Getting winded on the stairs. Ankles that puff up by evening. A dry cough that will not quit. In many older adults, symptoms like these get chalked up to age.
The real driver may be a heart losing its ability to pump. National figures compiled by the Heart Failure Society of America put the current adult burden at about 6.7 million people, and project the number will climb to 8.7 million by 2030.
Heart failure is progressive, and delay costs. Symptoms often start subtle, then intensify. The National Heart, Lung, and Blood Institute notes that the first sign may simply be feeling short of breath after routine activities like climbing stairs. Sedentary older adults may skip the breathlessness altogether and present with fatigue or mental confusion instead.
The 8 signs to know
1. Shortness of breath. Trouble breathing during ordinary activities, when lying flat, or at rest is one of the most common warning signs. The NIH's MedlinePlus describes it as feeling like you cannot get enough air, particularly when climbing stairs.

2. Swelling in the ankles, legs or abdomen. When the heart pumps less efficiently, fluid backs up in the veins and pushes into surrounding tissue. NHLBI lists swelling in the lower extremities, the abdomen and the veins of the neck among the hallmark symptoms.
3. Unusual fatigue. Tiredness that persists even after rest is a signature symptom, per NIH sources. Everyday tasks like carrying groceries or making a bed can feel disproportionately hard.
4. Persistent cough or wheezing. Fluid buildup in the lungs can trigger a dry hacking cough, sometimes producing white or pink-tinged mucus. That is why doctors often use the term congestive heart failure.
5. Rapid weight gain from fluid retention. The American Heart Association's clinical guidance flags 2 to 3 pounds of weight gain in a single day, or more than 5 pounds in a week, as a signal of worsening congestion. That is water, not fat. Daily weigh-ins are a standard self-management tool.

6. Nausea or loss of appetite. When the digestive system receives less blood and fluid backs up around the liver and gut, people may feel full quickly, lose their appetite or feel queasy even without eating much.
7. Confusion or impaired thinking. Reduced blood flow to the brain can lead to trouble focusing, memory lapses or disorientation. A scientific statement from the American Heart Association reports that almost half of people with heart failure experience some cognitive impairment affecting language, memory or executive function.
8. Rapid or irregular heartbeat. A weakened heart often tries to compensate by beating faster. Patients may notice palpitations, a racing pulse or a fluttering sensation in the chest.
When to call 911
Most heart failure signs unfold gradually and warrant a same-week call to a clinician. Some do not.

Call 911 for sudden severe shortness of breath at rest, chest pain or pressure lasting more than a few minutes, coughing up pink or foamy mucus, fainting, or sudden confusion. Those are signs of an acute cardiac event, not a slow decline.
Because the earliest signs look so much like aging, delays in seeking care are common. Anyone experiencing new breathlessness on ordinary exertion, unexplained puffy ankles or a rapid jump on the scale should talk to a doctor sooner rather than later. Heart failure is a chronic condition, but treatment can slow its progression and control symptoms.
