“I feel completely fine. Do I really need to worry about my heart?”

It is easy to think that a heart problem will always begin with severe chest pain.

But that is not always the case.

Some people may notice breathlessness, unusual tiredness, palpitations, dizziness, reduced exercise tolerance or chest discomfort. These symptoms may come and go and can sometimes be mistaken for stress, acidity, lack of sleep or simply getting older.

The important message is simple:

Don’t ignore changes that are new, unusual or persistent.

In 2026, the World Heart Federation’s campaign is “Don’t Miss a Beat,” focusing on recognizing signs of cardiovascular disease and taking action.

This World Heart Day, take a moment to understand your symptoms, know your risk factors and seek the right medical advice when something doesn’t feel normal.

What Is World Heart Day and Why Is It Celebrated?

World Heart Day is observed every year on September 29 to raise awareness about cardiovascular health and encourage people to take better care of their hearts.

The day highlights the importance of understanding heart disease risk factors, warning signs, and preventive measures. Conditions such as high blood pressure, diabetes, high cholesterol, and a family history of heart disease can increase your risk.

You don’t have to wait for a diagnosis or cardiac event to prioritise your heart health. Recognising changes in your health and seeking medical advice early can help you make informed decisions.

The 2026 campaign, “Don’t Miss a Beat,” reminds us to pay attention to changes in how we feel or how comfortably we can perform everyday activities—and to seek medical advice when something feels different.

Don’t Miss These Signs That Your Heart May Need Attention

Not every heart problem starts with severe chest pain.

Some symptoms can be mild, unusual or easy to explain away. That is why it is important to notice changes from your normal routine.

Chest Discomfort

Chest discomfort can feel different from person to person.

It can feel like pressure, tightness, squeezing, heaviness, or pain. It may also spread to the arms, back, neck, jaw, or upper abdomen.

Don’t ignore recurring or unexplained chest discomfort. Speak with a doctor to understand the cause.

If a doctor recommends cardiac testing, an ECG may be one of the tests used to assess the heart’s electrical activity. You can learn more about ECG testing at Atrius Cardiac Care and discuss whether it is appropriate for you with your doctor.

Breathlessness

Getting unusually breathless during an activity that previously felt normal is worth paying attention to.

For example:

“Earlier I could walk up two floors comfortably. Now I need to stop halfway.”

Breathlessness can have many causes.

It can be linked to heart, lung, fitness, anaemia, or other health conditions. Any new or worsening change should be discussed with a healthcare professional.

Unusual Tiredness

Everyone feels tired sometimes.

But persistent or unexplained fatigue is different.

If you are suddenly struggling with everyday activities that were previously easy, do not automatically blame it on a busy schedule or lack of sleep.

Unusual tiredness can occur with some heart problems, although it can also have many other causes.

A proper consultation can help determine whether your symptoms need further evaluation.

If you have several symptoms together, such as unusual fatigue with breathlessness, chest discomfort or dizziness, don’t simply wait for them to disappear.

Palpitations

Do you sometimes feel that your heart is:

• Racing?
• Pounding?
• Fluttering?
• Beating irregularly?

These sensations are called palpitations.

They can happen for several reasons, and many are not serious.

However, new, frequent or persistent palpitations deserve medical evaluation, particularly when they occur with chest discomfort, breathlessness, dizziness or fainting.

Depending on the situation, a doctor may recommend tests such as an ECG or longer-term heart rhythm monitoring.

Dizziness or Fainting

Occasional lightheadedness can happen for many reasons.

But repeated dizziness or unexplained fainting should not simply be ignored.

If dizziness occurs together with palpitations, chest discomfort or breathlessness, make sure you mention all of these symptoms during your consultation.

Reduced Exercise Tolerance

This is one of the easiest changes to overlook.

You may not have obvious chest pain.

Instead, you notice:

“Earlier I could climb two floors. Now I get tired after one.”

Or perhaps your usual morning walk suddenly feels much harder.

Maybe you need more breaks than before.

Maybe you become breathless doing activities that were previously comfortable.

These changes are worth noticing.

Reduced exercise tolerance does not automatically mean heart disease. But if the change is new or continues over time, tell your doctor.

A cardiovascular evaluation can help determine whether your symptoms are related to your heart or whether another explanation needs to be considered.

When Should You Get Your Heart Checked?

You do not need to assume that every symptom means you need a cardiac test.

The right evaluation depends on your age, symptoms, medical history and risk factors.

A cardiologist can review these factors and decide whether you need an ECG, echocardiography, blood tests, rhythm monitoring or another investigation.

If you have been noticing new symptoms or are concerned about your cardiovascular risk, you can contact Atrius Cardiac Care for a consultation.

Remember:

These symptoms do not automatically mean that you have heart disease.

Many of them can have other causes.

But new, persistent, worsening or concerning symptoms deserve medical attention.

And if you experience sudden severe chest discomfort, severe breathlessness, fainting or other symptoms that could indicate a heart attack, seek emergency medical care immediately.

Don’t wait for World Heart Day to listen to your heart. If something has changed, get it checked.

Heart Disease Can Be Silent — Know Your Risk Factors

“If I don’t have any symptoms, does that mean my heart is healthy?”

Not necessarily.

Some cardiovascular risk factors can develop quietly. You may feel completely normal while your blood pressure, cholesterol or blood sugar is gradually moving outside a healthy range.

