that you cannot stop thinking about and questions that give you an epiphany. Often, the most important research questions arise from your clinical work. Second, see if these ideas are vital from a clinical, research, and public health standpoint (significance). Third, see if you have the right environment (research team, institutional support, skills) needed to turn this idea into reality (feasibility). Often, we have to spend many years exploring different research interests and acquiring more skills (grantsmanship) before we arrive at an idea that we see ourselves developing into a brand (niche). For ECP, if you are busy clinicians with an interest in research, try your best to align your clinical interests with your research interests. Once you have established your niche, it is extremely important to stay focused so that all your time and energy is spent on developing your brand.

Step#6: Develop your niche, advance your skills, align clinical work with research, stay focused, avoid distractions.

What personality traits are needed?

A key trait is showing persistence despite multiple failures as it is not uncommon to have your first manuscript rejected by a journal or multiple journals. Having the persistence to learn from this experience, improve your manuscript and resubmit, is necessary. For mentees, it is important to develop a “can-do attitude”, be authentic, honest and follow through on commitments.

Step#7: Develop persistence, learn from failure, be a good mentee.

I hope you found these steps useful for building your brand in research. “The game has its ups and downs, but you can never lose focus of your individual goals and you can’t let yourself be beat because of lack of effort.” (Michael Jordan)

DAPA-CKD: Is SGLT2i the ANSWER? Will the guidelines change?

Over the past years, series of clinical trials prove the beneficial effect of glucose cotransporter 2 (SGLT2) inhibitors in reducing the risk of cardiovascular events in people with type 2 diabetes mellitus. The results from these trials were consistent, significant, and demonstrated a considerable reduction in heart failure hospitalization among patients who used SGLT2 inhibitors, whereas the benefit on atherothrombotic events such as myocardial infarction and stroke was moderate.

Similar findings from The Canagliflozin and Renal Events in Diabetes With Established Nephropathy Clinical Evaluation trial (CREDENCE) were obtained for patients with type 2 diabetes mellitus and chronic kidney disease who are exceptionally at higher risk for cardiovascular disease. In CREDENCE trial, Canagliflozin reduced the risk of chronic kidney disease, cardiovascular death or hospitalization, myocardial infarction, and stroke. Although diabetes is not the only cause of chronic kidney disease, and people with chronic kidney disease are still at increased risk for cardiovascular disease, regardless if they had a preexisting history of cardiovascular disease or not. Therefore, its essential to implement guidelines that recommend the use of certain therapeutics as routine treatment for primary and secondary prevention of cardiovascular disease in patients with chronic kidney disease, regardless of their diabetes status.

During #AHA20, I enjoyed attending the online session by Dr. John McMurray, where he shared scientific breakthrough results from the Dapagliflozin And Prevention of Adverse Outcomes in Chronic Kidney Disease (DAPA-CKD) Mega-Trial. The session reported the results of the effect of dapagliflozin on prespecified kidney and cardiovascular outcomes in patients with chronic kidney disease with and without diabetes. The DAPA-CKD trial was a randomized, double-blind, placebo-controlled, multicenter trial, where adults with or without type 2 diabetes, with estimated glomerular filtration rate (eGFR) between 25 and 75 ml/min/1.73 m2, and a urinary albumin-to-creatinine ratio (UACR) between 200 and 5000 mg/g were eligible for DAPA-CKD trial. In this trial, patients were randomized to dapagliflozin 10 mg once daily or placebo with follow up at 2 weeks, 2,4, and 8 months and at 4 months intervals thereafter. The primary composite outcome was the time to the first occurrence of any of the following: > 50% decline in eGFR, onset of end-stage renal disease, or death from kidney or cardiovascular disease. Moreover, secondary outcomes were: 1) kidney composite outcome identical to the primary endpoint with the exception of death from cardiovascular death 2)( a cardiovascular composite outcome consisting of hospitalization for heart failure or death from cardiovascular  causes; and 3) death from any cause.

 

Effects of dapagliflozin on prespecified clinical outcomes according to the baseline history of cardiovascular disease.

 The DAPA-CKD trial found that among patients with cardiovascular disease who received dapagliflozin, the primary composite outcome occurred in 11.2% participants, while the primary outcome occurred in 17.2% in participants who were in the placebo group, (HR 0.61; 95% CI, 0.47-0.79) and the corresponding numbers in people without cardiovascular disease were 7.9% and 12.9% respectively, (HR 0.61; 0.48-0.78).

The DAPA-CKD trial also found that for both the primary and secondary prevention patients, the event rates favored dapagliflozin for all components of the primary and secondary outcomes, although reduction in cardiovascular risk was not statistically significant.

