Heart Health: The Numbers Men Should Know

You probably know your phone number.

You may know your bank balance, your vehicle mileage, your golf score, the size of the engine in your truck, or exactly how much lumber you need for the next project.

But do you know your blood pressure?

Your cholesterol?

Your blood sugar?

Your waist circumference?

You may know your bank balance, your vehicle mileage, your golf score, the size of the engine in your truck, or exactly how much lumber you need for the next project.
But do you know your blood pressure?
Your cholesterol?
Your blood sugar?
Your waist circumference?
Some of the most important information about your health can be expressed in surprisingly small numbers.
And unlike many physical symptoms, cardiovascular risk can develop quietly.
High blood pressure, for example, often produces no obvious warning symptoms. That is one reason knowing your numbers matters.
## Your Heart Doesn't Work Alone
Heart health isn't determined by one measurement.
Blood pressure, cholesterol, blood glucose, body composition, activity, smoking, sleep, family history, age and other health conditions can all contribute to someone's overall cardiovascular risk.
One number therefore shouldn't be viewed in isolation.
Think of them as pieces of the same puzzle.
## 1. Blood Pressure
Blood pressure is written as two numbers, such as 120/80 mmHg.
The first number—systolic pressure—represents the pressure in the arteries when the heart contracts.
The second—diastolic pressure—represents the pressure while the heart relaxes between beats.
High blood pressure is particularly important because it can damage blood vessels over time and is a major risk factor for both heart disease and stroke.
## Don't Wait Until You “Feel” High Blood Pressure
You cannot reliably determine your blood pressure by how you feel.
That makes actually measuring it important.
If your readings are repeatedly elevated, don't diagnose yourself from one reading or ignore a pattern. Record the results and discuss them with your healthcare professional.
Your appropriate blood-pressure target may depend on your health history and other cardiovascular risk factors.
## 2. Cholesterol
Cholesterol isn't simply one number either.
A lipid test can include several measurements, including:
LDL cholesterol — often the major cholesterol measurement considered when assessing and managing cardiovascular risk.
HDL cholesterol — involved in transporting cholesterol away from tissues.
Triglycerides — another type of fat circulating in the blood.
Heart & Stroke Canada identifies high blood cholesterol as one of the major controllable risk factors for heart disease.
Rather than memorizing one universal “good cholesterol number,” ask your healthcare professional:
“What should my cholesterol targets be based on my overall cardiovascular risk?”
That question matters because the appropriate approach can differ considerably between people.
## 3. Blood Glucose and A1C
Blood sugar belongs in a conversation about heart health too.
Diabetes can affect blood vessels and is associated with increased cardiovascular risk.
Two numbers you may hear are:
Fasting plasma glucose — blood glucose measured after fasting.
A1C — a laboratory measurement reflecting average blood glucose over approximately the previous two to three months.
Under current Diabetes Canada diagnostic criteria, fasting plasma glucose of 7.0 mmol/L or higher or an A1C of 6.5% or higher can meet laboratory criteria for diabetes in adults in appropriate circumstances. In someone without symptoms, an abnormal result generally requires confirmation rather than self-diagnosis from a single result.
Diabetes Canada identifies an A1C of 6.0–6.4% as within its prediabetes criteria.
These are diagnostic reference points, not personal treatment targets.
## 4. Waist Circumference
This one requires no laboratory.
Where the body stores fat can matter in addition to body weight alone.
Waist circumference provides one simple way of estimating abdominal adiposity.
Canadian metabolic-syndrome criteria use a waist circumference of 102 cm (40 inches) or greater for men in the Canada/USA population category as one risk threshold. Importantly, Diabetes Canada also lists lower population-specific cut-offs for some ethnic groups, so 102 cm should not be treated as a universal number for every man.
That distinction is important.
A waist measurement is not a judgment about appearance.
It is another piece of health information.

<h2>Know Your Numbers</h2>
<p>Consider keeping a simple personal health record with your most recent:</p>
<p><strong>Blood Pressure</strong><br>____ / ____ mmHg</p>
<p><strong>LDL Cholesterol</strong><br>________ mmol/L</p>
<p><strong>HDL Cholesterol</strong><br>________ mmol/L</p>
<p><strong>Triglycerides</strong><br>________ mmol/L</p>
<p><strong>Fasting Blood Glucose</strong><br>________ mmol/L</p>
<p><strong>A1C</strong><br>________ %</p>
<p><strong>Waist Circumference</strong><br>________ cm / ________ inches</p>
<p><strong>Date Checked:</strong><br>________________________________________</p>
<p><strong>Then take the most important step:</strong><br>Ask your healthcare professional what these numbers mean for you.</p>
</div>## A Number Is Information, Not a Grade
This may be the most important part of the article.
A blood test isn't a report card.
Neither is a blood-pressure reading or waist measurement.
Finding out that a number is outside the recommended range doesn't mean you have failed.
It means you have information you didn't have before.
And information gives you an opportunity to act.
## The Numbers Can Change Before You Feel Different
This is one reason routine health checks matter.
Someone can feel perfectly well while blood pressure, cholesterol or glucose levels are changing.
Conversely, feeling tired or unwell doesn't automatically mean one of these measurements is abnormal.
Testing replaces guessing.
## What Can You Influence?
Heart health isn't about perfection.
Regular movement, nutritious eating patterns, adequate sleep, avoiding tobacco, managing health conditions, maintaining social connection and following appropriate medical treatment can all be pieces of cardiovascular health.
The goal isn't to control every variable.
It is to identify the ones you can influence—and know when professional medical care belongs in the picture.
## One Appointment Can Answer a Lot of Questions
If you haven't had a routine health assessment in some time, consider asking your healthcare professional:
What is my blood pressure?
When was my cholesterol last checked?
Should my blood glucose or A1C be tested?
What is my overall cardiovascular risk?
Based on my personal and family history, are there other tests I should consider?
Diabetes Canada currently recommends screening for type 2 diabetes using fasting plasma glucose and/or A1C at least every three years beginning at age 40, or earlier/more frequently for people at higher risk.
## The Strength of Knowing
There is something very Elemental Reset about knowing your numbers.
We cannot change what we refuse to look at.
And we don't have to fear information simply because it might tell us that something needs attention.
Sometimes health begins with a remarkably simple sentence:
“I don't know my numbers. I think it's time I did.”
Because strength isn't only about what your body can do.
It is also about taking responsibility for the body that carries you through your life.
