5 Signs of Heart Failure Most People Mistake for Getting Older

By Curtis Jones · October 14, 2026

Getting winded on the stairs or noticing that your shoes feel tight by evening is easy to put down to age. Many people do exactly that. Those same changes can also be early signals that the heart is struggling to keep up.

Heart failure sounds like the heart has stopped. It hasn’t. The Centers for Disease Control and Prevention describes it as what happens when the heart cannot pump enough blood and oxygen to support other organs in your body, and stresses that it does not mean the heart has stopped beating.

The condition is widespread. According to the CDC, nearly 6.7 million adults 20 years old or older have heart failure in the United States. Cleveland Clinic lists age over 65 among the risk factors, along with high blood pressure, diabetes and coronary artery disease. It also notes that symptoms can range from mild to severe and sometimes come and go.

Here are five signs that often get blamed on getting older.

Running short of breath. The National Heart, Lung, and Blood Institute (NHLBI) says one of the first symptoms you may notice is feeling short of breath after routine activities like climbing stairs. As the heart weakens, it can happen while getting dressed or walking across a room. Some people have trouble breathing when they lie flat. The American Heart Association notes that some people need several pillows to prop themselves up at night.

Tired all the time. Fatigue is easy to dismiss. The American Heart Association describes a tired feeling all the time and difficulty with everyday activities, such as shopping, climbing stairs, carrying groceries or walking. The reason is that the heart can’t pump enough blood to meet the body’s needs, so blood is diverted away from less vital organs. One detail matters for older readers in particular. The NHLBI says older adults who do not get much physical activity may not experience shortness of breath. However, they may feel tired and confused.

Swollen ankles and a rising scale. Fluid that the heart can’t move tends to settle in the lower body. The AHA lists swelling in the feet, ankles, legs, fingers, stomach and other tissues and organs, adding that weight gain is common as a result. Sudden weight gain or loss, the AHA says, can be a sign that heart failure is developing or getting worse.

A cough that won’t go away. A lingering cough is usually blamed on allergies or a cold. With heart failure, fluid can back up into the lungs. The AHA describes persistent coughing or wheezing that can produce white or pink, blood-tinged mucus. Cleveland Clinic lists a dry, hacking cough among the symptoms.

Fuzzy thinking. Memory lapses rarely make people think of the heart. Yet the AHA lists memory loss and feelings of disorientation among the signs of heart failure and notes that a caregiver or relative may notice this first. Changes in blood levels of substances such as sodium can reduce blood flow to the brain.

Any one of these can have a simple explanation. Still, the AHA advises that if you have one or more symptoms of heart failure, even if you haven’t been diagnosed with heart problems, report them to your healthcare professional. Cleveland Clinic says a blood test for B-type natriuretic peptide, a substance the heart makes when it is working harder than usual, is one of the tests doctors can use.

Catching it early makes a difference. The CDC says early diagnosis and treatment can improve quality and length of life for people who have heart failure.
