The Long View of Prevention: Cardiometabolic Risk
When people think about cardiovascular disease, they often think about cholesterol.
High cholesterol. Low cholesterol. Good cholesterol. Bad cholesterol.
Cholesterol matters, but the story is more nuanced.
Cardiovascular risk is influenced by genetics, metabolism, inflammation, lifestyle, and time. Two people with the same LDL cholesterol level may have very different long-term risk profiles.
At Signal Health, my approach is not simply to treat a laboratory value. The goal is to better understand an individual’s cardiovascular risk and focus on interventions most likely to improve long-term outcomes.
Looking Beneath the Surface
Traditional cholesterol testing provides useful information, but it doesn’t always tell the full story.
When appropriate, I may recommend additional testing to better understand cardiovascular risk, including:
Apolipoprotein B (ApoB)
Lipoprotein(a)
High-sensitivity C-reactive protein (hsCRP)
Metabolic markers related to insulin resistance and glucose regulation
These tests are not necessary for everyone. However, in the right context, they can provide valuable insight into risk that may not be apparent from a standard lipid panel alone.
The objective is not to collect more data for its own sake. It’s to obtain information that may meaningfully influence decisions about prevention and treatment.
The Importance of Metabolic Health
Cardiovascular disease is often viewed through the lens of cholesterol alone.
In reality, metabolic health plays a central role.
Excess visceral fat, insulin resistance, elevated blood sugar, poor sleep, physical inactivity, and hypertension frequently travel together and can substantially influence long-term cardiovascular risk.
For many patients, improving metabolic health may be as important as improving lipid levels.
This is one reason why conversations about nutrition, body composition, sleep, physical activity, and stress resilience often become part of cardiovascular prevention.
The goal is not simply to lower a number on a laboratory report. The goal is to improve the overall environment in which cardiovascular disease develops.
When Imaging Adds Clarity
Risk calculators can be helpful, but they have limitations.
Sometimes the most useful question is straightforward:
Is there evidence of disease already present?
In selected patients, imaging can help answer that question.
Coronary artery calcium (CAC) scoring is one of the most useful tools available for refining cardiovascular risk. By measuring calcified plaque within the coronary arteries, CAC testing can provide information beyond traditional risk factors alone.
In certain situations, coronary CT angiography (CCTA) may provide additional insight.
These studies are not appropriate for everyone, nor should they be ordered routinely. When used thoughtfully, however, they can help guide decisions and avoid both undertreatment and overtreatment.
Individualized Treatment
Not every patient requires medication.
Not every patient should avoid medication.
The right approach depends on the individual.
For some, lifestyle interventions may be sufficient. For others, medication meaningfully reduces risk and becomes an important part of a comprehensive prevention strategy.
When medication is indicated, treatment should be tailored to the patient rather than forcing the patient to fit the treatment.
This includes working through challenges such as statin intolerance, selecting alternative therapies when appropriate, and balancing benefits, risks, and patient preferences.
The goal is not perfect laboratory values. The goal is reducing the likelihood of heart attack, stroke, and other cardiovascular events over the course of a lifetime.
Signal Over Noise
Cardiovascular prevention is often presented as a series of isolated decisions: a cholesterol medication, a diet, a laboratory result, or a scan.
In reality, cardiovascular health is shaped by the cumulative effect of many factors over many years.
The most meaningful progress rarely comes from a single breakthrough. More often, it comes from understanding risk clearly, focusing on the factors that matter most, and making thoughtful adjustments over time.
Good prevention is not about chasing every possible test or treatment.
It’s about identifying the signal among the noise—and acting on it early enough to change the future.
