Protecting Your Heart: A Practical Prevention Guide for Adults in Richmond, BC

Heart disease rarely announces itself. For many adults, the first sign that something has been building for years is a symptom that sends them to emergency. The encouraging part is that much of what drives cardiovascular risk can be measured, tracked and improved long before that point. This guide walks through the main risk factors, the tests worth knowing about, and why steady follow-up with a family physician matters more than any single checkup.

Know Your Numbers: The Core Risk Factors

Cardiovascular risk is the sum of many small pressures acting on your arteries over decades. Some you cannot change, such as age, sex and a family history of early heart disease in a parent or sibling. Others are very much within reach:

• Blood pressure. High blood pressure usually causes no symptoms, which is why it is often missed. Over time it strains the heart and damages the lining of blood vessels. Canadian hypertension guidance encourages regular measurement, including home readings with a validated cuff, because clinic readings alone can be misleading.
• Cholesterol and other lipids. LDL cholesterol contributes to plaque build-up in artery walls. Results in Canada are reported in mmol/L, and what counts as "acceptable" depends on your overall risk rather than one universal cut-off.
• Blood sugar. Diabetes and prediabetes are associated with higher cardiovascular risk. A fasting glucose or an A1C test helps show where you stand.
• Smoking and vaping. Tobacco damages blood vessels and promotes clotting. Stopping at any age is linked with lower risk, and BC has provincial programs to help with cessation support.
• Weight, waist size and activity. Carrying extra weight around the abdomen is associated with higher blood pressure, unfavourable lipids and insulin resistance.
• Sleep and stress. Chronic stress, poor sleep and untreated sleep apnea are increasingly recognised as contributors worth discussing with your doctor.

None of these numbers tells the full story on its own. Their real value comes from looking at them together and watching how they change over time.

Beyond the Standard Panel: ApoB, Lp(a) and Risk Calculators

A routine lipid panel measures total cholesterol, LDL, HDL and triglycerides. In recent years, Canadian lipid guidance has also recognised a few additional markers that can sharpen the picture for some people:

• Apolipoprotein B (ApoB). Each particle that can carry cholesterol into the artery wall contains one ApoB molecule, so ApoB reflects the number of these particles. It can be especially useful when triglycerides are high or when LDL alone may underestimate risk, such as in people with diabetes or metabolic syndrome.
• Lipoprotein(a), or Lp(a). This is largely inherited and does not change much with lifestyle. Canadian guidance has suggested that many adults have it measured at least once, since a high level can shift how aggressively other risk factors are managed.
• Risk scores. Physicians in Canada commonly use validated calculators that combine age, sex, blood pressure, lipids, smoking and diabetes status to estimate a 10-year risk. That estimate helps decide whether lifestyle changes alone are reasonable or whether medication should be discussed.

These tools are not about chasing perfect lab values. They are about matching the intensity of prevention to your actual level of risk.

Coronary Artery Calcium Scoring: When It Can Help

A coronary artery calcium (CAC) score is a low-dose CT scan that looks for calcified plaque in the heart's arteries. It does not replace blood tests or a physical exam, and it is not appropriate for everyone. Where it can be helpful is in the "grey zone": adults whose calculated risk sits in the middle, or who have a strong family history, and who are unsure whether to start a cholesterol-lowering medication.

A score of zero can be reassuring in the right context, while a higher score may prompt a closer look at prevention. Because it involves radiation and can lead to further testing, the decision to do one is best made with a physician who knows your history. MMC Wellness offers access to private CT and MRI imaging; whether a calcium score is appropriate for you, and where it can be done, is a question to discuss with a physician.

Daily Habits That Support a Healthy Heart

Lifestyle is not a consolation prize for people who don't want medication. For most adults it is the foundation of prevention, and it works alongside any treatment your doctor recommends.

• Move most days. Canadian physical activity guidelines suggest about 150 minutes a week of moderate-to-vigorous aerobic activity, plus muscle-strengthening activities at least twice a week. Brisk walks along the Richmond dyke trails count.
• Eat in a pattern, not by rules. A diet rich in vegetables, fruit, whole grains, legumes, nuts, fish and plant oils, and lower in processed meats, refined starches and sugary drinks, is associated with better heart health. Canada's Food Guide offers a practical starting point.
• Watch sodium. Many packaged and restaurant foods, including sauces and soups, carry a lot of hidden salt.
• Limit alcohol. Current Canadian guidance on alcohol emphasises that less is better for health.
• Protect your sleep and find a sustainable way to manage stress, whether that is exercise, time outdoors, social connection or counselling.

Small, consistent changes tend to outlast dramatic resolutions.

Why Ongoing Care With a Family Physician Matters

A single test result is a snapshot. Prevention depends on the trend: whether your blood pressure is creeping up, whether a new medication is working, whether your A1C is moving in the right direction. That kind of follow-through is what a family physician provides. They can order and interpret tests in context, adjust treatment, watch for side effects and coordinate specialist referrals when needed.

If you do not currently have a family doctor in BC, you can register with the provincial Health Connect Registry through HealthLink BC online or by calling 8-1-1.

For people who want a more detailed baseline, a self-pay comprehensive health exam brings many of these assessments together in one visit. For those who want help keeping everything on track afterwards, our health management membership adds care coordination and value-added services on top of regular medical care. It does not replace a family doctor; it is designed to support that relationship.
