A Cardiologist’s Overview of Beta-Blockers

Beta Blockers

Most healthcare providers prioritize addressing symptoms over the underlying causes of disease. Beta-blockers, a medication frequently used for hypertension and irregular heart rhythms, have gained widespread acceptance in our current medical paradigm. Yet, upon peeling back the surface layers, the narrative around these drugs unveils itself as more intricate than what first meets the eye.

Often hailed as reliable remedies for various heart conditions, beta-blockers – scientifically known as beta-adrenergic blocking agents – are used by millions. But a careful look is necessary. While they can relieve symptoms, these drugs interact with our bodies in complex ways, potentially leading to complications and side effects. This is a more nuanced story concealed within their common usage.

It’s increasingly clear that beta-blockers are overprescribed, appearing on a disproportionately large number of prescription pads across the nation. This “pill for every ill” approach glosses over the complexity of our biological systems and sidesteps in addressing the origins of our health problems.

In challenging our prevailing ‘medication-first’ mindset, this exploration delves into the varied types, uses, effectiveness, and potential side effects of beta-blockers. Advocating a broader, patient-centric strategy that values the body’s innate healing capabilities, this article provides an expanded understanding of beta-blockers for those who prefer addressing health’s root causes over its symptoms, aligning with a more natural health paradigm.

What is a Beta-Blocker?

When we think of beta-blockers, we automatically think of the heart. However, understanding blockers begins with a look inside our body’s complex messaging system, the nervous system. Here, a key hormone called adrenaline, or epinephrine, plays a crucial role.

Think of adrenaline as a fast-acting courier, rushing messages to different body parts to prepare for stress situations, like ‘fight or flight’. These messages are received by receptors — much like mailboxes — found throughout the body. Among these, beta receptors, particularly abundant in the heart, are of particular interest when it comes to beta-blockers.

Imagine beta-blockers as clever impersonators, acting like adrenaline. They attach to these beta receptors, effectively blocking them. This stops real adrenaline from delivering its messages, which often include prompts like ‘speed up the heart’ or ‘increase blood pressure.’ By blocking these signals, beta-blockers cause the heart to beat slower and with less force, which lowers blood pressure.

Beta-blockers are primarily prescribed for the treatment of:

  • Angina (chest pressure/discomfort)
  • Heart failure
  • Tachycardia (fast heart rate)
  • Atrial fibrillation (AFib)
  • Heart palpitations
  • High blood pressure
  • Off-label use for anxiety, migraines, and tremors

However, not all beta-blockers are identical. As a general rule, they are categorized into two main classes. The first class, non-selective beta-blockers, indiscriminately block both types of beta receptors, known as β1 and β2 receptors. The second class, called selective or “cardioselective” beta-blockers, primarily targets one specific type of receptor — the beta-1 receptors, which have a pronounced presence in the heart.

Among the prevalent members of the beta blocker family, you’ll encounter medications like:

  • Atenolol, marketed under brand names such as Tenormin
  • Carvedilol, which often goes by its generic name
  • Metoprolol, which you might see labeled as Lopressor
  • Nebivolol, often sold as Bystolic
  • Propranolol, frequently recognized by its brand name, Inderal

Beta-blockers may sound like an excellent solution for conditions like high blood pressure and irregular heart rhythms. Unfortunately, they attempt to treat or cover up the symptoms, and not the underlying cause.

Do Beta-Blockers Work?

In the medical world, the question, “Are beta-blockers effective?” often evokes a ‘Yes, most certainly,’ when really it should elicit a hesitant ‘Maybe.’ Evidence suggests they can effectively temper a racing heart or surging blood pressure. However, this pharmaceutical intervention can be like slapping a band-aid on a gaping wound. It stops the bleeding without addressing the root cause.

Plunging into the research, a revealing study scrutinizes beta-blockers impact on older adults, underscoring potential concerns. The investigation meticulously evaluates the risks and benefits of beta-blockers, particularly for mature populations. This analysis draws from diverse sources, including systematic reviews, randomized trials, and observational studies, with a total of fifteen studies—seven focusing exclusively on older adults.

