Early detection of heart disease symptoms is important.

Many people know that chest pain and shortness of breath are common signs of heart disease. However, there are some symptoms that can be mistaken for the common cold.

According to experts, there are four symptoms of cardiovascular disease that can be misdiagnosed as flu. They are fatigue, nausea, fever and sweating, according to Express .

Fatigue . The British Heart Foundation (BHF) lists “extreme tiredness” as a sign of heart failure and heart problems.

Professor David Newby, from the BHF, said: “A lot of my patients have fatigue, whether they have heart failure or not, whether they have angina or not. It’s hard to differentiate because it’s not specific.

Persistent fatigue can also sometimes signal heart failure or coronary artery disease, adds Harvard Medical School.

But fatigue does not necessarily mean there is a heart problem, it can just be due to staying up late or working too much.

BHF recommends: If you feel extremely tired for no reason, you should see a doctor promptly.

Nausea . According to the Mayo Clinic, nausea can be a sign of coronary artery disease, which is more common in women than men. In addition to chest discomfort, women are more likely to experience other symptoms, such as shortness of breath, nausea, and extreme fatigue.

Fever . This is often a sign of the flu. But fever is also an early warning sign of heart failure, according to Express.

Symptoms of heart failure can range from mild to severe. In the early stages, you may experience flu-like symptoms, including fever or chills. Heart failure can also cause body aches in the early stages.

Fever is also a sign of myocarditis.

The Mayo Clinic says: Common symptoms of myocarditis are also very similar to the flu, such as headache, body aches, joint pain, fever or sore throat, according to Express.

Sweating. While sweating is normal, it can also signal heart disease, according to the BHF.

If you sweat while exercising or in hot weather, there's nothing to worry about. But feeling hot and sweaty with chest pain is a sign you should call an ambulance, according to Express .
