Dr. Gunn offers Lifestyle Longevity Program

Your Health, Your Body, Your Heart. It’s Your Life

Wellness is a dynamic process that often changes with age and is influenced by genetics, lifestyle habits and circumstance. Learning the current state of your wellness improves your knowledge base, helps you set goals for your health, learn about your options and empowers you to make better choices for a longer and healthier life.

My Goal:

Provide my patients an accurate and educated picture of their physical and emotional wellness and a basic understanding of the role that cholesterol, inflammation, arterial plaque and genetics play in their risks for heart disease, stroke, diabetes, dementia and auto-immune diseases. Further, understanding the importance of their intestinal biome, nutrition, weight, exercise, stress management, meditation, smoking, and blood pressure is essential for achieving an optimal quality of life and improved sense of well-being.

With this foundation I am able to provide my patients with a proactive lifestyle plan that, if adapted, will have a dramatic effect on lowering their lifetime risks of having a future cardio-vascular event (heart attack or stroke), complications of diabetes, cognitive decline and Alzheimer’s. Hopefully, this will be a lifetime journey. The process isn’t complicated, but success does require a constant commitment to learning and being consistent in practicing their new LifeStyle habits. I am constantly uplifted by the achievements of my patients. At times, their results are just plain awesome. GOAL: Your Healthspan will equal your Lifespan (Longevity)

After watching this short and informative video, 'Just a Little Heart Attack', featuring Elizabeth Banks, review all the articles below and learn how your actual risk for heart disease, stroke or diabetes can be accurately assessed and managed.


My Lifestyle Longevity Program is probably unlike any other you may have previously experienced. One major difference is that I have been utilizing Doppler vascular ultrasound to diagnose atherosclerosis (arterial plaque) for well over 25 years. I have measured the location, amount and type of plaque of the carotid arteries in the neck (risk for stroke) in over 2000 patients. Non-invasive vascular ultrasound can establish two important landmarks: (1) the actual presence of disease (plaque) and (2) if plaque is present, a baseline for future comparison. This simple office procedure provides the ability to classify a patient as more accurately being high risk (plaque) or low risk (no plaque) for a future heart attack or stroke.

My goal: prevent Heart Attacks and Strokes by diagnosing plaque, stabilizing its progression and potentially reverse and eliminate it. The use of Doppler vascular ultrasound over time provides me an insight as to the effectiveness of a patient’s lifestyle changes and their medical treatment program. In other words: How a patient is really doing?

Bottom Line: Heart Attacks and Strokes can be Prevented.

Plaque (atherosclerosis or hardening of the arteries) is an inflammatory disease that occurs in the wall of arteries (the vessels that carry blood and oxygen from the heart to the entire body). Plaque is the cause of nearly all heart attacks and strokes.

Cholesterol is a type of lipid (fat) molecule that is that is necessary for life, because it is an essential structural component of all animal cell membranes. In addition to its importance for the body’s cell structure, cholesterol also serves as a precursor for the biosynthesis of steroid hormones, bile acid[6] and vitamin D. However, being a fat molecule cholesterol does not mix with blood (water), as it would cause immediate clotting. Therefore, for cholesterol to reach all the body’s cells it must be transported by water-soluble molecules called lipo-proteins. Lipo-proteins come in many molecular sizes and it is the size of the molecule that determines how it is classified. There are five major classifications of lipo-proteins: HDL, LDL, IDL, VLDL and ULDL (chylomicrons). Within each class there are also many varying sizes. However, it is primarily two to three subclasses of LDL molecules that are responsible for the development and progression of plaque within the arterial wall: LDL-p (particles), sdLDL-C (small dense) and Lp(a)-C.

When circulating blood levels of Lp-C (cholesterol), sdLDL-C (cholesterol) and Lp(a) (cholesterol) are elevated, they have the ability to permeate an area of inflammation within the lining of an artery and deposit cholesterol, creating a fat (lipid) pool called soft plaque. Think of plaque as a pimple-like structure that contains liquid fat (cholesterol). The capsule covering plaque may be thin (more susceptible to rupture) or thick (less susceptible). The body’s immune system can reverse the inflammation in the artery’s wall and deposit calcium making the plaque more stable (called ‘hard or calcified’ plaque).

However, without warning, the thin capsule covering of plaque can rupture allowing the fatty cholesterol deposits to leak into the blood stream causing an immediate blood clot to form at the ruptured site. If the clot is large and closes off the entire artery, a heart attack or a stroke results and emergent medical attention is required to remove the clot, if possible. The size of the clot, its location within the artery and where it travels determines the severity of a stroke or heart attack, and whether or not it is fatal. Plaque can grow slowly, rapidly, or remain stable and never cause an event, unless it ruptures. What is now understood is plaque at any stage of narrowing (stenosis) can become unstable and the capsule can break or rupture. In other words, it is NOT the plaque building up and clogging the arterial pipe that is the cause of a heart attack of stroke; it is the rupture of the plaque capsule. Often it is an area of only mild soft plaque that ruptures and without warning.

