Monitoring blood sugar is only one aspect of living with diabetes. Diabetes can affect blood vessels over time and increase the likelihood of cardiovascular problems. For this reason, understanding your overall heart health and regularly reviewing important risk factors can be an important part of long-term care.
Many people feel well even when blood pressure, cholesterol or blood glucose levels are outside their recommended range. This is one reason regular health checks matter. Identifying risk factors early can give patients an opportunity to make lifestyle changes and discuss appropriate treatment with their healthcare team.
At COR Cardiology, cardiovascular care focuses on understanding the individual patient rather than looking at a single test result. When diabetes is part of a patient’s health history, a broader assessment can help identify factors that may influence future cardiovascular health.
Why Is Diabetes Important for Heart Health?
Diabetes occurs when the body has difficulty regulating blood glucose. Persistently elevated blood glucose can affect blood vessels and contribute to cardiovascular complications over time.
According to the Heart Foundation, people with diabetes are about twice as likely to develop heart disease or have a stroke compared with people without diabetes. The Heart Foundation also reports that around 30% of people with type 2 diabetes also have cardiovascular disease.
This means managing diabetes should include attention to cardiovascular risk—not simply blood glucose.
How Can Diabetes Affect the Cardiovascular System?
Over time, elevated blood glucose can contribute to changes in blood vessels. Diabetes may also occur alongside other cardiovascular risk factors, including high blood pressure, abnormal cholesterol, excess weight and physical inactivity.
When several risk factors occur together, cardiovascular risk can increase.
This is why a person with diabetes may benefit from discussing their complete cardiovascular risk profile with their healthcare professionals.
What Should Patients With Diabetes Monitor for Better Heart Health?
There is no single measurement that tells you everything about your cardiovascular health. Several factors should be considered together.
Should You Monitor Blood Glucose?
Yes. Blood glucose management is an important part of diabetes care.
Your doctor may recommend monitoring blood glucose at home and having longer-term blood glucose measurements such as HbA1c when appropriate.
The risk of complications can be decreased with effective diabetes treatment. However, cardiovascular prevention involves more than glucose control alone.
Do You Need to Regularly Check Your Blood Pressure?
Yes. Blood pressure is an important cardiovascular risk factor.
The Heart Foundation explains that diabetes and high blood pressure are closely linked, and managing both is important for reducing the risk of heart attack and stroke.
Your healthcare professional can determine your appropriate blood pressure target based on your individual circumstances.
Why Is Cholesterol Important?
Cholesterol is another important factor to monitor.
High levels of LDL cholesterol can contribute to plaque formation within arteries. Diabetes can also occur alongside abnormal cholesterol levels, making lipid assessment an important component of cardiovascular risk management.
A blood test can measure cholesterol and triglycerides, helping your doctor understand your lipid profile.
Should You Monitor Your Weight and Waist Circumference?
Weight and abdominal fat can influence metabolic and cardiovascular health.
Rather than focusing only on a number on the scales, your healthcare professional can consider your overall health, activity level, blood pressure, blood glucose, cholesterol and other risk factors.
How Does Diabetes Increase Heart Disease Risk?
Diabetes can influence cardiovascular health in several ways.
Can Blood Vessels Be Affected by High Blood Glucose?
Persistently elevated blood glucose can contribute to damage within blood vessels. Over time, this can make it easier for fatty deposits to develop within artery walls.
This process can contribute to atherosclerosis and increase the risk of coronary heart disease.
Can Diabetes Increase the Risk of High Blood Pressure?
Yes. Diabetes and high blood pressure frequently occur together. High blood pressure can place additional strain on blood vessels and the heart.
The Heart Foundation identifies diabetes and high blood pressure as important risk factors for cardiovascular disease.
Can Diabetes Affect Cholesterol?
Diabetes can be associated with an unfavourable lipid pattern, including changes in triglycerides and cholesterol. This is why a comprehensive cardiovascular assessment should consider blood lipids alongside glucose and blood pressure.
What Heart Tests Might Be Considered for Someone With Diabetes?
Not everyone with diabetes needs every cardiac test. The appropriate investigation depends on symptoms, risk factors, medical history and clinical assessment.
When Might an ECG Be Useful?
An electrocardiogram, or ECG, records the electrical activity of the heart.
It may be recommended when a patient has symptoms such as:
- Palpitations
- Chest discomfort
- Shortness of breath
- Dizziness
- Fainting
- An irregular heartbeat
An ECG is only one part of cardiovascular assessment and does not detect every type of heart problem.
When Might an Echocardiogram Be Recommended?
An echocardiogram uses ultrasound to create images of the heart.
Depending on the clinical situation, it can provide information about:
- Heart chamber structure
- Heart muscle function
- Heart valves
- Pumping function
- Certain structural abnormalities
A cardiologist determines whether an echocardiogram is appropriate based on the patient’s symptoms and clinical findings.
When Could a Stress Echocardiogram Be Considered?
A stress echocardiogram assesses how the heart performs when it is working harder.
It may be considered when a doctor needs additional information about possible coronary artery disease or symptoms that occur with exertion.
The test selected should always be based on individual clinical circumstances.
When Should Someone With Diabetes See a Cardiologist?
Not every person with diabetes automatically needs specialist cardiology care. However, discussing cardiovascular assessment with your doctor may be appropriate if you have symptoms or several cardiovascular risk factors.
