Heart failure doesn't always appear as chest pain or a sudden collapse. Most early signs are vague and often mistaken for stress, ageing, or minor health concerns. This is why high blood pressure is often referred to as a silent killer.
Dr. Arjun Mehta, a senior cardiologist at the Vital Heart Institute, Ahmedabad, explains, “Heart failure is a background disease where the heart fails to pump blood effectively. It can be treated—and even reversed—with the right procedures and lifestyle adjustments, if diagnosed early."
The problem is that most people overlook the early warning signs until it’s too late. They may seem benign, but these stealth signs could be your body waving a red flag.
Here are seven signs of heart failure so surprising that you should not ignore your risk:

1. Persistent Fatigue or Weakness
If you find that normal activities like climbing stairs or walking short distances tire you out, it may be a sign your heart isn’t delivering enough oxygenated blood to your muscles. This kind of tiredness develops gradually, making it easy to dismiss.
2. Swollen Legs, Ankles, or Feet (Edema)
Fluid retention is a common consequence of heart failure. When the heart struggles to circulate blood efficiently, fluid tends to accumulate in the lower extremities. If your shoes feel tighter or your ankles look puffy, don’t ignore it.
3. Difficulty Breathing (Especially When Lying Down)
One lesser-known sign is shortness of breath when lying flat, or needing several pillows at night to sleep comfortably. Dr. Mehta says, “This occurs when the heart isn’t pumping well and fluid begins to leak around the lungs.”
4. Frequent Urination at Night
Waking up multiple times at night to urinate can indicate your body is trying to get rid of the excess fluid retained during the day. While common with age, a sudden or worsening pattern should prompt a conversation with your doctor.
5. Rapid or Irregular Heartbeat

A weakened heart may try to compensate by beating faster or irregularly. This can feel like fluttering, pounding, or skipping beats. Left untreated, persistent arrhythmias can develop into tachycardia and lead to life-threatening complications.
6. Unexplained Weight Gain
Sudden weight gain—about 2–3 pounds (0.9–1.4 kg) in a day or 5 pounds (2.3 kg) in a week—can indicate fluid buildup. It’s easy to overlook until clothes feel tighter or the scale shows a jump.
7. Persistent Cough or Wheezing
A dry, hacking cough that worsens at night may mean fluid is collecting in your lungs. In more severe cases, it may produce pink or blood-tinged mucus—an urgent sign that requires immediate medical attention.
