Cardiovascular disease and heart disease: What’s the difference?

Are cardiovascular disease and heart disease the same thing? In short, no - cardiovascular disease is the general term for conditions affecting the heart (cardio) or blood vessels (vascular) and covers all heart and circulatory diseases, including: 2

  • Heart disease 
  • Angina
  • Heart attack 
  • Congenital heart disease
  • Hypertension
  • Stroke
  • Vascular dementia

Heart disease is another broad term used to describe a range of disorders affecting your heart, and these include: 2

  • Coronary heart disease
  • Heart arrhythmia
  • Congenital heart disease

There’s a strong correlation between both cardiovascular disease and diabetes and heart disease and diabetes. In both, blood vessels narrow and the amount of oxygen-rich blood reaching the body’s vital organs is severely reduced. 3

The blood pressure rises, and your heart must work harder to move blood around the body. Over time, this can cause lasting damage to the heart, resulting in cardiovascular disease. 3

Living with type 2 diabetes?

Here's how you can reduce the risk of heart problems through food and lifestyle changes

What is the correlation between type 2 diabetes and cardiovascular disease?

Both type 1 and type 2 diabetes have established risk factors for cardiovascular disease. 4

You’ll likely already be familiar with the symptoms of type 2 diabetes, and this knowledge will come in handy when exploring the correlation between type 2 diabetes and cardiovascular disease. 

As a quick refresher, note that type 2 diabetes causes high glucose levels in the bloodstream. This can quickly lead to the damaging of blood vessel walls, an increase in fatty materials and the reduction of blood flow. This kind of build-up can starve the heart of oxygen and nutrition, potentially resulting in severe heart conditions, strokes, and high blood pressure.

The most common symptoms of cardiovascular diseases and something you should look out for as a patient with type 2 diabetes, include: 6

  • Chest pain
  • Pain, weakness, or numb legs and/or arms
  • Breathlessness
  • Very fast or slow heartbeat, or palpitations
  • Feeling dizzy/ lightheaded or faint
  • Fatigue
  • Swollen limbs

Diabetes and strokes 

Can a stroke cause diabetes? While some people are only diagnosed with diabetes after they’ve had a stroke, it’s more common for diabetes to cause a stroke (or a diabetes mini stroke) as high blood pressure levels continue to damage blood vessel walls. 8 Diabetes stroke symptoms include: 

  • Weakness in your face or arms 
  • Slurred speech 
  • Sudden blurred vision 
  • Trouble swallowing 

Although post-stroke patients with diabetes are predisposed to a slower recovery of function, diabetes stroke recovery is possible. A successful recovery requires the brain to remap sensorimotor functions within the brain network. 9

Preventing cardiovascular disease & reducing risk

When it comes to managing cardiovascular disease, preventative efforts are key. Patients with type 2 diabetes should turn to medication, lifestyle changes and risk factor interventions to reduce their risk of cardiovascular disease. Note, every condition is different and reducing the risk of cardiovascular disease will require a different approach from person to person.  

If you have any type of diabetes (type 1, type 2, gestational, adolescent) you should pay close attention to your lifestyle habits. Lifestyle factors that alleviate narrow or clogged blood vessels, and increase the risk of cardiovascular disease, include:

High cholesterol

Clinical evidence shows that a cholesterol level reduction may lower the mortality rate from cardiovascular disease.

Eating unhealthy food

A nutritionally limited or poor diet can lead to high blood pressure. Try to reduce your daily sodium intake.


Smoking is a significant risk factor for cardiovascular disease. Tobacco is known to damage and narrow blood vessels.

Drinking too much alcohol

Studies have indicated a positive correlation between cardiovascular disease and alcohol consumption above recommended limits.


There is also a positive correlation between the reduction of body fat and insulin sensitivity. Addressing weight loss (physical activity is one of many options) is key to achieving steady blood sugar levels. 

how to prevent CVD

Exercising more, eating a balanced diet to lose weight, and cutting out bad habits like excessive drinking and smoking are all great ways to reduce your risk of cardiovascular disease. 

While lifestyle changes are important for reducing the risk of cardiovascular disease, it’s also imperative that you continue to monitor blood sugar level carefully and manage your medication.

Type 2 diabetes is a complex chronic disease that occurs when the body cannot make enough insulin. In contrast, type 1 diabetes is a lifelong disease that affects the body’s ability to convert glucose from food into energy.  Read more about diabetes in general here.