Notably, when researchers considered a composite endpoint—a cluster of outcomes including death, stroke, or heart attack—beta-blockers appeared to skew the odds towards a heightened risk of these events compared to other blood pressure-lowering drugs. Moreover, beta-blockers demonstrated no clear mortality benefit compared to other antihypertensive agents or placebos.

Conflicting and inconclusive findings clouded the picture of beta-blockers impact on stroke risk. The researchers concluded with caution, stating that the current evidence supporting beta-blockers’ benefits for high blood pressure is rather flimsy, advising against their use as the primary choice for managing hypertension in the elderly.

Echoing this sentiment, a notable 2012 study discovered no evidence of beta-blockers reducing heart disease-related mortality, heart attacks, or strokes—effectively finding no extension of life. More recent research corroborates this, showing that individuals on beta-blockers had a similar life expectancy to those not on the medication.

Further disrupting conventional wisdom, a comprehensive Swedish study probed the long-term effectiveness of beta-blockers in heart attack survivors. Examining medical records of over 43,000 heart attack patients, the research revealed no cardiovascular health advantage for those who continued beta-blocker usage beyond the first year.

More research raises eyebrows about the benefits of beta-blockers for heart failure patients with better heart pumping function, known as ejection fraction. The study scrutinized over 400,000 older adults in the U.S., discovering that while beta blockers can benefit patients with weaker heart pumping function, the same might not hold for those with stronger hearts.

Astonishingly, patients with an ejection fraction over 60% experienced higher hospitalization rates when on beta-blockers. These findings call for a nuanced approach to heart failure treatment, emphasizing the necessity to consider individual patient metrics, such as ejection fraction, before prescribing beta-blockers.

The combination of this research accentuates the concept that while beta-blockers may serve as a temporary salve, they potentially ignore the undercurrents of deeper, unaddressed health issues. It’s akin to silencing the alarm instead of extinguishing the fire.

Downsides to Beta-Blockers

The ‘fight or flight’ reaction is a crucial physiological process in our bodies, guided by adrenaline, that lets us adjust to different scenarios. Yet, when beta-blockers artificially inhibit this response, it can give rise to a range of side effects, including:

  • Extreme fatigue: Energy levels can plummet, making everyday tasks feel overwhelming.
  • Low libido: Sexual desire can dwindle, along with erectile dysfunction, impacting intimate relationships.
  • Nausea: This unpleasant sensation can disrupt daily life and dietary habits.
  • Gastrointestinal problems: Experiences of constipation or diarrhea can emerge, impacting digestion and comfort.
  • Sleep disturbances: Slumber can become elusive or interrupted, undermining rest and rejuvenation.
  • Dizziness: A sense of instability or lightheadedness can compromise balance and mobility.
  • Depression: Mood can dip, casting a gray hue over general well-being.
  • Erectile dysfunction: Men may experience difficulties maintaining an erection, leading to stress and reduced sexual satisfaction.
  • Cold extremities: Beta-blockers can decrease blood flow to the hands and feet, leading to a persistent chill in these areas despite external temperatures.
  • Weight gain: Unexpected increase in weight can occur, which may influence self-image and overall health.

More severe side effects warrant closer attention. Studies show that individuals with asthma or underlying lung conditions should use caution if considering beta blockers, as they can increase airway problems. Beta-blockers can lead to other life-threatening conditions, including the following:

  • Bradycardia: Beta-blockers may cause an abnormally low heart rate, also known as bradycardia, potentially disrupting the heart’s ability to pump blood effectively.
  • Hypotension: Beta-blockers can induce unusually low blood pressure, potentially leading to fainting and organ damage due to inadequate blood flow.
  • Worsening heart conditions: In some instances, these medications can exacerbate the very conditions they are prescribed to manage, leading to heart block and worsening heart failure.