The good news is that atherosclerosis (plaque) formation is potentially reversible and even preventable! The KEY: identifying those patients who do not know they have disease (plaque) BEFORE they ever have a cardio-vascular (C-V) event and enrolling all persons who are at risk in a comprehensive prevention program.

Remember: the majority of heart attacks and strokes occur in individuals with only mild plaque in their arteries and have have a normal cholesterol panel.

My cardiovascular and diabetes risk prevention recommendations are based on a patients’ actual or measured risk. Risk classifications have been created by various heart associations and are an educated guess based on personal and family health histories and a basic cholesterol panel. Personal risk factors include age, current smoker, high blood pressure, waist measurement, diabetes, low HDL-C, high LDL-C, high triglyceride. Family history of early heart attacks and stroke and genetics are known risks. High-Risk includes anyone that has had a prior heart attack or stroke or meets certain calculated criteria. Low-Risk patients frequently have ’normal’ cholesterol levels and no risk factors. Yet low-risk people still have heart attacks and strokes. How many times have you heard about someone who is the epitome of ‘good’ health, exercises regularly, eats right, doesn’t smoke, etc. and has a sudden heart attack. How can that happen? Answer: previously unknown and untreated plaque in an artery suddenly ruptures without warning.

Recommendations for reducing future risk of a heart attack or stroke are generally referred to as either Primary or Secondary. Secondary Prevention (after surviving an event) recommendations are for high-risk patients and are generally treated more aggressively. Primary Prevention is recommended for low-risk patients and are generally less ‘aggressive’. All patients, however, are encouraged to eat healthy, lose weight (if not at an optimal BMI), exercise regularly, not to smoke, monitor their blood pressure and learn to manage stress with mindful meditation. All these risk factors (except genetics) can be successfully modified to reduce risk, if and when education, motivation, lifestyle planning and coaching are provided. The problem with this dual standard of care is the fact that nearly 50% of patients who have their first heart attack or stoke are in the low risk category.

Plaque is NOT normal! Patients who have been diagnosed with mild atherosclerosis (plaque) in their arteries on ultrasound scans are frequently told that ‘plaque is normal as they age’ and ‘not to worry’, unless it is causes a partial blockage of blood flow (to the brain or heart). Reports from mobile vascular ultrasound screening services actually state, “mild plaque is normal”.

This ‘not to worry’ belief stems from the 1970's ‘clogged pipe mentality’ of cholesterol plaque buildup causing blockage of arteries as being the main cause of heart attacks and strokes. This belief led to the development of many vascular procedures over the past few decades, including angioplasty, bypass artery surgery and insertion of stents in the heart’s arteries or removing the plaque (endarterectomy) and insertion of stents in the carotid arteries supplying the brain. However, studies have clearly shown that while pain symptoms may be improved, these procedures have failed to lower the actual incidence of future heart attacks or strokes.


The key to managing my patient’s cardiovascular and metabolic risks begins with Boston Heart Diagnostics proprietary laboratory testing. This unique in-depth level of testing provides me the insights and tools to manage my recommendations for successful improvement in their numbers – moving them into the "GREEN" zone.

I encourage my patients to participate in the Boston Personalized Nutrition and Life Plan Program and to take advantage of the coaching services of their staff Registered Dietitian Coaches. The BOSTON Life Plan Coaching Program has been critical in helping patients achieve their nutritional lifestyle goals. This coaching program is available for anyone who has completed their initial Boston laboratory testing and created their Personalized Nutritional Life Plan on the Boston website (see below).

Understanding Heart Disease
Understanding Heart Disease
Cardiovascular disease is a group of medical conditions related to the heart or blood vessels. Hypertension (high blood pressure) and atherosclerosis (buildup of fatty deposits in the arteries) are two familiar types of cardiovascular disease. Some people, including healthcare providers, refer to cardiovascular disease as ”heart disease”, although it can affect more than just your heart. Cardiovascular disease can lead to more serious conditions, such as a heart attack, heart failure, or stroke. These ‘cardiovascular events’ can result in permanent disability or even death.

Cholesterol's Role in Cardiovascular Disease

Traditionally, the risk of cardiovascular disease has been determined by simple blood tests and the presence of various risk factors. One of the common ways’ healthcare providers screen for cardiovascular disease is with a blood test called a lipid panel. This panel is typically a combination of tests used to measure the amounts of fatty substances (called lipids) in the blood and can include: total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C); high-density lipoprotein cholesterol (HDL-C); triglycerides (TG) and Non-HDL Cholesterol.

LDL-Cholesterol (LDL-C), often called “bad cholesterol,” can build up in the walls of blood vessels supplying your heart and slow or block the flow of blood, increasing your risk of developing heart disease and possibly cause a heart attack. However, not all LDL is ‘bad’. It is the ‘small size’ particles and ‘small dense’ particles of LDL that deposit cholesterol in walls of arteries promoting the formation of plaque. Treatment, including drug and supplement therapy and lifestyle changes, is aimed at lowering small and small dense LDL-C particles and raising your large alpha HDL-C particles (see Boston Heart HDL Map Test discussed below).

