The symptoms of heart failure may vary and often resemble those of other medical conditions. If you have any unexplained symptoms, make an appointment with your doctor for an expert diagnosis.
In early stages of heart failure, some people with a weak heart don't experience any symptoms. This delays treatment and the heart failure worsens, resulting in symptoms such as:
Visible swelling of the legs and ankles, and occasionally, the abdomen
Dizziness, lightheadedness and fainting
Fatigue and weakness
Irregular or rapid heartbeats
Loss of appetite and nausea
Shortness of breath during rest, exercise, or lying flat
Heart Failure Diagnosis
Heart failure can be challenging to diagnose, because these symptoms can resemble symptoms of many other medical conditions. That is why it's important to receive care at an expert heart center that will get you an accurate diagnosis. Once you have a diagnosis, we can tailor your treatment plan appropriately.