Natural Alternatives to Beta-Blockers

Nature, in its inherent wisdom, presents us with a plethora of natural beta-blocker options to nurture our cardiovascular health, devoid of detrimental side effects. The guiding philosophy of the Natural Heart Doctor, aptly termed “Eat Well, Live Well, Think Well,” underscores this approach.

The key to fostering a natural, healthy heart rhythm lies in identifying and mitigating the root causes of inflammation that catalyze the problem. Potential culprits might encompass:

  • Subpar nutrition
  • Imbalance in hydration or electrolytes
  • A passive lifestyle
  • Deficiency in sunlight exposure
  • Insufficient sleep
  • Excessive exposure to electrosmog
  • Overwhelming stress
  • Accumulated body toxins
  • Spinal misalignments
  • Poor oral health
  • Adverse effects of medication

A comprehensive understanding of these triggers paves the way for actionable steps towards a healthier heart, aligned with the three pillars of the Natural Heart Doctor’s philosophy:

Eat Well

This pillar advocates a return to our ancestral dietary habits.

  • Emphasize organic, nutrient-packed foods such as grass-fed meat, free-range poultry and eggs, and wild-caught seafood.
  • Broaden your dietary horizons to include organ meats.
  • Incorporate whole foods, like nuts and seeds, rich in nutrients.
  • Weed out inflammatory culprits such as processed foods, refined sugars, grains, gluten, and genetically modified organisms.
  • Steer clear of foods laced with pesticides and chemicals.
  • Consider evidence-based supplements such as magnesium, potassium, berberine, or curcumin. Better yet, get everything you need in the Hypertension Complete Support Protocol.

Live Well

The art of living well requires balance and mindfulness.

  • Ensure 7-9 hours of quality sleep nightly.
  • Engage in regular physical activity, preferably outdoors, to reap the benefits of vitamin D from sunlight.
  • Maintain a clean environment, free from environmental toxins and mold mycotoxins.
  • Minimize exposure to electrosmog by curbing electronic use and reducing contact with WiFi, Bluetooth, and other forms of radiation.
  • Obtain regular chiropractic care.
  • Team up with a holistic dentist to address dental health.

Think Well

Fostering mental wellness is instrumental in maintaining a healthy heart rhythm.

  • Carve out a tranquil mental haven and equip yourself to handle stress effectively.
  • Nurture positive relationships while setting firm boundaries against toxic ones.
  • Partake in activities that fuel your joy and passion.
  • Cultivate an attitude of gratitude, seeking positivity in your day-to-day life.

About Dr. Lauren Lattanza NMD, FACC

Dr. Lattanza Office Visit with Patient

As a Naturopathic Physician, I am trained to treat the whole person and get to the root cause of disease.

I went to Arizona State University where I graduated with a bachelor’s degree in psychology with a depth in physiology and minor in Spanish. After my undergraduate degree I was working on prerequisite classes towards medical school, which is when I came to learn that my values identified best with the principles of naturopathic medicine. I knew that I wanted to help patients identify the causes of disease and be able to offer treatments which would improve their health rather than simply treating symptoms.

I dedicated the next 4 years to the Southwest College of Naturopathic Medicine in Tempe, Arizona where I attained my Doctorate of Naturopathic Medicine. I served as Class President all 4 years, Board of Trustees – Student Trustee, spoke as the Club President for our branch of Toastmasters, and was voted by my peers and attending physicians to earn the Outstanding Leadership Award for the Class of 2020. Throughout medical school I took it upon myself to work alongside MDs, DOs, chiropractors, and functional medicine practitioners in addition to naturopathic physicians.

As a Spanish speaking student, I was able to volunteer with community clinics around Phoenix and provide free healthcare to low-income families. Due to this combined exposure, I came to find my passion in treating cardiometabolic and digestive disorders that are all too common, yet largely preventable. I took the opportunity to learn the broad spectrum of healthcare so I can ensure that I am able to provide my patients with the best options.
