Short Breath + Tired Legs?
These are signs you shouldn’t ignore.
When the heart struggles to pump efficiently, the body feels the impact:

• Less blood reaches your muscles
• Breathing becomes harder
• Walking becomes tiring
• Climbing stairs feels exhausting

These symptoms often develop slowly over months or even years and are easy to dismiss as “just getting older” or “being unfit.”
But if everyday activities are becoming harder, your heart may be asking for help.

Early detection can change outcomes.
Listen to your body. Don’t ignore the signs.

Repeat Hospital Visits? Here’s Why It Happens.
If you or someone you know has been hospitalised more than once for chest issues, breathlessness, infections, or fluid build-up, there may be underlying reasons:

• Blood pressure not fully controlled
• Heart pumping function weakening over time
• Fluid retention between visits
• Untreated inflammation
• Poor recovery after infection or hospitalisation

Many people don’t realise these symptoms progress slowly.
Early awareness can break the cycle of hospital admissions.

After being sick, your body needs time to recover.
But if weeks or even months have passed and breathing still feels difficult, your body may not be fully healed yet.

You might notice:
• Getting out of breath more easily
• Feeling tired most of the time
• Tightness or wheezing in your chest
• Struggling to walk as far as you used to

Your heart, lungs and immune system work together. When one is still recovering, the others have to work harder too.

👉 If symptoms keep lingering, don’t brush them off.
Your body may be asking for a little extra care.

Many people, especially women, brush these symptoms off, but they can be early signs that your heart is under strain or dealing with inflammation.

⚠️ Signs to pay attention to:
• A fast or pounding heartbeat
• Pressure or tightness in your chest
• Feeling like you can’t catch your breath
• Dizziness, especially during movement

These symptoms don’t always appear suddenly. They often build up quietly over time. If you’re noticing them more often, or they’re lasting longer than before, it’s worth paying attention.

💙 TREAD Research is currently running clinical studies and may be able to help you learn more about what’s happening with your heart.

⚠️ Swollen Feet or Ankles? Don’t Ignore It.
Swelling in the legs, feet, or even the stomach is often brushed off as “just water retention” but it can be an important sign that your heart may be under strain.

🚨 Signs to watch for:
• Shoes suddenly feeling tighter
• Deep sock marks on your legs
• Unexplained weight gain of 1–2 kg in a week
• Abdominal bloating

If you’ve noticed any of these changes, even occasionally, it’s important to pay attention. Your body may be trying to tell you something.

TREAD Research is currently running clinical trials for qualifying participants. If you’d like to find out whether you may be eligible:

Struggling to Breathe Easily? It Might Not Be Just Getting Older.
Getting out of breath quickly isn’t always normal. Sometimes it’s a sign your heart needs help.

🚩 Look out for:
• Getting out of breath on short walks
• Needing extra pillows to sleep comfortably
• Feeling puffed after small tasks
• A heavy or tight chest on the stairs

These can happen when your heart isn’t working as well as it should.

❤️ Don’t ignore it.
If breathing is becoming harder for you, it’s worth checking it early. Take part in one of our clinical research studies.