Traditional Lipid Testing Does Not Tell the Whole Story

Information from traditional cholesterol screening tests provides basic screening information. But research indicates that lipid panel testing alone does not predict your risk of a cardio-vascular disease event. It is only the tip of the iceberg.

Clinical trials have shown that lowering the total LDL cholesterol reduces the risk for a cardiovascular event by only 25-30% on average, meaning that standard therapy fails to address 75% of a patient’s remaining or residual risk for cardiovascular events.

Additionally, hospital admission data indicates that at least half the people who’ve had a heart attack had “normal” cholesterol levels. This “silent killer” of 50% of patients who die suddenly from a heart attack had normal cholesterol. What is wrong with this picture? There is so much more information available to be learned about a patient that can correct this statistic. Read on.
Assessing Your Risk
Assesing Your Cardiovascular Disease Risk
Boston Heart Diagnostics’ approach to cardiovascular disease risk assessment and treatment is different than any other laboratory.

First, Boston Heart Diagnostics has developed two unique tests - the Boston Heart HDL Map and the Boston Heart Cholesterol Balance Test - to uncover specific and important information about your cholesterol that offers more insight than a standard lipid panel. These special tests, along with a panel of diagnostic and genetic tests, give me guidance to help you better understand your individual risk factors and to design a personalized program of recommendations that will help you prevent, manage and potentially reverse cardiovascular disease.

Boston Heart HDL Map Test

Scientific advancements have revealed that HDL is comprised of many different sub-particles. Where standard HDL tests measures the total amount of HDL in your blood, the Boston Heart HDL Map measures the five sub-particles in HDL that range in size from very small to large. The amount that you have of each of these HDL sub-particles provides an indication of increased risk or protection of disease.

HDL-C, the “good cholesterol,” helps remove LDL-C from your blood vessels. It carries this “bad cholesterol” to the liver, where it passes out of the body. However, it is only the large alpha-1 and alpha-2 HDL particles that are protective. The smaller HDL particles are actually not healthy.

If your basic lipid panel, which only measures the total cholesterol amounts, including HDL, is normal, the Boston Heart HDL Map Test can identify if you are at risk, enabling appropriate treatment. You want as much of the large alpha-1 and alpha-2 HDL protective particles as your body can produce.

Boston Heart Cholesterol Balance Test

Each person produces and absorbs cholesterol at different rates. This can affect how your body reacts to certain therapies to lower your LDL or bad cholesterol and keep plaque from building up in your arteries.

The Boston Heart Cholesterol Balance test is the only laboratory test that can identify and measure the balance between cholesterol production (from your liver) and absorption (from your intestines). This information provides me the ability to target the right dietary changes and cholesterol-lowering recommendations at the beginning of your treatment.

Biography of Dr. Gordon Gunn
Dr. Gordon C Gunn
I chose medicine as my professional career early in life. Inspired by my father, a respected obstetrician and gynecologist, I was eager to pursue the same career path.

After earning my undergraduate education at both UCLA and USC, I received my medical degree from Baylor University College of Medicine in Houston, Texas. After completing my residency in Obstetrics and Gynecology at the UCLA Center for Health Sciences and City of Hope, I proudly served in the U.S. Air Force as the principle gynecology oncologist at Andrews Air Force Base in Washington, DC. During my tenure, I promoted the development of a new surgical technique that later became known as 'laparoscopy', a procedure that has revolutionized most surgical specialties today.

After completing my Air Force tour of duty, I moved to Fullerton in 1971 to establish my private obstetrics and gynecology practice. In 1986, I stopped practicing obstetrics and focused on developing a center dedicated to gynecology and comprehensive evaluation and treatment of the many issues in women's health care. My goal was to create a warm and attractive environment, where both my philosophy and professional standard of medical care would continue to meet the changing needs of my patients. After the years of expansion of both the physical facilities, the medical care programs and the professional staff at the Gunn Towbin Center, I decided to return to the place where I began - solo practice.

My interest in cardio-vascular disease dates back to college when I was first introduced to vascular research. In medical school I had the opportunity to train under the most prestigious cardiologists and vascular surgeons in the world. I continued to engage in vascular and cardiology research throughout my training. Over 25 years ago I introduced a wellness program to my patients. The program has grown and matured into a passion over these many years and continues to give me the privilege and opportunity to make a difference.

I am certified by the American Board of Obstetrics and Gynecology and by the Accreditation Council for Gynecologic Endoscopy, Inc. and am a Fellow of the American College of Obstetricians/Gynecologists. I am also a member in a variety of professional organizations, including American Medical Association, American Association of Gynecologic Laparoscopists, Internal Federation of Gynecologic Endoscopists, American Urogynecology Association, International Continence Society and the National Lipid Association.

I, and my wife, Andrea, have four grown children and four wonderful grandchildren. Together, we enjoy our health, our professions and the gifts that each day brings.