What Symptoms Should Not Be Ignored?
Seek medical assessment for symptoms such as:
- Chest pain or pressure
- Unexplained shortness of breath
- Persistent palpitations
- Fainting or near-fainting
- Unusual fatigue associated with exertion
- Swelling in the legs
- Reduced exercise tolerance
Symptoms can have many causes, but some may indicate a cardiovascular problem.
If you experience severe or sudden chest pain, severe difficulty breathing, collapse or other potentially life-threatening symptoms, seek emergency medical care immediately.
Does Diabetes Mean You Will Develop Heart Disease?
No. Having diabetes does not mean that heart disease is inevitable.
However, diabetes increases cardiovascular risk, which makes prevention and risk-factor management particularly important.
The Heart Foundation recommends healthy lifestyle measures, managing blood pressure and cholesterol, taking prescribed medication and having regular Heart Health Checks to help reduce cardiovascular risk.
How Can You Reduce Diabetes-Related Heart Risk?
There are several practical areas to focus on.
Can Healthy Eating Help?
A heart-friendly eating pattern can include:
- Vegetables and fruit
- Wholegrains
- Legumes
- Nuts and seeds
- Fish
- Lean protein sources
- Healthier unsaturated fats
At the same time, limiting foods high in saturated fat, added sugars and excess salt can support overall cardiovascular health.
Dietary recommendations should be personalised, particularly for people managing diabetes.
Can Exercise Improve Heart Health?
Regular physical activity can support cardiovascular fitness, blood glucose management, blood pressure and overall wellbeing.
The Heart Foundation recommends being physically active for around 30 minutes on most days of the week as part of reducing cardiovascular risk in people with diabetes.
If you have known cardiovascular disease or symptoms during exercise, speak with your healthcare professional about the safest type and intensity of activity.
Should You Stop Smoking?
If you smoke, quitting is one of the most important steps you can take for cardiovascular health.
Smoking damages blood vessels and increases cardiovascular risk. When diabetes is also present, addressing modifiable risk factors becomes particularly important.
Do Diabetes Medicines Affect Heart Health?
Some diabetes medicines have cardiovascular benefits in specific patient groups, but treatment needs to be individualised.
Never start, stop or change medication without discussing it with your treating doctor.
What Does the Australian Data Tell Us About Diabetes and Heart Disease?
The connection between diabetes and cardiovascular disease is significant.
The Heart Foundation states that cardiovascular disease is the biggest cause of death among people with diabetes. It also reports that people with diabetes are approximately twice as likely to develop heart disease or experience a stroke.
The Heart Foundation additionally reports that people with diabetes can be up to four times more likely to experience a heart attack or stroke, depending on the comparison and risk profile.
These statistics do not mean that every person with diabetes will experience a cardiovascular event. Instead, they demonstrate why proactive risk assessment and prevention are important.
What Should You Ask Your Doctor About Your Heart Health?
If you have diabetes, consider discussing these questions with your healthcare professional:
What Are My Main Cardiovascular Risk Factors?
Ask about your:
- Blood pressure
- Cholesterol
- Blood glucose
- Weight
- Smoking status
- Family history
- Kidney health
- Physical activity
- Previous cardiovascular problems
Do I Need a Heart Health Assessment?
Your doctor can assess your overall cardiovascular risk and determine whether further testing or specialist assessment is appropriate.
Do I Need a Cardiologist?
If you have cardiovascular symptoms, established heart disease, multiple risk factors or an abnormal test result, your doctor may recommend specialist cardiology assessment.
How Can COR Cardiology Support Patients With Diabetes?
At COR Cardiology, cardiovascular assessment is focused on understanding the patient’s individual circumstances.
The practice provides specialist cardiovascular care in Ormeau and Pacific Pines and uses diagnostic technology to support assessment and treatment planning.
For a patient living with diabetes, cardiovascular assessment may involve reviewing:
- Medical history
- Blood pressure
- Cholesterol and triglycerides

- Lifestyle factors
- Overall cardiovascular risk
Depending on the clinical situation, a cardiologist may determine whether tests such as an ECG, echocardiogram, stress testing or other investigations are appropriate.
The goal is not to order every possible test. The goal is to identify the investigations that can provide useful information for that individual patient.
What Is the Best Way to Prevent Diabetes-Related Heart Disease?
The most effective approach is usually a combination of risk-factor management and healthy lifestyle habits.
This can include:
- Keeping diabetes under appropriate control
- Monitoring blood pressure
- Managing cholesterol
- Being physically active
- Eating a balanced, heart-friendly diet
- Maintaining a healthy weight where appropriate
- Avoiding smoking
- Taking prescribed medicines correctly
- Attending recommended health checks
- Discussing concerning symptoms promptly
Heart disease prevention is most effective when risk factors are identified and addressed early.
Conclusion: What Should Every Patient With Diabetes Monitor?
Managing diabetes means thinking about more than blood sugar. Cardiovascular health should also be part of the conversation.
Blood glucose, blood pressure, cholesterol, weight, lifestyle and family history can all contribute to an individual’s cardiovascular risk. Diabetes can increase the likelihood of heart disease and stroke, but many risk factors can be managed through healthy lifestyle choices, appropriate medical treatment and regular health assessments.
If you are concerned about diabetes-related cardiovascular risk, symptoms or an abnormal heart test, speak with your GP or an appropriately qualified cardiologist.
