How to check heart health? Everything you need to know

Overview

When you're young, heart health isn't always at the top of your mind. But looking after your heart isn't just about staving off problems down the road.

It's about ensuring that your heart is functioning at its best both now and into the future. You can think of it like this: your heart is the engine of your life, and regular check-ups and good fuel keep it running smoothly, taking you wherever you want to go.

Why does heart health matter so much?

Your heart beats tirelessly, delivering oxygen and nutrients to every part of your body. When it's not functioning optimally, everything else suffers.

Heart disease isn't just an "old person" problem. It can strike at any age, robbing you of energy, vitality, and even life itself.

When should I start getting checked out?

Both men and women should think about getting a baseline heart health check around age 30. It's like taking a "before" picture of your heart, so doctors can track any changes over time.

This makes it much easier to spot potential issues early on.

What are the early signs of heart trouble?

Heart disease has a reputation as a "silent killer" because its early symptoms can be subtle and easy to ignore. However, paying attention to your body's signals can help detect problems early.

Some common red flags include:

• Chest discomfort: This can range from pressure or squeezing to a dull ache or burning sensation. It may last a few minutes or come and go.
• Shortness of breath: Feeling breathless after minimal effort or even at rest could indicate reduced heart efficiency.
• Pain or discomfort elsewhere: This may appear in the arms, back, neck, jaw, or stomach.
• Nausea, light-headedness, or cold sweats: These symptoms may accompany chest discomfort or occur independently.
• Unexplained fatigue: Persistent tiredness or weakness, even after adequate rest, may signal an underlying heart issue.

If you experience any of these symptoms, seek medical advice promptly. However, if symptoms are severe or sudden, follow emergency instructions and call 000 immediately.

How often should I get tested?

The frequency of testing depends on individual risk factors such as family history, lifestyle, and existing health conditions.

If you are generally healthy, a check-up every 3–5 years is a good starting point. However, if you have concerns or your doctor recommends more frequent monitoring, it is important to follow their advice.

Prevention and early detection are key to maintaining long-term heart health.

What kind of tests can I expect?

Common heart health tests include:

• Blood pressure check: Measures the force of blood against artery walls. High blood pressure can strain the heart.
• Cholesterol check: A blood test that measures "good" and "bad" cholesterol levels.
• Blood sugar test: Screens for diabetes, which increases heart disease risk.
• Electrocardiogram (ECG): Records the heart’s electrical activity to detect irregular rhythms.
• Echocardiogram: An ultrasound that shows heart structure and function.
• Stress test: Assesses heart performance during physical activity.
• Coronary calcium scan: A CT scan that detects calcium buildup in arteries.
• Cardiac MRI: Provides detailed images of the heart and blood vessels.

Note: These diagnostic tests require an in-person clinical assessment and cannot be performed during a telehealth consultation.

Lifestyle tweaks for a healthy heart

Making small lifestyle changes can significantly improve heart health:

• Eat for your heart: Focus on fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit saturated fats, sodium, and added sugars.
• Stay active: Aim for at least 150 minutes of moderate exercise or 75 minutes of vigorous activity per week.
• Maintain a healthy weight: Excess weight increases strain on the heart.
• Quit smoking: Smoking damages blood vessels and significantly raises heart disease risk.
• Drink in moderation: Excess alcohol can elevate blood pressure and harm heart health.
• Manage stress: Chronic stress negatively impacts the heart. Practice relaxation techniques like meditation or exercise.
• Get enough sleep: Aim for 7–8 hours of quality sleep each night.

Can I check my heart health at home?

While nothing beats professional medical tests, you can keep tabs on certain aspects of your heart health at home:

• Check your pulse: Count the beats per minute at your wrist or neck. A normal resting heart rate is usually between 60 and 100.
• Monitor your blood pressure: Invest in a home monitor and check it regularly.
• Track your weight: Weigh yourself regularly and keep an eye on your BMI.
• Listen to your body: Pay attention to any unusual symptoms or changes in your energy levels.

Note: This information is for educational purposes only. You should consult a GP before attempting home monitoring or remedies to ensure they are safe and appropriate for your specific health profile.

What does a healthy heart look like?

A healthy heart is typically characterised by the following indicators:

• Normal blood pressure: Less than 120/80 mmHg
• Healthy cholesterol levels: Low “bad” cholesterol (LDL) and high “good” cholesterol (HDL)
• Normal fasting blood sugar levels: Within the recommended range <5.6 mmol/L
• Regular heart rhythm: No irregularities on an ECG, such as atrial fibrillation
• Normal heart structure and function: As seen on an echocardiogram or other imaging tests
• Good exercise tolerance: Ability to stay active without excessive fatigue or shortness of breath
• No symptoms of heart disease: No chest pain, shortness of breath, or other warning signs

How can I keep track of my heart health?

Tracking your heart health regularly can help detect early changes and maintain overall well-being:

• Keep a journal: Record your blood pressure, weight, exercise habits, and any symptoms.
• Use a fitness tracker or smartwatch: Many devices can monitor heart rate, activity levels, and sleep.
• Schedule regular check-ups: Visit your doctor for routine assessments and discuss any concerns.

When should I see a doctor right away?

If you or someone else experiences chest pain, severe shortness of breath, or sudden collapse, call 000 immediately or go to the nearest Emergency Department. Do not book an online consultation for emergency symptoms.

Seek immediate medical attention if you experience:

• Chest pain or discomfort: Especially if it is new, severe, or occurs with other symptoms.
• Shortness of breath: Particularly if it is sudden or worsens with activity.
• Fainting or light-headedness: This may indicate a serious underlying condition.
• Unexplained fatigue or weakness: Especially if persistent or accompanied by other symptoms.
• Swelling in legs, ankles, or feet: This may be a sign of heart failure.

Can an online doctor help?

Online doctors can provide general advice, medical certificates, and prescriptions where clinically appropriate. However, they cannot replace in-person examinations and diagnostic tests.

If you have concerns about your heart health, it is important to consult a qualified healthcare professional for proper diagnosis and treatment.

Conclusion

Your heart health should never be overlooked. By making it a priority, you are investing in your overall well-being and long-term health.

Remember, it is never too early or too late to start taking care of your heart.
