6 Evidence-Based Ways to Strengthen Your Heart Health

Heart disease remains the leading cause of death in the United States, responsible for roughly 1 in 5 deaths each year. Yet much of that risk is modifiable. Cardiovascular disease develops gradually, often over decades, shaped by lipid metabolism, inflammation, blood sugar regulation, and lifestyle factors that compound over time. The encouraging news: targeted, consistent changes to diet, movement, sleep, and lab monitoring can meaningfully shift your cardiovascular risk profile, frequently years before any symptoms appear.

Below are six science-backed strategies to support long-term heart health, along with the lab markers worth tracking to understand your individual risk.

1. Prioritize Protein & Fiber

Stable blood sugar, lower systemic inflammation, and healthier lipid levels all start with what's on your plate. Diets adequate in both protein and fiber support healthy triglyceride levels, improve insulin sensitivity, and help regulate cholesterol metabolism. Learn how to build a balanced plate here.

Fiber-rich foods: lentils, chickpeas, chia seeds, flaxseed, avocado, berries, apples, and cruciferous vegetables.

Protein-rich foods: wild-caught fish, organic grass-fed beef, pasture-raised poultry, organic tofu, and omega-3-rich eggs.

2. Move with Purpose

Exercise affects cardiovascular risk through multiple pathways. Strength training has been shown to raise HDL cholesterol (the "good" cholesterol that helps clear excess cholesterol from the bloodstream), while walking supports lipid metabolism and insulin sensitivity. Beyond structured workouts, staying active throughout the day — taking the stairs, walking after meals, stretching between calls — adds up. Small, consistent movement habits compound into meaningful cardiovascular benefits over time. We love Evlo Fitness. 

3. Focus on Healthy Fats & Omega-3s

Not all fats affect the cardiovascular system equally. Unsaturated fats and omega-3 fatty acids help calm inflammation and support balanced cholesterol levels, while reducing intake of processed seed oils and trans fats.

Omega-3-rich foods: salmon, sardines, mackerel, trout, herring, mussels, oysters, and roe.

Heart-healthy fats: extra-virgin olive oil, avocado, seeds (flax, chia, hemp), raw nuts, and algae-based omega-3 sources.

4. Protect Your Sleep

Sleep is an underappreciated pillar of cardiovascular health. Poor sleep quality and insufficient sleep duration disrupt lipid metabolism and are associated with elevated cardiovascular risk. Aim for 7–9 hours of high-quality sleep per night, and treat sleep as a non-negotiable component of any heart-health strategy. Check out our top tips for a restful night sleep here. 

5. Check Your Calcium Score

A coronary artery calcium (CAC) scan measures existing plaque buildup in the coronary arteries and offers a direct window into cardiovascular risk that standard cholesterol panels can miss. If LDL is elevated but CAC is zero, your short-term risk may be lower than the LDL number alone suggests. However, if both ApoB and CAC are elevated, it signals a clearer need for intervention. This test adds important context that a lipid panel alone cannot provide.

6. Expand Your Lab Work

Standard cholesterol panels only tell part of the story. To get a complete picture of cardiovascular risk, consider discussing these additional markers with your care team:

• ApoB — a key marker of cardiovascular risk, reflecting the total number of atherogenic (plaque-forming) particles in the blood
• Lp(a) — a genetic risk factor often missed in standard testing, largely unaffected by diet or lifestyle
• hs-CRP — a marker of systemic inflammation associated with cardiovascular events
• Fasting insulin — an early indicator of metabolic dysfunction, which often precedes cardiovascular disease
• Omega-3 Index — measures omega-3 fatty acid levels in red blood cells; low levels correlate with higher cardiovascular risk
• Homocysteine — an amino acid linked to arterial damage when elevated

Why Proactive Heart Health Monitoring Matters

Cardiovascular disease is, in large part, a condition of accumulation. Risk factors like elevated ApoB, chronic inflammation, and insulin resistance can be present and progressing for years before they show up as a diagnosis or an event. Waiting for symptoms means waiting until the disease has already had time to take hold. The more effective approach is proactive: tracking trends in your labs and risk markers over time, rather than relying on a single annual snapshot, so that changes can be caught and addressed while they're still easy to manage.

How The Lanby Supports Your Heart Health

This is where comprehensive primary care makes the difference. At The Lanby, heart health is one of the four foundational pillars we monitor as part of every member's care, alongside metabolic, hormone, and nutrient health. Your Care Team looks beyond a standard cholesterol panel, incorporating expanded lab work like ApoB, Lp(a), hs-CRP, and fasting insulin, along with your symptoms, history, lifestyle, and goals, to build a complete picture of your cardiovascular risk.

Rather than waiting for a problem to surface, The Lanby's model of dynamic, connected care is designed to catch what's changing early, before it becomes a diagnosis. If you're ready to take a proactive approach to your heart health, book a complimentary consult call to learn how The Lanby's Care Team can help you build a personalized, long-term plan for your cardiovascular health.
