Heart Health

When it comes to protecting your heart, most doctors focus on outdated tests that offer little more than a snapshot of your current condition. But at Natural Heart Doctor, we believe prevention is the key to a 100 Year Heart—and that starts with the right testing.

Mainstream medicine may push coronary CT scans and nuclear stress tests, but these are not the tools that predict or prevent heart attacks. In fact, they often lead to unnecessary radiation, false positives, and risky procedures.

Let’s explore the tests that actually matter—so you can take action before a problem strikes.

✅ Top Tests You DO Need for Heart Health

1. Oxidized LDL (OxLDL)

This test measures damaged LDL particles—those most likely to trigger plaque buildup in your arteries. High LDL alone doesn’t tell the full story. But oxidized LDL? That’s where inflammation and oxidative stress meet, and it’s a red flag we don’t ignore.

Why it matters: OxLDL reveals your real heart attack risk—long before any imaging test does.

2. High-Sensitivity C-Reactive Protein (hs-CRP)

Inflammation drives cardiovascular disease. hs-CRP is a powerful marker of low-grade, chronic inflammation. If it’s elevated, your heart and blood vessels are under silent attack.

Why it matters: hs-CRP can rise years before a cardiovascular event, giving you time to reverse the damage.

3. Omega-3 Index

Omega-3 fatty acids protect your heart, brain, and immune system. This test tells you if your levels are optimal—or dangerously low. If you’re not eating wild seafood or taking high-quality supplements like Wild Salmon Roe, you may be deficient.

Why it matters: Higher omega-3 levels = lower risk of heart attack and sudden cardiac death.

4. Advanced Lipid Panel (Beyond Total Cholesterol)

Forget total cholesterol. What you really want is an advanced breakdown—LDL particle size, ApoB, Lp(a), and triglyceride/HDL ratio. These markers offer deep insight into your metabolic and cardiovascular risk.

Why it matters: Total cholesterol doesn’t predict heart attacks. These advanced markers do.

5. Full Environmental Toxin Panel (Including Mold Mycotoxins)

Your heart doesn’t just suffer from bad food or lack of exercise. It also suffers from your environment. Hidden mold, heavy metals, and chemicals like BPA silently damage your cardiovascular system every day.

Why it matters: You can’t heal in the same toxic environment that made you sick.

6. Intracellular Vitamins and Minerals

Inside the cell is where the action happens. This test goes beyond basic blood work to assess the actual nutrient levels within your cells—where they do their work. Key nutrients like magnesium, B vitamins, copper, selenium, and zinc must be optimized for proper mitochondrial function, energy production, detoxification, and cardiovascular health.

Why it matters: Normal blood levels may look fine, but inside the cell could tell a very different—and much more important—story.

7. Leaky Gut Test (Intestinal Hyperpermeability)

Leaky gut, or intestinal hyperpermeability, is a hidden driver of systemic inflammation and autoimmunity. When the gut barrier breaks down, bacterial toxins and undigested food particles leak into the bloodstream—triggering immune reactions that damage the blood vessels and heart.

Why it matters: A leaky gut leads to a leaky heart. Testing helps uncover this root cause of inflammation and allows us to heal the gut—and in turn, protect the heart.

🚫 Tests You DON’T Need

1. Coronary CT Scan

This test exposes you to ionizing radiation and only shows existing calcium buildup. It tells you where you’ve been, not where you’re going. It can’t predict a future heart attack—and often leads to unnecessary procedures or anxiety.

Why we don’t recommend it: Radiation risk + limited predictive value = not worth it.

2. Nuclear Stress Test

This test looks at blood flow during exercise, but again, involves radiation and only picks up major blockages—not the small plaques that actually rupture and cause heart attacks. Worse yet, a “normal” test result can provide false reassurance.

Why we don’t recommend it: It won’t catch the most dangerous kind of heart disease—the kind you don’t feel.

🎯 The Natural Heart Doctor Approach

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.