DAPA-CKD Figure

Additionally, among patients with cardiovascular disease, cardiovascular death or hospitalization for heart failure occurred in 9.3% of participants in the dapagliflozin group and 12.8% of participants in the placebo group, (HR 0.7; 0.52-0.94) and the corresponding numbers for patients without cardiovascular disease were 1.8% and 2.7% respectively, (HR 0.67; 0.40-1.13). The observed reduction in cardiovascular risk for these two groups was driven by reduction in heart failure hospitalization which occurred in 4.1% of participants in the dapagliflozin group and 7.3% participants in the placebo group with cardiovascular disease and the corresponding numbers for patients without cardiovascular disease were 0.3% and 1.0% (HR, 0.31; 0.10-0.94) respectively. These results show that dapagliflozin reduced the risk of adverse kidney outcomes irrespective of baseline cardiovascular disease status. Moreover, the mortality benefit from dapagliflozin as demonstrated from the DAPA-CKD study supports the findings of the DAPA-HF trial. In summary, dapagliflozin reduced the risk of kidney failure, death from cardiac disease or hospitalization for heart failure, furthermore, it prolonged survival, in people with chronic kidney disease, irrespective of the presence of a concomitant cardiovascular disease.

 

What is next?

The data from DAPA-CKD trial for dapagliflozin effect on patients with cardiovascular disease and chronic kidney disease is clear, but we have so much work to do. Is Dapagliflozin the answer? How would this change the guideline directed medical therapy (GDMT) for the care of patients with an increased heart failure, cardiovascular or chronic kidney disease risk, regardless of their glycemic status?

Last Day of #AHA20: COVID-19 Galore!

The last day of the amazing #AHA20 featured a series of COVID-19-related research presentations.

First, data from the AHA COVID-19 Registry, a large database collecting data about COVID-19 patients and outcomes around the country, were shared. The registry includes data from 109 hospitals and over 22,500 records of patients who were hospitalized with COVID-19. Notably, large numbers of COVID-19 patients in this registry had cardiovascular risk factors such as hypertension and diabetes. Prior cardiovascular disease was also common. The disease was additionally noted to have a high morbidity and mortality rate, with more than 20% of hospitalized COVID-19 patients requiring mechanical ventilation.

One interesting study examined racial and ethnic differences in the AHA COVID-19 Registry of patients hospitalized with COVID-19, focusing primarily on the association of these factors with in-hospital death as the primary outcome and secondary outcomes such as major adverse cardiovascular events (MACE: death, myocardial infarction, stroke, new onset heart failure or cardiogenic shock) or COVID-19 cardio-respiratory disease severity scale. Notably, Black and Hispanic patients accounted for >50% of hospitalizations in this Registry, suggesting significant over-representation of Black and Hispanic patients compared with the census demographics in their areas. Cardiovascular risk factors such as obesity and hypertension were also more common in Black and Hispanic patients. Mechanical ventilation and need for renal replacement therapy were more likely in Black patients. Overall in-hospital mortality was high at 18.4%, and particularly high for those older than 70 years old.

In fully adjusted models taking into account age, medical history and sociodemographic features, there was no statistically significant difference in mortality and MACE among different racial or ethnic groups, though Asian patients had a higher COVID-10 disease severity on presentation. These findings suggest that though race and ethnicity are not independently associated with worse in-hospital outcomes in COVID-19 patients, Black and Hispanic patients bear a greater burden of morbidity associated with COVID due to their disproportionate representation among patients hospitalized with CVOID-19. This study was simultaneously published online in Circulation.

One additional study examined the association between body mass index (BMI) with a composite of in-hospital death and/or mechanical ventilation (primary outcome), as well as with MACE (a composite of in-hospital all-cause death, stroke, heart failure, myocardial infarction), deep vein thrombosis and renal replacement therapy (secondary outcomes). Patients with a higher BMI were more likely to be admitted to the hospital with COVID-19. In analyses adjusting for age, sex, ethnicity, comorbidities, cardiovascular disease and chronic kidney disease, higher class obesity was associated with higher likelihood of in-hospital mortality or mechanical ventilation. MACE was not associated with obesity class. Deep venous thrombosis or pulmonary embolism were not associated with obesity class. Class I, II and III obesity, however, were noted to have a higher likelihood of need for mechanical ventilation, regardless of age. Moreover, when stratified by age, BMI >40 kg/m2 was associated with a higher risk of in-hospital death only in lower age groups (<50 years old). These findings suggest that better public health messaging may be required for younger obese individuals who may underestimate their own risk related to COVID-19. This study was also simultaneously published in Circulation.
