Beyond Oatmeal: A More Complete Picture of Heart Health After 40

February is Heart Health Month, which means you’re likely seeing the same recycled advice: eat more oatmeal, walk more, lower your cholesterol.

Here’s what frustrates me about most heart health guidance: It’s sooo stuck in 1995!

The conversation around cardiovascular health has evolved dramatically in the past decade, but most people – and frankly, most doctors – are still using an incomplete scorecard. They’re laser-focused on one number (LDL cholesterol) while ignoring the fuller picture that actually determines your risk. While some doctors are not up to date in their heart health education, another, more pervasive problem in the US is that getting additional coverage of better testing from insurance companies is a major obstacle.

However, the reality is you have access to better information than outdated advice. You can understand what’s actually happening in your cardiovascular system—and know better how to protect it.

The Problem with the “Just Lower Your Cholesterol” Narrative

Don’t get me wrong; LDL cholesterol matters. But there’s an additional truth that the medical system is slow to acknowledge:

Even when LDL cholesterol is well regulated with statin therapy, a residual risk for cardiovascular disease still occurs (1).

Translation: You can do everything “right” according to traditional guidelines—take your statin, hit your LDL targets—and still be at significant risk for a heart attack or stroke!

Why? Because cardiovascular disease is more than simply a high cholesterol issue! It’s a more nuanced relationship between inflammation, metabolic dysfunction, particle size, and a complex interplay of factors that a basic lipid panel doesn’t capture.

Your heart needs a more sophisticated strategy.

The Five Markers That Matter More Than Cholesterol

1. LDL Particle Number and Size (Not Just LDL-C)

Here’s something most people don’t know: LDL cholesterol is not one thing, and not all LDL cholesterol is created equal.

Standard cholesterol tests measure the amount of cholesterol carried by different LDL particles. But the cholesterol content of LDL particles is variable, causing frequent discrepancies between concentrations of LDL cholesterol and LDL particle number.

Think of it this way: You could have the same amount of cholesterol carried by many small particles or fewer large particles. And it turns out, that distinction matters enormously.

Larger number of LDL particles and smaller LDL particle size are associated with increased cardiovascular risk. Smaller LDL particles can become lodged in the arteries more easily, while the larger LDL particles appear to be less dangerous (2).

What you need to know: Ask your doctor about testing for LDL particle number (LDL-P) or Apolipoprotein B (ApoB), which gives you a direct count of atherogenic particles. This provides far more predictive information than standard LDL-C alone.

2. Inflammation Markers (Especially hs-CRP)

Remember how I said cardiovascular disease is about more than cholesterol? Inflammation is the other half of that story.

Residual inflammation, measured with high-sensitivity C-reactive protein (hs-CRP) remains strongly predictive of recurrent events, even in statin-treated patients (3).

Every step of atherogenesis, from the development of endothelial cell dysfunction to foam cell formation, plaque formation and progression, and ultimately plaque rupture, is driven by the cytokines, interleukins, and other drivers of the inflammation CITE.

In other words: Chronic inflammation is what drives plaque accumulation in your arteries, independent of your cholesterol levels.

What you need to know: Request an hs-CRP test. Levels below 1 mg/L are optimal; above 3 mg/L indicates high risk. If your hs-CRP is elevated, it’s a signal that you need to address the inflammatory burden in your body. This can be done via diet, exercise, stress management, sleep hygiene, and sometimes targeted supplementation.

3. Triglyceride-to-HDL Ratio

This might be the single most underutilized marker in conventional medicine, and it’s a travesty.

The triglyceride/high-density lipoprotein cholesterol (TG/HDL-C) ratio has been proposed as a novel biomarker associated with metabolic syndrome and cardiovascular disease (4).

Why is this ratio so powerful? Because it reveals insulin resistance and metabolic dysfunction—often years before you’d be diagnosed with prediabetes or diabetes.

A high triglyceride to HDL ratio indicates increased cardiovascular disease risk and metabolic dysfunction. While there is no official standard of optimal, ratios above 2.0 suggest early stages of insulin resistance, while optimal levels are below 1.0.