Common factors that can increase cardiovascular risk include:

• High blood pressure
• High cholesterol
• Diabetes
• Smoking or tobacco use
• Physical inactivity
• An unhealthy diet
• Excess weight
• Family history of heart disease
• Increasing age

Some of these factors can be changed. Others, such as age and family history, cannot. But knowing your risk factors helps you and your doctor decide what needs attention.

Feeling healthy is good. Knowing your risk is better.

You do not necessarily need every possible heart test. The right health checks depend on your age, symptoms, medical history and risk factors.

5 Simple Things You Can Do for Your Heart

Taking care of your heart does not mean completely changing your lifestyle overnight.

Start with a few habits that you can actually maintain.

1. Move More

You don’t need to start with an intense workout.

Walking, cycling, swimming, dancing or simply becoming more active during the day can help you move more.

You could take a brisk walk after work, walk to nearby places or take short movement breaks if you have a desk job. The goal is to move more, not to become a gym expert.

2. Eat More Heart-Friendly Foods

Your everyday meals matter.

Try to include more:

• Vegetables
• Whole fruits
• Whole grains
• Dal and pulses
• Suitable protein sources
• Foods containing healthier unsaturated fats

At the same time, keep excess salt, sugary foods, fried foods and highly processed foods limited.

3. Stop Tobacco

If you smoke or use tobacco, quitting is one of the most important changes you can make for your cardiovascular health.

You don’t have to approach it alone.

If quitting has been difficult, speak with a healthcare professional about the support and options available to you.

The goal is not perfection. The goal is to stop exposing your heart to tobacco.

4. Sleep Properly

Good heart health also includes good sleep.

Try to maintain a regular sleep schedule and give yourself enough time to sleep each night.

Avoid making very late nights and consistently short sleep your normal routine.

If poor sleep has become a regular part of your lifestyle, treat it as something worth addressing rather than something you simply have to accept.

5. Know Your Numbers

Some important heart-health measurements can tell you about risks that you may not feel.

Depending on your individual situation, these may include:

• Blood pressure.
• Blood sugar

Regular monitoring can help identify changes and give you and your doctor a chance to decide what needs attention.

You don’t need to become obsessed with numbers.

If you are unsure which cardiac checks may be appropriate for you, it is better to discuss your risk factors with a doctor before booking tests on your own.

Can You Prevent Heart Disease?

Not every heart problem can be prevented. But many cardiovascular risk factors can be modified.

You cannot change your age or family history.

You may also have certain medical conditions that increase your risk.

But there are many things you can work on, including:

• Physical activity
• Diet
• Tobacco use
• Sleep
• Blood pressure
• Cholesterol
• Blood sugar
• Weight

Managing these factors can help reduce cardiovascular risk. Some people may improve certain risk factors through lifestyle changes, while others may also need medication or medical treatment.

The right approach depends on the individual.

The goal is risk reduction, not a guarantee.

You don’t have to wait until you have a heart problem to start taking care of your heart.

If you have several risk factors or are unsure about your cardiovascular health, a cardiology consultation at Atrius Cardiac Care can help you understand what needs attention and whether any further evaluation is appropriate.

When Should You See a Cardiologist?

Not everyone with one risk factor needs to see a cardiologist immediately.

But symptoms, multiple risk factors or a previous heart problem may make a medical evaluation appropriate.

Consider discussing your heart health with a doctor if you have:

• New or unexplained chest discomfort
• Breathlessness
• Frequent or concerning palpitations
• Dizziness or fainting
• Unusual or persistent fatigue
• Reduced exercise tolerance
• High blood pressure
• High cholesterol
• Diabetes
• A strong family history of heart disease
• Previous heart disease or a cardiac procedure

Your doctor can look at these factors together rather than judging your risk from one number or symptom alone.

Depending on your symptoms and medical history, the doctor may recommend investigations such as an ECG, echocardiogram, blood tests or heart-rhythm monitoring.

You can explore Atrius’s Diagnostic Services to understand the cardiac investigations available.

But don’t assume that you need a particular test just because you have one symptom.

Start with the right medical evaluation.

If you have symptoms or multiple cardiovascular risk factors, speak with a doctor about whether a cardiac evaluation is appropriate for you.

World Heart Day: What Can You Do Today?

World Heart Day is a good reminder to stop and ask yourself:

“What can I do for my heart today?”

You don’t need to completely change your lifestyle in one day.

Start with a few simple steps.

• Take a walk. Add some movement to your day. Even a short walk is a good place to start.
• Check your blood pressure. If you regularly monitor it, make a note of your readings and discuss unusual changes with your doctor.
• Avoid tobacco. If you smoke or use tobacco, consider getting professional support to quit.
• Choose a healthier meal. Add more vegetables, whole foods and suitable protein to your plate.
• Reduce excess salt. Pay attention to hidden salt in pickle, papad, namkeen, packaged foods and restaurant meals.
• Get enough sleep tonight. Give your body time to rest and recover.
• Don’t ignore a new symptom. If you have unexplained chest discomfort, breathlessness, palpitations, dizziness or unusual fatigue, speak with a doctor.

The World Heart Federation’s 2026 Keep the Beat campaign encourages people to move for 20 minutes a day during September. Walking, cycling, dancing and other forms of movement can all count.

You don’t need to make ten major changes today. Start with one.
