Heart failure (HF) is frequently misdiagnosed, with rates varying significantly by setting, ranging from 16% in hospitals to nearly 69% when GPs refer patients, often mistaken for respiratory issues like COPD. Key challenges include overlapping symptoms (shortness of breath, fatigue) with other conditions, leading to delayed diagnosis, particularly in vulnerable groups like women and Black adults, and highlighting missed opportunities for early intervention.
Misdiagnosis of heart failure ranges from 16% to 68% depending on the setting. Patients with ischemic heart disease and lung disease are at risk of HF misdiagnosis. Patients with lung disease, stroke, and diabetes may benefit from screening for heart failure.
Worsening heart failure symptoms often involve increased shortness of breath (especially when lying down or sleeping), rapid weight gain from fluid buildup (like in legs, ankles, or abdomen), significant fatigue, a persistent cough with white/pink phlegm, increased swelling, heart palpitations, and mental confusion, signaling a need for prompt medical attention to prevent serious complications.
Go to your local emergency room or call 9-1-1 if you have: New chest pain or discomfort that's severe, unexpected, and comes with shortness of breath, sweating, nausea, or weakness. A fast heart rate (more than 120-150 beats per minute) -- especially if you are short of breath. Shortness of breath not relieved by rest.
For most people, heart failure is a long-term condition that can't be cured. But treatment can help keep the symptoms under control, possibly for many years.
BNP (B-type natriuretic peptides) tests – show the level of a hormone in your blood, which if elevated, can be a sign of heart failure.
Heart failure symptoms may include: Shortness of breath with activity or when lying down. Fatigue and weakness. Swelling in the legs, ankles and feet.
Symptoms can develop quickly (acute heart failure) or gradually over weeks or months (chronic heart failure).
Heart failure (HF), also known as congestive heart failure (CHF), is a complex clinical syndrome characterized by the heart's inability to pump blood effectively due to structural or functional impairments.
The hallmark feature of systolic heart failure is shortness of breath, also called dyspnea. A person with early systolic heart failure might get short of breath only when exercising. But a person with advanced systolic heart failure might have trouble breathing when simply walking across the room or even when resting.
Many people first realize their heart failure is getting worse when they notice gaining more than two or three pounds in a day or more than five pounds in a week. This gain may be due to retaining fluids since the heart is not working properly.
When to call 911 for Heart Failure
Symptoms of heart failure can range from mild to severe and may come and go. Unfortunately, congestive heart failure usually gets worse over time. As it worsens, you may have more or different signs or symptoms.
The symptoms of chronic kidney disease closely resemble heart failure. The symptoms of chronic kidney disease are often missed because it is a slowly developing health issue.
Tests for heart failure
an echocardiogram – a type of ultrasound scan where sound waves are used to examine your heart. breathing tests – you may be asked to blow into a tube to check whether a lung problem is contributing to your breathlessness; common tests include spirometry and a peak flow test.
Here are 10 drugs commonly prescribed for heart failure:
While exercise will not necessarily reverse heart failure on its own, it has helped many patients improve their heart health when combined with other therapies.
Stage C: People show symptoms of heart failure, including fatigue, breathlessness, and edema. However, edema may not be a prominent feature, or it may be milder and localized. Stage D: In stage D, edema becomes more apparent.
Surgery or other procedures for heart failure may include:
Symptoms of heart failure
fainting or feeling lightheaded. feeling very tired (fatigued) or weak at rest which gets worse with movement. shortness of breath when you're active or resting. swelling in your feet and ankles which can spread to your lower body.
Heart failure can progress. So, it has been broken down into four stages — A, B, C and D. When heart failure is in stage C or D, health care professionals also assign a classification. This classification measures a person's overall heart function and how bad the symptoms are.
Chronic heart failure patients also showed significantly lower gait speed, stride length, gait cycle and step length (p<0.05).
Frequently observed signs or symptoms, which can occur in isolation or in combination and can thus be used as “red flags” or warning signs include: Shortness of breath (dyspnea) or noticeably reduced exercise capacity. Chest pain (angina pectoris) Swollen feet or ankles (peripheral edema)
Chest discomfort or pain that lasts more than 15 minutes and does not improve with nitroglycerin or rest. It is important to monitor your weight. Weight gain is the first sign that your heart failure may be getting worse. Patients can gain up to 10 pounds of “extra” weight from fluid before feeling bad or swelling.
The blood gas exchange disorder and decreased cardiac output caused by pulmonary congestion and edema in chronic heart failure inevitably lead to a decrease in oxygen partial pressure and oxygen saturation.