What you need to know: Calculate your TG/HDL ratio by dividing your triglyceride level by your HDL level (using the same units). Aim for below 2.0, ideally below 1.0. If your ratio is elevated, it’s a red flag that your metabolism needs attention—regardless of what your LDL number says.

4. HDL Function (Not Just HDL Number)

For years, we’ve called HDL the “good cholesterol” and assumed more is always better. But recent research has complicated that picture considerably.

Smaller, denser LDL particles and dysfunctional HDL may contribute more to atherosclerosis and cardiovascular risk than traditional lipid measures indicate. 

Yes, HDL can actually become dysfunctional, losing its protective, anti-inflammatory properties and may even become pro-inflammatory. This stems from a foundation of acute or chronic systemic inflammation (infection, atherosclerosis, diabetes, chronic kidney disease, autoimmune disease). In a state of chronic inflammation, HDL particles are structurally remodeled (protein and lipid changes), thus losing protective proteins and gaining acute‑phase or oxidized components that can become problematic (5).

What you need to know: While HDL function testing isn’t yet widely available, you can infer HDL quality by looking at your overall metabolic health. High triglycerides, elevated blood sugar, chronic inflammation, and abdominal obesity all suggest your HDL may not be functioning optimally—even if the number looks good.

5. Metabolic Health Markers (Blood Sugar, Insulin, A1C)

One common connection most people miss: Your blood sugar control directly impacts your cardiovascular risk.

 Population and clinical trial data suggest that maintaining near‑normal glucose over time (“time in target range”) is associated with substantially lower CVD and mortality. Chronically high glucose levels promote oxidative stress, inflammation, endothelial dysfunction, and accelerated atherosclerosis. (6) Those with diabetes or metabolic syndrome who work to keep glucose levels within near normal ranges benefit from lower risk of cardiovascular events than those who do not, showing that even if you’ve been diagnosed, there is still much that can be done to reduce the risk of complications from metabolic disease. (7)

Elevated blood sugar, insulin resistance, and metabolic syndrome create the perfect storm: They increase inflammation, shift your LDL particles to the smaller, more dangerous type, reduce HDL function, and elevate triglycerides. Taking steps to get these numbers in line through diet, movement, stress management and/or medication can improve your overall life expectancy and quality of life years. 

What you need to know: Ask for fasting glucose, fasting insulin, and Hemoglobin A1C. Optimal fasting glucose is below 90 mg/dL, fasting insulin below 5 μIU/mL, and A1C below 5.3%. If these numbers are creeping up—even if you’re not “diabetic”—your heart is already feeling the effects.

What Women Need to Know: The Critical Gender Differences

If you’re a woman reading this, you need to understand that cardiovascular disease presents differently in you than in men. 

Heart disease is the leading cause of death for women in the United States and can affect women at any age. In 2023, it was responsible for the deaths of 304,970 women—or about 1 in every 5 female deaths (CDC)

Yet only about half (56%) of US women recognize that heart disease is their number 1 killer!

Women Experience Different Symptoms

Women are more likely than men to have symptoms that may seem unrelated to a heart attack, such as nausea and brief pain in the neck or back. While chest pain is still the most common symptom, women report additional, potentially gender-related, non-specific symptoms, such as fatigue and sleep disturbance.

These atypical presentations mean women are often misdiagnosed or have their symptoms dismissed as anxiety. The presentation may confound the diagnosis, making dismissal of these symptoms as non-cardiac all the more perilous (8).

Women Face Unique Risk Factors

Several cardiovascular risk factors either uniquely affect women or have a more significant impact:

Pregnancy complications: High blood pressure or diabetes during pregnancy can increase women’s long-term risk of high blood pressure and diabetes. These conditions also make women more likely to get heart disease.

Menopause: After menopause, women are at a higher risk of coronary artery disease because of hormonal changes. Transition to postmenopausal status is associated with a worsening coronary heart disease risk profile in women, conveying the same degree of cardiovascular risk as being male (10).

