Keeping Your Heart Healthy: A Practical Lifestyle Guide

Heart Disease Is Largely Preventable

According to the Heart Foundation, up to 80% of premature heart disease and stroke is preventable through lifestyle changes. That is a remarkable statistic -- it means that for most people, the power to protect their heart is in their own hands.

The five pillars of heart-healthy living are maintaining a balanced diet, being physically active, not smoking, managing stress, and maintaining a healthy weight. None of these require dramatic changes -- consistent, small improvements add up to significant risk reduction over time.

Eating for Heart Health

A heart-healthy diet does not have to be complicated. The evidence consistently supports eating plenty of vegetables, fruit, and whole grains, choosing lean proteins including fish, legumes, and poultry, using healthy fats such as olive oil and avocado while limiting saturated and trans fats, reducing salt intake (most Australians consume far more than the recommended 5g per day), and limiting processed foods, sugary drinks, and excessive alcohol.

You do not need to follow a rigid diet plan. The Mediterranean-style eating pattern has the strongest evidence base for cardiovascular protection and is flexible enough to adapt to any cultural food preferences.

Physical Activity: How Much Is Enough?

The Heart Foundation recommends at least 150 minutes of moderate-intensity physical activity per week -- that is approximately 30 minutes on most days. Moderate intensity means you can talk but not sing during the activity. Walking, cycling, swimming, and gardening all count.

If you have not been active, start slowly and build up gradually. Even 10-minute sessions provide cardiovascular benefit. The key is consistency rather than intensity. Regular, moderate exercise reduces blood pressure, improves cholesterol, helps control blood sugar, reduces stress, and helps maintain a healthy weight.

If you have a heart condition or have not exercised in a long time, talk to your GP or cardiologist before starting a new exercise program.

Smoking and Your Heart

Smoking is one of the most significant risk factors for heart disease. It damages the lining of the arteries, accelerates plaque build-up, promotes blood clot formation, reduces oxygen in the blood, and raises blood pressure and heart rate.

The good news is that the cardiovascular benefits of quitting begin almost immediately. Within one year of quitting, your risk of heart disease drops by half. Within 15 years, your risk is similar to that of a non-smoker. Your GP can help with quit-smoking support and nicotine replacement therapy.

Managing Stress for Heart Health

Chronic stress contributes to heart disease both directly (through sustained elevation of stress hormones, blood pressure, and inflammation) and indirectly (through stress-related behaviours such as overeating, smoking, and physical inactivity).

Effective stress management looks different for everyone, but evidence-based approaches include regular physical activity, adequate sleep (7 to 9 hours for most adults), maintaining social connections, mindfulness or relaxation techniques, and seeking help when stress feels overwhelming.

When to See a Cardiologist

Even with a healthy lifestyle, some people develop heart problems due to genetic factors, age, or conditions they may not know about. You should ask your GP for a referral to a cardiologist if you experience chest pain, shortness of breath, palpitations, or dizziness, if your heart health check reveals moderate or high cardiovascular risk, if you have a family history of premature heart disease, or if you have diabetes with additional risk factors.

At Complete Heart Centre, all specialist consultations and cardiac diagnostic tests are fully bulk billed through Medicare. Prevention and early detection are always better than treating an advanced condition.
