Love Your Heart: Preventing Heart Disease

Heart disease remains one of the leading health challenges facing Canadians today—but the good news is that many risk factors can be prevented or improved with the right knowledge and support. From understanding key health numbers to making simple lifestyle changes, here’s how you can take meaningful steps to protect your heart.

1. Heart Health: Quick Facts

Heart disease is more common than most people realize. Here are a few important insights:

  • Over 2.6 million Canadians are living with diagnosed heart disease.
  • Heart disease is Canada’s second leading cause of death, after cancer.
  • 9 in 10 Canadians have at least one risk factor for developing heart disease.
  • Men are typically diagnosed 10 years earlier than women.
  • Many risk factors are preventable, and early screening can significantly reduce your risk.

2. Know Your Numbers: Key Indicators for Heart Health

A. Know Your Blood Pressure
High blood pressure is the most common preventable risk factor for heart disease and is linked to nearly half of cases worldwide. Hypertension Canada recommends:1. Use a validated automated blood pressure monitor

  • Only 45% of online‑sold monitors are validated for accuracy.
  • 90% of monitors sold in community pharmacies, including London Drugs, meet Hypertension Canada’s validation standards.
  • Your pharmacist can recommend the right device and teach you proper technique.

2. Know your blood pressure target

  • Most adults should aim for below 130/80 mmHg (2025 Hypertension Canada Guidelines).
  • Your target may vary based on age, health conditions, and your doctor’s recommendations.
  • If your readings are consistently high, your healthcare provider may prescribe medications to help manage it.

B. Know Your Sugars (A1C)Your Hemoglobin A1C test shows your average blood sugar over the past 2–3 months.

Targets:

  • A1C below 6.0% for people without diabetes
  • A1C 7.0% or lower for most people with diabetes

People with diabetes are 2–4 times more likely to develop heart disease.

Screening:

  • Adults over 40 should have glucose screening every 3 years.
  • Those at higher risk may need more frequent tests.

C. Know Your Cholesterol

Cholesterol is essential for many body functions, but too much can contribute to plaque buildup and block blood flow to the heart and brain.

  • Two types: LDL (“bad”) and HDL (“good”)
  • Chronic high cholesterol increases the risk of heart attack and stroke
  • Regular screening begins at age 40, or earlier if you’re high-risk

If medication is needed, your provider may prescribe treatments that reduce cholesterol production or absorption.

3. Know Your Risks: Steps to Lower Heart Disease Risk

Some risk factors can’t be changed, like age or family history—but many can. Here’s what you can focus on:

✓ Eat a balanced, heart‑healthy diet

  • Follow Canada’s Food Guide
  • Diets like Mediterranean or DASH help lower heart disease risk

✓ Move your body regularly

  • Aim for 150 minutes of activity per week
  • Include muscle‑strengthening exercises
  • Reduce long periods of sitting

✓ Maintain a healthy weight

Being over‑ or under‑weight increases heart disease risk. Balanced nutrition and movement help you stay within a healthy range.

✓ Prioritize sleep

  • Poor sleep affects blood pressure, weight, and blood sugar.
  • Aim for 7–9 hours nightly.

Tips:

  • Keep your room cool, dark, quiet
  • Maintain a consistent schedule
  • Avoid screens before bed

✓ Quit smoking

Smoking damages blood vessels and accelerates plaque buildup. Your London Drugs pharmacist can:

  • Help identify triggers
  • Build a personalized quit plan
  • Provide nicotine replacement and other treatments
  • Offer ongoing support

✓ Limit alcohol

Health Canada’s guidance states:

  • No amount of alcohol is risk‑free
  • More than 3 drinks/week increases cancer risk
  • More than 7 drinks/week increases heart disease and stroke risk

Reducing intake lowers your risk.

The Facts About Cholesterol

Cholesterol is an important substance in our bodies that, for the most part, occurs naturally. It helps our bodies make hormones, process vitamin D, build cells and create substances that help us digest food. Cholesterol can become dangerous, though, when the levels in our blood stream get too high.
Most of the cholesterol in our bodies—about 80%—is made by our liver. The other 20% comes from the foods we eat. A person can’t tell if his or her cholesterol levels are too high, as there aren’t any noticeable symptoms. To determine your cholesterol levels you need to have a blood test done by your doctor involving a tiny sample of blood.
The test will analyze the two main components of cholesterol—low-density lipoprotein (LDL) and high-density lipoprotein (HDL).
LDL is sometimes referred to as “bad” cholesterol, because at high levels it builds up and can block our arteries, preventing blood moving freely through our bodies. HDL is usually called “good” cholesterol, because its job is to carry excess cholesterol from other parts of our bodies, including the arteries, back to the liver. Not only does the liver produce cholesterol, it also removes it from our bodies.
Your doctor may also assess your triglyceride and C-reactive protein levels. These are other indicators found in your blood test that could signal an increased risk of heart attack or stroke.

Lowering Cholesterol

The first step is to make a lifestyle change, and a big part of lifestyle is eating a healthier diet. Here are some things you should reduce or avoid to maintain healthy cholesterol levels:
  • Saturated fats—These are found in animal-based foods such as meat and dairy products, and in some plant foods such as coconut oil, palm oil, and cocoa butter. Avoid or limit deli meats. Choose lean cuts of meat, or replace with fish and legumes (lentils, beans) instead.
  • Trans fats—These are a form of man-made fat that is created during a process called hydrogenation. This is where liquid oils are turned into solid fat (such as some margarines.) While technically unsaturated, these facts act like saturated fats and raise blood levels of LDL (“bad”) cholesterol. Choose oils high in mono-and polyunsaturated fats such as canola, corn, or soya oil. Use in moderation.
  • Avoid dairy products with high milk fat—choose 1% MF (milk fat) or cheeses with 15% MF or lower.
There are things you can add to or change in your diet which help the body eliminate excess blood cholesterol.
  • Soluble fibre—This is found in oat bran, fruits, and vegetables.
  • Unsaturated fats—These are found in vegetable oils, nuts, seeds, and fatty fish.
  • Cooking—More often than not, opt to broil, bake, poach, or even microwave food instead of frying.

Other tips to beat “bad” cholesterol

Keeping active and maintaining a healthy body weight will also help reduce cholesterol levels. And finally, quit smoking. It’s been found that tobacco reduces your level of HDL, “good” cholesterol, and raises your total blood cholesterol levels—which makes the perfect combination for increasing your total risk of having a heart attack.
If your doctor feels you need to be on cholesterol-lowering medication, it’s important to take it exactly as directed. For more information on cholesterol, or advice on making different lifestyle choices, come by the pharmacy and ask your London Drugs pharmacist.
