Warning Signs of Heart Failure: What You Shouldn’t Ignore

Heart failure is a serious condition that affects millions of Americans every year. It occurs when the heart can’t pump blood efficiently enough to meet the body’s needs. While it doesn’t mean the heart has stopped working completely, it does require timely medical attention to prevent complications and improve quality of life.

At BASS Medical Group, we believe in empowering patients with the knowledge they need to take charge of their health. Here’s what to know about the early warning signs of heart failure—and when to schedule a check-up.

What Is Heart Failure?

Heart failure means the heart’s ability to pump blood is weaker than normal. This results in a buildup of fluid in the lungs, legs, or abdomen, and causes fatigue due to poor oxygen circulation. It can be caused by coronary artery disease, high blood pressure, diabetes, or previous heart damage from a heart attack.

Heart failure can happen suddenly (acute) or develop slowly over time (chronic). Either way, early detection is key.

5 Common Symptoms of Heart Failure

Recognizing these early signs of heart failure could lead to earlier treatment—and better long-term outcomes.

1. Shortness of Breath (Dyspnea)

One of the most common symptoms, especially during physical activity or while lying flat. If you find yourself getting winded doing simple tasks, your heart may not be pumping enough oxygen-rich blood.

2. Fatigue and Weakness

Constant tiredness or difficulty completing normal activities can occur when your heart is unable to meet the energy needs of your body. Fatigue may be more noticeable later in the day or after exercise.

3. Swelling in the Legs, Ankles, or Abdomen (Edema)

When the heart doesn’t circulate blood efficiently, fluid can build up in the extremities or abdomen. This swelling may leave indentations in the skin and worsen by evening.

4. Persistent Cough or Wheezing

A chronic, hacking cough—especially with frothy or blood-tinged mucus—may be a sign of fluid accumulation in the lungs due to congestive heart failure.

5. Rapid or Irregular Heartbeat (Palpitations)

If your heart frequently races, skips beats, or pounds without exertion, your cardiovascular system may be under stress. Heart failure is often linked with arrhythmias like atrial fibrillation.

Diagnostic Tools: What to Expect

If your doctor suspects heart failure, they may recommend an echocardiogram, a non-invasive ultrasound that shows how well your heart is pumping. A key measurement is ejection fraction (EF)—a healthy EF ranges from 55% to 70%. Lower values may indicate heart failure or another cardiac condition.

Other tests may include:

  • Blood tests (BNP or NT-proBNP levels)
  • Chest X-rays
  • Electrocardiogram (ECG)
  • Cardiac MRI or CT

Can Heart Failure Be Prevented?

Yes—while not all cases are preventable, many risk factors can be managed through lifestyle changes and regular healthcare.

Heart-Healthy Habits to Practice:

  • Eat a heart-healthy diet: Focus on lean protein, whole grains, vegetables, and low-sodium options.
  • Stay active: Aim for at least 30 minutes of moderate exercise 3–5 days a week.
  • Stop smoking: Smoking damages blood vessels and increases heart failure risk.
  • Manage existing conditions: Keep high blood pressure, diabetes, and cholesterol under control.
  • Reduce stress: Chronic stress elevates blood pressure and heart strain. Try yoga, meditation, or deep breathing.