Diabetes has a greater impact: A meta-analysis of 37 studies and almost 450,000 patients revealed a 50% greater relative risk of fatal CHD in women with diabetes compared to men with the disease (9).

Coronary microvascular disease: Women are more likely to have heart disease in the tiny arteries of the heart, called coronary microvascular disease. This can make the disease harder to identify and cause delays in treatment. (10)

Women Are Less Likely to Get Proper Care

The disparities don’t end with symptoms and risk factors. Healthcare providers may be less likely to refer women for diagnostic tests for coronary heart disease. When women go to the hospital for heart-related symptoms, they may be more likely than men to experience delays in receiving diagnostic testing (11).

What women must do: It is crucial that we all advocate fiercely for comprehensive testing given the existing circumstances of these disparities, plus the never-ending strain on the medical system as a whole, which is leading to worse patient outcomes for everyone. Know your unique risk factors (pregnancy history, menopause status, autoimmune conditions). Recognize that fatigue, sleep disturbances, and upper back pain can be cardiac symptoms—not just anxiety or stress. Don’t accept dismissal of your symptoms. See another doctor if needed and advocate for your health. 

Why This Matters for You

If your doctor is only looking at total cholesterol and LDL, you’re getting an incomplete picture.

You might have:

• “Normal” LDL but high LDL particle number
• “Good” HDL that’s actually dysfunctional
• Low-grade inflammation silently driving plaque formation
• Insulin resistance showing up in your TG/HDL ratio
• Metabolic dysfunction that won’t show up until it’s advanced

None of these show up on a basic lipid panel.

What to Do Next

1. Request comprehensive testing. Ask your doctor for: LDL-P or ApoB, hs-CRP, a full lipid panel (including triglycerides and HDL), fasting glucose, fasting insulin, and Hemoglobin A1C.
2. Calculate your TG/HDL ratio. If it’s above 2.0, prioritize strategies to improve insulin sensitivity: reduce refined carbohydrates, increase protein and healthy fats, strength train, improve sleep quality, and manage stress.
3. Address inflammation. Focus on anti-inflammatory nutrition (omega-3 fatty acids, polyphenols, fiber), regular movement, stress reduction, and quality sleep. These aren’t “soft” interventions—they directly impact your hs-CRP and cardiovascular risk.
4. Think metabolically, not just numerically. Cardiovascular health isn’t about hitting arbitrary cholesterol targets. It’s about optimizing your entire metabolic system: insulin sensitivity, inflammation control, blood sugar regulation, and lipid particle quality.
5. Work with a provider who gets it. If your doctor dismisses these concerns or says “your cholesterol is fine” without looking at the complete picture, consider finding a functional medicine practitioner or lipidologist who understands advanced lipid testing.

Evidence-Based Supplement Support

While nutrition and lifestyle form the foundation of cardiovascular health, certain supplements have robust research backing their role in reducing heart disease risk. These aren’t magic pills—they work alongside the strategies we’ve already discussed, not instead of them.

There are several essential nutrients – magnesium, omega-3 fatty acids, and folate specifically – which are shown to reduce the risk of heart disease. Of these, Omega-3s are the only which which show impact in supplement form. The other two nutrients show efficacy when consumed through diet, not supplementation. Given the prevalence of inadequate intake of these two nutrients in the general population, I always recommend looking at the food one eats over supplementation as the foundation of a health care plan (I imagine you do as well, otherwise you would not be reading this!) That said, these two supplements show promise and are ones I often recommend to my clients concerned with heart health:

1. Omega-3 Fatty Acids (EPA/DHA)

This is the supplement with the most compelling cardiovascular data, particularly for reducing inflammation and triglycerides. In my opinion, it is a non-negotiable if you do not eat cold-water fish at least three times a week.

Omega-3 fatty acids reduce cardiovascular mortality and improved cardiovascular health, with cardiovascular risk reduction more notable with EPA monotherapy over a combined supplement containing EPA+DHA (12).

Those with existing heart disease appear to benefit more than the general population with regards to cardiovascular disease risk, but Omega-3s have such great benefit overall to reduce inflammation and protect brain health that they are an essential fat I feel everyone needs to be mindful of. You can read more about Omega-3 fats and health here. 

Recommended dosage: 1-2 grams combined EPA/DHA daily from high-quality fish oil daily, or a serving of cold-water fish like salmon, herring, trout, or mackerel 3-4 times weekly.

Quality matters: Look for third-party tested products (IFOS or USP certified) to ensure purity and potency. Triglyceride form is generally better absorbed than ethyl ester form. A reliable source of Omega-3s is found at the end of this post.

Important safety note: In high doses, both prescription omega-3s and fish oil supplements can increase the risk of atrial fibrillation, and also lead to an increased risk of bleeding. If you’re on blood thinners or have a bleeding disorder, work with your provider on appropriate dosing.

2. Coenzyme Q10 (CoQ10)

CoQ10 is essential for energy production in every cell, particularly in the heart. It’s also a powerful antioxidant that protects against oxidative stress—a key driver of cardiovascular disease.

The research here is particularly strong for those with heart failure: Robust evidence demonstrates that CoQ10 supplementation can improve functional capacity, ejection fraction, and reduce major cardiovascular events in heart failure with reduced ejection fraction (13)

In a small Swedish study on elders there was a greater than 50% reduction in cardiovascular mortality in the treatment group versus placebo group taking 200mg CoQ10 along with selenium daily (14). While the study itself was 4 years long, the benefits of supplementation persisted for over a decade! This is one of those studies which I would love to see done with a larger population to confirm findings. (14)

Recommended dosage: 100-300mg daily

Best form: Ubiquinol (the reduced, active form) is more bioavailable than ubiquinone, especially for those over 40.

Critical for statin users: Statins deplete CoQ10 as a side effect of blocking the same metabolic pathway. If you’re experiencing muscle pain, fatigue, or weakness on statins, CoQ10 supplementation may help. Discuss this with your provider before making changes.

A Word on Individualization

These supplements have solid evidence, but that doesn’t mean everyone needs both, or that these are the only ones that might benefit you.

Your specific supplement protocol should be based on:

• Your lab results (What are your inflammatory markers? Triglycerides? Blood sugar?)
• Your health history (Are you on statins? Do you have heart failure? Diabetes?)
• Your dietary intake (Are you eating fatty fish 2-3x/week? Getting adequate magnesium from food?)
• Your unique biochemistry and genetics

Work with a functional medicine practitioner or qualified nutritionist who can help you identify which supplements make sense for your cardiovascular profile—not just what’s trending on social media.

Quality is non-negotiable: Not all supplements are created equal. Look for third-party testing (USP, NSF, or ConsumerLab), avoid proprietary blends that don’t disclose dosages, and be wary of bargain-basement pricing as this suggests low-quality ingredients were used in formulation.

Major retailers like Amazon often source supplements from third-party resellers, which makes it nearly impossible to verify authenticity, freshness, or proper handling. They openly admit counterfeit supplements are pervasive and struggle to keep that under control. This is why I exclusively recommend Fullscript. The Fullscript team invests over $10 million annually in quality control—vetting brands and testing individual products to guarantee safety and efficacy. You’ll get 20-35% off retail prices, access to my curated recommendations, free shipping on orders over $50, and fast delivery. When you’re investing in your health, source matters.

Order with confidence through Fullscript, and you’ll also have access to all my favorite supplements, as well as specific protocols depending upon phase of training or life!

The Bottom Line

Heart disease is the leading cause of death for men, women, and people of most racial and ethnic groups and is still the leading cause of death for people over 40—but it doesn’t have to be.

The tools exist to assess your risk far more accurately than traditional cholesterol screening. The interventions exist to address the root causes—inflammation, insulin resistance, metabolic dysfunction—rather than just suppressing one number with medication.

You just need to know what to ask for!

This Heart Health month, demand the complete picture. Your health is worth a more nuanced conversation.

Your heart—and your future self—will thank you.
